200422114 玖、發明說明：【發明所屬之技術領域】本發明係關於交叉軋輥軋製機及使用此交叉軋輥軋製機之軋製方法。【先前技術】交叉軋輥軋製機之特徵為，於將上下工作軋輥形成為交叉的狀態下來軋製被軋製材料。圖1 2 ( a )、圖1 2 ( b )顯示上下工作軋輥與被軋製材料的位置關係。圖1 2 ( a )為俯視圖，圖1 2 ( b )為側視圖。如圖1 2 ( a )所示，上下工作軋輥 1 0 1係將被軋製材料S的寬幅方向中央部作為交叉中心（交叉點）c而S己置為以指定的交叉角0 (可變）而交叉之狀態。藉此，如圖1 2 ( b )所示，在交叉點c附近的上下工作軋輥1 0 1的開口度a與軋輥端附近的上下工作軋輥1 0 1的開口度b產生差值，上下工作軋輥1 0 1的開口度的有關於被軋製材料S的寬幅方向的分布，係如圖1 3所示成為二次曲線。若增大交叉角β ，則該二次曲線之下凸程度的傾斜變陡，若減小交叉角0 ，則該二次曲線之下凸程度的傾斜變緩。若交叉角0為0時，則上下工作軋輥的開口度成為一定。交叉軋輥軋製機出現以前之軋製機，在其軋製中，如圖 1 4 ( a )所示，因為軋製荷重的作用而引起的上下工作軋輥 1 0 1及上下背托輥1 0 2的彎曲，被軋製材料S的板厚分布具有寬幅中央部厚而寬幅端緣變薄的傾向。但是，在交叉軋輥軋製機中，藉由將前述的交又角0設定為最佳值，使 5 312/發明說明書(補件)/93-05/93107638 200422114 上下工作軋輥1 〇 1的開口度形成為最佳的二次曲線，用以補償上下工作軋輥1 〇 1及上下背托輥1 0 2的彎曲量，使其如圖1 4 ( b )所示，可使被軋製材料S軋製後的寬幅方向板厚分布接近均勻，而可提高板厚精度。因此，近年來，無論是熱軋製或是冷軋製，均傾向設置多臺交叉軋輥軋製機。圖1 5顯示交叉軋輥軋製機的主要構成的概要。在此，稱配置有驅動上下工作軋輥1 0 1的馬達之一側為驅動側，而稱其相反側的操作人員進行作業側的部分為操作側。上工作軋輥1 0 1的旋轉軸係藉由驅動側與操作側的一對上工作軋輥軸承座1 0 3而支持為可旋轉。下工作軋輥1 0 1的旋轉軸係藉由驅動側與操作側的一對下工作軋輕軸承座1 0 4 而支持為可旋轉。另外，配置於上工作軋輥1 0 1上方的上背托輥1 0 2的旋轉軸係藉由驅動側與操作側的一對上背托輥軸承座1 0 5而支持為可旋轉。配置於下工作軋輥1 0 1下方的下背托輥1 0 2的旋轉軸係藉由驅動側與操作側的一對下背托輥軸承座1 0 6而支持為可旋轉。在該交叉軋輥軋製機中，與以前的軋製機不同，具有以從被軋製材料S的搬運方向及其反方向抱入上下背托輥軸承座1 0 5、1 0 6及上下工作軋輥軸承座1 0 3、1 0 4的形式配置的交叉頭1 0 7、1 0 8，藉由沿圖1 5中大箭頭所示之被軋製材料S的搬運方向驅動該交叉頭1 〇 7、1 0 8，聯合驅動上工作軋輥1 0 1及上背托輥1 0 2、下工作軋輥1 0 1及下背托幸昆1 0 2，以設定為前述的交叉角0 。將如圖1 5所示之聯合驅動上工作軋輥1 0 1及上背托輥 6 312/發明說明書(補件)/93_05/93107638 200422114 1 0 2、下工作軋輥1 0 1及下背托輥1 0 2的方式稱為成對交叉方式，並稱僅僅驅動上下工作軋輥1 0 1的方式為工作軋輥單獨交叉方式。另外，稱在驅動側與操作側的任一方配置交叉頭，使配置有交叉頭側進行交叉，並使其方反側成為枢軸的方式為單交叉方式（在上軋輥的驅動側具有交叉頭時，在下軋輥的操作側具有交叉頭）。圖1 5所示之交叉軋輥軋製機係圖示相當於此者，其中，以從被軋製材料S的搬運方向及其反方向抱入配置於上工作軋輥1 0 1及上背托輥1 0 2的驅動側的上工作軋報軸承座1 0 3及上背托報軸承座1 0 5的形式，配置交叉頭1 0 7，並以從被軋製材料S的搬運方向及其反方向抱入配置於下工作軋輥1 0 1及下背托輥1 0 2的操作側的下工作礼親軸承座1 0 4及下背托報軸承座1 0 6的形式，配置交叉頭1 0 8。與此相反，也可於上工作軋輥及上背托輥的操作側、下工作軋輥及下背托輥的驅動側配置交叉頭。另外，稱在上下均為驅動側與操作側的兩方配置交叉頭，以使兩方的交叉頭交叉，且未設置樞軸的方式為雙交叉方式。以下，說明成對交叉方式且單交叉方式的情況，但作為其基本機能，在工作軋輥單獨交叉方式、雙交叉方式也與此等相同，因此本發明所稱之交叉軋輥軋製機係包含有此等。圖1 6 ( a )、圖1 6 ( b )顯示從操作側所視之圖1 5之交叉軋輥軋製機的概要圖。該交叉軋輥軋製機係採成對交叉方式且單交叉方式。在該交叉軋輥軋製機中，以從被軋製材料 7 312/發明說明：*(補件)/93-05/93107638 200422114 S的搬運方向及其反方向抱入配置於上工作軋輥1 〇 1及上背托輥1 0 2的驅動側的上工作軋輥軸承座1 0 3及上背托輥軸承座1 0 5的形式配置一對交叉頭（未圖示）。另外，以從被軋製材料S的搬運方向及其反方向抱入配置於下工作軋輥1 0 1及下背托輥1 0 2的操作側的下工作軋輥軸承座1 〇 4 及下背托輥軸承座1 0 6的形式配置一對交叉頭1 0 8。在此，各交叉頭1 0 8係被支持為可相對於軋製機機殼1 〇〇沿被軋製材料的搬運方向自由移動。各交叉頭1 〇 8的驅動係藉由螺合於軋製機機殼1 0 0上固定的螺帽11 6的螺桿 1 1 5而進行。在各交叉頭1 0 8的下工作軋輥軸承座1 0 4側的相向部，如圖16(b)所示，於水平方向（圖16(b)中的上下方向）以一定的曲率形成彎曲面Τ。在各下交叉頭襯套筒 1 1 3形成對應於此的彎曲面Τ。彎曲面Τ與交叉頭1 0 8於水平方向頂接而可自由轉動。另一方面，下交叉頭襯套筒113 係由其平面部頂接於下工作軋輥軸承座1 0 4上所設的軸承座襯套筒1 1 7。另外，在各交叉頭1 0 8的下背托輥軸承座 1 0 6側的相向部，也於水平方向形成以一定的曲率彎曲的與前述實曲面Τ相同的彎曲面。形成有對應於此的彎曲面 Τ的各下交叉頭襯套筒1 1 4，係由其平面部頂接於下背托輥軸承座1 0 6上所設之未圖示的軸承座襯套筒，同時，另一面的彎曲面Τ與交叉頭1 0 8於水平方向頂接而可自由轉動。各交叉頭1 0 8與交叉頭襯套筒1 1 3、1 1 4係藉由形成彎曲面Τ的滑動面彼此的相互滑動，形成為可改變交叉角0 的構造。以從被軋製材料S的搬運方向及其反方向抱入配 8 3丨2/發明說明書(補件)/93-05/93107638 200422114 置於上工作軋輥1 0 1及上背托輥1 0 2的驅動側的上工作軋輥軸承座1 0 3及上背托輕軸承座1 0 5的形式配置的交叉頭，也分別具有與交叉頭1 0 8相同的構造，在與上工作軋輥軸承座1 0 3及上背托輥軸承座1 0 5的相向部形成有彎曲面Τ，同時，在此等彎曲面Τ分別設有具有彎曲面的交叉頭襯套筒（未圖示）。另一方面，以與配置於上工作軋輥1 0 1的操作側的上工作軋輥軸承座1 0 3相向的方式，於軋製機機殼1 0 0上設有一對的上工作軋輥樞軸塊1 0 9。在各上工作軋輥樞軸塊1 0 9 的上工作軋輥軸承座1 0 3側的相向部，於水平方向以一定的曲率形成彎曲面Τ，而形成有對應於此的彎曲面Τ的各上工作軋輥樞軸塊襯套筒1 1 〇，係由其平面部頂接於上工作軋輥軸承座1 0 3上所設之未圖示的軸承座襯套筒，同時，另一面的彎曲面Τ與上工作軋輥樞軸塊1 0 9於水平方向頂接而可自由轉動。另外，以與配置於上背托輥1 0 2的操作側的上背托輥軸承座1 0 5相向的方式，於軋製機機殼 1 0 0上設有一對的上背托輥樞軸塊1 1 1。在各上背托輕樞軸塊1 1 1的上背托輥軸承座1 0 5側的相向部，於水平方向以一定的曲率形成彎曲面Τ，形成有對應於此的彎曲面Τ的各上背托輥樞軸塊襯套筒1 1 2，係由其平面部頂接於上背托輥軸承座1 0 5，同時，另一面的彎曲面Τ與上背托輥樞軸塊11 1於水平方向頂接而可自由轉動。另外，在下工作軋輥1 0 1及下背托輥1 0 2的驅動側，也設有下工作軋輥樞軸塊、下工作軋輥枢軸塊襯套筒、下背托輥樞軸塊及下背 9 312/發明說明書(補件)/93-05/9310763 8 200422114 托輥樞軸塊襯套筒。但是，一般情況下，以軋製機進行的被軋製材料s的軋製中，如專利文獻1所揭示，上下均將工作軋輥1 0 1相對於背托輥1 0 2而偏向被軋製材料S的搬運方向。在此，稱此為偏位，在圖1 6 ( a)中，相對軋製機中心的工作軋輥的偏位量為C1，而背托輥的偏位量為C 2。一般稱C1與C 2 的合計為偏位量。藉由偏位，以便使其在被軋製材料S的搬運方向的圖16(a)中的箭頭e方向產生水平方向分力（亦稱偏位分力）。箭頭e方向係與工作軋輥偏位之方向一致。另外，在上下背托輥1 0 2，在與被軋製材料S的搬運方向相反的箭頭f方向產生水平方向分力。箭頭f方向係與背托輥偏位之方向一致。於是，將上下工作軋輥軸承座1 0 3、 1 0 4向被軋製材料S的搬運方向抵壓，並將上下背托輥軸承座1 0 5、1 0 6向其相反方向抵壓，上下工作軋輥軸承座 1 0 3、1 0 4被頂接於被軋製材料S的搬運方向出口側的軋製機機殼1 0 0，上下背托輥軸承座1 0 5、1 0 6被頂接於被軋製材料S的搬運方向入口側的軋製機機殼1 0 0，而達成穩定。但是，如圖16(a)、圖16(b)所示，因為在各軋親軸承座1 0 3、1 0 4、1 0 5、1 0 6與軋製機機殼1 0 0之間（正確而言是在設於上工作軋輥軸承座1 0 3的軸承座襯套筒與工作軋輥樞軸塊襯套筒1 1 0之間、在設於下工作軋輥轴承座1 0 4 的軸承座襯套筒1 1 7與交叉頭襯套筒1 1 3之間、在上背托輥軸承座1 0 5與上背托輥樞軸塊襯套筒1 1 2之間、及在下背托輥軸承座1 0 6與下交叉頭襯套筒1 1 4之間），具有間隙 10 312/發明說明書(補件)/93-05/9310763 8 200422114 d，因此若不進行各軋親軸承座1 0 3、1 0 4、1 0 5、1 0 6於被軋製材料S的搬運方向的定位，則在軋製荷重小、亦即偏位造成的施壓力小的軋製進行時，在改變交叉角0的情況等中，在軋製機機殼1 0 0内，上下工作軋輥軸承座1 〇 3、 1 0 4或上下背托輥軸承座1 0 5、1 0 6會在被軋製材料S的搬運方向或其相反的方向產生位置偏移，若其左右（驅動側與其相反側的操作側）有不均勻的現象，便將在被軋製材料S 的寬幅方向之左右產生上下工作軋輥1 0 1的開口度差，因此有被軋製材料S蛇行、彎曲之問題，特別嚴重的情況時形成破裂斷開的問題。為防止此等情況的產生，提出如專利文獻2及專利文獻 3所揭示，由油壓汽缸將軸承箱（軋輥軸承座）頂向被軋製材料的搬運方向的裝置，或如專利文獻4所揭示，預測軋製荷重造成的軋製機機殼的收縮量，以使軋輥軸承座與軋製機機殼的間隔最小化的方法。在此，軋製機機殼收縮係指如圖1 7 ( b )所示般，藉由在軋製進行中作用於軋製機機殼的上下方向的軋製荷重，在機殼上下方向中央部所產生的被軋製材料於搬運方向的變形，亦即，機殼的入口側與出口側的間隔的收縮。專利文獻1 :曰本專利特開平8 -

[Prior Art] A cross roll mill is characterized in that the material to be rolled is rolled in a state where the upper and lower working rolls are formed to cross. Figures 12 (a) and 12 (b) show the positional relationship between the upper and lower work rolls and the material being rolled. Fig. 12 (a) is a top view, and Fig. 12 (b) is a side view. As shown in Fig. 12 (a), the upper and lower work rolls 1 0 1 use the center in the width direction of the rolled material S as the intersection center (cross point) c, and S has been set at a specified intersection angle 0 (may Change) and cross state. Thereby, as shown in FIG. 12 (b), the opening degree a of the upper and lower working rolls 1 0 1 near the intersection point c and the opening degree b of the upper and lower working rolls 1 0 1 near the roll end generate a difference, and the upper and lower workings are performed. The opening degree of the rolls 101 is related to the distribution in the width direction of the material S to be rolled, and is a quadratic curve as shown in FIG. 13. If the cross angle β is increased, the inclination of the convexity under the quadratic curve becomes steeper. If the cross angle 0 is decreased, the inclination of the convexity under the quadratic curve becomes slower. When the crossing angle 0 is 0, the opening degree of the upper and lower work rolls becomes constant. Cross rolling mills appeared before the rolling mills. During their rolling, as shown in Figure 14 (a), the upper and lower working rolls 1 0 1 and the upper and lower back rollers 1 0 caused by the rolling load. In the bending of 2, the plate thickness distribution of the rolled material S tends to be thick at the wide central portion and thin at the wide end edges. However, in the cross-roller rolling mill, the opening angle of 5 312 / Invention Specification (Supplement) / 93-05 / 93107638 200422114 for opening and lowering the work roll 1 〇1 is set by setting the aforementioned crossing angle 0 to an optimal value. The degree is formed into an optimal quadratic curve, which is used to compensate the bending amount of the upper and lower work rolls 〇01 and the upper and lower back rollers 102, so that as shown in FIG. 14 (b), the rolled material S can be made. The thickness distribution in the wide direction after rolling is nearly uniform, which can improve the thickness precision. Therefore, in recent years, whether it is hot rolling or cold rolling, a plurality of cross roll rolling mills have tended to be installed. Figure 15 shows an outline of the main configuration of a cross roll mill. Here, one of the motors configured to drive the upper and lower work rolls 101 is called the driving side, and the part on the opposite side where the operator performs work is called the operating side. The rotating shaft of the upper work roll 110 is supported to be rotatable by a pair of upper work roll bearing housings 103 on the drive side and the operation side. The rotating shaft of the lower work roll 1 0 1 is supported to be rotatable by a pair of lower work rolling light bearing blocks 1 0 4 on the driving side and the operating side. In addition, the rotating shaft of the upper back roller 102 arranged above the upper work roll 101 is supported to be rotatable by a pair of upper back roller bearing blocks 105 on the driving side and the operating side. The rotating shaft of the lower back roller 10 arranged below the lower work roll 1 0 1 is supported to be rotatable by a pair of lower back roller bearing holders 10 on the driving side and the operating side. This cross-roller rolling mill is different from the conventional rolling mill in that it has the upper and lower back-up roller bearing housings 105, 106, and up-and-down operations that are held in the conveying direction of the material to be rolled S and its opposite direction. The cross heads 1 0 7 and 1 8 arranged in the form of roll bearing seats 10 3 and 10 4 are driven by the cross head 1 in the conveying direction of the rolled material S shown by the large arrow in FIG. 15. 7, 1 0, 8 jointly drive the upper work roll 1 0 1 and the upper back support roller 10 2, the lower work roll 1 0 1 and the lower back support 1 10 2 to set the aforementioned cross angle 0. The upper work roll 1 0 1 and the upper back roller 6 shown in FIG. 15 are jointly driven. 312 / Invention Specification (Supplement) / 93_05 / 93107638 200422114 1 0 2. The lower work roll 1 0 1 and the lower back roller. The 10 2 method is called a pairwise cross method, and the method of driving only the upper and lower work rolls 1 0 1 is called the work roller single cross method. In addition, it is said that a cross head is arranged on either the driving side or the operation side, and the method in which the cross head is arranged to cross and the opposite side is pivoted is a single cross method (when the cross roller is provided on the drive side of the upper roll , Has a cross head on the operating side of the lower roll). The cross-roller rolling mill shown in FIG. 15 is equivalent to this, in which the upper work rolls 101 and the upper back-up rolls are held by being placed in the conveying direction of the material to be rolled S and its opposite direction. On the drive side of the 102, the upper work rolling bearing housing 103 and the upper back rolling bearing housing 105 are arranged with cross heads 10 and 7 in a direction from the conveying direction of the rolled material S and its reaction. It is held in the direction of the lower working roll 1 0 1 and the lower backing roller 1 0 2 and is arranged in the form of a lower working bearing housing 104 and a lower backing bearing housing 10 6. The cross head 1 0 is arranged. 8. In contrast, the crossheads may be arranged on the operation side of the upper work roll and the upper back roller, and on the drive side of the lower work roll and the lower back roller. In addition, it is said that the crossheads are arranged on both the drive side and the operation side so that the crossheads on the two sides intersect and the pivot is not provided as the double cross method. In the following, a case of a paired cross method and a single cross method will be described, but as its basic function, the work roll single cross method and double cross method are also the same.

However, in general, in the rolling of the material s to be rolled by the rolling mill, as disclosed in Patent Document 1, the work rolls 1 0 1 are biased toward the rolled side with respect to the backing rolls 1 2. Transport direction of material S. Here, this is called offset. In Fig. 16 (a), the offset amount of the work roll relative to the center of the rolling mill is C1, and the offset amount of the back-up roll is C2. The total of C1 and C 2 is generally called the offset. The displacement is performed so as to generate a horizontal component force (also referred to as an offset component force) in the direction of the arrow e in FIG. 16 (a) in the conveying direction of the rolled material S. The direction of the arrow e is consistent with the deviation of the work rolls. In addition, in the upper and lower back rollers 102, a horizontal component force is generated in an arrow f direction opposite to the conveyance direction of the material S to be rolled. The direction of the arrow f is the same as that of the back-up roller. Then, the upper and lower working roller bearing holders 10, 3, and 10 are pressed against the conveying direction of the rolled material S, and the upper and lower back roller bearing holders are pressed against the opposite directions. The work roll bearing housings 1 0 3, 1 0 4 are abutted against the rolling machine housing 1 0 0 on the exit side in the conveying direction of the rolled material S, and the upper and lower back roller bearing housings 1 5 5 and 1 6 are topped. The rolling machine housing 100 connected to the entrance side of the rolled material S in the conveying direction is stabilized. However, as shown in Fig. 16 (a) and Fig. 16 (b), it is because each of the rolling bearing housings 1 0 3, 1 0 4, 1 0 5, 10, 6 and the rolling machine housing 1 0 0 (To be exact, the bearing is located between the bearing sleeve bushing of the upper work roll bearing seat 103 and the work roll pivot block bushing 1 1 0, and the bearing provided at the lower work roll bearing seat 10 4 Between the seat bushing 1 1 7 and the cross head bushing 1 1 3, between the upper back roller bearing seat 105 and the upper back roller pivot block bush 1 1 2, and between the lower back bracket Between the roller bearing seat 1 0 6 and the lower cross head bushing 1 1 4), with a gap of 10 312 / Invention Specification (Supplement) / 93-05 / 9310763 8 200422114 d. Positioning of 1 0 3, 1 0 4, 1 0 5, 1 0 6 in the conveying direction of the rolled material S, when the rolling load is small, that is, the rolling force caused by the deviation is small, In the case of changing the crossing angle 0, etc., within the rolling mill housing 100, the upper and lower working roll bearing housings 10 and 10, or the upper and lower back roller bearing housings 105, 106 may be rolled. The material S is transported in the opposite direction or a position shift occurs, The left and right sides (the driving side and the opposite side of the operating side) are uneven, and the opening degree difference of the upper and lower work rolls 1 1 1 will be generated around the width direction of the material S to be rolled, so there is a material to be rolled. The problem of S meandering and bending, especially in severe cases, the problem of rupture and disconnection. In order to prevent such situations, a device for pushing a bearing housing (roller bearing housing) toward a conveying direction of a rolled material by a hydraulic cylinder is proposed as disclosed in Patent Documents 2 and 3, or as disclosed in Patent Document 4. It is revealed that a method of predicting the shrinkage of the rolling mill casing caused by the rolling load so as to minimize the interval between the rolling bearing housing and the rolling mill casing. Here, as shown in FIG. 17 (b), the rolling machine casing shrinkage means that the rolling load acting on the rolling machine casing in the vertical direction during the rolling process is centered in the vertical direction of the casing. The deformation of the material to be rolled in the conveyance direction caused by the portion, that is, the gap between the entrance side and the exit side of the casing shrinks. Patent Literature 1: Japanese Patent Laid-Open No. 8-1 9 7 1 1 0 Patent Literature 2: Japanese Patent Laid-open No. 9-2 8 5 8 0 6 Patent Literature 3: Japanese Patent Laid-Open No. 2 0 0 1- 1 1 3 3 0 Patent Document 4: Japanese Patent Laid-Open Publication No. 7-3 2 0 1 8 However, as in the above-mentioned Patent Document 2 and Patent Document 3, oil pressure steam 11 312 / Invention specification ( (Supplement) / 93-05 / 93 丨 07638 200422114 In the way that the cylinder bears the roller bearing seat toward the rolling machine housing, it is necessary to install a hydraulic cylinder in a very small place, so it becomes a special cylinder structure.

In addition, the piping for supplying hydraulic pressure to the hydraulic cylinder is necessary to pass through the rolling material without interfering with the space for the rolling mill housing and the roller bearing housing. In addition, a space for piping support is required. In addition, in combination with the special cylinder structure of the hydraulic cylinder mentioned above, problems of reliability such as oil leakage easily occur, and costs of repair or maintenance. In addition, in order to ensure the repair time, there is a problem that the operating rate of the equipment is reduced. Usually around the hot rolling mill, there is a large amount of cooling water for rolls, cooling water for rolling bearings, etc. It is preferable to arrange the lubricant supply port in the sliding portion between the bearing housing and the casing or between the bearing housing and the hydraulic cylinder in such a manner that the lubricant does not flow by using cooling water. However, in order to arrange the lubricant supply port in the sliding portion between the roll bearing seat and the hydraulic cylinder, the lubricant supply hole must be penetrated in the hydraulic cylinder. In addition, if the hydraulic cylinder abuts against the roller bearing seat, the sliding pressure increases, and the amount of wear of the bearing seat liner sleeve and the cylinder surface increases, so the cost for repairs also increases. In addition, as in the above-mentioned Patent Document 4, in a method of predicting the amount of shrinkage of the rolling machine casing caused by the rolling load to minimize the interval between the roll bearing housing and the rolling machine casing, the rolling load is small In the case where the amount of deformation of the casing is small, the gap between the roller bearing housing and the rolling machine casing remains, 12 3 丨 2 / Invention Specification (Supplement) / 93-05 / 93107638 200422114 The space between the roller bearing support and the rolling mill housing is completely stabilized, but the housing is sandwiched by the housing, and the equipment is in trouble, etc. Based on this, the present invention is based on the above-mentioned supply of a simple structure, the installation cost Rolling in the gap of the rolling bearing housing using this cross roll rolling machine [Content of the invention] 1.

為防止上工作軋報軸承座的位置偏移，在被軋製材料的搬運方向入口側的交叉頭襯套筒，設有向軋製機機殼 3 0 (被軋製材料的搬運方向出口側）逼迫上工作軋輥軸承座的軸承座限制裝置（未圖示）。換言之，在被軋製材料的搬運方向入口側的交叉頭襯套筒，設有向被軋製材料軋製進行中上工作軋輥1偏位的方向逼迫上工作軋輥軸承座的軸承座限制裝置。該軸承座限制裝置係具有與操作側的軸承座限制裝置1 8相同的構成。另外，為防止上背托輥軸承座的位置偏移，在被軋製材料的搬運方向出口側的交叉頭襯套筒，設有向軋製機機殼3 0 (被軋製材料的搬運方向入口侧）逼迫上背托輥軸承座的軸承座限制裝置（未圖示）。該轴承座限制裝置係具有與操作側的軸承座限制裝置2 2相同的構成。根據以上說明之交叉軋輥軋製機的第2實施形態，藉由彈簧2 1、2 5的簡單機構，除了上下工作軋輥軸承座3、4 外，還進一步將上下背托輕軸承座5、6向軋輥偏位方向（例如，將工作軋輥軸承座3、4向被軋製材料的搬運方向，將背托輥軸承座5、6向其相反方向）逼迫，藉以防止各軋輥軸承座3、4、5、6的間隙内的位置偏移，可防止被軋製材料的蛇行、彎曲、破裂斷開等的故障。另外，藉由直接將潤滑劑供給彈簧保持器與軸承座襯套筒的滑動部，潤滑劑 200422114 不會因乳親冷卻水、軸承座冷卻水等的冷卻水而流動，可維持良好的潤滑狀態，並可減低彈簧保持器、襯套筒類的補修維護所需的費用。以下，詳細說明利用彈簧2 5不僅將上下工作軋輥軸承座3、4，還將上下背托輥軸承座5、6向軋製機機殼3 0逼迫的方法為較好方法的理由。In order to prevent the position shift of the bearing housing of the upper work, the crosshead bushing at the entrance side of the rolled material conveying direction is provided with a rolling machine casing 3 0 (the conveying direction of the rolled material outlet side ) Forcing the bearing block limiting device (not shown) of the upper work roll bearing block. In other words, the crosshead bushing at the entrance side in the transport direction of the rolled material is provided with a bearing seat restraining device for urging the upper work roll 1 in a direction in which the upper work roll 1 is shifted during the rolling of the rolled material. This bearing block limiting device has the same configuration as the bearing block limiting device 18 on the operation side. In addition, in order to prevent the position of the upper back roller bearing seat from being shifted, the crosshead bushing at the exit side of the rolled material conveying direction is provided to the rolling machine casing 30 (the conveying direction of the rolled material). (Inlet side) The bearing block restricting device (not shown) of the upper back roller bearing block is forced. This bearing block limiting device has the same structure as the bearing block limiting device 22 on the operation side. According to the second embodiment of the cross-roller rolling machine described above, the simple mechanism of the springs 21, 25, in addition to the upper and lower working roll bearing seats 3, 4, further supports the upper and lower back light bearing seats 5, 6 Forcing the rolls in an offset direction (for example, moving the work roll bearing housings 3 and 4 to the conveying direction of the material to be rolled and the backing roll bearing housings 5 and 6 in the opposite direction) to prevent the roll bearing housings 3 and 4 The position deviation in the gaps of 5, 5, and 6 can prevent the troubles such as meandering, bending, cracking and breaking of the rolled material. In addition, since the lubricant is directly supplied to the sliding portion of the spring holder and the bearing housing bushing, the lubricant 200422114 does not flow due to cooling water such as milk cooling water and bearing housing cooling water, and can maintain a good lubrication state. And can reduce the cost required for repair and maintenance of spring retainers and bushings. In the following, the reason why the spring 25 is not only used to press the upper and lower working roll bearing housings 3 and 4 but also the upper and lower back roller bearing housings 5 and 6 to the rolling machine housing 30 is explained in detail as a reason.

上下工作軋輥軸承座3、4或上下背托輥軸承座5、6，係如圖4所示，具有在與上工作軋輥樞軸塊襯套筒1 0、交叉頭襯套筒1 3、上背托輥樞軸塊襯套筒1 2、交叉頭襯套筒 1 4之間的間隙d中，於被軋製材料的搬運方向或其相反方向產生位置偏移，而造成上工作軋輥1與上背托輥2或下工作軋輥1與下背托輥2之間的平行度的破壞，上工作軋輥1與上背托輥2或下工作軋輥1與下背托輥2微小交叉的情況。上工作軋輥1與上背托輥2的交叉角稱為軋輥交叉角。或是，下工作軋輥1與下背托輥2的交叉角稱為軋輥交叉角。若發生有如此之軋輥交叉角，則在上下工作軋輥1、上下背托輥2間產生偏向軸方向的力（推力）。圖3顯示軋輥交叉角與推力係數（由推力除以軋製荷重值）的關係。在成對交叉軋製機中，工作軋輥1與背托輥2 在正常情況下，其各自的中心軸具有平行的位置關係，但是，若參照圖3可知，伴隨著平行度的破壞的微小軋輥交叉角的變動，推力係數發生極大變化。因此若略微增大軋輥交叉角，將有產生極大之推力的情況。如圖4所示，軋製機係在各軋輥軸承座3、4、5、6與 200422114 樞軸塊襯套筒或交叉頭襯套筒1 0、1 3、1 2、1 4之間具有隙d，軋輥交叉角為可變動。該依間隙d之軋輥交叉角變動通常不可控制。例如，在前述圖1 ( a )、圖1 ( b )及習例的圖1 4 ( a )、圖1 4 ( b )所示的軋製機的例子中，在軋製最大產生有0 . 0 4度的軋輥交叉角。圖5顯示下工作軋輥1與下背托輥2交叉的情況的軋交叉角與差荷重及推力的關係。在此，「差荷重」係指從作側的荷重減去驅動側的荷重所得的差。如圖5所示，使在0.04度的軋輥交叉角也產生有1200kN的推力。該推力係如圖6所示，係使在軋製機的前視圖内用以衡欲旋轉各軋輥1、2的力矩的操作側及驅動側的差荷重化。如圖5所示，在推力為1 2 0 0 k N時，差荷重變化為 6 0 0 k N。在差荷重變化為6 0 0 k N時，若軋製機機殼的垂直向的彈簧係數為1 5 0 0 0 k N / m m時，在操作側及驅動側的垂方向（軋製荷重的作用方向）的延伸差產生約4 0 // m( = 600/15000x 1000)。於是，假定如圖6所示，作為正軋製被軋製材料S中的情況，即使被軋製材料S通過上工作軋輥1的寬幅方向之中心，因為差荷重的補償，因必須將驅動側的上下工作軋輥1的開口度收縮相當於該 // Π1程度的量。通常，操作人員在軋製被軋製材料時，採用在軋製某軋製材料後，查看開始下一被軋製材料的軋製時的差荷的變化，將其調整為應成為零的等級（上下工作軋輥的操側及驅動側的開口度差）的方法。然而，在如交叉軋輥軋 312/發明說明書(補件)/93-05/93107638 間的知中輥操即平變方直在下此 40 被重作製 27 200422114The upper and lower working roller bearing seats 3, 4 or the upper and lower back roller bearing seats 5, 6 are shown in FIG. 4 and have upper and lower working roller pivot block bushings 10, cross head bushings 1 and 3. In the gap d between the back support roller pivot block sleeve 1 2 and the cross head sleeve sleeve 1 4, a position shift occurs in the conveying direction of the rolled material or the opposite direction, which causes the upper work roll 1 and The parallelism between the upper back roll 2 or the lower work roll 1 and the lower back roll 2 is broken, and the upper work roll 1 and the upper back roll 2 or the lower work roll 1 and the lower back roll 2 are slightly intersected. The intersection angle of the upper work roll 1 and the upper back roller 2 is referred to as a roll intersection angle. Alternatively, the intersection angle of the lower work roll 1 and the lower back roller 2 is referred to as a roll intersection angle. If such a roll crossing angle occurs, a force (thrust force) deviating in the axial direction is generated between the upper and lower work rolls 1 and the upper and lower back rollers 2. Figure 3 shows the relationship between the roll crossing angle and the thrust coefficient (divided by the thrust divided by the rolling load value). In a paired cross rolling mill, the work rolls 1 and the back-up rolls 2 normally have a parallel positional relationship between their respective central axes. However, referring to FIG. 3, it can be seen that the micro rolls are accompanied by the destruction of parallelism. The change of the crossing angle greatly changes the thrust coefficient. Therefore, if the roll crossing angle is slightly increased, there may be a case where a great thrust force is generated. As shown in FIG. 4, the rolling mill is provided between each of the roller bearing seats 3, 4, 5, 6, and 200422114 pivot block bushings or cross head bushings 10, 1, 3, 1, 2, and 14. The gap d and the roll crossing angle are variable. The variation of the roll crossing angle depending on the gap d is usually uncontrollable. For example, in the example of the rolling mill shown in Fig. 1 (a), Fig. 1 (b), and Figs. 14 (a) and 14 (b) of the conventional example, a maximum of 0 is produced during rolling. 0 4 degree roll crossing angle. Fig. 5 shows the relationship between the rolling angle and the differential load and thrust when the lower work roll 1 and the lower back roller 2 cross. Here, the "difference load" refers to the difference obtained by subtracting the load on the driving side from the load on the working side. As shown in FIG. 5, a thrust of 1200 kN is also generated at a roll crossing angle of 0.04 degrees. This thrust is shown in Fig. 6, and the differential load on the operation side and the drive side for balancing the torque to rotate each of the rolls 1, 2 in the front view of the rolling mill is increased. As shown in FIG. 5, when the thrust is 1 2 0 0 k N, the difference load changes to 6 0 0 k N. When the differential load change is 600 kN, and if the vertical spring coefficient of the rolling mill casing is 15 00 kN / mm, the vertical direction (rolling load The difference in extension of the action direction produces about 4 0 // m (= 600 / 15000x 1000). Therefore, it is assumed that, as shown in FIG. 6, as the case where the material S to be rolled is being rolled, even if the material to be rolled S passes through the center in the width direction of the upper work roll 1, because of the compensation of the differential load, it is necessary to drive the The shrinkage of the opening degree of the upper and lower work rolls 1 on the side is equivalent to this amount. Generally, when rolling a material to be rolled, the operator adjusts it to a level that should be zero after checking the change in the differential load at the beginning of rolling of the next material to be rolled after rolling a material to be rolled. (The difference between the opening degree of the operating side and the driving side of the upper and lower working rolls). However, in the knowledge such as the cross-rolling 312 / Invention Specification (Supplement) / 93-05 / 93107638, the roll operation is to flatten the square, and the next 40 is reworked 27 200422114

機般工作軋輥軸承座3、4或背托輥軸承座5、6於被軋製材料的搬運方向的位置偏移因上述理由而發生，並由伴隨藉此所產生的軋親交叉角的推力生成有差荷重的狀態，僅在依推力的差荷重的量，其應取得等級值也發生變化。而且，在前述間隙d中，工作軋輥軸承座3、4或背托輥軸承座5、6的位置並不固定，而為可變動。如此般，若工作軋幸昆軸承座3、4或背托親軸承座5、6的位置在間隙d内變動時，即便在以相同條件軋製相同交叉角β 、相同尺寸的被軋製材料的情況，推力、差荷重及應取得之等級值均喪失再現性。因而，即使在該狀態繼續進行軋製，仍於被軋製材料產生彎曲或蛇行，尤其是在如熱軋製的間歇性地軋製的情況、或更壞時，成為被軋製材料尾端拉入的原因。The position shift of the machine-like work roll bearing seats 3, 4 or the back roller bearing seats 5, 6 in the conveying direction of the rolled material occurs due to the above reasons, and is caused by the thrust force accompanying the rolling cross angle generated by this In a state where a differential load is generated, only the amount of the differential load depending on the thrust force changes the level value to be obtained. In addition, in the aforementioned gap d, the positions of the work roll bearing seats 3, 4 or the back-up roller bearing seats 5, 6 are not fixed and can be changed. In this way, if the position of the work rolling bearing housings 3 and 4 or the back bracket pro bearing housings 5 and 6 changes within the gap d, the rolled material with the same cross angle β and the same size is rolled under the same conditions. In the case of thrust, thrust, differential load and the grade value that should be obtained all lose reproducibility. Therefore, even if rolling is continued in this state, bending or meandering occurs in the material to be rolled, and in particular, when it is intermittently rolled such as hot rolling, or worse, it becomes the tail end of the material to be rolled. Reason for pulling in.

因此更好之方法是利用彈簧2 5不僅將上下工作軋輥軸承座3、4，還將上下背托輥軸承座5、6向軋製機機殼3 0 的方向逼迫，以防止各軋輥軸承座3、4、5、6在間隙d 内的位置偏移。其可極力抑制上下工作軋輥1與上下背托輥2的交叉角（軋輥交叉角）的產生，極力抑制伴隨此的推力的產生，可更為有效地防止被軋製材料的蛇行、彎曲、破裂斷開等的故障。其次，參照圖1 ( a )及圖2 ( a )說明將工作軋輥1與背托輥2組入軋製機内或拔出時的狀況。工作軋輥1與背托輥2係於垂直於圖1 ( a )及圖2 ( a )之紙面的方向組入或拔出。在組入或拔出工作軋輥1與背托輥2時，為防止機械干擾，交叉頭8係經由使相互螺合中 200422114 的螺桿1 5及螺帽1 6中的螺桿1 5側旋轉，以從軋輥軸承座 4、6離開2〜5 in m的方式開放。接著，在組入工作軋輥1與背托輥2後，交叉頭8閉合，彈簧保持器1 9與軸承座襯套筒1 7、彈簧保持器2 3與軸承座襯套筒2 6之間隙，被設定成為零。彈簧保持器1 9與薄襯套筒2 0、彈簧保持器2 3與薄襯套筒2 4之間隙，在作用有軋製荷重時，考慮到軋製機機殼3 0如圖1 7 ( b )所示般向上述間隙的變狹方向收縮的情況，係設定為1 . 0 m m〜 2 . 0 m m。在作用有軋製荷重時，配合軋製機機殼3 0的收縮，該間隙變小，彈簧.2 1、2 5被壓縮在與軋輥軸承座4、6之間。作為在該壓縮狀態作用於彈簧21、2 5的力，1個軸承座最好為2 0 0〜3 0 0 k N。若低於2 0 0 k N，則將軋輥軸承座4、 6向軋製機機殼30的方向逼迫的力不夠充分，而若超過 3 0 0 k N時，則有過大的力施加於軋親軸承座4、6内的未圖示的軸承的旋轉而有損傷其之虞。為充分發揮本發明之軸承座限制裝置1 8的機能，潤滑相當重要。潤滑部分係在彈簧保持器1 9與軸承座襯套筒 1 7之間及交叉頭8與交叉頭襯套筒1 3之間。尤其是，交叉頭8與交叉頭襯套筒1 3係於彎曲面狀滑動面彼此相互滑動的面供給潤滑劑，此點相當重要。又，在第1實施形態及第2實施形態的任一形態中，雖均顯示僅由操作側、驅動側中任一個單側軋輥軸承座向被軋製材料的搬運方向入口側、出口側移動的單交叉軋製機，但在將交叉角變更時成為旋轉中心的樞軸塊9、1 1等 29 312/發明說明書(補件)/93-05/93107638 200422114 固定於軋製機機殼3 0上，如交叉頭8般組入、拔出工作軋輥1與背托輥2的軋製機内時，便無法開放上述間隙。藉此，樞軸塊9、1 1側的彈簧保持器與軋輥軸承座3、5側的軸承座襯套筒的各間隙，可防止與對工作軋輥1及背托-輥 2的軋製機内進行組入、拔出時的各軋輥軸承座3、5的干擾，因此在未作用軋製荷重的狀態只要產生略微的間隙即可。該間隙最好為0 . 2〜1 . 0 m m。若低於0 . 2 m m，在將工作軋輥1及背托輥2組入、拔出軋製機内時則有干擾之虞，若超過1 . 0 mm，在作用軋製荷重的情況，即使軋製機機殼 3 0收縮，彈簧保持器仍舊無法到達各軋輥軸承座3、5的軸承座襯套筒，有不能施加其逼迫力之虞。在第1實施形態及第2實施形態的任一形態中，該間隙均被設為0 . 4 m m。 (實施例）針對在圖7所示之熱軋製生產線4 0的精加工軋製機4 6 的第1〜第7台（F1〜F7)上應用本發明之圖1(a)、圖1(b) 所示之成對交叉軋製機（僅設置逼迫工作軋輥軸承座的軸承座限制裝置）進行軋製的情況，與應用習知之圖1 6 ( a)、圖1 6 ( b )所示成對交叉軋製機進行軋製的情況，比較下工作軋輥軸承座的位置偏移量進行評價。在圖7所示熱軋製生產線4 0中，元件符號41為加熱爐，4 2為精壓加工壓合機（sizing press)、43為粗軋製機、44為端剪機（crop shear)、45為除鏽（descaling)裝置、47為冷卻區、48為捲取裝置。圖8顯示第4台F 4的軋製荷重與成為交叉頭側之操作 30 312/發明說明書(補件)/93-05/93107638 200422114 側的下工作軋輥軸承座的位置偏移量（搬運方向入口側）的關係。又，本實施例之第4台的工作軋輥直徑約為6 3 0 mm，背托輥直徑約為1 5 5 0 m m，交叉角為0 . 0 2〜1 . 0 4度，軋製速度為350〜550mpm。參照圖8，在設置軸承座限制裝置前，亦即應用習知之組合交叉軋製機的情況，在軋製中，在軋製機機殼1 0 0内，下工作軋輥軸承座1 〇 4在被軋製材料的搬運方向入口側產生最大為1 . 2 m m程度的位置偏移。相對於此，在設置軸承座限制裝置後，亦即應用本發明之圖1 ( a )、圖1 ( b )所示成對交叉軋製機的情況，與軋製荷重無關，其下工作札報軸承座4的位置偏移在0 . 1 m m以下。可知可防止下工作軋幸昆軸承座4的位置偏移。又，下工作軋輥軸承座4、1 0 4的位置，如圖1 0所示，係在薄襯套筒2 0内埋設渦流式距離感測器5 0，經由測定該渦流式距離感測器5 0與下工作軋輥軸承座4、1 0 4的距離來求得。將渦流式距離感測器5 0的輸出信號取入放大器 5 1内，藉由放大器5 1的輸出，可經常性地監視下工作軋輥軸承座4、1 0 4的活動。再者，針對在圖7所示之熱軋製生產線4 0的精加工軋製機46的第1〜第7台（F1〜F7)上應用本發明之圖1(a)、圖1 ( b)所示之成對交叉軋製機（僅設置逼迫工作軋輥軸承座的軸承座限制裝置）及圖2 ( a )、圖2 ( b )所示之成對交叉 200422114 況，與應用習知之圖1 6 ( a )、圖1 6 ( b )所示之成機進行軋製的情況，比較並檢討差荷重的誤差圖9顯示第4台F4的實際熱軋製作業中的差荷重的關係。在未設置軸承座限制裝置的情用習知之圖1 6 ( a )、圖1 6 ( b )所示之成對交叉. 況，發現有接近6 0 0 k N的差荷重。相對於此，工作軋輥·軸承座的軸承座限制裝置的情況，亦明之圖1 ( a )、圖1 ( b )所示之成對交叉軋製機白‘ 荷重的誤差減低為4 0 0 k N。另外，在同時設置幸昆轴承座的轴承座限制裝置及逼迫背托親軸承限制裝置的情況，亦即應用本發明之圖2 ( a)、之成對交叉軋製機的情況，其差荷重的誤差減以下。以上，說明了在熱軋製生產線上應用本發明例如本發明也可應用於圖1 1所示之冷軋製線軋製機6 6。在圖1 1中，元件符號6 1為入口偵 6 5、6 7為拉緊軋輥、6 3為焊接機，6 4為供料斷機、6 9為捲緊盤。另外，本發明還可應用於外的雙交叉之成對交叉軋製機、工作軋輥單獨ί (產業上之可利用性）如上述說明，根據本發明之交叉軋輥軋製機叉軋輥軋製機之軋製方法，藉由彈簧的簡單機輥軸承座向軋輥偏位方向逼迫，藉以防止工作在間隙内的位置偏移，可防止被軋製材料的蛇 312/發明說明書(補件)/93-05/93107638 ，對交叉軋製〇軋製荷重與 •況，亦即應軋製機的情在設置逼迫即應用本發 0情況，其差逼迫工作軋座的軸承座圖2(b)所示低為1 5 0 k Ν 的例子，但 6 0的精加工 ί迴路、62、盤，68為剪除單交叉以之叉軋製機。及使用此交構將工作軋軋親軸承座行、彎曲、 32 200422114 破裂斷開等的故障。另外，因此除工作軋親軸承座外，還將背托親軸由彈簧的簡單機構向軋輥偏位方向逼迫，以防止各承座在間隙内的位置偏移，而極力抑制工作軋親與的交叉角（軋親交叉角）的產生，並極力抑制伴隨此的產生，可更為有效地防止被軋製材料的蛇行、彎裂斷開等的故障。另外，作為逼迫工作軋I昆軸承座或進一步逼迫背機構，藉由使用彈簧可避免一定要在不致干擾軋製及軋輥軸承座的狹窄空間設置油壓汽缸及油壓配管難，因此可成為廉價且可靠度高的裝置。更且，藉將潤滑劑供給彈簧保持器與軸承座襯套筒的滑動部劑無因軋輥·冷卻水、軸承座冷卻水等的冷卻水而流況，可維持良好的潤滑狀態，並可減低彈簧保持器筒類的補修維護所需的費用。【圖式簡單說明】圖1 ( a )顯示本發明之交叉軋輥軋製機的第1實施圖1 ( a )為從操作側所視之交叉軋輥軋製機的概要圖 1(b)為圖1(a)中之A-A箭視圖。圖2 ( a )顯示本發明之交叉軋輥軋製機的第2實施圖2 ( a )為從操作側所視之交叉軋輥軋製機的概要圖 2(b)為圖2(a)中之B-B箭視圖。圖3為顯示相對於工作軋親與背托親的交叉角（幸i 叉角）的推力係數的變化的曲線圖。 312/發明說明書(補件)/93-05/93107638 承座藉軋輥軸背托輥的推力曲、破托輥的機機殼的困由直接，潤滑動的情、襯套形態，，圖形態，，圖，輥交 33 200422114 圖4為顯示工作軋輥軸承座或背托輥軸承座產生有位置偏移的狀況的俯視圖。圖5為顯示工作軋輥軸承座或背托輥軸承座發生有位置偏移的情況中所產生的差荷重與推力的關係的曲線圖。圖6為顯示產生有推力的情況中軋製機的前視圖内所發生的力矩的狀況圖。圖7為熱軋製線的概要構成圖。圖8為顯示第4台（stand)F4的軋製荷重與成為交叉頭側之操作側的下工作軋輥•軸承座的位置偏移量的關係的曲線圖。圖9為顯示第4台F4的實際熱軋製作業中的軋製荷重與差荷重的關係的曲線圖。圖1 0為測定下工作軋I昆軸承座的位置的裝置構成的說明圖。圖1 1為冷軋製線的概要構成圖。圖1 2 ( a )、圖1 2 ( b )為交叉軋輥軋製機的原理說明圖。圖1 3為顯示上下工作軋輥之開口度的有關被軋製材料的寬幅方向的分布圖圖1 4 ( a )為習知軋製機的說明圖。圖1 4 ( b )為交叉軋輥軋製機的原理說明圖。圖1 5為交叉軋輥軋製機的主要構成的概要構成圖。圖1 6 ( a )顯示習知例的交叉軋輥軋製機，圖1 6 ( a )為從操作側所視之交叉軋輥軋製機的概要圖，圖1 6 ( b )為圖 16(a)中之A-A箭視圖。 34 3 ] 2/發明說明書(補件)/93-05/93107638 200422114 圖1 7 ( a )、圖1 7 ( b )為顯示.軋製機機殼的變形狀況的圖。 (元件符號說明） a 開 π 度 b 開 V 度 c 交叉中心 (交叉點） Cl〜 C2 偏位量 d 間隙 F 1〜 F7 第 1 第 7 台 S 被軋製材料 T 彎曲面 Θ 交叉角 1 上下工作軋輥 2 上下背托輥 3 上工作軋輥軸承座 4 下工作軋輥軸承座 5 上背托輥軸承座 6 下背托輥軸承座 8 交又頭 9 上工作軋輥樞轴塊 10 上工作軋輥樞轴塊襯套筒 11 上背托輥樞轴塊 12 上背托輥樞軸塊襯套筒 13 下交叉頭襯套筒 14 下交叉頭襯套筒 312/發明說明書(補件)/93-05/93107638Therefore, a better method is to use the springs 2 5 not only to press the upper and lower working roller bearing seats 3, 4 but also to press the upper and lower back roller bearing seats 5 and 6 toward the rolling machine housing 30 to prevent each roller bearing seat. The positions of 3, 4, 5, and 6 within the gap d are shifted. It can minimize the occurrence of the cross angle (roller cross angle) of the upper and lower work rolls 1 and the upper and lower back rollers 2 and can suppress the generation of the thrust force accompanying it, and can more effectively prevent the material from rolling, bending and cracking. Disconnection, etc. Next, a description will be given of a situation when the work rolls 1 and the back-up rolls 2 are put into the rolling mill or pulled out with reference to Figs. 1 (a) and 2 (a). The work roll 1 and the back support roll 2 are assembled or pulled out in a direction perpendicular to the paper surface of Fig. 1 (a) and Fig. 2 (a). When the work roll 1 and the back roller 2 are assembled or pulled out, in order to prevent mechanical interference, the crosshead 8 is rotated by the side of the screw 15 of the screw 2216 and the screw 15 of the nut 16 in the mutual screwing. Open 2 ~ 5 in m away from the roller bearing holders 4 and 6. Next, after the work roll 1 and the back support roll 2 are assembled, the cross head 8 is closed, and the gap between the spring retainer 19 and the bearing bushing sleeve 17 and the spring retainer 2 3 and the bearing bushing sleeve 2 6 Is set to zero. The gap between the spring retainer 19 and the thin-lined sleeve 20, the spring retainer 23 and the thin-lined sleeve 24, when the rolling load is applied, consider the rolling machine casing 3 0 as shown in Figure 1 7 ( b) The case of shrinking in the narrowing direction of the gap as shown in the figure is set to 1.0 mm to 2.0 mm. When a rolling load is applied, in accordance with the shrinkage of the rolling machine casing 30, the gap becomes smaller, and the springs 2 and 25 are compressed between the rolling bearing seats 4 and 6. As the force acting on the springs 21 and 25 in this compressed state, it is preferable that one bearing block is 2000 to 300 kN. If it is lower than 2000 kN, the force for pressing the roll bearing housings 4 and 6 in the direction of the rolling machine casing 30 is insufficient. When it exceeds 300 kN, excessive force is applied to the rolling mill. Rotation of a bearing (not shown) in the pro-bearing housings 4 and 6 may damage it. In order to give full play to the function of the bearing block limiting device 18 of the present invention, lubrication is very important. The lubricating part is connected between the spring retainer 19 and the bearing housing bushing 17 and between the crosshead 8 and the crosshead bushing 13. In particular, it is important that the crosshead 8 and the crosshead bushing 13 are supplied with lubricant to the surfaces where the curved surface-shaped sliding surfaces slide on each other. Moreover, in any of the first and second embodiments, it is shown that only one of the operation side and the driving side is moved from the one-side roll bearing housing to the entrance side and the exit side of the material to be rolled in the conveying direction. Single cross rolling mill, but the pivot block 9, 1 1 etc. which becomes the center of rotation when the crossing angle is changed 29 312 / Invention Specification (Supplement) / 93-05 / 93107638 200422114 Fixed to the rolling machine casing 3 The above gap cannot be opened when the work rolls 1 and the back-up rolls 2 are assembled and pulled out like the cross head 8. As a result, the gaps between the spring holders on the pivot block 9, 1 side and the bearing housing bushings on the roll bearing seats 3, 5 can be prevented from interfering with the inside of the rolling machine for the work roll 1 and the back-up roll 2. The interference of each of the roll bearing housings 3 and 5 during assembly and extraction is performed, so that only a slight gap is required in a state where no rolling load is applied. The gap is preferably 0.2 to 1.0 mm. If it is less than 0.2 mm, there is a risk of interference when the work roll 1 and the back roller 2 are assembled into and withdrawn from the rolling mill. If it exceeds 1.0 mm, the rolling load is applied, even if the rolling The machine casing 30 is contracted, and the spring retainer still cannot reach the bearing seat bushings of the roll bearing seats 3 and 5, which may not be able to exert its forcing force. In either of the first embodiment and the second embodiment, the gap is set to 0.4 mm. (Example) Figs. 1 (a) and 1 of the present invention are applied to the first to seventh stations (F1 to F7) of the finishing rolling mill 4 6 of the hot rolling production line 40 shown in Fig. 7 (b) As shown in Figure 16 (a) and Figure 16 (b), the rolling condition of the paired cross rolling mill (only the bearing seat restriction device for pressing the work roll bearing seat) is rolled. A case where the cross rolling mill is rolled is shown, and the position shift amount of the work roll bearing housing is compared and evaluated. In the hot rolling production line 40 shown in FIG. 7, the component symbol 41 is a heating furnace, 42 is a sizing press, 43 is a rough rolling machine, and 44 is an end shear. , 45 is a descaling device, 47 is a cooling zone, and 48 is a winding device. Fig. 8 shows the rolling load of the fourth F 4 and the operation of becoming the cross head side 30 312 / Invention specification (Supplement) / 93-05 / 93107638 200422114 Position shift amount of the lower work roll bearing seat (conveying direction) Entrance side). In addition, the diameter of the working roll of the fourth stand of this embodiment is about 630 mm, the diameter of the back-up roll is about 1550 mm, the crossing angle is 0.02 to 1.04 degrees, and the rolling speed is 350 ~ 550mpm. Referring to FIG. 8, before the bearing block limiting device is installed, that is, in the case of applying a conventional combined cross rolling mill, during rolling, within the rolling mill housing 100, the lower working roll bearing block 104 is located at A position shift of approximately 1.2 mm occurs at the entrance side of the rolled material in the conveyance direction. In contrast, after the bearing block limiting device is provided, that is, the case of the paired cross rolling mill shown in FIG. 1 (a) and FIG. 1 (b) of the present invention is applied regardless of the rolling load. It is reported that the position deviation of the bearing seat 4 is less than 0.1 mm. It can be seen that the position shift of the Xingkun bearing block 4 can be prevented. In addition, as shown in FIG. 10, the positions of the lower work roll bearing blocks 4, 104 are embedded in the thin-lined sleeve 20, and the eddy current type distance sensor 50 is embedded. Find the distance between 50 and the lower work roll bearing block 4, 104. The output signal of the eddy current distance sensor 50 is taken into the amplifier 51, and the output of the amplifier 51 can be used to constantly monitor the activities of the work roll bearing blocks 4, 104. Furthermore, Figs. 1 (a) and 1 (b) of the present invention are applied to the first to seventh stations (F1 to F7) of the finishing rolling mill 46 of the hot rolling production line 40 shown in Fig. 7 ) Shown in the paired cross rolling mill (only the bearing block restraining device for pressing the working roll bearing block) and the paired cross 20042004114 shown in Fig. 2 (a) and Fig. 2 (b), as shown in the figure of application 16 (a), Fig. 16 (b) shows the rolling condition of the rolling mill. Compare and review the error of the differential load. Figure 9 shows the relationship of the differential load in the actual hot rolling operation of the fourth F4. In the case where the bearing block limiting device is not provided, the paired crossing shown in Fig. 16 (a) and Fig. 16 (b) is known. In addition, a differential load close to 600 kN was found. In contrast, in the case of the bearing block limiting device of the work roll and bearing block, the paired cross rolling mill white 'load error shown in Fig. 1 (a) and Fig. 1 (b) is also reduced to 4 0 0 k N. In addition, in the case where the bearing block limiting device of the Xingkun bearing block and the forced back bearing bearing limiting device are set at the same time, that is, when the paired cross rolling mill of FIG. 2 (a) of the present invention is applied, the differential load is the same. The error is reduced below. In the above, it has been explained that the present invention is applied to a hot rolling production line. For example, the present invention can also be applied to a cold rolling line rolling machine 66 shown in FIG. In Fig. 11, the component symbol 6 1 is the entrance detection 6 5 and 6 7 are the tension rolls, 6 3 is the welding machine, 6 4 is the feed breaker, and 6 9 is the reel. In addition, the present invention can also be applied to an external double-cross paired cross rolling mill and work rolls alone (industrial availability). As described above, the cross-roll rolling mill according to the present invention is a cross-roll rolling mill. In the rolling method, a simple machine roller bearing seat of the spring is forced to the roll offset direction, thereby preventing the position shift in the gap, and the snake 312 / Invention Specification (Supplement) / 93 -05/93107638, for cross rolling 0 rolling load and condition, that is, the situation of the rolling mill should be set to apply the situation 0, the difference is to force the bearing seat of the working rolling seat as shown in Figure 2 (b). The example shown is as low as 150 kN, but the finished 60, 68, and 68 discs are cut-for-roll mills with a single cross cut. And the use of this structure will work the rolling bearing housing, bending, 32 200422114 failure and other failures. In addition, in addition to the work-rolling bearing housing, the back-supporting shaft is forced by the simple mechanism of the spring to the roll offset direction to prevent the position of each bearing from being displaced in the gap, and the work-rolling-friendly The occurrence of cross angles (rolling cross angles), and the occurrence of such occurrences can be suppressed as much as possible, which can effectively prevent troubles such as meandering and bending breakage of the rolled material. In addition, as a forcible work rolling Iku bearing housing or further forcing the back mechanism, the use of springs can avoid the difficulty of installing hydraulic cylinders and hydraulic piping in a narrow space that does not interfere with rolling and roller bearing housings, so it can be cheap. And highly reliable device. In addition, by supplying lubricant to the spring retainer and the sliding part of the bearing housing bushing, the lubricant does not flow due to cooling water such as rolls, cooling water, and cooling water in the bearing housing, so that a good lubrication condition can be maintained and reduced. Expenses for repair and maintenance of spring retainer barrels. [Brief description of the drawings] Fig. 1 (a) shows the first embodiment of the cross roll rolling machine of the present invention.
