Description

本発明は、鋼板圧延ライン等の冷却設備に近接して設置されるサイドガイドに関するものである。   The present invention relates to a side guide installed close to a cooling facility such as a steel plate rolling line.

厚鋼板の製造において、強度や靭性の優れた鋼板を製造するために、圧延材に制御圧延（Controlled Rolling）を施すのが一般的である。しかし、制御圧延を行う場合、制御圧延開始温度が比較的低いために、その温度になるまでの温度調整に時間を要し、圧延能率の低下を招いていた。   In the production of a thick steel plate, in order to produce a steel plate having excellent strength and toughness, it is common to perform controlled rolling on the rolled material. However, when performing controlled rolling, since the controlled rolling start temperature is relatively low, it takes time to adjust the temperature until it reaches that temperature, leading to a reduction in rolling efficiency.

これに対して、近年、圧延材を通板させながらの強冷却並びに均一冷却を実現することが可能であり、それによって圧延能率を向上させることができる冷却設備が提案されている（例えば、特許文献１）。   On the other hand, in recent years, there has been proposed a cooling facility capable of realizing strong cooling and uniform cooling while letting a rolled material pass through, and thereby improving rolling efficiency (for example, patents). Reference 1).

図４は、そのような冷却設備の一例を示すものであり、通板する鋼板１の上面に向けて冷却水を供給するための一対の上ヘッダ２１、２１と、その鋼板１０の下面に向けて冷却水を供給するための下ヘッダ３１を備えている。上ヘッダ２１ａと上ヘッダ２１ｂにはそれぞれ上ノズル２２ａと上ノズル２２ｂが鋼板幅方向および搬送方向に所定の間隔で複数個取り付けられている。そして、それらの上ノズル２２ａと上ノズル２２ｂとは、それぞれから供給する上面冷却水２３ａ、２３ｂが鋼板１の搬送方向に互いに対向するように配置されている。   FIG. 4 shows an example of such a cooling facility, and a pair of upper headers 21 and 21 for supplying cooling water toward the upper surface of the steel plate 1 to be passed through, and the lower surface of the steel plate 10. And a lower header 31 for supplying cooling water. A plurality of upper nozzles 22a and upper nozzles 22b are attached to the upper header 21a and the upper header 21b at predetermined intervals in the steel plate width direction and the conveying direction, respectively. And the upper nozzle 22a and the upper nozzle 22b are arrange | positioned so that the upper surface cooling water 23a and 23b supplied from each may mutually oppose in the conveyance direction of the steel plate 1. FIG.

これによって、この冷却設備では、鋼板１の搬送方向に互いに対向するように噴射された上面冷却水２３ａ、２３ｂ自身が、鋼板１上面の滞留冷却水２４が鋼板搬送方向に移動しようとするのを堰き止める。そして、鋼板１上面の滞留冷却水２４は、鋼板１の幅端部から排水される。これによって、４ｍ３／ｍ２ｍｉｎ以上の大きな水量密度の冷却水を鋼板１上面に供給して強冷却を行う場合でも、適切に水切りが行われるので、安定した冷却領域が得られ、均一な冷却を行うことができる。
特開２００７−２０３３７０号公報 Thereby, in this cooling equipment, the upper surface cooling water 23a, 23b itself sprayed so as to face each other in the conveying direction of the steel plate 1 causes the staying cooling water 24 on the upper surface of the steel plate 1 to move in the steel plate conveying direction. Dam up. Then, the staying cooling water 24 on the upper surface of the steel plate 1 is drained from the width end portion of the steel plate 1. As a result, even when strong cooling is performed by supplying cooling water having a large water amount density of 4 m 3 / m 2 min or more to the upper surface of the steel sheet 1, draining is appropriately performed, so that a stable cooling region is obtained and uniform. Cooling can be performed.

上述したような冷却設備を厚鋼板の熱間圧延ラインに設置する場合、圧延能率を一層高めるためには、熱間圧延機（可逆式熱間圧延機）に近接して設置することが望ましい。しかし、それには以下のような問題がある。   When the above-described cooling equipment is installed in the hot rolling line for thick steel plates, it is desirable to install in the vicinity of a hot rolling mill (reversible hot rolling mill) in order to further increase the rolling efficiency. However, it has the following problems.

すなわち、可逆式熱間圧延機には鋼板のセンタリングを行うためのサイドガイドが付置されているので、冷却設備から鋼板上面に供給された上面冷却水が鋼板幅端部から排水されるのをサイドガイドが妨げてしまう。その結果、行き場を失った滞留冷却水が鋼板搬送方向に移動して冷却ムラを生じたり、新鮮な冷却水が鋼板上面に到達できなくて冷却能力の低下を招いたりして、所望の冷却効果が得られなくなってしまう。   That is, the reversible hot rolling mill is provided with a side guide for centering the steel sheet, so that the upper surface cooling water supplied from the cooling equipment to the upper surface of the steel sheet is drained from the width end of the steel sheet. The guide gets in the way. As a result, stagnant cooling water that has lost its destination moves in the direction of steel sheet conveyance, causing uneven cooling, or fresh cooling water cannot reach the upper surface of the steel sheet, leading to a decrease in cooling capacity, and the desired cooling effect. Can no longer be obtained.

本発明は、上記のような事情に鑑みてなされたものであり、鋼板上面に対して鋼板搬送方向に互いに対向するように冷却水を噴射する冷却設備を例えば熱間圧延機に近接して設置した場合に、冷却設備から鋼板上面に噴射された冷却水が円滑に排水されるようなサイドガイドを提供することを目的とするものである。   The present invention has been made in view of the circumstances as described above, and a cooling facility for injecting cooling water so as to face each other in the steel plate conveyance direction with respect to the upper surface of the steel plate is installed close to, for example, a hot rolling mill. It is an object of the present invention to provide a side guide that smoothly drains the cooling water sprayed from the cooling facility onto the upper surface of the steel plate.

上記課題を解決するために、本発明は以下の特徴を有する。   In order to solve the above problems, the present invention has the following features.

［１］鋼板上面に対して鋼板搬送方向に互いに対向するように冷却水を噴射する冷却設備が近接して設置された鋼板のサイドガイドであって、前記冷却設備から噴射される冷却水が鋼板上面に衝突する領域を挟んで鋼板搬送方向に間隔をあけて配置された第１サイドガイドおよび第２サイドガイドと、前記第１サイドガイドの上部と前記第２サイドガイドの上部を連結する連結ビームとを備えていることを特徴とするサイドガイド。   [1] A steel sheet side guide in which cooling equipment for injecting cooling water is disposed close to the upper surface of the steel sheet so as to face each other in the steel sheet conveyance direction, and the cooling water injected from the cooling equipment is a steel sheet. First and second side guides arranged at intervals in the steel plate conveyance direction across a region that collides with the upper surface, and a connection beam that connects the upper part of the first side guide and the upper part of the second side guide A side guide characterized by comprising:

［２］サイドガイドに近接して設置された前記冷却設備から噴射される冷却水の噴射方向が、鋼板搬送方向に対して鋼板幅方向外側に向けて傾斜していることを特徴とする前記［１］に記載のサイドガイド。   [2] The cooling water sprayed from the cooling equipment installed in the vicinity of the side guide is inclined toward the outside in the steel plate width direction with respect to the steel plate transport direction. 1].

［３］連結ビーム上面の前記冷却設備から噴射された冷却水が衝突する位置に、冷却水を受ける凹部が設けられていることを特徴とする前記［１］または［２］に記載のサイドガイド。   [3] The side guide according to [1] or [2], wherein a concave portion for receiving cooling water is provided at a position where the cooling water jetted from the cooling equipment collides on the upper surface of the connection beam. .

本発明においては、鋼板上面への冷却水の衝突位置で、その領域を挟んで鋼板搬送方向に所定の間隔をあけて第１サイドガイドと第２サイドガイドが配置されているので、鋼板上面に衝突した冷却水が第１サイドガイドと第２サイドガイドとの間隙から円滑に排水される。その結果、サイドガイドに冷却設備が近接して設置された場合でも、サイドガイドのセンタリング機能を損なうことなく、近接して設置された冷却設備も所望の冷却能力を得ることができるようになる。   In the present invention, since the first side guide and the second side guide are disposed at a collision position of the cooling water on the upper surface of the steel plate with a predetermined interval in the steel plate conveyance direction across the region, The impinging cooling water is smoothly drained from the gap between the first side guide and the second side guide. As a result, even when the cooling equipment is installed close to the side guide, the cooling equipment installed nearby can obtain a desired cooling capacity without impairing the centering function of the side guide.

本発明の一実施形態を図面に基づいて説明する。   An embodiment of the present invention will be described with reference to the drawings.

図１はこの実施形態を示す側面図であり、図２は同じく上面図である。   FIG. 1 is a side view showing this embodiment, and FIG. 2 is a top view of the same.

図１、図２に示すように、この実施形態においては、鋼板１のセンタリングを行うためのサイドガイド１０が熱間圧延機（図示せず）に付置されているとともに、その熱間圧延機に近接して冷却設備２０が設置されている。すなわち、冷却設備２０と同じ鋼板搬送方向位置にサイドガイド１０も位置している。なお、サイドガイド１０は鋼板１の両方の幅端部側にそれぞれ設けられているが、ここでは、一方の幅端部側のサイドガイドのみを図示している。   As shown in FIGS. 1 and 2, in this embodiment, a side guide 10 for centering the steel sheet 1 is attached to a hot rolling mill (not shown), and the hot rolling mill includes A cooling facility 20 is installed in the vicinity. That is, the side guide 10 is also located at the same steel plate conveyance direction position as the cooling facility 20. In addition, although the side guide 10 is each provided in the both width end part side of the steel plate 1, only the side guide of one width end part side is shown in figure here.

そして、この冷却設備２０は、通板する鋼板１の上面に向けて冷却水を供給するための一対の上ヘッダ２１ａ、２１ｂを備えており、上ヘッダ２１ａと上ヘッダ２１ｂにはそれぞれ鋼板幅方向および搬送方向に所定の間隔で棒状冷却水を噴射する複数個のノズル（図示せず）が取り付けられていて、上ヘッダ２１ａのノズルから噴射される上面冷却水２３ａと上ヘッダ２１ｂから噴射される上面冷却水２３ｂが鋼板搬送方向に互いに対向するようになっている。それに加えて、図２に示すように、上面冷却水２３ａ、２３ｂは、鋼板搬送方向に対して鋼板幅方向外側に向けて傾斜して噴射されている。ちなみに、互いの上ヘッダから最も遠い側（最外側）のノズルからの上面冷却水が鋼板１に衝突する位置同士に挟まれた領域が上面冷却領域ということになる。ここで、棒状冷却水とは、円形状（楕円や多角の形状も含む）のノズル噴出口から噴射される冷却水であって、ノズル噴出口から鋼板に衝突するまでの水流の断面がほぼ円形に保たれた連続性と直進性のある水流の冷却水のことをいう。   And this cooling equipment 20 is provided with a pair of upper headers 21a and 21b for supplying cooling water toward the upper surface of the steel plate 1 to be passed, and the upper header 21a and the upper header 21b are respectively in the steel plate width direction. A plurality of nozzles (not shown) for injecting rod-shaped cooling water at predetermined intervals in the transport direction are attached, and are injected from the upper surface cooling water 23a and the upper header 21b injected from the nozzles of the upper header 21a. The upper surface cooling water 23b is opposed to each other in the steel plate conveyance direction. In addition, as shown in FIG. 2, the upper surface cooling waters 23a and 23b are jetted inclining toward the outer side in the steel plate width direction with respect to the steel plate conveyance direction. By the way, the region sandwiched between the positions where the upper surface cooling water from the nozzles farthest from the upper header (outermost side) collides with the steel sheet 1 is the upper surface cooling region. Here, the rod-shaped cooling water is cooling water injected from a circular (including elliptical or polygonal) nozzle outlet, and the cross section of the water flow from the nozzle outlet to the steel plate is almost circular. It is the cooling water of the water flow with the continuity and straightness kept in the water.

なお、鋼板１０の下面には下ヘッダ３１から下面冷却水３２が供給されるようになっている。   Note that the lower surface cooling water 32 is supplied from the lower header 31 to the lower surface of the steel plate 10.

一方、サイドガイド１０は、上面冷却水２３ａ、２３ｂが鋼板１上面に衝突する位置において、鋼板搬送方向に所定の間隔をあけて配置された第１サイドガイド１１ａおよび第２サイドガイド１１ｂと、第１サイドガイド１１ａの上部と第２サイドガイド１１ｂの上部を連結して第１サイドガイド１１ａと第２サイドガイド１１ｂを一体化するための連結ビーム１２とを備えている。   On the other hand, the side guide 10 includes a first side guide 11a and a second side guide 11b arranged at predetermined intervals in the steel plate conveyance direction at positions where the upper surface cooling waters 23a and 23b collide with the upper surface of the steel plate 1. A connection beam 12 is provided for connecting the upper part of the first side guide 11a and the upper part of the second side guide 11b to integrate the first side guide 11a and the second side guide 11b.

なお、第１サイドガイド１１ａと第２サイドガイド１１ｂのそれぞれの側面にラックビーム１４が取り付けられており、この２本のラックビーム１４が一台の電動機（図示せず）に連結されていて、この電動機の作動によって第１サイドガイド１１ａと第２サイドガイド１１ｂが一体となって鋼板幅方向に移動し位置合わせが行われる。すなわち、サイドガイド１０が鋼板１のセンタリングを行う機能としては、従来のサイドガイドと変わるところはない。   A rack beam 14 is attached to each side surface of the first side guide 11a and the second side guide 11b, and the two rack beams 14 are connected to one electric motor (not shown). By the operation of the electric motor, the first side guide 11a and the second side guide 11b are integrally moved in the width direction of the steel plate and aligned. That is, the function of the side guide 10 for centering the steel plate 1 is the same as the conventional side guide.

ここで、第１サイドガイド１１ａと第２サイドガイド１１ｂは、互いに鋼板搬送方向に対向する側の端部（内側端部）は、それぞれ冷却水２３ａの噴射角度または冷却水２３ｂの噴射角度と同じ角度となっていることが好ましい。   Here, as for the 1st side guide 11a and the 2nd side guide 11b, the edge part (inner edge part) of the side which mutually opposes a steel plate conveyance direction is the same as the injection angle of the cooling water 23a, or the injection angle of the cooling water 23b, respectively. An angle is preferred.

そして、第１サイドガイド１１ａと第２サイドガイド１１ｂとの鋼板搬送方向の間隔（位置関係）については、第１サイドガイド１１ａと第２サイドガイド１１ｂが上面冷却領域を挟むように配置されており、具体的には、最外側の上面冷却水２３ａと第１サイドガイド１１ａの内側端部との間隙δａおよび最外側の上面冷却水２３ｂと第２サイドガイド１１ｂの内側端部との間隙δｂが、それぞれ５０ｍｍ〜２００ｍｍとなるようになっている。   And about the space | interval (positional relationship) of the steel plate conveyance direction of the 1st side guide 11a and the 2nd side guide 11b, it arrange | positions so that the 1st side guide 11a and the 2nd side guide 11b may pinch | interpose an upper surface cooling area | region. Specifically, there is a gap δa between the outermost upper surface cooling water 23a and the inner end of the first side guide 11a and a gap δb between the outermost upper surface cooling water 23b and the inner end of the second side guide 11b. , 50 mm to 200 mm, respectively.

また、連結ビーム１２の上面には上面冷却水２３ａ、２３ｂが衝突するので、連結ビーム１２上面のそれぞれの冷却水衝突位置に、衝突した上面冷却水２３ａ、２３ｂが上方に跳ね返って飛散しないように、上面冷却水２３ａ、２３ｂを受ける凹部１３が設けられている。   Further, since the upper surface cooling waters 23a and 23b collide with the upper surface of the coupling beam 12, the collided upper surface cooling waters 23a and 23b do not splash and splash at the respective cooling water collision positions on the upper surface of the coupling beam 12. A recess 13 for receiving the upper surface cooling water 23a, 23b is provided.

図３は、凹部１３の形状の一例を示すものであり、例えば上面冷却水２３ａ、２３ｂの噴射角度が４５°、噴射幅が１００ｍｍに対して、凹部１３は曲率半径が１４５ｍｍの曲面となっている。   FIG. 3 shows an example of the shape of the recess 13, for example, the upper surface cooling water 23 a, 23 b has an injection angle of 45 °, an injection width of 100 mm, and the recess 13 has a curved surface with a curvature radius of 145 mm. Yes.

これによって、上記のように構成されたサイドガイド１０を用いると、上面冷却水２３ａ、２３ｂが、鋼板１上面に衝突した後、第１サイドガイド１１ａと第２サイドガイド１１ｂとの間に設けられた間隙から円滑に排水されるようになる。すなわち、これによって、上面冷却水２３ａ、２３ｂの適切な排水ルート２６が確保されたことになる。しかも、上面冷却水２３ａ、２３ｂが鋼板搬送方向に対して鋼板幅方向外側に向けて傾斜して噴射されているので、より一層円滑に排水されることになる。   Accordingly, when the side guide 10 configured as described above is used, the upper surface cooling waters 23a and 23b are provided between the first side guide 11a and the second side guide 11b after colliding with the upper surface of the steel plate 1. Drains smoothly from the gap. That is, as a result, an appropriate drainage route 26 for the upper surface cooling waters 23a and 23b is secured. Moreover, since the upper surface cooling waters 23a and 23b are jetted inclining toward the outer side in the steel plate width direction with respect to the steel plate conveyance direction, the water is drained more smoothly.

また、連結ビーム１２上面の凹部１３に衝突した上面冷却水２３ａ、２３ｂは、上方に跳ね返ることなく、しかも、鋼板幅方向外側に向けて傾斜して噴射されていることも加わって、排水ルート２６を経由して円滑に排水される。   Further, the upper surface cooling waters 23a and 23b that have collided with the recesses 13 on the upper surface of the connecting beam 12 do not bounce upward, and are also injected obliquely toward the outer side in the steel plate width direction. It is drained smoothly via

なお、上面冷却水２３ａ、２３ｂが鋼板搬送方向に平行に噴射されている場合には、凹部１３に衝突した上面冷却水２３ａ、２３ｂが鋼板幅方向外側に向けて流れやすくなるように、凹部１３に鋼板幅方向外側に向けた下り勾配を持たしておくことがよい。   In addition, when the upper surface cooling waters 23a and 23b are sprayed in parallel to the steel plate conveyance direction, the upper surface cooling waters 23a and 23b that collide with the concave portion 13 are easy to flow toward the outer side in the steel plate width direction. It is preferable to have a downward slope toward the outer side in the steel plate width direction.

このようにして、この実施形態においては、例えば４ｍ３／ｍ２ｍｉｎ以上の大きな水量密度の上面冷却水２３ａ、２３ｂを鋼板１上面に向けて供給した場合であっても、供給された上面冷却水２３ａ、２３ｂが排水ルート２５あるいは排水ルート２６を経由して円滑に排水される。その結果、所望の冷却効果を得ることができるようになり、圧延能率を一層向上させることが可能になる。 Thus, in this embodiment, even when the upper surface cooling waters 23a and 23b having a large water amount density of, for example, 4 m 3 / m 2 min or more are supplied toward the upper surface of the steel sheet 1, the supplied upper surface cooling is performed. The water 23a, 23b is smoothly drained through the drainage route 25 or the drainage route 26. As a result, a desired cooling effect can be obtained, and the rolling efficiency can be further improved.

なお、本実施形態では、冷却設備が近接して設置された熱間圧延機に付置されているサイドガイドについて説明したが、本発明はこれに限られるものではなく、冷却設備と同じ鋼板搬送方向位置に設置されているサイドガイドであれば、同様に適用することができる。   In addition, although this embodiment demonstrated the side guide attached to the hot rolling mill with which the cooling equipment was installed in proximity, the present invention is not limited to this, and the same steel plate conveyance direction as the cooling equipment. A side guide installed at a position can be similarly applied.

また、本実施形態では、冷却設備から噴射される冷却水が棒状冷却水の場合について説明したが、本発明はこれに限られるものではなく、例えば、冷却設備から噴射される冷却水が鋼板幅方向に拡がりを持つ場合などにも適用することができる。   Moreover, although this embodiment demonstrated the case where the cooling water injected from a cooling facility was a rod-shaped cooling water, this invention is not limited to this, For example, the cooling water injected from a cooling facility is steel plate width | variety. It can also be applied to the case where there is a spread in the direction.
