ム１４に固着されている。Generally, a rotary continuous casting device using a rotary mold is
As shown in the figure, a rotary mold is formed from a casting wheel 1 having grooves 2 on its curved surface, and an endless belt 6 that rotates while being supported by guide rollers 3, 4, and 5 and closes part of the groove 2 in the circumferential direction. molten steel is injected into the mold from the arrow A position, and the unloading roller 1
Then, the slab 9 is continuously transferred to the next process via the pinch roller 8.
The belt 6 that comes into contact with the molten steel is cooled by a belt cooling device 10 arranged on the side of the belt 6 opposite to the casting wheel 1.
It is fixed to a frame 14 which supports the guide rollers 3 and 4 through the cylinders 1 and 12, and the guide roller 5 through the cylinder 13, respectively.
各アーム１１．１２は、鋳造輪１の熱膨張あるいは溝２
の内部損傷時の改削に対応するため、軸１５，１６を中
心として回転できるように構成されている。Each arm 11.12 corresponds to the thermal expansion or groove 2 of the casting wheel 1.
In order to cope with modification in the event of internal damage, the shafts are configured to be rotatable around shafts 15 and 16.

２等から構成され、ブラケット２２とスプリング１９の
一端はフレーム１４に固着されて〜・る。In the rotary continuous casting apparatus configured as described above, the conventional belt cooling device has a cooling plate 18 that has a water jacket 17 inside and discharges cooling fluid toward the surface of the belt 6, as shown in FIG. , a spring 19 that presses the cooling plate 18 against the belt 6, and a pin 2 that supports the weight of the cooling plate 18.
0. Bracket 2 having a long hole 21 through which the pin 20 passes
The bracket 22 and one end of the spring 19 are fixed to the frame 14.
以上の構成において、冷却流体は冷却板１８とベルト６
との間隙を流出して外部に排出される。In the above configuration, the cooling fluid flows between the cooling plate 18 and the belt 6.
It flows out through the gap between the two and is discharged to the outside.
このため、冷却板１８は冷却流体とスプリング１９によ
る押圧力とがバランスする位置までベルト６表面から浮
上することになる。Therefore, the cooling plate 18 floats up from the surface of the belt 6 to a position where the cooling fluid and the pressing force by the spring 19 are balanced.
そして、鋳造輪１が鋳造中に熱膨張しても、この位置で
冷却板１８がベルト６から浮上するため、ベルト６と冷
却板１８とは接触しないと考えられていた。It was thought that even if the casting wheel 1 thermally expanded during casting, the belt 6 and the cooling plate 18 would not come into contact because the cooling plate 18 would float above the belt 6 at this position.
しかしながら、実際に操業してみると、スプリング１９
の押圧力のばら付き、冷却板１８の自重を支える支点で
の摩擦力のばら付きおよび重力の影響等により、冷却板
１８を全面均一にベルト６から浮上させることが困難で
あることが判った。However, when actually operating, the spring 19
It has been found that it is difficult to float the cooling plate 18 uniformly over the entire surface from the belt 6 due to variations in the pressing force of the cooling plate 18, variations in the frictional force at the fulcrum supporting the weight of the cooling plate 18, and the influence of gravity. .
この結果、冷却板１８とベルト６との間隙が不均−とな
り、冷却能力が流速と密接な関係にあることから、鋳片
も不均一に冷却され、製品品質の劣化をもたらすという
難点があった。As a result, the gap between the cooling plate 18 and the belt 6 becomes uneven, and since the cooling capacity is closely related to the flow velocity, the slab is also cooled unevenly, resulting in a problem of deterioration of product quality. Ta.
本発明はかかる現況に鑑み創案されたもので、その目的
とするところは、冷却板とベルトとの間隙を均一に保つ
ことができ、これによってベルトを均一に冷却すること
ができる回転式連続鋳造装置を提供するにある。The present invention was devised in view of the current situation, and its purpose is to use a rotary continuous casting method that can maintain a uniform gap between the cooling plate and the belt, thereby cooling the belt uniformly. We are here to provide you with the equipment.
本発明は、冷却板とベルトとの間隙を冷却水圧で決定す

の間隙を機械的に決定し、しかも鋳造輪の熱膨張に追従
できるように、冷却装置の両端をガイドローラ軸で支持
するように構成したものである。The present invention has confirmed in actual operation that the method of determining the gap between the cooling plate and the belt using cooling water pressure is not practical, and has developed a method that can mechanically determine this gap and follow the thermal expansion of the casting wheel. , both ends of the cooling device are supported by guide roller shafts.
以下本発明を第３図に示す一実施例に基づいて説明する
。The present invention will be explained below based on an embodiment shown in FIG.
なお、第２図に示す従来のものと同一または同等部材は
同一符号で示し、重複を避けるためその説明は省略する
。Incidentally, members that are the same or equivalent to those of the conventional one shown in FIG. 2 are designated by the same reference numerals, and their explanations will be omitted to avoid duplication.
第３図において１８は冷却板であり、この冷却板１８の
背面側には、先端にねじ加工が施された。In FIG. 3, 18 is a cooling plate, and the tip of the back side of this cooling plate 18 is threaded.
筒状の突出部２３が４個設けられている。Four cylindrical protrusions 23 are provided.
そして、この突出部２３は、ブラケット２４に設けであ
る開口部２５に鋳造輪１の中心方向に摺動可能に嵌合さ
れ、ナツト２６により冷却板１８のベルト６側への動き
が規制されて〜・る。The protrusion 23 is fitted into an opening 25 provided in the bracket 24 so as to be slidable toward the center of the casting wheel 1, and a nut 26 restricts the movement of the cooling plate 18 toward the belt 6. ~・ru.
突出部２３の内部には、冷却板１８をベルト６側に付勢
するスプリング２７が挿嵌配置され、このスプリング２
Ｔの押圧力は、冷却流体の圧力では冷却板１８が移動し
ないような大きな値に設定されている。A spring 27 that urges the cooling plate 18 toward the belt 6 is fitted inside the protrusion 23 .
The pressing force of T is set to a large value such that the cooling plate 18 does not move under the pressure of the cooling fluid.
ブラケット２４の一端は、ガイドローラ３の軸２８の両
端に回動自在に取付けられ、また他端は、摺動子２９を
介してガイドローラ４の軸３０の両端に回動自在かつ軸
２８と軸３０との距離が変わってもこれに追従できるよ
う摺動自在に取付けら１れている。One end of the bracket 24 is rotatably attached to both ends of the shaft 28 of the guide roller 3, and the other end is rotatably attached to both ends of the shaft 30 of the guide roller 4 via a slider 29. It is mounted slidably so that it can follow changes in distance from the shaft 30.
摺動子２９の摺動力向は、ガイドローラ４の中心と鋳造
輪１の中心とを結ぶ直線に対しこれに直交する方向であ
り、軸２８と軸３０との距離が変化した場合の冷却板１
８とベルト６との間隙変化が最少になるように構成され
て〜・る。The direction of the sliding force of the slider 29 is perpendicular to the straight line connecting the center of the guide roller 4 and the center of the casting wheel 1. 1
8 and the belt 6 is configured such that the change in the gap between the belt 6 and the belt 8 is minimized.

張による間隙変化は、最大箇所でも設定間隙の１割以下
であり実用上無視できる。This change means that the outer curvature of the casting wheel 1 changes and the cooling plate 1 changes.
This refers to the change in the gap in the longitudinal direction of the cooling plate 18 that occurs when there is a difference between the inner curvature of Yes, it can be ignored in practical terms.
以上の構成において、熱膨張により鋳造輪１の径が拡大
すると、ガイドローラ３，４の間隔が変化し、これに伴
な〜・ブラケット２４も移動する。In the above configuration, when the diameter of the casting ring 1 increases due to thermal expansion, the distance between the guide rollers 3 and 4 changes, and the bracket 24 also moves accordingly.
これにより、冷却板１８の位置が変化し冷却板１８とベ
ルト６との間隙はほぼ一定に保持される。As a result, the position of the cooling plate 18 changes, and the gap between the cooling plate 18 and the belt 6 is maintained substantially constant.

間隙を再調整する。In addition, if the outer peripheral surface of the cast wheel 1 is modified, the cooling plate 1
Since the gap between the cooling plate 18 and the belt 6 is wide, the gap between the cooling plate 18 and the belt 6 is readjusted by operating the nut 26 according to the amount of modification.
以上説明したように本実施例によれば、鋳造輪の熱膨張
に対して冷却板の位置が変化し、この間隙を実用上問題
とならない範囲に保つことができるので、鋳片が均一に
冷却され製品品質の劣化を防止することができる。As explained above, according to this embodiment, the position of the cooling plate changes in response to the thermal expansion of the casting ring, and this gap can be kept within a range that does not pose a practical problem, so that the slab is cooled uniformly. This can prevent deterioration of product quality.
冑、本実施例では一端だけを摺動自在にしたが、本発明
