うにしている。Detailed Description of the Invention The present invention relates to a rolling method in which a metal plate material is JJ rolled in a rolling mill and the rolled material is wound up in a winder. The purpose of this method is to obtain a rolled material with a shape. Conventionally, in order to manufacture a 1 m plate of aluminum or other gold, the raw metal plate material was rolled in a rolling mill, and the rolled material was wound up. I try to wind it up one by one on the machine.

が幅方向において可及的に均一となるようにしくいた。In order to roll 1q of flat-shaped rolled material, measure the shape of the rolled material at the exit side of the rolling mill, and adjust the bending of the rolling rolls and the temperature of rolling [1-l] according to the tJ side value. The distribution was controlled so that the shape of the rolled material delivered to the exit side was as uniform as possible in the width direction.

の差も犬ぎくなり、前記伸長用も人きくなっていた。However, even if a flat rolled +A is obtained continuously from the start to the end of rolling by the method described above, such a rolled material is normally wound and the rolled material is not rolled after rolling. When unwinding, the rolled material, which should have a flat shape,
Partially stretched in the length direction1. : There was a problem with rolling +J. This is a phenomenon that occurs as a result of the winding tension applied to the thick part of the plate 19 being larger than the tension horn of the thin part of the plate 19 in the cross-sectional profile, resulting in partial elongation. As the diameter of the winding coil increases, tubes with different plate thicknesses are overlapped, and the difference in winding tension becomes narrower.

にし、前記従来の問題点を解決したものである。This invention was made in view of the above-mentioned problems, and the part of the rolled H that is not stretched after winding, that is, the part where the plate thickness is thin in the cross-sectional profile and the winding tension is small, is pre-lengthened at the time of rolling. In order to elongate in the transverse direction, this part is rolled with a large elongation, and this rolled part is wound up on a winder. By combining the elongated part with the part that is elongated after winding, and as a result, a rolled material having a flange shape is obtained when it is unwound from the winder, thereby solving the problems of the conventional method. It is resolved.

If the fill P is a metal plate +41a J: sea urchin, if the center part is thicker than the edge part in the width direction, the unwound rolled material 4 has a part in the center part in the length direction as shown by S in the figure. On the other hand, if the cross-sectional profile P is a metal plate (like 41C, where the center is thinner than the edges in the width direction,
As shown by SC in the figure, the edge of the rolled material 4 is partially elongated in the length direction 1j. The above partial elongation increases as the diameter R of the winding coils 3a and 311.3G increases.

And the roll coolant 1 to the controller 14 are operated. The comparison results shown in Fig. 3 show that the edges of the rolled material 4 are more elongated than the target shape]), and the center part is more elongated than the target shape.
P J: Elongation - (C, in roll bending control, the central parts of the opposing rolling rolls 5.5 are kept close to each other, and the ends are kept isolated from each other. Temperature distribution of the rolls. In the control of the rolling process, the spraying of coolant 1 to the center of the rolling roll 5.5 is reduced, the diameter of the roll is increased due to the temperature rise of the C1 line, and the spraying of the coolant 1 to the end of the roll is increased. Increase the 1n fog Fn of 1~
Therefore, the roll diameter is reduced due to the temperature drop in the wire portion. It should be noted that it is possible to bring the shape of the rolled material 4 closer to the target shape B by controlling only one of the roll bending control and temperature distribution control described in -F.
