。In conventional rolling in the strip width direction, the strip width dimension is not clearly determined, which has a large impact on the determination of the strip thickness reduction rate and amount in the next rolling stage, horizontal rolling. There was a drawback that rolling was difficult to perform.

た。1. For the vertical rolls that roll the strip in the width direction, a sloped edger roll is used to prevent the rolled material from twisting. Therefore, the strip width has an inclination in the thickness direction. It becomes a cross section. Therefore, the plate thickness cannot be easily determined based only on the reference opening degree, which causes an error in the plate width dimension. In addition, in order to prevent scratches on the surface of the material to be rolled, the material to be rolled is usually placed on table rolls with legs spread apart. - The height of rolling when rolling with a sill, that is, the position of the pass line is different. As described above, in the conventional rolling control method, when the position of the pass line changes, it is not possible to accurately determine the width of the sheet, resulting in an error in the width after rolling.
