Abstract

PURPOSE: To improve the plane shape after finishing by performing roll bending in accordance with the forecast plane shape after finishing of a material to be rolled.
CONSTITUTION: on the way of broadside rolling, a rolling mill provided with a roll bending function is used, and convex crowns are given to a material 2 to be rolled by performing roll bending with work rolls 8, 8'. Further the material 2 is then rotated 90° and is subjected to thickness increasing rolling to remove the convex crowns. To perform the roll bending, the hydraulic cylinders provided between work roll chocks are operated to bend the work rolls to convex crowns. By performing the rolling of giving convex crowns to the material to be rolled on the way of broadside rolling in this way, the flow of the material is generated in the front and rear end parts in the rolling direction, and the projecting parts at the corners are made roughly uniform in the width direction of the material to be rolled. Hence, if the next thickness increasing rolling is carried out, the crowns of the material to be rolled are removed, and a plane shape is made close to a rectangular shape.
