<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a rolled stock and a device for clamping a roll chock for obtaining the rolled stock excellent in dimensions and a shape by reversing rolling. <P>SOLUTION: The operation of the device for clamping the roll chock is started linking with the operation starting signal of a bender of a reversing rolling mill 1, and the chock is clamped by a large force of constraint until a preset time lapses. Next, the chock is clamped by a small force of constraint until a preset time 2 lapses after a sheet is bitten and the large force of constraint is set in steady rolling. <P>COPYRIGHT: (C)2012,JPO&INPIT |
