Abstract

PURPOSE: To keep the interstand balance and to improve the shape of the sheet, by uniformly correcting the fundamental alteration of the roll gap in individual upstream stand according to the error of alteration of the roll gap in the final stand.
CONSTITUTION: The alteration of the roll gap in individual stand on the upstream side of the final stand is determined as follows. That is, the errors of alterations of two roll gaps in the final stand and the error of alteration of the roll gap in this time are obtained. And the alteration of the roll gap of individual stand to be set for the rolling pass in this time is obtained. Accordingly, the roll gap of each stand on upstream side is obtained by adding the alteration to the roll gap in the former rolling pass. According to this method, the alteration of roll gap of each stand fluctuates uniformly and the interstand balance can be kept. By thus keeping the balance, the shape of sheet is guaranteed.
