<p><P>PROBLEM TO BE SOLVED: To provide a method for controlling the zigzag motion of a steel strip in continuous hot rolling which can excellently carry out the control of the zigzag motion based on deviation between load differences on the driving side and the operating side of a cross roll mill, and the parallelism stiffness value of a rolling mill in the continuous hot rolling of the steel strip including rolling at the cross roll mill, and as a result, can appropriately prevent the generation of the break back of the tail end of the steel strip. <P>SOLUTION: In the case that a present stand is composed of the cross roll mill, the parallelism stiffness of the stand is changed according to the cross angle of the cross roll mill. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
