<p><P>PROBLEM TO BE SOLVED: To provide a method of controlling the meandering of the tail end in hot rolling by which difference load disturbance caused by primary factors other than the meandering at the most tail end is removed without using a meandering detecting device. <P>SOLUTION: In the method of controlling the meandering of the tail end in the hot rolling, by which the control of the meandering is performed on the basis of the difference load between the operation side and the drive side of the rolling mill of each stand, feedforward control by which the controlled variable of the meandering in the front stand is added to the controlled variable of meandering in that stand at a certain rate, is performed. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
