<p><P>PROBLEM TO BE SOLVED: To provide a method of rolling a steel strip by which stable control of meandering is performed over the entire length of rolling from the steady part of the rolling to the tail end. <P>SOLUTION: When performing levelling control at the i-th stand in such a manner that right and left difference tension which is detected with a tension measuring roll between optional i-th stand and (i+1)th stand is zero or not larger than the target value, the levelling control is started at earlier timing as stands on the downstream side and also, at the i-th stand which starts the levelling control, after the right and left difference tension between the i-th stand and the (i+1)th stand is zero or not larger than the target value, the levelling control at the (i-1)th stand on the upstream side is started. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
