<p><P>PROBLEM TO BE SOLVED: To perform a strip width control stably with high accuracy under a reduced calculation load. <P>SOLUTION: In the strip width control method of a continuous rolling mill 1, a plurality of strip width estimation models and an evaluation function are set. An entry tension on the stand B at each estimation time is calculated so as to minimize the evaluation function, and it is determined whether a control calculation at the calculation check time is completed or not. When the control calculation is not completed, the entry tension which is already calculated in the last control period and corresponds to the present control period is applied to the rolling stand B. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
