<p><P>PROBLEM TO BE SOLVED: To provide a plate shape control method by a split backup roll type plate rolling mill by which the dimensions and the shape of a plate is controlled in high accuracy and stable rolling operation is realized. <P>SOLUTION: In the plate shape control method, the plate shape when a plate is rolled is estimated in a split backup roll type plate rolling mill 8 based on the loads and the positions of reduction of split backup rolls 21-27, and 51-57 measured when the plate is rolled, and a plate shape controller is controlled so as to obtain the target plate shape based on the result of the estimation. The positions of both edges in the width direction of a work S to be rolled under the rolling are measured or estimated, and the positions of reduction of the split backup rolls 21-27, and 51-57 are controlled based on the measured values or the estimated values. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
