<p><P>PROBLEM TO BE SOLVED: To surely suppress a change in the shape of a rolled stock without installing a sheet profile meter between stands even when the thickness of the rolled stock on the outlet side changes. <P>SOLUTION: When controlling the sheet shape on the outlet side of a stand by interlocking with load is controlled by manipulating a bender 10 for an arbitrary stand (i) of a rolling mill in which a plurality of rolling stands are continuously provided, a change in sheet crown ratio when starting the control is set to the target value and the sheet crown deviation after starting the control is calculated by using actual sheet crown on the outlet side which is calculated from the results ( gage meter thickness, rolling load, bender pressure and cross angle ) of rolling in an arithmetic unit 12 for commanding the bender pressure, the calculated sheet crown deviation is compensated by the bender pressure and the change in the sheet crown ratio is kept constant. <P>COPYRIGHT: (C)2005,JPO&NCIPI</p> |
