<p>PURPOSE:To prevent the generation of a shape faulty by correcting the gain of a control system of one side to control only roll bender force of this side when either work roll bender force or an intermeciate roll bender force is on the operating limit. CONSTITUTION:The work roll bender 11, intermediate roll bender 13 and intermediate roll shift 14 are provided to a cold rolling mill 5 as a shape control means. Then, when one of the work roll bender force and the intermediate roll bender force is the operating limit, one of the bender forces is kept as it is, the gain of the control system of the other roll bender force is corrected to correct the plate shape to be a object shape by controlling only the other roll bender force. In this way, even if one of the bender force is the operation limit or over, the generation of the shape faulty is prevented by controlling the bender force of the other side.</p> |
