Abstract
PURPOSE:To prevent a sheet from causing meandering during a rolling by obtaining the relation between the material strength of the sheet and the difference in tension of the sheet between an input side and an output side of a rolling mill when a rolled stock is cold-worked. CONSTITUTION:A rolled stock is cold-rolled by a bridle roll 1 on the inlet side of the rolling mill 4 and a bridle roll 6 on its outlet side giving a tension to the rolled stock. In this case, the difference values in tension between respective rolled stocks is inputted by tensionmeters 11, 13 into a controller 15. The number of rotations of the bridle rolls 1, 6 driven by motors 2, 7 in this manner is adjusted and controlled. At this time, the boundary curve for occurrence of meandering is obtained regarding the difference of tension and the tension is set so that it comes under the boundary curve for occurrence of hunting according to the strength of the rolled stock which has been obtained in advance. In this way, the occurrence of meandering during the rolling is prevented and the quality is improved.
