<p>PURPOSE:To improve the capacity of mill by increasing rolling reduction after biting in the pass that rolling reduction is controlled by impact torque when a plate is bitten. CONSTITUTION:In a method for rolling where a thick plate is rolled back and forth with a rolling mill, whose maximum rolling torque is regulated, at such rolling reduction as rolling torque isn't over the maximum rolling torque, after the plate is bitten at such rolling reduction as impact torque when biting isn't over the maximum rolling torque, immediately the pass that the rolling reduction is changed into larger value is executed once or more times in a pass schedule excepting the final pass.</p> |
