Abstract

PURPOSE: To improve the quality of a rolled stock by operating to minimize mutual interference of amount of correction of shape and plate thickness according to the target amount of correction of shape and plate thickness of a rolled stock and thereby changing roll bender force, rolling position and peripheral speed ratio of working roll simultaneously.
CONSTITUTION: Output of a shape detector 3 is converted to end elongation (ew) and intermediate elongation (cd) by a shape recognizing device 5, and target amount of shape correction Δew*, Δcb* is calculated. The amount of operation that minimizes the interference of change of amount of operation of the shape and thickness of the plate to each other is operated by an arithmetic device 8. These are outputted as amount of change of bending force ΔF2, amount of change of screw down position Δs and amount of change of roll periphery speed ratio Δk to respective controlling device 9, 11, 12 to control the rolling mill.
