SHAPE CONTROL ROLLING METHOD OF ROLLING STOCK

PURPOSE: To realize the full automatic rolling with excellent yield by achieving the returning to the automatic shape control set value, and achieving the regular rolling immediately after completing the rolling of optimum shape correction to an edge clip part to reduce the defective shapes of the edge clip part. CONSTITUTION: The relationship between factors such as the rolling load, thickness and the width to affect the plate shape is preliminarily stored in a shape control initial setting arithmetic unit 5, and the set values of the optimum rolling conditions are given to an intermediate roll bending equipment 3a and a work roll bending equipment 3b to achieve the regular rolling. The positions in the longitudinal direction and the width direction of an edge clip part are received by a tracking information input device 7, and the optimum shape correction value is calculated and given to the edge clip part by a shape control arithmetic unit 8. A shape correcting equipment 9 is operated at the timing of X seconds prior to passing of the edge clip part through the rolling mill, and the rolling is achieved by increasing the bender pressure. Full automatic rolling can be achieved by being returned to the regular rolling after the rolling of the edge clip part is completed.
