Abstract

PURPOSE: To let shape correction be accomplished relatively readily and rationally by detecting the shapes of the rolled material, once making them to a simple shape and controlling the same to the target shape through controlling after this.
CONSTITUTION: In the case of reverse cold mills, the target shape SR is given by 6. The target shape is determined by matching of the input of the target shape selecting element 7 and the shape feedback signal 12 being another input. In the young pass, the shape FB signal SF is made the target signal itself in the case of the simple shape. In the case of composite elongations, any of (one side elongation), (middle elongation) and (edge elongation) is made the target shape of that time depending upon each case and the actual target shape SRA 8 is outputted. From the deviation of these SRA and SF, a control device 8 determines the operation and control quantities. The actual shape S 13 is obtained through rolling mills 10 and rolling phenomena and the shape FB signal 12 is obtained through a shape detector 11.
