ABSTRACT:
A device for determining a setting value of a shape operating amount in a continuous rolling mill having shape controlling means therein. As rolling conditions such as thicknesses, width, rolling loads, roll crown, incoming crown, and incoming flatness are inputted, shape operating amounts are set to attain a constant crown ratio corresponding to a product target crown as early as possible in the first n-1 stands or passes such that as many as possible of the final stands or passes maintain the constant crown ratio to improve the final product flatness.
