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.
