IPC: B21B37/38
Filed: 1987-01-16
Abstract: PURPOSE:To accurately control a shape at the time of rolling the vicinity of a connected part of a steel plate by changing a correcting gain of a feed back shape control as the function of a shift value of intermediate rolls and controlling the bending force of the rolls. CONSTITUTION:A cold rolling mill 5 is equipped with a work roll bender 11, intermediate roll bender 13 and an intermediate roll shift 14. As these values of the intermediate roll shifts and the roll bender force are mutually related to affect the shape, so the relation is obtained previously by a real machine. For example, when the value of the intermediate rolls are enlarged, the work roll bender force is controlled to be small, conversely the bender force of the intermediate roll is controlled to be large. In this way, at the time of rolling the vicinity of the connecting parts wherein the thicknesses and widths of the plate are different, the feedback control correcting value of the shape is changed as a function of the intermediate roll shifting value to control the bender force and to control with high accuracy.
