  • Control Of Metal Rolling (AREA)

Abstract

PURPOSE: To simutaneously control the shape and thickness of a rolled material, and to quicken and stabilize the control function of a rolling mill, by determining the roll bending force, the position of a reducing screw, and the interstand tension to be given to the rolled material, from a prescribed numerical equation according to the corrective target values for the shape and thickness of said rolling material.
CONSTITUTION: A computer 8 determines the correction value ΔF for the roll bending force, the correction value ΔS for the position of a reducing screw, and the correction value Δσ for the interstand tension, by computing equation I according to the corrective target values for the shape and thickness of a rolled material. In equation I, Δh* is the corrective target value for the thickness, Δew* is the corrective target value for the edge wave, and Δcb* is the corrective target value for the center buckle, in which the latter two characteristics are the factors for correcting the shape of the rolled material. The characters β11, β12, β13 are the parameters for determining the correction value for the roll bending force, and β31, β32, β33 are the parameters for determining the correction value for the position of the reducing screw; each of these parameters is a modulus to be determined by the quality and size of the rolled material and the capacity of the rolling mill. Accordingly, the correction values for the manipulated variables in controlling the thickness and shape of the rolled material are determined so as to reduce their mutual interferential disturbance to a minimum.
