Abstract

PURPOSE: To contrive the improvement of accuracy of thickness in the direction of breadth of the sheet, by detecting the shape of rolled sheet on the delivery side of the rolling mill provided with rolls movable in the axial direction, by calculating the corrective value for shape, and by controlling the mover for upper and lower rolls in the axial direction, and roll benders on the driving side and operating side.
CONSTITUTION: The shape of rolled sheet on the delivery side of the rolling mill provided with intermediate rolls 3, 4, movable in the axial direction by movers 9, 10, being interposed between the work rolls 1, 2, for rolling the material 21 and the backup rolls 5, 6, is detected by the detector 15 whose signals for the left side and the right side are inputted to operators 16, 17, which then make respective shape vector resulted from taking the inclination of the rate of shape change as the components; this vector together with the corrector vector for the left and the right roll benders and upper and lower rolls obtained from the rolling condition setter 19 and the computer 20, are inputted to the computer 18 which then computes four corrective values for upper and lower rolls' axial movers 13, 14, and the driving side and operating side roll benders 7, 8, so as to make zero the resultant vector of above two shape vectors; and these four parts are respectively independently controlled through the command units 13, 14, 11, 12; thus the controller is constituted.
