Abstract

PURPOSE: To perform the rolling work for manufacturing the sheet being flat along entire breadth, by detecting the sheet shape on the delivery side, by operating the cirrective amount for the shape, and by independently controlling respective screw down device and roll bender on the driving side and on the operating side, in the rolling mill for the sheet material or the like.
CONSTITUTION: The shape of the rolled material 5 is detected by the shape detector 10 installed on the delivery side of the rolling mill constituted of backup rolls 3, 4, and work rolls 1, 2, for rolling the sheet material 5; the shape signals for the left side and the right side are inputted to the operators 16, 17, which operate the shape vector whose components are the inclinations of the rate of change in the shape on the left side and the right side in the direction of breadth; the rolling condition setter 18 and the computer 19 compute the corrector vector owing to the benders; this vector is inputted to the computer 15; four corrective values for the driving side and the operating side screw down devices 8, 9, and the driving side and the operating side roll benders 6, 7, are computed so as to make zero the resultant vector of above two shape vectors; and the screw down devices 8, 9, and the roll benders 6, 7, are respectively independently controlled through the command units 13, 14, 11, 12; the controller is thus constituted and the accuracy of thickness in the direction of breadth of the rolled sheet is improved.
