Abstract
PURPOSE: To prevent the generation of camber while the rolling work, by properly setting the reducing position of individual work side (WS) and drive side (DS) before starting thr rolling pass, and besides, by correcting the reducing position of one side while the rolling is preceeding.
CONSTITUTION: When the (i)th pass comes to end, the computer-controller 17 receives the signals for the sum FSA and the difference FDA of actually measured rolling load on both sides, the signals SWS, SDS, for actually measured reducing positions on both sides, and the settled sheet thickness difference C, and delivers the signal SP for setting the reducing position in the next pass on purpose to set the reference position of reducing in the next pass. Then, the brake signal B is inputted to the DS-reducing controller 15, so as to fix the screw down motor 10 for DS, and the signal for the change γS = SWSP - SDSP in the reducing is inputted to the WS-reducing controller 14; hereby, the screw down motor 11 corrects and sets the reducing position of WS. The computer-controller 17 inputs signals of the reciprocal of the mill constants MDS, MWS, for both sides, and the corrective quantity CO, into the computer-controller 16. According to this method, the generation of camber in the next pass is prevented.
