Abstract

PURPOSE: To let rolling to good shapes be accomplished by providing rolling pressure detectors and shape detectors and controlling screw-down devices, roll benders and roll shifters.
CONSTITUTION: A closed loop control unit 20 detects the rolling forces at both ends of rolls with detectors 121, 122 and controls the level and roll bending forces of screw-down positions. A closed loop control unit 21 is inputted with various rolling condition quantities, selects at least two factors out of roll movement positions, roll bending forces and screw-down positions and determines and controls the optimum correction quantities. A non-interference control uunit 19 regulates the speed of an un-coiler so that thicknesses do not change, with respect to the output values of the screw-down position correcting quantities of an open loop control unit 20 and a closed loop control unit 21 and regulates roll bending forces so tat shapes do not change with respect to the screw-down position correcting quanties of an automatic thickness control unit 18. A roll temperature control unit 22 detects the rotating speed of the coiler and controls the temperature of the rolls constant from the volume of cooling water.
