IPC: B21B37/62
Filed: 1987-02-09
Abstract: PURPOSE:To accurately control sheet thickness by finding a changing amount of a roll gap correction amount based on a thickness deviation on every calculation cycle, a mill constant, and a plasticity coefficient of a rolled stock and correcting a roll gap based on the changing amount. CONSTITUTION:An inlet side sheet thickness of a rolled stock 1 on every calculation cycle is measured by an X ray thickness meter 18, is inputted to a sampler 20, and is compared with the preceding value in a memory circuit 22 to find a sheet thickness variation (deviation) DELTAHi. A mill constant Ki and a plasticity coefficient Mi of the stock are obtained by a computing element 24 and a changing amount DELTAS of a roll gap correction amount is obtained by a computing element 26 based on the above Ki and Mi. A roll gap correction amount SOS(i) is found by adding the changing amount DELTAS to the preceding correction amount and a roll gap is corrected through a transfer circuit 30 and a hydraulic draft control circuit 32. A sheet thickness is accurately controlled because a roll gap correction amount is found based on a thickness deviation having a temporal identity for both mill constant and plasticity coefficient.
