Abstract
PURPOSE:To automatically prevent the generation of a camber and to improve working efficiency and quality by detecting the camber of a plate at the outlet side of a rolling mill and adjusting the roll gap difference of a work side and driving side based on the camber detection value. CONSTITUTION:The detection signal transmitted from a camber detector 5 is inputted to a control computer 6 and the feedback arithmetic part 7 of the control computer 6 operates the roll gap difference ALPHAS of the work side and driving side making the camber zero based on the camber detection value (t) and specific equation. The arithmetic result is sent to a controller 11, which adjusts the roll gap difference by outputting an operation signal ALPHAS respectively to the rolling reduction screw 13 of the work side and driving side.
