Abstract
PURPOSE:To achieve always good shape control, by proviously obtaining the relational formula of the variation in the roll crown and the noncontrolling point, and by correcting the noncontrolling point according to the value of variation in the roll crown, at performing the rolling work. CONSTITUTION:The computer 5 computes the roll crown from the detected value of the roll crown detector 6 and necessary rolling information, in order to obtain the roll's axial position and the roll bending force at the noncontroling point; these results are inputted to the operators 7, 11. The operator 7 operates the corrective value for the roll's axial position from above inputs and the detected value of the roll's axial position detector 8. The roll's axial position controller 9 receives this signal and actuates the axial roll shifter 10. The operator 11 operates the corrective value of the roll bending force from the signal of the computer and the detected value of the roll bending force detector 12. The roll bending force controller 13 receives this signal and actuates the roll bender 14. Hereby, the noncontrolling point can be corrected correspondingly to the rolling condition.
