Abstract
PURPOSE: To increase or decrease pass angles, to prevent the fluctuations in the rate of camber in the longitudinal direction of a material and to improve yield by moving the anticorrugating roll on the exit side of skin pass mills downward during accelerating of skin pass and upward during decelerating.
CONSTITUTION: In an operator 21, the rate of L camber is calculated from the skin pass speed detected by a speed detector 19, and the height position of an anticorrugating roll 7 for decreasing the rate of L camber is calculated. The calculated value and the detected value of a position detector 20 are compared and the required extent of movement of the roll 7 is outputted to a motor 15. Then, the motor 15 lowers the roll 7 in the direction of an increasing pass angle during accelerating of the skin pass speed, thereby increasing a reduction ratio. Con versely, during decelerating of the skin pass speed, it moves the roll 7 upward in the direction of the decreasing pass angle, thereby decreasing the reduction ratio and controlling the rate of L camber to zero or a constant low value.
