Abstract
PURPOSE: To reduce the rolling power, and to greatly reduce the upward and downward cambers of the rolled product, by reversing the relation of magnitude of the torque between the adjoining rolling mills.
CONSTITUTION: When the sheet is threaded, the torques, to be impressed on both rolls on purpose to prevent the upward and downward cambers of the rolled product, are equalized. Next, during the ordinary rolling work, a signal for holding constant the number of revolution of the roll is given to the driving system Ms provided with the speed controller in consideration of the pass schedule, the rolling speed, etc.; at the same time, the torque of the motor in the driving system Mc provided with the torque controller is reduce within the limits not to cause the slip of the roll taking the sign into consideration, and the torque difference is given to the upper and lower rolls of each stand. As a result, the pass schedule, speed, etc., are controlled to normal by Ms over through whole stands, the torque difference between upper and lower rolls is controlled by Mc, and the magnitude of upper and lower roll torques alternately change its places at each stand; hereby, the camber free product can be obtained with the reduced energy consumption.
