Abstract
PURPOSE: To carry out the tensionless control and constant tension control for the rolling mill group on purpose to improve the effect of computer control, by correcting the torque arm represented by the ratio between the rolling torque and rolling load, against the variation of the rolling condition.
CONSTITUTION: In the computing model for controlling the rolling mill group to temsionless or constant tension condition, the torque arm, which is represented by the ratio between the rolling torque and rolling load, is corrected against such variations of the rolling condition as the temperature change in the rolled material, the change in the settled roll gap, etc., using the curve, etc., prepared depending on the computing formula; hereby, the real torque arm is obtained. According to this method, the decline of the controlling accuracy can be restricted to the minimum, the stable control for the continuous rolling work is established, and the uniform rolled product can be always manufactured. Besides, the forecast computation for the torque arm in the next and following passes can be made possible.
