Abstract
PURPOSE: To operate and detect the tension at high accuracy, by obtaining the tension torque arm so as to make the torque arm to be the untensioned torque arm, at an arbitrary clock time during the rolling work.
CONSTITUTION: The front tension Ti is induced from the rolling torque Gi, the rolling load Pi, the torque arm, the front tension torque, arm, the back tension torque arm, and the back tension, with respect to the i-th stand 2. The rolled material 1 is bitten into the i-th stand 2 and is before being bitten into the (i+1)-th stand; under this condition, the back tension Ti-1 of the i-th stand 2 is used, and thus obtained rolling torque and the rolling load of the i-th stand 2 are corrected to obtain the reference torque arm. Besides, according to the torque arm variation under the following untensioned condition and the reference torque arm, the torque arm of the i-th stand under the untensioned condition is obtained, and the interstand tension of the continuous rolling mill is detected at high accuracy.
