Abstract

PURPOSE:To eliminate the influence of the mechanical vibration, and to perform the stable control without causing the tension fluctuation, by adding a circuit to the control system of the motor driven looper in order to send the differential signal of the speed of the looper motor as the positive feedback with a specified gain back to the electric current control system. CONSTITUTION:At controlling the amount of the loop in the hot strip continuous rolling mill, the amount of loop between the stands 1a, 1b, respectively on the feed- in side and the run-out side in the mill, is maintained constant by the loop amount control system for controlling the loop amount through the speeds Vn, Vn+1, of the stands 1a, 1b. On the other hand, the tension between the stands 1a, 1b, is maintained constant by the electric current control system of the motor driven looper. To this control system, the differential circuit 11 for the looper angle signal N is added; hereby, the differential signal of the looper angle detector 7 is inputted to the multiplier 12 of the gain KN, and is sent back to the electric current controller 8 as the positive feedback. By the present method, even if there is a mechanical vibration, an effect, similar to that obtained by reducing the moment of inertia of the lopper, can be obtained, and the loop amount control system with the quick responsiveness can be realized.
