Abstract

PURPOSE:To stably control the speed without neglecting the rolling mill's function of determining the speed, by placing a stand under the successive control, and by operating the successive amount to be controlled of adjoining stand to be controlled depending on the successive amount of said controlled stand. CONSTITUTION:Assume that the third stand 3 is now under the successive control. In the process for determining the rolling speed control signal h3 of the stand 3, a signal f3 possessing a value of successive amount to be controlled of the adjoining stand 2 to be controlled, and the signal C3 possessing the value of successive amount of the stand 3, are summed up by the adder 7a. The signal g2 possessing the value of speed variations, obtained by the adder 7a, is inputted to the divider 5a whose operational output, the signal e2, is inputted to the multiplier 6a. On the other hand, the successive signal C2 of the stand 2, and the reference signal b2 sent from the speed rheostat 2i of the stand 2, are inputted to the adder 4i shose addition output, the signal d2, is inputted to the multiplier 6a. The result of multiplication of these two signals d2, e2 is made the successive amount to be controlled of the stand 2 to be controlled.
