Abstract

PURPOSE: To improve shape accuracy by providing shape detectors on both sides of the reversible rolling mills and changing over and alternately performing feedback controlling and feed forward controlling in every pass.
CONSTITUTION: When a rolling material 10 is rolled from left to right, a flip-flop 142 generates the signal on the Q side and is led to a delay device 15 via gate circuit 143. On the other hand, the output of a shape detector 7 is taken in a feedback control unit 12 through circuit 146. The output of the delay device 15 is taken into a feed forward control unit 16 and operates and outputs the respectie shape control signals. These signals are added in respective adders 21 thru 25 and are applied to a shape regulating means. Next, when rolling is accomplished from right to left, the flip-flop 142 generates the signal from the Q' side and the signal of the shape detector 7 is taken in the feed forward control unit 16 through the delay device 15 via cirruit 145 and the signal of the detector 8 is taken in the feedback control unit 12.
