Abstract

PURPOSE:To carry out titled control at high accuracy, by detecting respective rolling load on the operating side and the driving side of the rolling mill, and by adjusting the left and the right roll gaps depending on the ratio between the difference and sum of two rolling loads. CONSTITUTION:The rolling loads Pw and Pd respectively loaded on the backup rolls 1, 2, through the screw are detected by the left and the right load cells 8, 9. These detected load signals Pw*, Pd*, are sent to the operator 10 which then operates the rate of load difference, rdf*=Pdf*/Pm*=(Pw*-Pd*)/ (Pw*+Pd*). This arithmetic result is input to the proportion operator 11 and the differentiator 12, and the proportional position action signal and the derivative action signal from above operators are summed up by the adder 13. Then the signal Sdf from the adder 13 is sent to the left and the right draft position setters 6, 7, through the draft position controller 14, and the left and the right roll gaps are adjusted correspondingly to the size of the Zigzag motion Yc.
