Abstract

PURPOSE: To improve the accuracy of thickness, by correcting the thickness deviation signal detected in the upstream rolling mill with the deviation signal obtained from the thickness deviation detected in the downstream rolling mill, and by effecting the feedback control so as to converge the thickness deviation in the downstream rolling mill on zero.
CONSTITUTION: Before the rolling mill 2 bites the material 3 to be rolled, the ratio a1 of initial value is set in the correction circuit 14. When the rolling mill 2 begins to bite the material 3, the correction circuit 14 operates the equations I and II. The signal 14a, possessing the value obtained from the equation II, is inputted to the setter 6, and the equation III is arithmetically operated. Next, the thickness deviation signal ΔH produced from the memory 5 is corrected by the setter 6 as shown by the equation III in order to obtain the aimed screw position signal ΔS effecting in converging the thickness deviation signal Δh2 on zero. This signal ΔS is inputted to the screw position controller 7, which then adjusts the screw position of the rolling mill 2.
