Abstract

PURPOSE: To carry out the titled control at more superior accuracy, by controlling the screw position according to the quantity of adjustment at the position corresponding to each position of the rolled material in the former pass.
CONSTITUTION: At the present pass, the elongation F/M of the rolling mill due to rolling load is corrected by the lock-in level corrector 13, and is memorized as the of lock-on in the lock-on memory 9. The difference between the corrected value of lock-on and the value of F/M detected at present pass is inputted to the operator 11 which memorizes the variation of the sheet gauge as the function of the turning angle of the work roll 2, and also, inputs the variation of sheet gauge memorized at the former pass, to the screw down device 15, and operates the necessary movement of the screw 3; then, the operator 11 gives an instruction for the movement of the screw 3 to the screw down device 5, at the position of the turning angle θ2 corresponding to the turning angle θ1. The control at the next pass is carried out similarly.
