Abstract

PURPOSE: To smoothly, accurately control the thickness of the strip before and after the changing action for the thickness of strip, by interrupting the thickness control at the transition period for changing the thickness of traveling strip, by renewing the reference value at changing the thickness, and by restarting the rolling force adjusting thickness control.
CONSTITUTION: When the thickness of the traveling strip is to be changed, the thickness controlling action is interrupted. Before or at the same time as the end of rolling work for the thickness-changed traveling strip, soon or a specified time after receiving the signal from the timing input device 7 for the rolling work for the thickness changed traveling strip, the detected values of the screw position detector 3 and the rolling force detector 4 are inputted to the rolling force adjusting AGC device 5, and are rememorized as the renewed reference screw position and the reference rolling force; these rememorized values are used in computing and renewing the reference run-out side thickness of the strip started for controlling the drive of the screw position controller 6 so as to make the thickness deviation zero.
