Abstract

PURPOSE:To make bending correction every moment according to a bending correction signal from function generator by putting the change with time of rolling speed into a function generator in which a relationship of rolling load change with rolling speed is memorized. CONSTITUTION:The speed meter 1 detects the change with time of the rolling speed of the operating roll 2 of the regulating rolling stand A and then puts the detected value into the function generator 3 every moment. The function generator 3 into which a relationship of rolling load change with the change of speed is beforehand memorized sends a bending correction signal according to the signal from the speed meter 1 to the correction controller 4. The correction controller 4 sends its output to the increase side bending oil pressure cylinder 5 through the oil pressure controlling valve 7 and also to the decrease side bending oil pressure cylinder 8 through the oil pressure controlling valve 10 every moment for control.
