Abstract

PURPOSE: To make good the sheet shape, by controlling the flow rate of coolant and temperature distribution of the roll coolant injection nozzle group nearby the sheet edge, so as to increase the gradient of the thermal crown.
CONSTITUTION: Only the signal nearby the sheet edge being produced from the shape detector is regressed with the previously set shape function, and thus obtained regression coefficient is sent as the negative feedback to the separate bending force and reverse bending force of the roll bending control system II. Besides, the absolute value of the regression coefficient, as the control command for the gradient of thermal crown of the work roll surface nearby the sheet edge, is used for controlling the flow rate and temperature distribution of the roll coolant injection nozzle group nearby the sheet edge so as to increase the gradient of thermal crown. Accordingly, the shape distortion at sheet edge is corrected by the rolling load controlled in control systems A and B, and by the separate bending force and reverse bending force controlled in the bending control system II.
