Abstract

PURPOSE: To improve the accuracy of the centering control, at aligning the position of the coiled strip to the center of the rolling mill, by changing the control constant correspondingly to the change of the line speed of the strip, and by reducing the displacement of the payoff reel correspondingly to the reduction in the coil load.
CONSTITUTION: The coiled strip is uncoiled from the payoff reel 1, and the strip is driven to run on the tension roll 2 and is transported to the rolling mill 4. The edge of the strip is detected by the edge detector 3, and the hydraulic cylinder 8 is actuated to displace the payoff reel in the axial direction. Hereupon, the speedmeter 12 always detects the line speed of the strip, and the parameter change-over circuit 14 is switched through the indicator 13; hereby, the control constant of the PI controller 10 is changed. Besides, the position of the payoff reel is sent as feedback to the amplifier 6 through the position signal generator 11, and the hydraulic pressure of the cylinder is adjustably reduced with the reduction of the coil load.
