Abstract

PURPOSE: To realize perfect shape control of strips, by detecting shape defects corrugating at short pitch in a narrow range in the strip side edge part by means of a shape detector at the rolling mill exit side, and enlarging the screw-down or rolling speed of the rolling mill to increase the thermal crown of work roll.
CONSTITUTION: A strip 1 is cold-rolled by work rolls 2, 2', and shape defects in the strip side edge part are detected by a shape detector 10. The output signal from the detector 10 is processed in a shape signal processing circuit 11, and the shape of the strip is decided. When undulation, above a specified level occurs, an undulation occurrence signal is inputted from the circuit 11 into an operation control circuit 12, from which is outputted a signal to correct the screw-down or rolling speed of the rolling mill at a predetermined rate. The corrected control output is outputted to a screw-down control device 13, and the corrected rolling speed is outputted to a speed control device 14. As the screw-down increases, the deformation heat of the strip increases, and the temperature in the contact parts of the rolls 2, 2' with the strip is elevated to enlarge the thermal crown of the rolls 2, 2', thereby eliminating the undulation.
