Abstract

PURPOSE:To control properly the sheet shape and sheet crown of a steel strip by inputting the detecting values of a crown meter and a shape meter located respectively at the exit of a rolling mill to a feedback control device and correcting a bending force of each stand, in rolling the strip by a tandem finishing mill. CONSTITUTION:In rolling a steel strip 4 by a six-stage tandem finishing mill, the sheet crown and sheet shape of the strip 4 are detected by a crown meter 8 and a shape meter 9 arranged respectively at the exit of the mill, to input the detected results to a feedback control device 7. The device 7 outputs an additional signal, basing on these sheet crown and sheet shape, to the bending-correcting output of a predictive control device 6 which houses a model equation for predicting the thermal crown of a roll with the passage of time, to perform a feedback control. The rolling material 4 is rolled by correcting the deviation of a bending force by the work roll of each stage, to obtain a sheet material having prescribed sheet shape and sheet crown at the exit.
