Abstract
A rolling mill shape control apparatus for a flat material comprises a thermal crown calculator which calculates a thermal crown magnitude in a widthwise direction of rolls as based on rolling history information after a change in vertical spacing of the rolls, a roll wear calculator which calculates a wear magnitude of the rolls as based on rolling history information after the rearrangement of the rolls, an optimum rolling temperature distribution calculator which calculates an optimum rolling temperature distribution in a widthwise direction of the flat material on the basis of the calculated results of both the thermal crown calculator and the roll wear calculator and a reference bending force corresponding to maximum bending correction, a thermometer which detects a widthwise temperature distribution of the flat material, a heating/cooling device which can separately heat/cool a plurality of parts of the flat material divided in the widthwise direction thereof, and a heating/cooling controller which compares an optimum rolling temperature distribution signal and a temperature distribution signal so as to control the heating/cooling device between the signals.
