Abstract
PURPOSE:To make possible highly accurate and rapid shape controlling by forecasting the asymmetrical shapes produced by asymmetrical factors such as temp. differences of the material to be rolled on the inlet side of a rolling mill having a pair of axially movable rolls and performing the correction of asymmetrical shapes. CONSTITUTION:In the rolling mill having at least a pair of axially movable rolls 2, 3, the apparatus is constituted of the asymmetrical factor detectors, such as thickness gauges 17, 18', material position detectors 14, 15, thermometers 20, 21, etc. provided on the inlet side, the calculators 23, 25 which extract asymmetrical components from the asymmetrical shapes produced by the above-described factors and create vectors, the calculator 26 which selects an optimum correction device out of the right and left bending force differences for correcting said asymmetrical shapes, a calculator 35 which calculates the optimum correction amount of the correcting devices, and a screw-down command device 31 which controls set value, whereby the correction of the asymmetrical shapes is accomplished. These eliminate the existence of any shape insufficiency owing to time delay and make possible rapid shape controlling.
