Abstract
PURPOSE:To control the chamber with the accuracy higher than in the conventional practice in thick plate rolling by changing the wedge rate (edge quantity/ average plate thickness) of a rolling material before and after rolling. CONSTITUTION:The wedge quantity h1df obtd. by inputting the outputs from detectors 3, 3' for the camber shape (curvature distribution x1) and right and left thicknesses detected 5 during or after the rolling in, for example, the pass just before the final pass is fed to an arithmetic unit 7. The change of the target wedge rate DELTAPSI12<t> in the rolling stage of the final pass and the target wedge quantity R2df<t> after the rolling are calculated and stored according to the prescribed equation together with the preset elongation lambda, plate width (b), average plate thickness h1 before the final pass and the average plate thickness h2 after the final pass. The difference Sdf<t> between the right and left roll gaps of the final pass are calculated and stored from the predicted value YCP of the off centering quantity obt. in the above-mentioned manner and the target wedge quantity. The right and left roll gaps are set by operating right and left roll gap setters 8, 8' according to the stored gap difference and the rolling is executed in the final pass.
