METHOD FOR CONTROLLING TIP CAMBER IN HOT ROLLING

PURPOSE: To execute tip camber control excellent in accuracy by which the tip camber is reduced as less as possible by taking respective variations of transformation factor and cumlative strain distribution in the direction of the thickness of a rolled stock into consideration. CONSTITUTION: Based on the transformation factor and cumlative strain distribution in the direction of the thickness in accordance with the temp. distribution of the rolled stock, vertically asymmetrical cooling conditions for making the amount of the tip camber in the pass of the controlled system not larger than a prescribed value are calculated and, by these vertically asymmetrical cooling conditions, the rolled stock is cooled by the cooling means on the inlet side of the rolling mill in the pass of the controlled system.
