Abstract
PURPOSE:To improve a plate flatness by performing a rolling reduction calculation on the allowable max. load of a rolling mill from an initial thickness of a slab to an initial thickness at starting a shape control, a since then, by performing the rolling reduction calculation based on an object crown and each pass steepness until up to the thickness on and after the product. CONSTITUTION:Previously, the thickness Hc at starting the object crown control and a pattern of each pass steepness lambda are decided. In this case, the object crown is obtained from the required specification of the product, the pattern of each pass steepness lambda is set as the object steepness lambdan, the max. lug wave steepness lambdamax, steepness correcting gradient DELTAlambda. In the pass exceeding the shape control starting thickness Hc, the rolling reduction schedule is calculated in the state where the max. allowable load of the rolling mill is the control condition. Succeeding rolling reduction schedule to the product plate thickness is calculated based on the object crown and the steepness of each pass. Because the rolling is performed by estimating the shape deformation, the flatness of the product is improved.
