Abstract

PURPOSE: To obtain target plate crown and flat plate shape of good accuracy by subsequently calculating the inlet side plate thicknesses of the respective stands after the stand where the inlet side plate thickness becomes smaller than the specific minimum plate thickness under the crown rate fixed conditions under which plate crown forecast formulas and plate reaction forecast formulas are simultaneously held.
CONSTITUTION: According to rolling sizes, the minimum plate thickness at which the effect of the inlet side plate crown is not affected to the outlet side plate crown is obtained. In the hot strip mills in which plural rolling stands are continuously disposed, the respective inlet side plate thicknesses of the rolling stands of the stages after the rolling stand on the lowermost stream side where the inlet plate thickness is smaller than the above-mentioned minimum plate thickness are calculated by letting plate crown forecast formulas and rolling reaction forecast formulas hold simultaneously from the product target plate thickness and the product traget plate crown and solving under the crown rate fixed conditions, whereby the traget plate crowns and outlet side plate thicknesses are subsequently determined.
