Abstract

PURPOSE: To improve the exactness of the rolling load, by using a sheet thickness possible to minimize the interstand difference of the ratio of the computed rolling load to the actual rolling load, in recomputing the rolling load of each stand, and by learning the roll gap, etc.
CONSTITUTION: A material to be rolled is passed successively through plural rolling stands whose roll gap, etc., are previously computed; on the basis of actual measurements obtained from the said rolling work practiced by plural rolling stands, the roll gap, etc., of each stand are again learned; for this purpose, the ratio of a computed rolling load of the first stand to the actual rolling load and the similar ratio of the second stand are obtained. The thickness at each stand for minimizing the difference between said two ratios is obtained. By using this thickness, the rolling load of each stand is again obtained in order to learn the roll gap, etc., of each stand. By the present method, the thickness of the rolled sheet is made more exact.
