Abstract
In setting roll gaps of a rolling mill having stands arranged in tandem, the resistance to deformation of a workpiece in each of the stands is calculated on the basis of a cumulative strain in each stand, with strain of the workpiece which is in an entrance side of the mill and in a soaked state being zero. The resistance to deformation of the soaked workpiece is obtained in each stand, so that the accuracy of estimation of the resistance to deformation is improved. Thus, a precise roll gap setting becomes possible, resulting in a product of a thickness accurately coincident with an objective thickness.
