METHOD OF AND AN APPARATUS FOR DETERMINING AN OPTIMUM SCHEDULE OF OPERATION FOR REVERSIBLE HOT ROLLING MILLS

摘要

A method of and an apparatus for determining such an optimum schedule of operation as to provide a shortest total rolling time for reversible hot rolling mills, wherein an initial schedule of operation for initial passes is determined based upon the properties of a material to be rolled, rolling conditions and standard resistance to deformation of the material, and based upon the actual resistance to deformation obtained in the initial passes, an optimum schedule of operation for subsequent passes is determined so that it provides a shortest total rolling time.
