Research on the Roll Contour Configuration for Schedule Free Rolling in Hot Wide Strip Mills

Article Preview

Abstract:

In order to satisfy the flexible rolling schedule of hot steel production, principles and theory for choice of roll contour configuration were described. Additionally, the several typical roll contour configurations which are popular in the world nowadays, and their shape control capability for “rolling of large quantities of strips in same width” and “rolling by strip width increase in sequence” were analyzed with established finite element model of roll stacks. Then, the optimum roll contour configuration for SFR (schedule free rolling) was obtained.
