An Investigation on Contact Pressure and Roll Spalling Problem for Four High Mill
Abstract:Finite element method was adopted to investigate the principle for calculation and technical points of the contact pressure transversal distribution between work and backup rolls for four high mill under arbitrary rolling conditions. The roll spalling problem was analyzed, which influenced roll life for cold rolling, and the methods to porevent roll premature failure and extend its service life were suggested accordingly.
Keywords:Finite element method Four high mill Spalling
