Numerical analysis of lateral movement of a metal strip during cold rolling

Abstract

A model and numerical algorithm for the analysis of lateral movement of a metal strip during cold rolling are presented. The model includes a simplified description of the physical processes responsible for strip lateral movement, such as plastic deformation of the strip, elastic deformation of rolls, deformation and dynamics of the strip outside the plastic reduction region. The study is motivated by the operational problem experienced in the metal rolling industry. Numerical simulations reveal possible mechanisms of strip track-off and identify issues inviting further study.
