A Mathematical Model on Strip Profile and Shape in Cold Tandem Rolling

Abstract

A mathematical model by which the transverse thickness profile and the shape of finished strip in a cold tandem rolling are predicted is developed by taking account of lateral metal flow and the distribution of the front tension. Calculated profiles are in good agreement with measured profiles obtained by rolling experiments in a production tandem mill. Calculated shapes are found to be similar to observed shapes obtained by rolling experiments in a experimental mill and also the production mill except for the case of center buckle.
