A Numerical Simulation of Strip Profile in a 6-High Cold Rolling Mill

Abstract

Shape control is always a key issue in the six-high rolling mill, in which the shifting of the intermediate roll and the work roll have been used to enhance the shape control capability. In this paper, a finite element method (FEM) model has been developed to simultaneously simulate the strip deformation and the roll stack deformation for the six-high rolling mill. The effects of the work-roll bending, the shifting of the intermediate roll and the work roll on the strip crown and edge drop are discussed in details. Results have shown that both higher bending force and more roll shifting will significantly reduce the strip crown. The edge drop is also reduced with the bending force and the roll shifting.

A Study on Potential Strip Shape Control of High‐Strength Steel during Hot Pinch Rolling Process

“…[ 22 ] A FEM model has been developed to simultaneously simulate the strip deformation and the roll stack deformation for a six‐high rolling mill. [ 23 ] The effects of work‐roll bending, intermediate roll shifting, and the work roll contour on the strip crown and edge drop were discussed in details. For high‐precision profile and flatness control ability of electrical steel strip with different widths during SFR campaign, the ASR contour, which is suitable for all strip widths (ASR‐C) is developed.…”
