Analyses on the Roller Elastic Deformation of 4-high CVC Mill

The influence function method of roller elastic deformation was introduced so as to analyze its effects on profile shape.The roller elastic deformation of 4-high CVC cold mill was calculated by analytic program using C language.The results show that the deflection of work roller and backup roller are in asymmetric"v"style,the inter-roller flattening and pressure are in"s"style.In the whole controlled area the change of backup roller deflection and the flattening between work roller and strip is small,the change of work roller deflection and inter-roller flattening is large,especially at the edge.
