Abstract In order to study the crown control of six-high CVC mill, using nonlinear elastic-plastic finite element method, a 3D FE simulation model of six-high CVC rolling process was developed with the nonlinear FE software MSC.MARC. In the model, the elastic deformation of rolls and the elastic-plastic deformation of workpiece were coupled as a whole. Based on the model, the changes of work roll bending force, intermediate roll bending force, intermediate roll transverse shifting were simulated. The influence rules of the contact stress and crown control were obtained. The model and the calculated results can offer theoretic data and reference frame to establish the shape control model for six-high CVC mill.

Key words： six-high CVC contact stress crown control FEM
