Abstract：By means of 3D Finite Element Method (FEM), a new 6-high CVC cold rolling mill model, which couples CVC profile, rolling force distribution between rolls, elastic deformation of rollers, and elastic-plastic deformation of strip, was built. The rolling force distribution between rolls and elastic-plastic deformation of roll and workpiece were obtained by the iteration calculation method. The model was verified in comparison with the actual rolling schedule data. The absolute error between the simulated results and the actual values is obtained to be less than 10 μm, and relative error is less than 1%. Thus, the simulated results are in good agreement with the measured data. Consequently, the effect of flatness actuators such as intermediate roll bending, intermediate roll shifting and work roll bending on secondary crown and quartic crown was studied and actual center-edge buckles of the industrial products of wide and thin strips in the cold rolling process were successfully eliminated according to the research results.
