Abstract Taking the six-high five-stand cold tandem mill of 2 230 mm as research object，the three-dimensional nonlinear mill simulation model with intermediate roll using ESS profile wase stablished through the ABAQUS finite element software platform. By numerical simulation，the variation law of the shape regulation region was analyzed under the combined action of shape control means including work roll bending， intermediate roll bending and intermediate roll transverse movement. Meanwhile， the control performance of different parameters including work roll bending force，intermediate roll bending force and intermediate roll transverse movement value to quadratic crown and quartic crown of the strip was researched systematically. The application results show that the mill with ESS profile has a good control effect on the shape and transverse thickness of the strip.
