In order to improve the comprehensive shape control capability of a 2 180 mm super-wide tandem cold rolling mill, especially the edge drop control capability, the mechanical model was established for the flexible zone of SMS-EDC work roll, and the end structure and main parameters of the flexible zone of work roll were analyzed and calculated. The three-dimensional finite element model of roll system was built by the finite element software ANSYS15.0. Aiming at the SMS-EDC work roll, the influence coefficients of the central crown and edge drop were analyzed under different work roll’s parameters such as length and internal diameter of flexible area and under different shape control means such as bending force and shifting. Finally, the calculation formulas of roll shifting and bending force of work roll were given in the edge feedback control after deduction. The study can provide a theoretical foundation for the application of edge drop control means on 2 180 mm tandem cold rolling mill.
