Elastic deformation of rollers in the process of sheets and strips rolling significantly the quality of profile shape. In order to study this elastic deformation,a mechanical model of contact among rollers and between work roll and rolled piece was constructed on the basis of elastic basis beam theory，and simulated by spring. An analytical mathematical model of the elastic deformation of rollers in 6-h mill was presented. A method which coupled the distribution of section shape of rolled piece and rolling pressure were proposed to iteratively compute the elastic deformation of rollers and the section shape of rolled piece. At last, a finite element model based on the nonlinear contact theory of elastic deformation of rollers was formulated using the software of MSC.MENTAT/MARC. The computed results showed that the section shape of rolled piece and the crown of strip calculated using the analytical method and the finite element model are similar to that of the field measurement, which effectively verifies the proposed research methods and the formulated model.
