Analysis on Temperature Field of Work-piece during Cross Wedge Rolling

摘要：

　　Based on the rigid-plastic deformation finite element method and the heat transfer theories,the forming process of cross wedge rolling was simulated with the finite element software DEFORM-3D.The temperature field of the rolled piece during the forming process was analyzed.The results show that the temperature gradient in the outer of the work-piece is sometimes very large and temperature near the contact deformation zone is the lowest while temperature near the center of the rolled-piece keeps relatively stable and even rises slightly.Research results provide a basis for further study on metal flow and accurate shaping of work-piece during cross wedge rolling.
