Abstract：

The key problem for skew rolling copper ball at room temperature is the good plasticity of copper bar,and the temperature of copper is key factor to influence the plasticity of the copper.But the temperature field of the workpiece can not be gotten by common methods.The temperature field of the workpiece was simulated and analysed by DEFORM-3D.It shows that the temperature of the neck is higher than the temperature of the other parts of the workpiece.In the neck,the highest temperature is on the contact point with ridge slope,and the lowest temperature is on the center of the neck.The temperature on the surface of the neck rises and decreases alternately,and the temperature of the center of the neck is constant firstly then rises gradually.
