Abstract：

Focused on the metal plastic forming of valve bodies for power plant boiler,a new process named “Shear Extrusion”is described in this paper.The numerical simulation analysis is carried out by using the 3\|D DEFORM software to predict the distribution of velocity,stress,strain and temperature fields during the forming process and the flow law of metal.Then the numerical simulation results are testified by simulative experiment.Finally,large\|size valve bodies have been successfully formed by the screw press.
