| 摘 要： | 针对电站锅炉用大型截止阀体的制造新工艺一“剪切挤压”，利用数值模拟的方法对剪挤工艺进行研究，得到了成形过程中速度、应力、应变及温度场等的分布及金属流动规律，并通过物理模拟实验进行了验证，进而为获得阀体剪挤制造的最佳成形工艺参数提供可靠依据。

| 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. |
