本文应用MARC有限元软件并采用三维热力耦合的弹塑性有限元法，对不锈钢／碳钢双金属复合无缝钢管斜轧过程进行了有限元分析，得到了坯料断面孔型变形图，分析得出了应力、应变与温度场的分布，根据数值计算结果绘制了管坯斜轧过程中辊缝下断面沿圆周的轴向应力、环向及径向应力分布曲线，并根据应力分布特点解释了钢管斜轧过程成形机理。研究成果可以为工艺参数的设计提供参考。

The numerical simulation of the cross-rolling stainless steel/carbon steel double metal composite seamless steel tube process was conducted through the finite element analysis of the three-dimensional thermo-mechanical coupled elastic-plastic by applying the MSC.MARC software.Based on the numerical simulation, the character of stress,strain and temperature distribution parameters during the two roll cross-rolling were obtained by the finite element analysis,and acquired the section pass deformation figure.The distribution of the axial stress,circle stress and radial stress were drawn in the cross-rolling roll gap profile along the circle.The mechanism of tube cross-rolling process was explained according to the stress distribution.The results of the research can be applied to the design of the cross-rolling forming process.
