摘要：

通过设定合理的送进角和辗轧角，并应用有限元方法成功地模拟了空心双金属管坯的斜轧扩径过程，研究了双金属复合管坯变形各阶段的轧制力、等效塑性应变、温度场分布。结果表明，在稳定扩径阶段的扩径区出现轧制力最大值，是空心双金属复合管坯内外层材料最易发生缺陷的区域，工件内部的高温有利于内外层材料在界面处的协调变形。同时进行了空心双金属管坯斜轧扩径试验，金相、扫描电镜照片显示双金属复合无缝钢管界面冶金结合良好，充分证明了双金属管坯斜轧扩径工艺的可行性。

The cross expanding process of the hollow bimetallic tube was simulated successfully by finite element method (FEM) under reasonable feed angle and toe angle, and the distributions of rolling force, equivalent plastic strains and temperature for hollow bimetallic tube in the deformation zone were studied. The results show that the maximum rolling force happens in the expanding zone of the stable expanding stage where the defect appears easily for inner and outer layer material of the hollow bimetallic tube. However, the high temperature inside the workpiece is advantageous to the deformation of the interface between inner and outer layer material in coordination. Furthermore, the metallographic image and SEM image show the good interfacial metallurgical bonding in the interface of bimetallic seamless steel pipes, and the feasibility of cross expanding of hollow bimetallic tubes is verified.
