三辊联合穿轧工艺及变形区刚塑性有限元分析

Three roller combined piercing elongating tubemaking technology and rigid plastic finite element analysis in deformation zone

三辊联合穿轧机将穿孔和轧管工序集于一体，实现一道次可获得各种精度的钢管生产新工艺，本文介绍了这种工艺的方法，对变形区的刚塑性进行了有限元分析。

Three roller combined piercing elongating tubemaking mill is a new type of machines that combine tube piercing and rolling into one machine ,producing high quality tube within one pass. This paper presents this kind of the process and also a rigid plastic finite element analysis in deformation zone.
