摘要
介绍了在管材斜轧延伸机上使用拉力芯棒的优点。采用拉力芯棒可以提高速度效率，可以轧制薄壁管，还可减小不均匀变形及改善管材内表面质量。
Empolyment of the drawing mandrel for the cross-rolling pipe elongator has brought the mill such advantages as increased productivity,ability to produce lihgt-walled pies,lessening deformation uneveness as well as better inner/outer surface quality of the pipe.
