cross-country mill

The phenomenon of longitudinal fission seldom occurred during the process of tube plug drawing mill compared with empty-sunken steel tube. The problem which seldom cause transverse fissure in form of partial failure owing to uniform distribution of axial stress in cross section.

与空拔相比较，在短芯棒拔制过程中，纵裂现象一般不会发生，由于钢管轴向应力在横截面上分布均匀，一般也不会出现以局部破坏形式出现的横裂现象。
