Plug is one of the key deformation tools in cross piercing. Its function is turning a solid bar into a hollow bloom.
顶头是斜轧穿孔主要的变形工具之一，其作用是将实心管坯穿轧成一定壁厚的空心毛管。
In the cross piercing process, as the piercing precession power can not overcome the resistance force, it will lead to rear-jamming when rolling thick-wall tubes or high alloy tubes.
在斜轧穿孔过程中，由于轧件旋进力克服不了顶头的阻力，因此轧制厚壁管或高合金钢管时在穿孔后期造成后轧卡。
This new roll shape is very effective for improving pierced quality of low plastic steel and intensifying piercing process with larger cross angle.
这种新辊型对低塑性钢穿孔质量的改善和实现大前进角强化穿孔过程都有很大意义。
