1) piercing rod for copper pipes
铜管穿孔针
2) arbor
[英]['ɑ:bə] [美]['ɑrbɚ]
穿孔针
1.
Calculation of tension acting on arbor in process of extruding aluminium alloy tube without lubrication;
铝合金管材无润滑挤压穿孔针拉力的计算
2.
The extrusion length is mainly determined by arbor strength when aluminium alloy tube is extruded without lubrication based on the calculation of arbor′s pulling force.
根据对穿孔针所受拉力的计算 ,得出如何确定无润滑挤压铝合金管材时合理的铸锭长度 ,以减少挤压时的断针现象。
3) holes formed after copper needle pulled out
铜针拔出孔
4) pipeline partial corrosion
管线穿孔
5) tube perforation
炉管穿孔
6) pierced shell
穿孔毛管
1.
But as well as the applicaton of horizontal continuous casting billets , the amount of disfigurement of pierced shell inner and outer fold is increasing apparently,especially the outer fold is the very seriousone.
适当减小导板距,增大轧辊距,减小穿孔椭圆度;适当提高管坯加热温度和延长加热时间,均能显著减少穿孔毛管的外折缺陷,提高金属收得率。
