摘　　要：研究了三辊斜轧穿孔法生产Φ50 mm×5 mm TA2管坯的生产工艺。通过TA2棒坯不同加热温度对穿透率的影响、不同径向压下量对穿孔后管坯直径的影响、穿孔头尺寸对管坯壁厚的影响、棒坯直径与管坯直径关系的研究,确定了三辊斜轧穿孔法生产纯钛管坯的具体工艺参数：棒坯规格Φ48 mm,棒坯加热制度930~950℃/40~50min,顶头前探量26~32 mm,径向压下量15%~20%。The research on the technology using three-roll rotary piercing method to produce TA2 50 mm×5 mm tube was performed.The optimal parameters for the processes have been obtained：heat treatment at 930~950 ℃ for 40~50 min,probe depth of perforation head 26 ~32 mm,radial rolling reduction 15% ~20% for 48 mm billet through researching effects of various kinds of processes parameters on properties.The mechanical properties and structure of the titanium and titanium alloy tubes produced by using the three-roll rotary piercing method technology can meet the requirements of technical conditions and application.
