三辊斜轧穿孔生产TA2管坯工艺研究

研究了三辊斜轧穿孔法生产φ50min×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φ48mm,棒坯加热制度930～950℃/40～50mi...

Study on Technology Using Three- Roll Rotary Piercing Method to Produce TA2 Tube

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.
