一、前言各国纯钛管材的生产,由于设备等条件的不同,各具有不同的工艺特点。但综合分析来看,主要是采用二次熔炼铸锭—锻造(初轧)—挤压(斜轧穿孔)一冷轧(冷拔)的工艺生产钛管。这种传统工艺的缺点是工序复杂、成品率低。由生产实践表明:在制管过程中,由锻造工序所引起的氧化、切头尾及其随后的扒皮金属损失总量占整个锭重的四分之一左右。 I. Preface The production of pure titanium pipes in various countries has different technological characteristics due to the different conditions of equipment and so on. However, a comprehensive analysis shows that the titanium tube is mainly produced by the process of secondary melting ingot-forging (initial rolling) -extrusion (oblique rolling and perforation) -cold rolling (cold drawing). The disadvantage of this traditional process is the process complexity, low yield. From the production practice shows that: in the process of pipe making, the total amount of oxidation, head and tail metal loss caused by the forging process accounts for about a quarter of the total weight of the spindle.
