目前广泛采用二次真空自耗电弧熔炼工艺生产可锻钛合金锭。熔化电极与成锭相结合最大限度地简化了熔炼炉结构,并大大地提高了可靠性。然而,还有下列几个问题没有获得满意的解决: 1.当生产钛合金部件时,加入炉料中的回炉废料和金属屑必须大量增加,并有合理的冶金平衡组织; Currently widely used in secondary vacuum consumable arc melting process to produce ductile titanium alloy ingots. Melting the electrode in combination with the ingot minimizes the melting furnace structure and greatly improves reliability. However, there are several issues that have not been satisfactorily addressed: 1. Recycling scrap and metal shavings added to the charge must be significantly increased with reasonable metallurgical balances when producing titanium alloy parts;
