一、前言影响钛合金在民用机器上使用的最大障碍是价格高。因此人们一直希望能在冶炼、熔炼、加工过程中降低原料价格。其方法之一是残料回收。由于钛合金是难加工的材料,材料的成品率低,所以在一次加工及二次加工过程中产生了大量残料。可是现在对这些残料还没有有效的熔炼方法,所以其再生利用受到限制。目前使用的残料熔炼法有自耗电极式及 I. Preface The biggest obstacle affecting the use of titanium alloy on civilian machines is the high price. Therefore, people always hope that in the smelting, melting, processing and lower raw material prices. One of its methods is the recovery of residual material. Titanium alloy is difficult to process the material, the material yield is low, so in a process and secondary processing has produced a large number of debris. However, there is no effective smelting method for these residues now, so its recycling is limited. Reusable smelting method currently used has a consumable electrode type and
