利用真空悬浮熔炼技术熔炼了V和V-Ta合金、Nb和Nb-Ti、Nb-Zr合金、Mo和Mo-Ti合金、Ta和Ta-Ti合金以及Co-Cr-W合金等多种难熔金属及其合金。研究发现,采用真空悬浮熔炼技术熔炼难熔金属及其合金的优点是对原料的形态没有严格的要求,炉料整体熔化并且能得到充分的电磁搅拌,合金的成分和组织均匀;合金料可以随主料一起加入坩埚,也可以在熔炼过程中或熔炼结束前加入,使合金含量的精确性得到保证;真空熔炼的条件可以有效排除杂质元素;熔炼后可以根据需要直接铸造成形状和尺寸符合要求的产品。
V and V-Ta alloys, Nb and Nb-Ti, Nb-Zr alloys, Mo and Mo-Ti alloys, Ta and Ta-Ti alloys and Co-Cr-W alloys were melted by vacuum suspension melting Metal and its alloys. The study found that the use of vacuum melting smelting refractory metals and their alloys has the advantage of the form of the raw material is not stringent requirements, the overall melting of the charge and can be fully electromagnetic stirring, alloy composition and organization uniform; alloy material can be with the Lord Material together with the crucible can also be added in the melting process or before the end of melting, to ensure the accuracy of the alloy content; vacuum melting conditions can effectively exclude the impurity elements; product.
