摘要

综合电熔镁砂的低成本与石灰质的高稳定性及脱S、脱P特性等优点

开发了真空感应熔炼超纯合金用复合结构坩埚。利用现有真空感应炉

在不改造的情况下

通过制作简单的辅助工具

即可完成复合结构坩埚的打结。采用该坩埚冶炼的高镍合金中O、S、P等杂质含量明显降低

显著改善了材料的加工性能和使用性能。

Abstract

A composite crucible was developed for vacuum induction melting super-pure alloys by integrating the merits of low cost of fused magnesia and high stability as well as desulfurization and dephosphorization of calcareous crucible.On the basis of traditional vacuum induction melting furnace

the composite crucible can be realized by simple auxiliary tools

which can effectively decrease the cost of crucible.Impurities including oxygen

sulfur and phosphorus in the high Ni alloy can be obviously reduced with the composite crucible

greatly improving the properties of the alloy.
