We perform investigations aimed at the development of the main technological parameters of melting of high-chromium corrosion-resistant refractory nickel alloys in vacuum induction furnaces. We study the problems of refining of these alloys with removal of admixtures and gases in the course of melting in vacuum induction furnaces with crucibles whose mass does not exceed 1000 kg and also of their microalloying with rare-earth metals and, in particular, with lanthanum. We determined the influence of size of melting crucible and the angle of its inclination on the efficiency of refining of the melt. Finally, we compared the quality of the metal melted according to the developed parameters with a similar metal supplied from abroad.

我们进行的研究旨在开发在真空感应炉中熔化高铬耐火耐火镍合金的主要技术参数。我们研究了在质量不超过1000 kg的坩埚以及与稀土金属（尤其是镧）进行微合金化的真空感应炉中在熔化过程中去除混合物和气体来精炼这些合金的问题。 。我们确定了熔融坩埚的尺寸及其倾角对熔体精炼效率的影响。最后，我们根据开发的参数将熔融金属的质量与国外供应的类似金属进行了比较。
