Abstract

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.
