METHOD For REFINING alloys from impurities

摘要

The invention relates to metallurgy, in particular the foundry production. A method for refining alloys from impurities includes their inert gas blowing in a vacuum chamber and plasma heating at the dilution, at that refining is carried out by evaporation of impurities from the alloys by heating the plasma electric arc or plasma jet on the melt layer, which circulates over the partition in the vacuum chamber, and thickness of this layer and the power, which is supplied for the evaporation of impurities, which regulate the draft intensity in the vacuum chamber. The method allows to increase the strength and performance characteristics of alloys due to their efficient refining from harmful and excess impurities.
