Recycling of titanium alloys in plasma furnace

Abstract

The scheme of prototype stand for reactive metals and alloys melting and the results of experimental investi-gation on recycling process of titanium alloy grade TiAl6V4 are presented in this paper. On the basis of chemical compositions and gases contents in analysis the alloy (before and after remelting process) it was shown that the application of prototype stand is a very effective way of the recycling process of titanium alloys. The application of plasma jet generated from inert gas as a heat source inside the melting chamber enables creating the atmos-phere with low partial pressure of oxygen, nitrogen and hydrogen.
