Plasma-Arc Remelting of Titanium Alloys,

Abstract

Vacuum plasma-arc melting has the following advantages over vacuum arc melting with the consumable electrode: the possibility of the remelting of lump, noncompact charge; the possibility of the velocity control of melting, maintaining metal in the molten state and, therefore, its additional degassing; and, simpler vacuum equipment. Plasma-arc melting in vacuum (0.4-0.5 mm Hg.) has advantages over plasma-arc melting in weakly rarefied atmosphere (75-100 mm Hg.): the higher degree of degassing of melt; the higher thermal efficiency of process; the less consumption of working gas; the possibility of using low-voltage current sources for vacuum arc furnaces.
