Abstract:

Plasma melting equipment of production scale was established by modification of an existing nonconsumable electrode melting facility. A 1.2 megawatt power capability plasma torch was operated up to a power level of 600 KW and several melts were made using nickel base alloy and titanium alloy scrap. The argon gas plasmarc has been shown to be a useful high heat source for melt- consolidation of super alloy and types of scrap including reactive metal scrap into suitable electrode shapes for subsequent consumable remelting.
