Abstract

A PPC (Plasma Progressive Casting) furnace with a water cooled mold and plural plasma torches was constructed to melt titanium and its alloys. Ingots of titanium and its alloys have been satisfactorily produced and satisfied chemical compositions and mehanical properties required for VAR double melted ingot.
This process has a distinctive advantage of efficient utilization of titanium and titanium alloys scrap.
