ABSTRACT:
A method and apparatus for optimizing melting of titanium for processing into ingots or end products. The apparatus provides a main hearth, a plurality of optional refining hearths, and a plurality of casting molds or direct molds whereby direct arc electrodes melt the titanium in the main hearth while plasma torches melt the titanium in the refining chambers and/or adjacent the molds. Each of the direct arc electrodes and plasma torches is extendable and retractable into the melting environment and moveable in a circular pivoting or side to side linear motion.
