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.
