Abstract
Method and apparatus for melting reactive metallic materials, such as for example titanium base alloys and other reactive alloys, by selective and sequential induction heating of a plurality of solid alloy charge components segregated in a refractory melting vessel in a manner to effect rapid top-to-bottom melting that avoids harmful reaction of the melt with refractory melting vessel material and contamination of the melt.
