A method of melting an alloy in an induction furnace wherein the formulation of high melting temperature refractory oxides formed by the reaction of one or more of the raw materials being melted with oxygen is avoided by the introduction of boron. The method comprises charging an induction furnace with metallic raw materials, at least a portion of which contain greater than 100 ppm of oxygen, charging said induction furnace with boron in an amount of at least .02% by weight of the total charge, melting said charge materials in said induction furnace and thereafter pouring the melt from the furnace into a mould for solidification and formation of an ingot. |
