The invention is a microwave gun and arc plasma torch furnace used to refine titanium, Ti, from titanium dioxide, TiO.sub.2, powder. The furnace includes high frequency microwave emitters that create a high temperature zone strongly vibrating the titanium dioxide powder, TiO.sub.2, and lengthening and weakening the valence bonds in the titanium dioxide powder, TiO.sub.2, titanium, Ti, and oxygen, O, atoms. The furnace also uses nitrogen arc plasma torch generators to generate a N.sup.+ plasma to completely disassociate the titanium, Ti, and oxygen, O, atoms into titanium ions, Ti.sup.+ and oxygen ions, O.sup., and permitting the formation of nitrogen dioxide, NO.sub.2, and melted titanium, Ti.

The present invention provides a melting furnace capable of suppressing oxidation of molten materials and improving the quality of the molten materials. As shown in FIG. 3, a melting furnace 1 includes a melting portion 2 to which a metal material is supplied; a burner 4 for melting the metal material in the melting portion 2 into a molten material; a heating portion 5 that receives the molten material from the melting portion 2 to raise the temperature of the molten material; a temperature regulating portion 6 that receives the molten material from the heating portion 5 and stores the molten material; a separator 7 that separates the heating portion 5 and the temperature regulating portion 6, wherein the lower portion 70 of the separator 7 is immersed in the molten material to form, below the separator 7, an inlet 71 that allows the introduction of the molten material from the heating portion 5 into the temperature regulating portion 6; an immersion heater 10 wherein at least part of the immersion heater 10 is immersed in the molten material in the temperature regulating portion 6 to thereby heat the molten material; and a gas introduction path 72 that is formed in the separator 7, and that introduces combustion gas from the burner 4 into a space above the molten material in the temperature regulating portion 6; wherein the burner 4 is controlled so that the combustion gas has an oxygen concentration of 5% or less.
