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.

The present disclosure relates to a method and a smelting unit (1) for the pyrometallurgical smelting of metal-containing raw materials, waste materials and/or secondary waste materials (M) in the presence of an oxidizing, reducing and/or inert gas (G).

A method for refining a titanium material, in which oxygen contained in a titanium material made of a pure titanium, a titanium alloy or an intermetallic compound containing titanium as one of main components is removed, the method includes: a first melting step of melting the titanium material under a noble gas atmosphere containing 5 to 70 vol % of hydrogen, thereby introducing hydrogen into a melt of the titanium material; and a second melting step of melting the titanium material into which hydrogen has been introduced in the first melting step under a noble gas atmosphere, thereby removing oxygen contained in the titanium material from the melt of the titanium material together with the hydrogen. Each of the first melting step and the second melting step is carried out at least once.
