摘要： 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.

摘要： A method of melting an aluminum charge having no more that 4% salt by mass, including during a melting phase, introducing fuel and oxidant via a burner operating at a first firing rate, the fuel and oxidant reacting to form a combustion zone above the aluminum charge, terminating the melting phase and commencing a transition phase when the aluminum charge is nearly completely molten, during the transition phase, reducing the firing rate of the burner to a second firing rate lower than the first firing rate, introducing a non-oxidizing gas at a first velocity to form a non-oxidizing zone between the combustion zone and the aluminum charge, and allowing the aluminum charge to become completely molten, and terminating the transition phase and commencing a tapping phase after the aluminum charge has become completely molten, and during the tapping phase, pouring the molten aluminum charge out of the furnace.
