  • Patent number: 10767929
    Abstract: A furnace as described in this invention comprises a temperature regulating portion to assist in melting a non-ferrous material, such as an aluminium, and to reserve said material for the subsequent casting or injection molding procedure. The furnace provides a mean to eliminate an oxide, such as iron oxide, which generally floats on the top layer of a molten material inside a melting portion and a heating portion by preventing the flow of said oxide into the temperature regulating portion. A sensor or any detector that can detect the level of the molten material is utilized to measure the surface level of said molten material. A temperature regulating burner, which is a flat flame type, is utilized on the ceiling of the temperature regulating portion in order to prevent any oxidation reaction to occur as well as to reduce the concentration of oxygen inside the portion.
