Abstract:
A hybrid metal melting furnace uses a furnace lid to hold molten metal, while inhibiting reduction in the service life of burners of the furnace lid caused by long periods of exposure to high heat. This hybrid metal melting furnace includes a crucible for accommodating metal to be melted; and an induction coil causing induced current to flow through and heat the metal. A furnace lid which closes an opening in the crucible includes: a first furnace lid having burners for injecting flames into the crucible; and a second furnace lid which does not have the burners. When melting the metal, the first furnace lid is disposed in a position in which the opening is closed. When holding the molten metal in the crucible, the first furnace lid is removed from the opening, and the second furnace lid is disposed in the position in which the opening is closed.
