Title:
HYBRID METAL MELTING FURNACE
Document Type and Number:
WIPO Patent Application WO/2017/056849
Kind Code:
A1
Abstract:
The purpose of the present invention is to provide a hybrid metal melting furnace which is capable of using a furnace lid to hold molten metal, while inhibiting reduction in the service life of burners provided to the furnace lid caused by exposure to high heat for long periods of time. This hybrid metal melting furnace 10 is provided with: a crucible 11 in which a metal to be melted is accommodated; and an induction coil 24 which causes an induced current to flow through the metal to be melted, to heat the metal to be melted. A furnace lid 13, 14 which closes the top of an opening 21 in the crucible 11 includes: a first furnace lid 13 having, provided thereto, burners 41 for injecting flames into the crucible 11; and a second furnace lid 14 which does not have the burners 41 provided thereto. When melting the metal to be melted, the first furnace lid 13 is disposed in a position in which the opening 21 is closed. When holding the molten metal in the crucible 11, the first furnace lid 13 is removed from the opening 21, and the second furnace lid 14 is disposed in the position in which the opening 21 is closed.
