Induction melting furnace with metered discharge

摘要

An induction melting furnace comprises a melt chamber for heating a melt either directly by magnetic induction, or indirectly by magnetic induction heating of the melt chamber, or a combination of the two, and a meter chamber connected to the melt chamber for providing a metered discharge of the melt from the furnace. A gas can be injected into the furnace to provide a blanket over the surface of the melt in the melt chamber and a pressurized flush of the metered discharge of the melt from the meter chamber.
