Induction crucible-channel furnace, for metal melting, holding and-or metallurgical treatment, has a metal-filled furnace chamber surrounding an internal induction coil

摘要

An induction crucible-channel furnace, having a metal-filled furnace chamber surrounding an induction coil, is new. An induction crucible-channel furnace has a preferably annular metal-filled furnace chamber surrounding a preferably cylindrical induction coil, the external field of which provides electromagnetic induction of current in the metal. Preferred Features: The furnace chamber may also be surrounded by an external induction coil providing an internal field for inducing current in the metal.
