Abstract
The melting induction furnace comprises, together with a casing (7) to which a lower sole plate (11) is added to form the central part of the structure, a removable inner crucible (1) composed of an internal layer (4) resisting heat and aggressiveness of the molten bath (20), an external layer (6) delimiting the crucible and an insulating intermediate layer (5). The crucible (1) is a disposable crucible and can be stored with its charge in an appropriate container. Heat losses are low, even when the casing (7) is cooled. Stresses due to differential thermal expansions are also very much reduced.
