WATER-COOLED AND INDUCTION HEATED CRUCIBLE Russian patent published in 2005 - IPC

FIELD: electrical engineering; water-cooled and induction heated crucibles.

SUBSTANCE: proposed crucible that can be used for melting minerals, mineral-like materials, ceramic materials, glasses and other glass-like materials characterized in high melting point and also for embedding radioactive and nonradioactive wastes into glass and/or glass-like materials compatible with them has water-cooled cover, water-cooled drain valve, water-cooled drain assembly, water-cooled drain assembly cover, charging assembly, internal feeder, gas outlet pipe, guide bar, upper header, cylindrical case, lower header, flat water-cooled bottom , and inductor. Crucible incorporates provision for regulating melt drainage capacity and for maintaining constant chemical composition of drained melt compared with that of material fed to water-cooled crucible.

EFFECT: reduced heat loss and power requirement, simplified design, reduced accident probability, enhanced quality of drained melt.
