crucible furnace

crucible furnace

      metallurgical furnace consisting essentially of a pot of refractory material that can be sealed. Crucibles of graphite or of high-grade fire clay were formerly used in the steel industry, heated directly by fire; modern high-quality steel is produced by refining in air-evacuated crucibles heated by induction. Metals such as titanium, which must be protected from air while hot, are melted and annealed in hermetically sealed crucibles.
