Abstract (en)
[origin: DE19939781A1] Skull crucible (1) comprises a wall (1.1), a base (1.2) and an induction coil (2) surrounding the wall and via which high frequency energy is coupled to contents of the crucible. The crucible wall is formed of a crown or metal tubes for the coolant. Intermediate spaces are formed between neighboring metal tubes. The base has a run-off connected to a sleeve (4). The inlet end (4.1) of the sleeve protrudes into the inner chamber of the crucible so that the melt can be removed through the base without the danger of impairing its quality. Preferred Features: The upper edge of the sleeve is at a height of between a tenth to a halt of the melt height measured from the base of the crucible.
