The invention relates to a skull pot ( 1 ) for melting, crystallizing or refining inorganic substances. Said pot comprises a pot wall ( 1.1 ), a pot bottom ( 1.2 ), an induction coil ( 2 ) which surrounds the pot wall ( 1.1 ) and by means of which high-frequency energy can be coupled into the content of the pot. The pot wall ( 1.1 ) is formed by a ring of metal pipes which can be connected to a cooling medium. Slits are embodied between adjacent metal pipes. The bottom ( 1.2 ) is provided with a discharge for the melt ( 3 ). A sleeve ( 4 ) is allocated to the discharge. The admission end ( 4.1 ) of the sleeve ( 4 ) protrudes far into the inner chamber of the skull pot ( 1 ) in such a way that, during use, the melt ( 3 ) can be withdrawn through the crystallized bottom layer ( 3.3 ) in a controlled manner without the danger of impairing quality. |
