Abstract
According to the invention, the skull pot is provided with the following characteristics: a pot wall ( ), a bottom ( ) and an induction coil ( ) which surrounds the pot wall ( ) and by means of which high-frequency energy can be coupled into the contents of the pot. The pot wall ( ) is made of a ring of metal pipes ( ) which can be connected to a cooling medium. Slits are embodied between adjacent metal pipes ( ). The metal pipes ( ) are bent at a right angle at the upper ends thereof in such a way that said pipes extend towards the outside, when the pot wall ( ) is viewed from above, and form a collar ( ). The collar ( ) is surrounded by an additional wall (upper wall ). The upper edge of said wall is situated on a higher level than the collar ( ) in such a way that the melt covers the collar ( ) during operation.
