Abstract
At least three palisades are set up vertically and parallel to each other, spaced apart, and distributed around the arc of a circle in such a way as to surround the melt. A circular, plate-shaped part forms the bottom of the crucible and supports the palisades, the palisades being provided at least in part with cavities through which a coolant flows, and with an induction coil, which is wound around the outside of the palisades a certain distance away and carries an alternating current. At least two groups of palisades are connected to each other by means of an electrically conductive bar or pipe socket, each palisade group or each individual palisade being electrically insulated with respect to adjacent palisade groups or individual palisades.
