Crucible having two induction coils

In a crucible (3), a central base section (27) is formed of a multiplicity of palisades (5, 5',...) and also designed in such a way that the palisades (5, 5', 5",...) together form a vessel or a tank (7) in whose base part an outflow or melt outlet (8) is arranged, at least two induct...

Beschreibung
Zusammenfassung:	In a crucible (3), a central base section (27) is formed of a multiplicity of palisades (5, 5',...) and also designed in such a way that the palisades (5, 5', 5",...) together form a vessel or a tank (7) in whose base part an outflow or melt outlet (8) is arranged, at least two induction coils (10, 11) being provided, the one coil (10) of which surrounds the neck and/or upper part of the central base section (27) from the outside and the other coil (11) the outlet (8). The palisades (5, 5', 5",...) are separated from each other by means of individual gaps (6, 6', 6",...) running radially outwards from the centre, the electromagnetic field at least of the upper coil (10) acting on the charge contained in the crucible (3) through the gaps (6, 6', 6",...) and the coils (10, 11) being individually controllable.
