ABSTRACT:
In a melting crucible (3) a central bottom portion (27) is formed of a plurality of palisades (5) and is shaped so that the palisades together form a vessel or a pot (7) having a centrally disposed spout or outlet (8). Two independently powered induction coils (10, 11) are provided, one coil (10) externally surrounding the collar or upper part of the central bottom portion (27), and the other coil (11) externally surrounding the spout (8). The palisades (5) are separated from one another by individual gaps (6) running radially outwardly from the center, while the electromagnetic field of at least the upper coil (10) acts on the charge contained in the melting crucible through the gaps (6).
