Beschreibung
Zusammenfassung:	Feeding metal to a crucible (1) by levitation comprises: (a) a feed opening (6) arranged at the bottom of the crucible (1) and underneath an induction coil (4) surrounding the crucible (1); (b) a bar (10) of metal is introduced and lifted via the feed opening (6) into the crucible (1) inside the induction coil (4); and (c) the liquid metal (5) is moved from the edge of the feed opening (6) by a levitation effect. L'invention propose un procédé pour alimenter en métal un creuset (1) à lévitation. Un tel procédé est remarquable en ce qu'on dispose une ouverture d'alimentation (6) au fond du creuset (1), en ce qu'on fait remonter une barre (10) de métal par ladite ouverture d'alimentation (6) et en ce qu'on écarte le métal liquide (5) du bord de l'ouverture d'alimentation (6) par l'effet de lévitation.
