Abstract

Dans ce procédé, le moule (1) comprenant une cavité de moulage (3A) délimitée par une lingotière (2), un noyau (4) et un fond (27), est disposé à l'intérieur d'une enceinte de coulée sous vide (5) comprenant, à sa partie supérieure, un moyen (9) d'introduction de métal liquide. Un moyen (11A,11 ') de réception et de répartition de métal liquide adapté pour recevoir l'acier liquide introduit dans l'enceinte de coulée sous vide (5) et pour redistribuer le métal liquide dans la cavité de moulage (3A) est disposé à la partie supérieure de la cavité de moulage (3A). On introduit le métal liquide dans l'enceinte (5) de façon à former un premier jet d'acier liquide (50) sous vide pour déverser le métal liquide sur le moyen de réception et de répartition (11A,11') et à former au moins un deuxième jet d'acier liquide (52) sous vide provenant du moyen de réception et de répartition (11A, 11') et aboutissant dans la cavité de moulage (3A) de façon à remplir de métal liquide la cavité de moulage (3A).
