Abstract

Le trou de coulée selon l'invention se distingue en ce qu'il comporte un ajutage rapporté en matière réfractaire comportant une partie superieure cylindrique 38 de diamètre supérieur à celui de la partie inférieure cylindrique 36 et un élément coaxial 40 comportant un orifice 42 d'un diamètre inférieur à celui de la partie 38 de façon à établir au-dessus de la surface 44 une zone de stagnation relative du métal et qu'en dessous de l'élément 40 la veine contractée ne vienne pas en contact avec les surfaces situées en dessous de l'élément 40 pour empêcher l'accumulation d'inclusions d'oxydes qui autrement risqueraient de réduire le diamètre de l'orifice. Un tel dispositif convient en particulier pour la coulée continue d'aciers calmés par l'aluminium.
