Abstract
L'invention a pour objet un procédé de coulée continue d'une bande d'acier inoxydable austénitique directement à partir de métal liquide de composition, exprimée en pourcentages pondéraux: C ~ 0,08 %; Si ~ 1 %; Mn ~ 2 %; P ~ 0,045 %; S ~ 0,030 %; Cr compris entre 17,0 et 20,0 %; Ni compris entre 8,0 et 10,5 % sur une machine de coulée sur une ou entre deux parois mobiles dont la surface extérieure est pourvue de fossettes et dont on inerte la zone environnant le ménisque avec un gaz d'inertage de composition maîtrisée, caractérisé en ce que: - on confère audit métal liquide un rapport Créqu/Niéqu supérieur à 1,55, avec: Créqu = % Cr + 1,37 x % Mo+ 1,5 x % Si + 2 x % Nb + 3 x % Ti et Niéqu = % Ni + 0,31 x % Mn + 22 x % C + 14,2 x % N + % Cu; - on utilise une ou des parois mobiles dont l'ensemble de la surface comporte des fossettes jointives de diamètre compris entre 100 et 1500 .mu.m et de profondeur comprise entre 20 et 150 .mu.m; - et on utilise un gaz d'inertage consistant au moins partiellement en un gaz soluble dans l'acier. L'invention a également pour objet une installation de coulée pour la mise en oeuvre de ce procédé.
