Abstract

L'INVENTION CONCERNE UN PROCEDE DE FABRICATION D'ACIER A PARTIR DE FERRAILLES, D'EPONGE DE FER OU D'AUTRES SUBSTANCES FERREUSES METALLIQUES, A L'AIDE D'UN CONVERTISSEUR COMPORTANT DES TUYERES DANS SON FOND. LE PROCEDE EST CARACTERISE PAR LE FAIT QU'ON INTRODUIT LA CHARGE DE MATIERE DANS LE CONVERTISSEUR, DANS LA ZONE DE PAROI LATERALE DUQUEL DES BRULEURS A COMBUSTIBLE-OXYGENE SONT PLACES AU-DESSUS DES TUYERES, DE MANIERE QUE LADITE MATIERE SOIT FONDUE PAR LES BRULEURS ET QUE, LORSQU'IL S'EST FORME UN FOND LIQUIDE, ON INJECTE DU CARBONE FINEMENT DIVISE ET DE L'OXYGENE SEPAREMENT L'UN DE L'AUTRE DANS LE BAIN DE FUSION PAR L'INTERMEDIAIRE DES TUYERES DISPOSEES DANS LA ZONE DE FOND. APPLICATION A LA SIDERURGIE.
