Abstract

L'invention concerne un procédé pour la préparation d'acier à partir de fonte sulfurée, dans lequel la fonte est désulfurée au moyen d'agents contenant du calcium, avant son chargement dans la cuve d'affinage. Selon l'invention, la scorie de désulfuration est chargée conjointement avec la fonte dans la cuve d'affinage et soumise avant l'affinage à un traitement oxydant par addition d'agents contenant de l'oxygène.
