Abstract

Le procédé de fabrication dans un convertisseur à oxygène à partir de matériaux métalliques ferreux, en particulier à partir d'un matériau de rebut, consiste à charger ces matériaux qui sont ensuite chauffés et fondus en apportant un gaz contenant de l'oxygène, tel de l'air oxygéné, par en-dessous, et par apport d'oxygène par les côtés. Pendant la fusion, la teneur en oxygène du gaz contenant de l'oxygène dont l'apport se fait par dessous est augmentée jusqu'à 100 %, puis l'affinage de la coulée ferrocarbonée a lieu.
