Abstract

PROCEDE DE FABRICATION DE METAL SPONGIEUX, PAR REDUCTION DISCONTINUE D'OXYDES METALLIQUES, DANS UN SYSTEME OU DES LITS SEPARES DE MATERIAU METALLIFERE SONT TRAITES SIMULTANEMENT DANS UN REACTEUR DE REFROIDISSEMENT ET AU MOINS DEUX REACTEURS DE REDUCTION, EN UTILISANT UN GAZ REDUCTEUR COMPOSE ESSENTIELLEMENT DE CO ET H. ON STABILISE LE GAZ REDUCTEUR SORTANT DU REACTEUR DE REFROIDISSEMENT EN L'ALIMENTANT EN PARALLELE DANS LES REACTEURS DE REDUCTION. DE PREFERENCE LE GAZ, AVANT D'ENTRER DANS LES REACTEURS DE REDUCTION, EST CHAUFFE A AU MOINS 900C SANS COMBUSTION. CECI PEUT ETRE EFFECTUE EN CHAUFFANT D'ABORD LE GAZ A 800C PUIS EN LE FAISANT PASSER SUR UN CATALYSEUR. CECI REDUIT LA CONSOMMATION EN GAZ REDUCTEUR POUR UN POURCENTAGE DONNE DE LA METALLISATION DU METAL SPONGIEUX. LA COURBEA EST OBTENUE DANS UN PROCEDE CLASSIQUE ET LES COURBES B, C ET D DANS DES MODES DE REALISATION DE L'INVENTION.
