Abstract

L'INVENTION CONCERNE UN PROCEDE POUR OBTENIR DES BRIQUETTES DESTINEES A DES FOURS VERTICAUX DE REDUCTION. CE PROCEDE CONSISTE A VERIFIER ETOU DIMINUER LA DIMENSION DES GRAINS D'OXYDE DE FER, TEL QUE LE SOUS-PRODUIT DE PROCEDES DE L'INDUSTRIE SIDERURGIQUE, DANS UN TAMIS13 ET UN BROYEUR18, A SECHER L'OXYDE DANS UN DESSICCATEUR19, A MELANGER CET OXYDE DANS UN MELANGEUR26 AVEC DE 0,5 A 6 D'UN LIANT, ET A METTRE LE MELANGE SOUS FORME DE BRIQUETTES DANS UNE MACHINE27. CE PROCEDE PERMET D'UTILISER DIRECTEMENT LES BRIQUETTES DANS LE PROCEDE DE REDUCTION DANS DES CORNUES VERTICALES.THE INVENTION CONCERNS A PROCESS FOR OBTAINING BRIQUETTES INTENDED FOR VERTICAL REDUCTION OVENS. THIS PROCESS CONSISTS OF CHECKING AND OR DECREASING THE SIZE OF IRON OXIDE GRAINS, SUCH AS THE BY-PRODUCT OF STEEL INDUSTRY PROCESSES, IN A SIEVE13 AND A CRUSHER18, DRYING THE OXIDE IN A DESICCATOR19, MIXING THIS OXIDE IN A MIXER26 WITH 0.5 TO 6 OF A BINDER, AND PUT THE MIXTURE IN THE FORM OF BRIQUETTES IN A MACHINE27. THIS PROCESS ALLOWS THE DIRECT USE OF THE BRIQUETTES IN THE REDUCTION PROCESS IN VERTICAL CORNUES.
