Abstract

UN METODO Y APARATO PARA LA REDUCCION GASEOSA DE MINERALES DE HIERRO PARTICULADOS, EN DONDE EL MINERAL SE INTRODUCE EN UN REACTOR REDUCTOR DIRECTO DE LECHO MOVIL VERTICAL, SE REDUCE DENTRO DE EL Y SE DESCARGA COMO UNA ESPONJA DE HIERRO CALIENTE. SE CARGA EL MINERAL EN LA PARTE SUPERIOR DE LA ZONA DE REDUCCION DEL HORNO EN DONDE EL LECHO DE PARTICULAS QUE DESCIENDEN POR GRAVEDAD ES REDUCIDO POR UN GAS REDUCTOR CALIENTE COMPUESTO EN SU MAYOR PARTE DE MONOXIDO DE CARBONO E HIDROGENO. EL GAS REDUCTOR CALIENTE SE DIVIDE EN DOS PARTES, UNA PRIMERA PARTE QUE FLUYE HACIA ARRIBA A TRAVES DE LA ZONA DE REDUCCION PARA REDUCIR LOS MINERALES QUE SE ENCUENTRAN DENTRO DE ELLA Y UNA SEGUNDA PARTE QUE FLUYE HACIA ABAJO A TRAVES DE UNA ZONA DE DESCARGA INFERIOR PARA MANTENER EL LECHO A UN NIVEL DE TEMPERATURA ADECUADO. FINALMENTE EL PRODUCTO DE ESPONJA DE HIERRO SE DESCARGA DE LA PARTE INFERIOR DE LA ZONA DE DESCARGA DEL HORNO Y SE TRANSPORTA, POR EJEMPLO, PARA SER FUNDIDA EN UN HORNO DE ARCO ELECTRICO O PARA SER BRIQUETEADO EN UNA MAQUINA BRIQUETEADORA ACOPLADA AL REACTOR DE REDUCCION.
