Abstract

SE PRESENTA UN METODO Y UN APARATO PARA LA PRODUCCION DE HIERRO A PARTIR DE COMPUESTOS DE HIERRO. HAY UNA PRIMERA ETAPA DE PREREDUCCION DE LOS COMPUESTOS DE HIERRO EN UNA PRIMERA CAMARA (1) QUE TIENE UNA PARED ROTACIONALMENTE SIMETRICA (3), Y UNA SEGUNDA ETAPA DE UNA REDUCCION ADICIONAL DE LOS COMPUESTOS DE HIERRO EN UNA SEGUNDA CAMARA (4) POR DEBAJO DE LA PRIMERA CAMARA, EL COMBUSTIBLE Y EL OXIGENO SON SUMINISTRADOS A LA SEGUNDA CAMARA. UN GAS DE REDUCCION PASA HACIA ARRIBA AL INTERIOR DE LA PRIMERA CAMARA PARA EFECTUAR LA PRE-REDUCCION EN LA MISMA. EL OXIGENO ES SUMINISTRADO A LA PRIMERA CAMARA. LOS COMPUESTOS DE HIERRO EN LA PRIMERA CAMARA SE FUNDEN AL MENOS PARCIALMENTE Y FLUYEN ENTONCES HACIA ABAJO A LO LARGO DE LA PARED HACIA DICHA SEGUNDA CAMARA. LOS COMPUESTOS DE HIERRO SE INTRODUCEN EN EL INTERIOR DE LA PRIMERA CAMARA EN FORMA DE PARTICULAS Y POR MEDIO DE UN GAS PORTADOR QUE SUMINISTRA UNO O MAS CHORROS. EL OXIGENO ES SUMINISTRADO AL INTERIOR DE LA PRIMERA CAMARA AL MENOS PARCIALMENTE EN FORMA DE UNO O MAS CHORROS QUE TIENEN COMPONENTES TANGENCIALES. LA VELOCIDAD DE INTRODUCCION DEL OXIGENO ES MAYOR QUE LA VELOCIDAD DE INTRODUCCION DE LOS COMPUESTOS DE HIERRO EN LOS CHORROS DE LOS MISMOS, MIENTRAS QUE LA VELOCIDAD DE INTRODUCCION DE LOS COMPUESTOS DE HIERRO ES TAL QUE LAS PARTICULAS ALCANZAN LA PARED DE LA PRIMERA CAMARA EN UN ESTADO AL MENOS PARCIALMENTE FUNDIDO.
