Abstract
SE PRESENTA UN PROCEDIMIENTO PARA PRODUCIR HIERRO EN LINGOTES QUE UTILIZA LA REDUCCION DIRECTA DE LA MENA DE HIERRO EN UNA ETAPA DE PRE-REDUCCION SEGUIDA POR UNA ETAPA DE REDUCCION FINAL. EN LA ETAPA DE PRE-REDUCCION LA MENA DE HIERRO SE PRE-REDUCE EN UN CICLON DE FUSION (1) POR MEDIO DE UN GAS DE PROCESAMIENTO DE REDUCCION QUE SE ORIGINA A PARTIR DE LA ETAPA DE REDUCCION FINAL. SE PRODUCE UNA POS-COMBUSTION EN EL GAS DE PROCESAMIENTO DE REDUCCION EN EL CICLON DE FUSION DE MANERA QUE LA MENA DE HIERRO EN EL CICLON DE FUSION SE FUNDA AL MENOS PARCIALMENTE. LA MENA DE HIERRO PARCIALMENTE FUNDIDA PASA HACIA ABAJO AL INTERIOR DE UN VASO METALURGICO (4) SITUADO POR DEBAJO DEL CICLON EN EL CUAL TIENE LUGAR LA REDUCCION FINAL MEDIANTE EL SUMINISTRO DE CARBON Y OXIGENO, FORMANDO DE ESTA FORMA UN GAS DE PROCESAMIENTO DE REDUCCION. SE PRODUCE UNA POS-COMBUSTION PARCIAL EN EL GAS DE PROCESAMIENTO DE REDUCCION EN EL VASO METALURGICO POR MEDIO DEL OXIGENO SUMINISTRADO AL MISMO. LA PROPORCION DE POS-COMBUSTION DEL GAS QUE SALE DEL VASO METALURGICO NO ES MAYOR DEL 0.55. EL CARBON SE SUMINISTRA DIRECTAMENTE AL INTERIOR DE LA CAPA DE ESCORIA (7) DE MANERA QUE LA POS-COMBUSTION PARCIAL EN EL VASO METALURGICO SE EFECTUE AL MENOS PARCIALMENTE EN LA CAPA DE ESCORIA.
