Abstract

EN UN PROCEDIMIENTO PARA LA PRODUCCION DE HIERRO BRUTO LIQUIDO O PRODUCTOS BASICOS DE ACERO LIQUIDO Y HIERRO ESPONJOSO DE MINERAL DE HIERRO, EL MINERAL DE HIERRO ES DIRECTAMENTE REDUCIDO EN UNA PRIMERA ZONA DE REDUCCION (4) A HIERRO ESPONJOSO Y EL HIERRO ESPONJOSO ES FUNDIDO EN UNA ZONA DE GASIFICACION DE FUNDICION (10) MEDIANTE ADICION DE PORTADORES DE CARBONO Y DE GAS OXIGENADO, DE MANERA QUE SE PRODUCE UN GAS DE REDUCCION QUE CONTIENE CO Y H{SUB,2} QUE ES INTRODUCIDO EN LA PRIMERA ZONA DE REDUCCION (4), DONDE ES TRANSFORMADO Y EXTRAIDO COMO GAS DE EXPORTACION. EL GAS DE EXPORTACION EXTRAIDO ES SOMETIDO A UNA ELIMINACION DE CO{SUB,2} Y A UN CALENTAMIENTO Y, A CONTINUACION, ES ENVIADO COMO GAS DE REDUCCION LIBRE, AL MENOS EN SU MAYOR PARTE, DE CO{SUB,2} A AL MENOS OTRA ZONA DE REDUCCION (29) PARA LA REDUCCION DIRECTA DEL MINERAL DE HIERRO. PARA OBTENER UN APROVECHAMIENTO LO MAS COMPLETO POSIBLE DEL GAS DE EXPORTACION EXTRAIDO DE LA SEGNDA ZONA DE REDUCCION (29), PARA EL CALENTAMIENTO DEL GAS DE EXPORTACION PROCEDENTE DE LA PRIMERA ZONA DE REDUCCION (4) SE UTILIZA EL CALOR DEL GAS DE EXPORTACION QUE SALE DE LA SEGUNDA ZONA DE REDUCCION (29).
