Abstract

Un proceso de reducción directa comprende proporcionar un horno vertical de una planta de reducción directa para reducir el óxido de hierro con un gas de reducción; proporcionar un horno de fusión de hierro directamente reducido; y acoplar un canal de descarga entre una salida de descarga del horno vertical de reducción directa y una entrada del horno de fusión de hierro directamente reducido; en el que el hierro directamente reducido y el gas de reducción del flujo de horno vertical a través del canal de descarga y el gas de reducción controla la atmósfera del horno de fusión al ambiente de reducción.
