Abstract

Un método para producir hierro reducido directo incluye los pasos de: secar un material crudo de hierro oxidado, seleccionado de un grupo que incluye al hierro mineral y polvo de la producción de hierro, generado en un proceso de producción de hierro que tiene un contenido de humedad predeterminado, mezclar el material crudo de hierro oxidado sometido a la etapa de secado y un material reductor que tiene un contenido de humedad predeterminado para obtener una mezcla, pulverizar la mezcla obtenida en la etapa de mezclado y tamizarla en un tamiz a través del cual el 80% de los sólidos que pasen tenga un diámetro de partícula de 70 µm a 500 µm; amasar la mezcla después de que se ajuste el contenido de humedad de la mezcla sometida a la etapa de pulverización, aglomerar la mezcla sometida a la etapa de amasado para ser aglomerada, y reducir el aglomerado obtenido en la etapa de aglomeración mediante un horno de crisol rotativo para generar hierro reducido directo.
