Abstract

Se describe un proceso de reduccion directa para materiales que contienenoxido de hierro. El gas de síntesis se mezcla con gas de la parte superior producido durante la reduccion directa de los materiales que contienen oxido de hierro. A fin de evitar o reducir el polvoreamiento metálico provocado por un contenido incrementado de CO del gas de reduccion con una técnica y equipo simple, la relacion CO/CO2 del gas de reduccion se ajusta a un valor predeterminado de 1 a 3.
