Abstract

La presente invencion se refiere a un método de producir hierro metálico granular, que comprende: calentar una materia prima formada que comprende unreductor carbonoso y una sustancia que contiene oxido de hierro en un horno de fusion de reduccion pa ra someter el oxido de hierro contenido en la materiaprima formada a reduccion en estado solido; y carburizar hierro reducido resultante de la reduccion en estado solido con carbono contenido en el reductorcarbonoso, para hacer que el hierro reducido se funda, a la vez que se separan los componentes de ganga conendios en la materia prima fomrada y haciendo que elhierro metálico fundido resultante coalesca al hierro metálico granular, en el que un gas atmosférico presente cerca de la materia prim a formada en el paso decarburacion y fusion tiene un grado de reduccion no inferior a 0,5. La presente invencion también se refiere a un método de producir hierro metálico, quecomprende formar una capa de deposito que contiene escoria producida en el proceso de fusion de reduccion sobre refractarios de solera, protegiendo por lotanto los refractarios de solera a la vez que se produce el hierro metálico. La presente invencion se refiere además a un dispositivo para suministrar unamateria prima au xiliar a una solera de un horno de fusion de reduccion del tipo de solera movil adaptado para producir hierro metálico, incluyendo, eldispositivo de un conducto de suministro que conecta verticalmente con una porcion de techo del horno.
