Abstract

La presente invencion trata de proporcionar un metodo para producir hierro metalico, que comprende las etapas de suministrar una mezcla que contiene un agente reductor carbonoso y oxidos de hierro sobre una solera de un horno de fusion por reduccion del tipo de solera movil, calentando la mezcla para la fusion por reduccion de los oxidos de hierro, enfriando el hierro metalico asi obtenido y descargando el hierro metalico hacia el exterior del horno para su recuperacion. El metodo permite eliminar o reparar facilmente la superficie de una solera, incluso si en la superficie de la solera esta enterrado hierro metalico en polvo o incluso si la superficie de la solera ha sufrido infiltracion de escorias y erosion, permitiendo incrementar el factor de disponibilidad y buen mantenimiento de la solera, y se aplica adecuadamente para funcionamiento continuo a largo plazo. La presente invencion consiste en un metodo para producir hierro metalico, donde un material de solera se extiende en forma de una capa sobre la solera antes del suministro de la mezcla, formando de esta manera una solera renovable capaz de ser renovada, y produciendose el hierro metalico mientras se esta renovando una parte o la totalidad de la solera renovable que se habia deteriorado durante el funcionamiento, empleando material de solera.
