Abstract

Se divulgan un procedimiento y un aparato para producir hierro. El procedimiento incluye un paso de reduccion directa de pasar un gas reductor a través de un lecho de a) un material que contiene hierro, tal como un mineral en trozos tabulares, y b) un material que forma el lecho, y producir un material de hierro reducido. El material que forma el lecho es un material que facilita la formacion del lecho de modo que hay un flujo hacia arriba optimo de un gas reductor a través del lecho. El procedimiento también incluye separar el material de hierro reducido y el material que forma el lecho. El material que forma el lecho puede ser usado nuevamente en el paso de reduccion directa. Reivindicacion 23: Una planta para producir hierro a partir de un material que contiene hierro, que incluye: a) una planta para reducir el material de alimentacion que contiene hierro y formar un material de hierro reducido pasando un gas reductor hacia arriba a través de un lecho del material de alimentacion y un material que forma el lecho (como se describe en la presente); y b) un aparato para separar el material de hierro reducido y el material que forma el lecho descargado del aparato de reduccion.A procedure and an apparatus for producing iron are disclosed. The process includes a direct reduction step of passing a reducing gas through a bed of a) an iron-containing material, such as a mineral in tabular pieces, and b) a material that forms the bed, and producing an iron material reduced. The material that forms the bed is a material that facilitates the formation of the bed so that there is an optimal upward flow of a reducing gas through the bed. The procedure also includes separating the reduced iron material and the material that forms the bed. The material that forms the bed can be used again in the direct reduction step. Claim 23: A plant for producing iron from an iron-containing material, which includes: a) a plant for reducing the iron-containing feedstock and forming a reduced iron material by passing a reducing gas upwardly through a bed of the feeding material and a material that forms the bed (as described herein); and b) an apparatus for separating the reduced iron material and the material that forms the discharged bed of the reduction apparatus.
