Abstract

La presente invención se refiere a método mejorado para la reducción gaseosa de mineral de hierro particulado, en forma de trozos, pélete o mezclas de ellos, que comprende reducir un lecho móvil de dicho mineral ded hierro particulado que desciende verticalmente con flujo másico en una zona de reducción a temperaturas superiores a 700 grados C; estrechar el lecho de partículas reducidas, convergentemente en una zona de descarga inferior hasta por lo menos una salida de descarga; descargar las partículas reducidas de dichas salidas de descarga a una temperatura promedio superior a 500 grados C; caracterizado por que dicha zona de descarga está definida por una superficie limitante relativamente lisa y por enfriar, por lo menos una porción superior de dicha superficie limitante, suficientemente para enfriar las partículas reducidas que están en contacto con dicha superficie a una velocidad de enfriamiento y a un grado adecuados para incrementar, por razón de dicho enfriamiento, la velocidad de flujo efectiva de las partículas en dicha superficie en comparación con la velocidad de flujo de las mismas en ausencia de dicho enfriamiento.
