Abstract

Un proceso para manufacturar productos moldeados de hierro reducido directo que comprende reducir, en un horno de reducción de tipo chimenea giratoria, compactos de un polvo que tiene un contenido de hierro total de 40% o más y contiene carbón fijo en una cantidad molar atómica de 0.7 a 1.5 veces la del oxígeno combinado con óxidos de metal que pueden reducirse en una atmósfera de monóxido de carbono a 1200°C, en donde los compactos se reducen en una atmósfera con la temperatura máxima de 1200 a 1420°C en compactos conteniendo hierro reducido directo que tiene una relación de monóxido de carbono/dióxido de carbono de 0.3 a 1.2, un contenido de hierro metálico de 50% por masa o más y un contenido de carbono de 5% por masa o menos y los compactos así reducidos son moldeados por compresión con un molde tipo rodillo de 500 a 800°C.
