Abstract
Este método para producir hierro reducido es un método para producir hierro reducido que produce hierro reducido mediante la reducción de óxido de hierro cargado en un horno de cuba, en donde una mezcla de gases que contiene un gas reductor y un gas nitrógeno, y tiene una temperatura predeterminada se sopla en el horno de cuba. El gas reductor contiene 90% en volumen o más de gas hidrógeno.
