Abstract

Un método para la producción de hierro fundido a partir de mineral de hierro reducido previamente DRI por medio de un horno de arco eléctrico EAF, que comprende los siguientes pasos: a. preparar una carga de DRI de mineral de hierro reducido previamente que tiene una metalización superior al 90% y que contiene más de 2.8% en peso de carbono, en donde al menos 80% de dicho carbono se combina con el hierro para formar el carburo de hierro Fe3C, b. cargar la carga de mineral de hierro reducido previamente DRI en el horno de arco eléctrico EAF, c. fundir la carga de DRI para formar hierro fundido líquido; en donde dicho hierro fundido líquido tiene un contenido real predeterminado de carbono, al menos 80% en peso de dicho contenido real de carbono del hierro fundido deriva del carbono en la carga de mineral de hierro reducido previamente DRI y en donde el paso c. se lleva a cabo en una atmósfera reductora y en una cámara de fusión del horno de arco eléctrico EAF sometida a una presión interna positiva generada por los gases producidos por las reacciones de reducción que se desarrollan en el paso c.
