Abstract

Un método para producir ferroaleación líquida mediante procesamiento directo de compuestos de hierro portando manganeso y cromo, mediante los pasos de: mezclar el reductor carbonáceo, agente de flujo y un ligante con materiales tales como arenas de hierro, óxidos metálicos, concentrados de mineral de manganeso- hierro y/o concentrados de mineral de cromo-hierro y arenas de sílice, para formar una mezcla; formar aglomerados a partir de la mezcla; alimentar los aglomerados a un horno de fusión con otros materiales; fundir los materiales de alimentación a una temperatura desde 1500 hasta 1760 °C y formar una escoria y metal caliente; remover la escoria; y tomar el metal caliente como ferroaleación líquida.
