Abstract

"MéTODO PARA PRODUZIR FERRO METáLICO". Quando uma mistura contendo uma fonte de óxido de ferro e um agente redutor carbonáceo é aquecida e reduzida para fabricar ferro metálico, carbonetação e fusão do citado ferro metálico sólido produzido por aquecimento e resfriamento são progredidas eficientemente tal que partículas de ferro metálico possam ser fabricadas eficientemente sob alta eficiência de energia térmica. Um método para aquecer, reduzir e fundir uma mistura de matéria prima contendo agente redutor carbonáceo e uma substância contendo óxido de ferro para fabricar ferro metálico, caracterizado em que uma fração líquida em fases sólida e líquida coexistentes de escória produzida contendo uma ganga de multi-componentes é controlada para assim acelerar a fusão de ferro metálico sólido produzido.
