Abstract

"MéTODO PARA PRODUZIR FERRO METáLICO GRANULAR; MéTODO PARA PRODUZIR UM AçO FUNDIDO; DISPOSITIVO PARA ALIMENTAR CADINHO". A presente invenção é dirigida a um método para produzir ferro metálico granular, incluindo: aquecer uma matéria prima formada compreendendo um agente redutor carbonáceo e uma substância contendo óxido de ferro em um forno de fusão de redução para submeter o óxido de ferro contido na matéria prima formada a redução em estado sólido; e cementar ferro reduzido resultante da redução em estado sólido com carbono contido no agente redutor carbonáceo para fazer o ferro reduzido fundir, enquanto separando para fora componentes de ganga contidos na matéria prima formada e fazendo o ferro metálico fundido resultante coalescer em ferro metálico granular, onde uma gás atmosférico presente na proximidade da matéria prima formada na etapa de cementação e fusão tem um grau de redução não menor que 0,5. A presente invenção também é dirigida a um método para produzir ferro metálico, incluindo formar uma camada de depósito contendo escória produzida no processo de fusão de redução em refratários do cadinho, protegendo assim os refratários do cadinho enquanto produzindo o ferro metálico. A presente invenção é adicionalmente dirigida a um dispositivo para fornecer uma matéria prima auxiliar a um cadinho de um forno de fusão de redução do tipo de cadinho móvel adaptado para produzir ferro metálico, o dispositivo incluindo um duto de suprimento conectando-se verticalmente com uma porção de teto do forno.
