Abstract

método e dispositivo para produzir metal reduzido direto. trata-se de método para produzir material de metal reduzido direto que compreende as etapas de: a) carregar material de metal a ser reduzido em um espaço de fornalha (120); b) evacuar uma atmosfera existente do espaço de fornalha (120) de modo a alcançar uma subpressão dentro do espaço de fornalha (120); c) fornecer, em uma etapa de aquecimento principal, calor e gás hidrogênio ao espaço de fornalha (120), de modo que gás hidrogênio aquecido aqueça o material de metal carregado a uma temperatura alta o suficiente de modo que óxidos de metal presentes no material de metal sejam reduzidos, fazendo, por sua vez, com que o vapor d?água seja formado; e d) condensar e coletar o vapor d?água formado na etapa c em um condensador (160) abaixo do material de metal carregado; a invenção é caracterizada pelo fato de que o dito gás hidrogênio na etapa c ser fornecido sem recirculação do gás hidrogênio, e pelo fato de que o método compreende adicionalmente a etapa realizada de modo subsequente de remover o material de metal reduzido do espaço de fornalha (120) e armazenar e/ou transportar o material de metal reduzido sob uma atmosfera inerte.
