Abstract

equipamento de produção de ferro fundido. um equipamento para a produção de ferro fundido de acordo com uma modalidade exemplificativa da presente invenção inclui: i)pelo menos um reator de redução de leito fluidizado, que reduz e plastifica o minério de ferro e converte o minério de ferro em materiais reduzidos, ii) um fusor-gasificador, em que é carregado minério reduzido e é injetado oxigênio, produzindo o fusor-gasificador ferro fundido e iii) uma linha de suprimento de gás de redução, que fornece um gás de redução descarregado a partir do fusor-gasificador para o reator de redução de leito fluidizado. o reator de redução de leito fluidizado inclui um ciclone que está instalado no reator de redução de leito fluidizado para coletar finos de minério de ferro. um injetor de gás, que impede que os finos de minério adiram por injeção de gás contendo carbono, é conectado ao ciclone.
