Abstract
"MéTODO E EQUIPAMENTO DE PRODUçãO DE FERRO FUNDIDO". A presente invenção relaciona-se com equipamento e método de produção de ferro fundido. O método de produção de ferro fundido inclui as etapas de produzir uma mistura contendo ferro por secagem e mistura de minérios de ferro e aditivos; fazer passar a mistura contendo ferro através de um ou mais leitos fluidizados conectados sucessivamente, de forma que a mistura seja reduzida e calcinada, para, assim, realizar a conversão em material reduzido; formar um leito compactado de carvão, que é a fonte de calor em que o material reduzido foi fundido; carregar o material reduzido para o leito compactado de carvão e suprir oxigênio para o leito compactado de carvão para fabricar ferro fundido; e suprir gás reduzido exaurido do leito compactado de carvão para o leito fluidizado, em que, na etapa de converter a mistura para o material reduzido, o oxigênio é fornecido e combustado diretamente numa área em que o gás reduzido flui para o leito fluidizado. O equipamento para produção de ferro fundido na presente invenção usa este método para a produção de ferro fundido. Através do uso da presente invenção, o gás reduzido que passa através dos leitos fluidizados pode ser melhorado e pode ser impedida a coesão dos finos de minérios que contêm ferro.
