Abstract

"MéTODOS E EQUIPAMENTO DE PRODUçãO DE FERRO FUNDIDO". Método e equipamento para fabricar ferro fundido incluindo produzir material de redução de finos de ferro reduzido direto e aditivos calcinados misturados, sendo o material de redução produzido a partir de leitos fluidizados múltiplos; carregando o material de redução em pelo menos um par de prensas de rolete; comprimindo com roletes o material de redução através de um par de prensas de rolete para produzir material compactado contínuo tendo ranhuras formadas nas superfícies comprimidas; esmagando o material compactado; carregando o material compactado triturado num leito compactado de carvão; e suprindo oxigênio para o leito compactado de carvão para fabricar ferro fundido, em que, na produção do material compactado, o material compactado é formado de tal maneira que são formados ângulos agudos e obtusos entre uma linha central formada ao longo de um comprimento de uma seção reta que é cortada ao longo de uma direção longitudinal perpendicular a uma direção axial das prensas de rolete e linhas de conexão que conectam ranhuras mais próximas uma ã outra através da área da seção reta. Um equipamento para a produção de ferro fundido executa o método acima para o fabrico de ferro fundido. Os processos envolvidos na produção de ferro fundido que usam a presente invenção são convenientes, eficientes e atuam de forma a melhorar a produtividade e permitem maior flexibilidade com respeito à operação do equipamento durante a produção do material compactado.
