Abstract
"MéTODO DE MANUFATURA PARA FERRO METáLICO GRANULADO COM BAIXA CONCENTRAçãO DE ENXOFRE". As quantidades de uma substância que contém CaO, uma substância que contém MgO, e uma substância que contém SiO~ 2~- contidas em uma mistura de matéria prima, são ajustadas de maneira tal que a operação de manufatura é realizada com basicidade de escória (CaO + Mg0) /SiO~ 2~ de 1,3 a 2,3, e com a concentração de MgO de 5 a 13% em massa quanto à composição de escória, que são dependentes da concentração de cada um de CaO, MgO e SiO~ 2~, contídos na mistura de matéria prima. Isto proporciona um método de manufatura para ferro granulado de alta qualidade com baixa concentração de enxofre, em que uma mistura de matéria prima que contém uma substância que contém óxido de ferro tal como minério de ferro e um agente redutor carbonífero tal como um material de carbono são submetidos a redução e fusão com um forno de redução do tipo de cadinho móvel enquanto se suprime a concentração de enxofre tanto quanto possível, gerado no ferro metálico granulado, particularmente devido ao material de carbono, tal como carvão.
