Abstract
"MéTODO DE GRANULAçãO DE MATERIAL DE SINTERIZAçãO PARA FABRICAR FERRO". é um objeto da presente invenção fornecer um método de granulação de matéria-prima para sinterizar, para a fabricação de ferro, o qual é eficazmente usado para granular matéria-prima para sinterizar, para a fabricação de ferro, tal como finos de minérios de ferro, na fabricação de minério sinterizado que forma as matérias-primas para uma carga de alto-forno em um processo de produzir ferro gusa, e tornar possível melhorar suficientemente a produtividade de uma máquina de sinterização. A presente invenção é dirigida a um método de granulação de um material de sinterização para fabricar ferro contendo minério de ferro em pó, compreendendo um processo para realizar a granulação por diluição preliminar das partículas finas tendo um tamanho médio de partícula de não mais do que 200 <109>m em uma porção de um solvente ou um material de sinterização, e adição do material resultante ao restante do material de sinterização, em que referida granulação é pelo menos um processo selecionado do grupo consistindo dos seguintes (1), (2) e (3): (1) um processo para realizar a granulação, o qual compreende Misturar referidas partículas finas com água, de modo a formar uma lama tendo uma viscosidade de 0,005 a 10 Pa.s, e depois adicionar a lama ao material de sinterização, (2) um processo para realizar a granulação, o qual compreende granular preliminarmente referidas partículas finas com 13 a 60 % em quantidade de massa de um material de sinterização compreendendo minério de ferro como um componente essencial medido no estado seco, e depois adicionar referido produto granulado ao restante do material de sinterização, e (3) um processo para realizar a granulação, o qual compreende misturar preliminarmente referidas partículas finas com 0,3 a 10 % em quantidade de Massa do material de sinterização, medido no estado seco.
