Abstract
"MéTODO PARA MELHORAR A VELOCIDADE DE PRODUçãO DE FERRO EM ALTO-FORNO". A presente invenção relaciona-se com método para melhorar a velocidade de produção de ferro num alto-forno que seja carregado com aglomerados que contêm ferro. O método compreende fazer contatar o material carregável que contém ferro com uma quantidade efetiva modificadora da escória de uma dispersão de um material particulado, em que o referido contato ocorre antes do carregamento do aglomerado no processo do alto-forno.
