Abstract

Patente de Invenção: <B>"PROCESSO DE PRODUçãO DE FERRO-GUSA LìQUIDO OU PRé-PRODUTOS DE AçO LìQUIDO"<D>. Em um processo de produção de ferro-gusa líquido ou pré-produtos de aço líquido a partir do material contendo óxido de ferro, material contendo óxido de ferro de finas partículas é reduzido para ferro-esponja de partículas finas pelo processo de leito fluidizado de um gás redutor em pelo menos um estágio de redução de leito fluidizado (7, 8) e minério grumoso é reduzido para ferro-esponja grumoso em um estágio de redução de leito fixo (28). O ferro-esponja é carregado em uma zona de fusão-gaseificação
