Abstract

"PROCESSO DE REDUçãO DIRETA DE MINéRIOS". Trata-se de um processo de redução direta e de um vaso metalúrgico fixo, isto é, não-rotativo, destinados à produção de metais a partir de um material de alimentação metalífero. O processo consiste de um processo que tem como base o banho em fusão, o qual inclui a injeção de materiais de alimentação sólidos com um gás carreador, dentro do banho em fusão, via uma ou mais lança/ventaneira descendentemente estendidas (11) e faz com que o gás escoe a partir do banho em fusão, em uma taxa de fluxo de ao menos 0,30 Nm^ 3^/s/m^ 2^, na interface existente entre a camada de metal
