Abstract

"PROCESSO PARA A REDUçãO DIRETA DE MATERIAL DE ALIMENTAçãO METALìFERO". Expõe-se um processo para a redução direta de material de alimentação metalífero. óxidos de ferro são parcialmente reduzidos em um estado sólido em um vaso de pró-redução. Os óxidos de ferro parcialmente reduzidos são fundidos para ferro fundido em um vaso de redução direta que contém um banho de ferro e escória fundidos e é alimentado com um material carbonáceo sólido como uma fonte de redutor e energia e com um gás que contém oxigênio para o monóxido de carbono de pós-combustão e hidrogênio gerados no vaso. A etapa de redução direta gera um gás de saída que contém enxofre e o gás de saída é liberado a partir do vaso de redução direta. Apenas parte do gás de saída liberado a partir do vaso de redução direta é usado na etapa de pré-redução para pré-reduzir os óxidos de ferro no vaso de pré-redução. Somente parte do gás de saída é usado na etapa de pré-redução a fim de controlar a quantidade de enxofre que retorna com os óxidos de ferro parcialmente reduzidos para o vaso de redução direta.
