Abstract
"PROCESSO E APARELHO PARA PRODUZIR FERRO REDUZIDO". Na produção de ferro reduzido por aglomeração de um pó misto de um material ferrífero e um agente redutor para formar compactos como briquetes ou pelotas, e redução dos compactos em uma atmosfera de alta temperatura, quando a temperatura dos compactos reduzidos é de 900°C ou mais alta, o teor de óxido nos compactos reduzidos é ajustado a 11% ou mais, e a basicidade dos compactos reduzidos é ajustada a 0,5 ou mais alta.
