Abstract

"AGLOMERADOS AUTO-REDUTORES PARA USO NA PRODUçãO DE METAL, MéTODO PARA A PRODUçãO DE AGLOMERADOS AUTO-REDUTORES E APARELHO PARA PRODUçãO CONTìNUA DE AGLOMERADOS AUTO-REDUTORES". São providos aglomerados auto-redutores para uso na produção de metal. Os aglomerados compreendem uma mistura de partículas contendo óxido de ferro e partículas de um agente redutor aglomeradas pelo uso de um pré-gel. Os aglomerados são produzidos por um método e aparelho que dão condições para a mistura e cura dos mesmos. Os aglomerados podem então ser usados para redução dos mesmos para a produção de ferro.
