Abstract

"INSTALAçãO DE REDUçãO DIRETA PARA PRODUZIR METAL FUNDIDO A PARTIR DE UM MATERIAL DE ALIMENTAçãO METALìFERO". Expõe-se uma instalação de redução direta para produzir metal fundido a partir de um material de alimentação metalífero. A instalação inclui um vaso de redução fixo para conter um banho de metal e escória fundidos e um espaço de gás acima do banho. A instalação também inclui uma disposição para suprir materiais de alimentação sólidos e gasosos ao vaso e para sangrar material fundido proveniente do vaso. A instalação também inclui pelo menos duas plataformas para suportarem operadores da instalação a alturas diferentes do vaso. A disposição de corrida de metal e a disposição de corrida de escória ficam localizadas de forma a serem acessíveis para os operadores de instalação em uma plataforma de casa de corrida e a disposição de corrida de metal final e a disposição de corrida de escória final ficam localizadas de forma a serem acessíveis pelos operadores da instalação em uma plataforma de corrida final que fica a uma altura mais baixa do que a plataforma de casa de corrida.
