Abstract

"DISPOSIçãO DE ELETRODO COMO FUNDO SUBSTITTUTO DE UM FORNO DE FUSãO DE ESCóRIA ELETROTéRMICO". A disposição do eletrodo usa eletrodos (4) orientados verticalmente com contatos da parede lateral (7) de um forno de fusão eletrotérmico (1) para produção de alumínio. Os contatos da parede lateral (7) podem ser movidos radialmente no forno (1) para compensar o desgaste dos contatos. Os contatos da parede lateral (7) podem ser ocos para permitir que uma carga de formação de escória seja alimentada no forno (1).
