Abstract

"FORNO ELéTRICO DE REDUçãO". A presente invenção se refere a um forno elétrico de redução (1) para executar processos de redução, em particular, para a redução de escória para a recuperação de componentes metálicos. Este forno trabalha com energia elétrica aportada no interior do forno (01) por meio de pelo menos um eletrodo. Neste contexto, o forno de redução (1) apresenta, construída de maneira estanque ao ar, uma abertura para carregamento (3) para o material a ser carregado, que é transportado por um dispositivo de carga (4) , sendo que a abertura para carregamento serve simultaneamente também como abertura para exaustão do gás (3) gerado durante o processo.
