Abstract

"CéLULAS FUNDIDAS DE ALUMìNIO APERFEIçOADAS USANDO ANODOS INERTES". A presente invenção refere-se a células convencionais de fundição de alumínio (1)são substituídas por conjuntos de anodo inerte (12)que substituem os anodos de carbono consumíveis (2)da célula (1). Os conjuntos de anodo inerte (12)podem incluir múltiplos anodos inertes e também podem incluir isolamento (18)para reduzir a perda de calor durante a operação de células de substituição (10).
