Abstract

"MéTODO PARA CONTROLAR UMA CéLULA DE REDUçãO DE ALUMìNIO COM áNODOS PRé-COZIDOS". No método para controlar uma célula de redução de alumina com ânodos pré-cozidos uma área de concentração reduzida de alumina é definida na célula medindo os valores presentes de corrente elétrica em pelo menos um ânodo da célula independentemente de outros ânodos. Com a detecção da redução de corrente elétrica neste ânodo, a taxa de alimentação de alumina é aumentada em um banho da célula na área de concentração reduzida de alumina."METHOD FOR CONTROLING AN ALUMINUM REDUCTION CELL WITH PRECOOKED ANODS". In the method for controlling an alumina reduction cell with pre-cooked anodes a reduced alumina concentration area is defined in the cell by measuring present values of electric current in at least one cell anode independently of other anodes. By detecting the reduction of electric current at this anode, the alumina feed rate is increased in a cell bath in the reduced alumina concentration area.
