Abstract

En el método para controlar una celda de reduccion de aluminio con ánodos precocidos se define en la celda un área de concentracion de alumina reducida mediante la medicion de los valores de la corriente eléctrica presente en al menos un ánodo de la celda independientemente de otros ánodos. Tras la deteccion de la reduccion de la corriente eléctrica en este ánodo, se aumenta la tasa de alimentacion de alumina dentro del bano de una celda en el área de concentracion de alumina reducida.In the method for controlling an aluminum reduction cell with pre-cooked anodes, a reduced alumina concentration area is defined in the cell by measuring the values of the electric current present in at least one anode of the cell independently of other anodes. After the detection of the reduction of the electric current in this anode, the rate of feeding of alumina within the bath of a cell in the area of concentration of reduced alumina is increased.
