METHOD OF CONTROLLING ALUMINUM REDUCTION CELL WITH PREBAKED ANODES

摘要

In the method of controlling an aluminum reduction cell with prebaked anodesanarea of reduced alumina concentration is defined in the cell by measuring thepresentelectrical current values in at least one anode of the cell independently ofother anodes.Upon detection of the electric current reduction in this anode, the rate ofalumina feedingis increased into a bath of the cell at the area of reduced aluminaconcentration.
