Abstract: Aiming at reducing energy and carbon consumption and enhancing current efficiency of aluminum electrolysis, a batch of property-modified prebaked carbon anodes prepared in industrial production were applied to 160kA prebaked anode aluminum electrolysis cells in a domestic aluminum company. The industrial statistical data show that, the property-modified anodes can averagely reduce carbon consumption 11.6kg per ton aluminum and energy consumption 106.1kW·h, further more, enhance current efficiency 0.72%. The industrial testing results prove that this kind of new type of prebaked anodes has remarkable effect of saving energy, reducing carbon consumption and enhancing current efficiency of aluminum electrolysis.
Key words: aluminum electrolysis; property-modified prebaked carbon anode; industrial electrolysis test
