Applications of new structure reduction cell technology in Chalco's smelters

A new generation of key energy saving technology for aluminum reduction has been implemented by Chalco. A new structure aluminum reduction cell technology has been successfully developed by Chalco and is now widely applied in several of Chalco's smelters. This new structure includes key technologies such as the new specially designed cathode installation, a heat preservation lining and a low voltage operation control system. The molten metal fluctuation that is driven by the great magnetic field is greatly restrained in the cells, based on reducing the anode to cathode distance (ACD) without any loss of current efficiency. This realizes a lower energy consumption and less GHG emissions. The industrial tests and applications of this technology have been carried out successfully in the various scale aluminum reduction cells in Chalco's smelters and about 12000 kWh of DC consumption per ton of aluminum and 3.70-3.75 V of cell voltage have been achieved.
