Under the dual background of"emission peak,carbon neutrality"and stepped electricity price policy,it has become the"lifeline"for the sur-vival and development of aluminum companies to reduce the power consumption per ton of aluminum through technological upgrading.The 350 kA series aluminum reduction cells of a domestic company have been optimized and upgraded in terms of the cell lining with SAMI's energy-saving technology,a-chieving an energy-saving effect of reducing the DC power consumption by 321 kWh/t-Al.After the wide promotion,it is expected to save power by a-bout 112 million kWh annually and reduce CO2 emission by about 65 000 tons annually.
