| Abstract Scope |
After successful implementation of NCCT+ Cell Technology, SAMI and China SPIC Inner Mongolia Branch cooperated to select 5 pots in 350kA potline of Huomeihongjun Aluminum smelter for low carbon emission experiment. Based on the evaluation of original performance, lining (NCCT+), busbar configuration (NSBT), pot shell, and superstructure of the test pots are upgraded, and the anode current distribution monitor system is also configured. After upgrading, the stability of MHD including magnetic field value and uniformity have been significantly improved by more than 50%, and ultimate ACD, metal horizontal current, CVD and the busbar voltage drop are also reduced obviously. Accompanied by the application of 15cm low metal height management technology, the half year excellent performance at 366 kA with 94.6 % current efficiency and net specific energy consumption of ＜12180 kWh/t-Al has confirmed that the technology upgrading has achieved prominent carbon reduction and economic benefits. |
