Abstract Scope Since 1996, Shenyang Aluminum and Magnesium Engineering and Research Institute Co. Ltd. (SAMI) has developed a series of aluminum reduction technologies for prebaked anodes potlines, the SY series, ranging from 160kA, 190/200kA, 230/240kA 280kA, 300kA, 350kA to 400kA. In 2009, SAMI developed the 500kA reduction technology called SY500, and since then has been continuously improving this technology, and has applied it in the engineering of new aluminum smelters. The paper introduces the development of the first, second and third generation SY500 potline technology, systematically analyzes breakthroughs of new technologies adopted by SY500 potline technology, such as the New Conceptual Cathode Technology (NCCT), New Conceptual Busbar Technology (NCBT), Network Busbar Technology (NBT), etc. The SY series potline technology has been validated for its excellent technical and economic performances and become the most widely used new aluminum reduction technology in the world.
