The Pot Technology Development in China
Starting from 1996, the Shenyang Aluminium & Magnesium Engineering & Research Institute (SAMI) developed a series of prebaked pot technologies ranging from 160kA, 190/200kA, 230/240kA 280kA, 300kA, 350kA to 400kA pots. All of them have been applied to the industry field, which gives rise to total capacity of 12Mt of aluminium. These pot technologies were developed through effective numerical simulation modelling and by learning the success and failure of the engineering and operation of previous pot technologies. Numerical modelling, pot design, pot measurements and process control will be described in this article. The SY series pot technology has been validated for its technical performance and economy. SAMI is launching a new campaign to reduce more investment and improve pot performance.
