| Abstract: | For solving the problems of high voltage, temperature and energy consumption of 190kA PB cell, the bath composition and technological parameters such as cell voltage and bath temperature have been re-adjusted. After re-adjustment, cell voltage has been reduced to 4.11V, bath ratio to 2.5, bath temperature to 950℃, while current efficiency has been increased to 93.7%. As compared to the previous indices, DC energy consumption for per tonnage of aluminum has been reduced by 1173kWh/t. The practice has shown that low-voltage operation of large prebaked cells is feasible. In this paper, the methods for adjustment of bath composition and temperature and cell voltage are presented. |
