      Material and energy double balance control technology with low cell voltage and its six-year plant practice were introduced. The concentration of Al2O3 in aluminum cell is smoothly and steadily controlled at 1.5%~2.5% with application of real-time Al2O3 concentration controlling technology. The energy balance of aluminum cell is ensured by real-time control of cell voltage and automatic addition of AlF3.
