| Abstract Scope |
There are lots of repetitive measurements in daily operation and management in aluminum reduction cells. The pot controller takes the whole pot as a single "point" for cell voltage and alumina concentration control. With the continuous increase of pot size and capacity, the gradients of anode cathode distance (ACD), alumina concentration, bath temperature and super heat become a non-negligible problem. This problem seriously restricts the improvement of the digital and intelligent level of aluminum electrolysis. This paper developed a ‘Digital Monitoring and Intelligent Control System’ (DM&IC), expended online monitoring parameters from traditional pot voltage and current to 65 new digital parameters, including pot voltage, pot current, anode current distribution, bath temperature, metal level, bath level and 12 cathode voltage drops. The accuracy of these parameters meets the needs of daily operation and management. The automatically measured parameters were deeply mined for valuable information and applied them for new intelligent control, including local alumina control, anode effect detection and termination, and management parameters prediction. Then an industrial trial was carried out for 6 months in a smelter. |
