An expert system based aid for anode production at an aluminium smelter

TL;DRAbstract

In the smelting of aluminium, a high current is passed between an anode and a cathode across a molten bath of electrolyte. As the anode is consumed in the electrolytic process, the manufacture of anodes represents a high operational cost. Better control of the anode production process could lead to a reduction in the variability of anode qualities, improved anode performance and a resulting longer anode life with a concomitant reduction in operational costs. The production process of anodes is controlled by operators through a Supervisory Control and Data Acquisition (SCADA) system that continuously polls the front line program logic control of the anode plant. Information relating to potential problems or causes of existing problems is available, which an experienced operator can obtain by querying the SCADA system. As there is too much data for the operator to assimilate to properly control the process, the operator tends to rely on the control system itself to control the process wi
