Abstract
Due to the continuous uprising trend in raw material prices, Aluminium-LME meltdown, and consequent shrinking profitability margins, low amperage smelters are facing many challenges. To overcome the challenges a path defining initiative has been undertaken to bring down the specific power consumption and to improve productivity. To meet this objective, we earmarked ten pots for a pilot study. A Booster-Rectifier dedicated for these ten pots was installed. Some measures were taken, such as: change in busbars system, change in anodes dimensions, change in anode ring, larger cathode blocks and collector bars, new lining, increased current, and use of PLC pot controllers. This approach has not only the potential to consolidate the business viability of our operations, but also the outcome of this R&D can be accommodated in any other smelter of world. This paper will discuss the performance of ten new modified pots, benefits in voltage drop and way forward.
