Modelling and Design of the Cathode Block Assembly Using Different Types of Models

In the push to improve key performance indicators (KPIs) of existing smelters, Hall-Héroult cellCell retrofits projects are getting very popular especially in China. The cathode assemblyCathode assembly is a prime candidate for redesign as it is possible to reduce the cathode voltage dropCathode voltage drop (CVD) and the metal pad horizontal current at the same time leading to a reduction of the cellCell energyEnergy consumption. A new cathode assemblyCathode assembly design concept developed by Elkem is being investigated in the current work using three types of complimentary models. The results are presented and compared in this paper.
