| Abstract Scope |
In recent years, many smelters have tried various methods to reduce cell voltage, aiming to reduce energy consumption. Lower ACD usually means lower cell voltage. When ACD is reduced to a certain level, the stability of the magnetic fluid becomes a key factor in energy conservation. This paper introduces a transient MHD simulation model for aluminum electrolytic cells. Based on the model, SAMI successfully developed Networked Self-Balancing Busbar Technology to modify and upgrade the busbar system. After applying this technology, the electrolytic cell can resist various random transient disturbances at low ACD, demonstrating strong stability and maintaining high current efficiency. In addition, when one pot experiences current fluctuations, the impact on adjacent pots is significantly reduced. This technology has been applied in several smelters with DC power consumption reduced by 56 kWh/t-Al and current efficiency increased by 0.32%. |
