Construction and Application of Digital Twin in Aluminum Electrolysis

The fourth industrial revolution, commonly referred to as Industry 4.0Industry 4.0, with smart manufacturing at its forefront has arrived. This work focuses on the deep integration of advanced digital twinDigital twins technology and traditional aluminium electrolysisAluminium electrolysis technology, involving the overall architecture design, core technological development, and demonstrative application study. A fiveFives-dimensional modelingModeling methodMethod and a standard application framework for aluminum electrolysisAluminum electrolysis are proposed for the first time. The constructed digital twinDigital twins of aluminium electrolysisAluminium electrolysis comprises three levels: electrolysisElectrolysis plant, workshop, and equipment, and is equipped with advanced functions such as real-time monitoringReal-time monitoring, data management, virtual-real mapping, and intelligent decision-making. The engineering applications of digital twinDigital twins technology in aluminium electrolysisAluminium electrolysis have demonstrated its efficacy, producing favourable results in terms of labour downsizing, energyEnergy conservation, and pollution reduction. This research is expected to establish a solid groundwork for the digitalization and intelligent advancement of aluminium electrolysisAluminium electrolysis.
