The deep integration of intelligent manufacturing and traditional aluminum electrolysis technology lead the sustainable development of aluminum electrolysis industry. At present, the lack of effective mapping between physical equipment and data models hindered the pace of intelligent transformation of aluminum electrolysis industry. Herein, combining digital twin technology and aluminum electrolysis technology, the architecture of digital twin in aluminum electrolysis was designed, the key technology and application were researched and developed. This study constructed a five-dimensional model of physical entities, virtual models, twin data,intelligent decision services, and interactive connection. Physical entities of aluminum electrolysis were divided into three levels: plant, workshop and equipment. Through scene modeling, physical field modeling and dynamic simulation modeling, the virtual models corresponding to the physical entities were mapped. Synchronized twin data between physical entities and virtual models was realized by interactive connection technology. The deployed prototype system of digital twin realized the virtual-real mapping of aluminum electrolysis production, and provided advanced ideas and technical methods for the digital and intelligent transformation of aluminum electrolysis industry.
