Abstract: The current advances in the systematic energy saving-oriented monitoring and simulation technologies of metallurgical processes, including the research and application of energy management system, numerical simulation method in metallurgical processes, are reviewed. The process simulation of metallurgical processes, computational fluid dynamics (CFD) simulation of key metallurgical equipment and their integration are mainly analyzed, and the application and limitation of numerical simulation technology for systematic energy saving of metallurgical processes discussed. The results show that the process simulation can analyze parameter variation of a whole metallurgical production process, while ignoring physical characteristics of the unit operation and space changes. CFD simulation can be used to analyze the mechanism and optimize the operating parameters of single metallurgical equipment, however it can not realize the relevance of operating parameters between upper and lower processes. The integration of process and CFD simulations by using time series method can combine the advantages of both, which will be an important direction in investigation of the systematic energy saving of metallurgical processes.
