摘要
从冶金企业能源管理系统的研究和应用现状、冶金过程的数值模拟方法与应用等方面,综述了基于系统节能的冶金过程监测与模拟技术的研究进展,分析了冶金工艺流程的过程模拟技术、冶金关键设备的计算流体力学(CFD)模拟技术及两者集成的研究现状以及数值模拟技术在冶金过程系统节能中的应用与不足之处.结果表明,过程模拟技术可分析冶金工艺整体生产流程的参数变化,但忽略了操作单元物理特性、空间变化等因素;CFD模拟可分析单个冶金设备运行机理和优化工艺参数,但不能实现上下工序之间操作参数的关联.采用时间序列方法集成过程模拟与CFD模拟技术可综合两者的优点,是研究冶金过程系统节能研究的重要方向.
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.
