铝挤压工艺能耗高、热量损失严重，挤压机的工作效率不高是主要因素，以10 MN铝挤压机为研究对象，针对挤压过程液压系统进行能耗建模：分析系统的能量传输、能量转换及能量消耗，总结出关键的耗能元件，并给出相应的理论能耗公式；利用AMESim软件建立仿真模型，证明了模型的正确性，分析了挤压过程各元件的能耗曲线，结果表明溢流损失是主要的能量损失方式，这对于挤压机的节能优化具有理论指导意义。

A problem of high energy consumption and serious heat loss exists in the aluminum extrusion process and the main factor is the inefficiency of the extruder.The study was based on 10MN extruder.Energy consumption model was established about the hydraulic system in the extrusion process.The energy transmission,conversion and consumption were analysed. the key components of energy consumption were summarized and the theoretical formulas of Energy consumption were also presented. Using AMESim software to establish the simulation model and the validity of the model was proved .Then energy curves was analysed in the extrusion process.The results indicated that the mainly energy loss came from overflow losses,which have theoretical significance for energy-saving and optimize design of extruder.
