摘要：

为解决铝合金自动锻造生产线低温环境下脱模剂喷涂量过小甚至无法喷涂的问题，对喷涂失效原因进行了分析。介绍了铝合金自动锻造生产线喷涂系统的结构原理，构建了脱模剂的流体数学模型，分析了喷涂系统的各项参数对喷涂流量的影响。实验测量了不同温度下铝合金锻造专用HYKOGEEN AL 2931 MBA型号脱模剂的运动黏度，建立了黏温方程。计算得到了所研究的自动锻造生产线工艺条件下的脱模剂温度与喷涂流量的关系，揭示了喷涂失效的根本原因，为温度过低导致脱模剂运动黏度增大导致的。提出了应将脱模剂的温度控制在20 ℃以上，并针对生产线进行改进的措施，取得了良好的效果。

In order to solve the problem that the amount of release agent spraying was too small or even impossible to spray under the low temperature environment for the aluminum alloy automatic forging production line, the causes for spraying failure were analyzed. Then, the structure principle of spray system for the aluminum alloy automatic forging production line was introduced, and the fluid mathematical model of release agent was established to analyze the influences of various parameters for the spray system on the spray flow rate. Furthermore, the kinematic viscosity of HYKOGEEN AL 2931 MBA release agent for aluminum alloy forging at different temperatures was measured by the experiment, and the viscosity-temperature equation was established. Finally, the relationship between release agent temperature and spray flow rate under the studied process conditions of the automatic forging production line was calculated, and it was revealed that the root cause of spraying failure was the increase in the kinematic viscosity of release agent caused by too low temperature. The measures to control the temperature of release agent to be above 20 ℃ and to improve the production line are put forward which achieve good results.
