摘要熟料游离氧化钙（f-CaO）含量是水泥质量控制重要指标，由于该指标目前无法实现在线实时检测，难以建立有效的水泥烧成系统闭环控制。在常规控制方案基础上，提出了一种基于中子活化分析仪对水泥生料入窑成分实时检测，进而利用神经网络算法构建游离氧化钙软测量模型，利用TaiJi-MPC软件实现对水泥烧成系统的风、煤、料的卡边控制方法。该方法可以降低f-CaO标准差波动约10%，提高f-CaO指标含量>0.3%，经济效益和社会效益显著。

Abstract: The content of free calcium oxide (f-CaO) in clinker is an important index for cement quality control. As this index cannot be realized in real-time detection online at present, it is difficult to establish effective closed-loop control of cement kiln system. Based on the conventional control scheme, a method is proposed to detect the raw materials of cement kiln components in real time based on neutron activation analysis, and then use neural network algorithm to build a soft measurement model of free calcium oxide. The TaiJi-MPC software is used to realize the method of edge control of gas, coal and meal in cement kiln system. This method can reduce the standard deviation fluctuation of f-CaO by about 10%, increase the content of f-CaO by more than 0.3%, and significantly improve economic and social benefits.

Key words: kiln system edge control TaiJi-MPC soft measurement neutron activation analysis
