摘　　要：水泥回转窑是新型干法水泥生产流程中的核心设备。窑筒体的表面温度可以综合反映窑内状况,因此对回转窑筒体的表面温度进行实时监测是保障回转窑安全运行的重要手段。为了有效表达温度分布状况,对回转窑筒体表面温度的三维热图像生成方法进行了研究。采用灰度级-伪彩色映射模型将不同温度映射成了不同颜色,并创新性地通过结合OpenGL技术实现了三维热图像颇具真实感的实时呈现。现场测试结果表明,基于此方法生成的回转窑筒体表面的三维热图像具有表达直观、运行稳定可靠等特点。A rotary cement kiln is the core equipment in the production process of dry cement.The surface temperature of a rotary kiln can reflect the internal status of the rotary kiln.Therefore,to monitor the surface temperature of the rotary kiln in real time is very important for keeping the safe operation of the rotary kiln.To express the temperature distribution of the rotary kiln effectively,the threedimensional thermograph generation of the surface temperature of the rotary kiln is studied.A pseudogray color coding model is used to map different temperatures into different colors.By incorporating an OpenGL technology creatively,realistic three-dimensional thermographs are displayed in real time.The in-situ test results show that the three-dimensional thermographs of the rotary kiln surface generated have the features of intuition,stability and reliability.
