摘要：   摘要： 
针对高炉料面温度难以准确检测的问题，提出一种基于多源信息可信度的高炉料面温度在线检测方法.根据高炉3种异类检测信息的各自特点分别估计料面温度，采用可信度理论通过融合单一信息的估计值计算高炉料面温度.在某钢铁企业2 200 m3高炉应用结果表明，所提出的方法能够准确地检测高炉料面温度，为复杂冶金过程状态检测提供了新的解决思路.

Abstract: Focusing on the difficulty of precisely detecting blast furnace (BF) burden surface temperature, a novel temperature detection method of BF burden surface based on the reliability of multi-source information was proposed.  Firstly, the burden surface temperature is estimated respectively according to the individual features of three kinds of singular heterogeneous information; then the BF burden surface temperature is calculated by fusing the results estimated by the three kinds of singular information based on reliability theory. The application on a 2 200 m3 B F in some steel enterprise shows the method proposed can realize the real-time and precise detection of burden surface temperature, which eventually provides an effective solution for the status monitoring of complicated metallurgy process.  

Key words: blast furnace, burden surface temperature, reliability, information fusion
