针对高炉炉墙结构复杂，铜冷却壁热面工况难以直接检测的问题，采用有限元分析技术，建立高炉炉腰下部区域炉墙三维稳态传热模型，并对不同工况下炉墙温度场分布进行仿真。通过结合仿真结果和现场可检测数据，不断修正热面边界条件，推算出铜冷却壁热面挂渣厚度，为高炉操作提供必要的信息和可靠的指导。
針對高爐爐牆結構複雜，銅冷卻壁熱麵工況難以直接檢測的問題，採用有限元分析技術，建立高爐爐腰下部區域爐牆三維穩態傳熱模型，併對不同工況下爐牆溫度場分佈進行倣真。通過結閤倣真結果和現場可檢測數據，不斷脩正熱麵邊界條件，推算齣銅冷卻壁熱麵掛渣厚度，為高爐操作提供必要的信息和可靠的指導。

The structures of blast furnace wall are complex and the hot surface conditions of copper stave are difficult to test directly. To solve the problems, finite element analysis technique is used to build three dimensional steady heat transfer model of low part of the belly of blast furnace. And the temperature field distributions of blast furnace wall under different conditions are simulated. By combining the simulation results and the test data, and correcting the boundary conditions of hot surface, the thickness of slag skull of copper stave can be estimated, thus providing the necessary information and reliable guidance for the operation of the blast furnace.
