针对梅山３＃ 高炉炉底条件，用有限元素法开发了只依靠热电偶测得的温度作为边界条件和修正温度，对炉底侵蚀情况进行在线监测的二维数学模型，解决了采用炉底及炉侧的对流边界条件难以实时检测的问题－ 模型中采用网格变形拟合的方法处理边界移动的问题，算法简单便于在线运行－ 通过梅山３ ＃ 高炉的实际应用及对不同侵蚀状态的计算，结果是令人满意的
According to the condition of bottom of Meishan No.3 blast furnace, finite element method was used to develop a two-dimensional mathematical model for on-line monitoring of furnace bottom erosion by using the temperature measured by thermocouple only as boundary condition and temperature correction, Difficulties in Real-time Detection of Convection Boundary Conditions on the Furnace Side - The Problem of Boundary Movement Treated by Mesh Transformation Fitting in the Model, Simple and Convenient Online Operation - Through the practical application of the Meishan No.3 blast furnace and the calculation of different erosion states, The result is satisfactory
