Abstract：Blast furnace longevity has become an important part of the progress of modern ironmaking technology. Improving furnace cooling equipment life is one of the key factors to ensure the longevity. To figure out the damage cause to the stave-plate compound cooling system and provide effective guidance for the optimal design of cooler structures and safe production，a fluid-thermal-structural coupling model was developed according to the actual size. Based on the heat transfer theory and the finite element numerical simulation，the distribution characteristics of flow field，temperature field and stress field were analyzed. Combined with the actual case of blast furnace，the essential reasons of the damage were systematically studied and the specific damaged parts were pointed out. The accuracy of the simulation analysis results is verified by the real-time recorded temperature data of a commercial blast furnace. The results show that the front two sides of the cooling plate and laminar sublayer in the water pipes are the weak link of the cooling system. Under the same condition，the temperature in the front two sides of the cooling plate is higher than that of other parts at 4.5 ℃. The deformation of the front end of the cooling plate is the largest，reaching 2 mm. The main reasons for the breakage of the cooling plate is the frequent falling of the slag skin caused by the large fluctuation of the coke quality M10 and M40 index in the production of the blast furnace.
