摘　　要：建立了高炉铸铜冷却壁的有限元模型,确定了冷却壁温度场模拟的初始条件和边界条件。利用有限元软件ANSYS Workbench对高炉铸铜冷却壁进行稳态传热分析。结果表明,在没有渣皮的恶劣工况下,铸铜冷却壁镶耐火砖处、冷却壁本体、铜管的最高温度分别为956.23、254.33、87.02℃,铸铜冷却壁的最大热流密度为17.507×105 W/m2,满足工况使用需求。当冷却水管与冷却壁本体熔合率为80%时,铸铜冷却壁也能正常使用,但是冷却性能略有降低。A finite element model for blast furnace cast copper stave was established, and the initial and boundary conditions of temperature field simulation were determined. By means of finite element soft- ware ANSYS Workbench, the steady heat transfer analysis of blast furnace cast copper stave was carried out. The results show that in severe case of the without slag-film, cast copper stave has the highest tem- perature in the site of inserting firebricks,reaching 956.23 ℃. The maximum temperature of cast copper stave body and copper tubes enbeded in stave are 254.3 ℃ and 87.02 ℃, respectively. The maximum heat flux density of cast copper stave is 17. 507×105 W/m2 , meeting the needs of working conditions. When the fusing rate reaches 80% between the stave body and the bedded copper tubes, it can also be used normally, while cooling performance is deteriorated slightly.
