基于ANSYS的高炉铸铜冷却壁稳态传热分析
|
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 software 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 temperature 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.
