摘要
建立了高炉铜冷却壁非稳态传热分析模型,利用ANSYS单元生死技术模拟了冷却壁表面的渣皮再生行为,分析了渣皮脱落后的生长规律及壁体温度和热负荷的变化过程。结果表明,渣皮生长遵循幂函数规律。经过计算,渣皮脱落0.9 min时铜壁测量点温度达到最高值59℃,经过23.5 min趋于稳定。铜冷却壁承受的最高热负荷为107.8 kW/m2,热面最高温度达到123℃。
The unsteady-state heat transfer model on BF copper stave was established.Based on the element birth and death technology of ANSYS,recovery behavior of slag skull on the stave surface was simulated.The growth rhythms of slag skull,as well as the changing process of stave temperature and heat load were analyzed.The results show that slag skull growth follows the power function.On the analysis condition,the measuring point of copper stave reaches maximum temperature 59℃ at the time 0.9min after slag skull dropped off.After 23.5min,the stave temperature got steady.The maximum heat load is 107.8kW/m2.The maximum temperature on the hot face of copper stave reaches 123℃.
