摘要
为了降低高炉炉壳表面的温度,增加高炉冷却柱的利用效率,分析了高炉冷却壁上不同冷却水管损坏时安装冷却柱的情况,并优化了其中一种冷却柱的排列布局,同时为了进一步降低冷却壁冷却水管损坏时的炉壳温度,提出了板柱结合的新方法。数值模拟结果表明,当冷却壁上不同冷却水管损坏后,安装冷却柱相比于未安装冷却柱的炉壳表面温度均有明显的下降;通过遗传算法得到的冷却柱排列,使得炉壳表面最高温度为60.9℃、平均温度为48.1℃,相比于工厂未优化的冷却柱排列,炉壳表面最高温度降低了6.8%、平均温度降低了4.1%;板柱结合的炉壳表面最高温度为61.4℃、平均温度为49.7℃,相比于未安装冷却板的排列,最高温度降低了25.2%、平均温度降低了28.1%。本数值模拟研究结果可为冷却壁冷却水管损坏时冷却柱的安装提供理论依据。
In order to reduce the temperature of the blast furnace shell surface and enhance the utilization efficiency of the blast furnace cooling column,the situation of installing cooling columns when the different cooling water pipes on the blast furnace cooling stave were damaged was analyzed,and the arrangement of one of cooling columns was optimized.At the same time,a new method of plate-column combination was proposed to further reduce the temperature when the stave cooling water pipe were damaged.The numerical simulation results show that when the different cooling water pipes on the cooling stave are damaged,the surface temperature of the furnace shell with the cooling column is significantly lower than that without the cooling column.The cooling column arrangement obtained by genetic algorithm makes the maximum temperature for furnace shell surface of 60.9℃ and the average temperature of 48.1℃.Compared with the original arrangement in the factory,the maximum temperature of furnace shell surface is reduced by 6.8%and the average temperature is reduced by 4.1%.The maximum temperature at shell surface of the plate-column combination arrangement is 61.4 ℃,and the average temperature is 49.7℃.Compared with the original arangement without cooling plates,the maximum temperature is reduced by 25.2% and the average temperature is reduced by 28.1%.The numerical simulation results can provide theoretical basis for the installation of cooling columns when the cooling water pipe of the cooling stave is damaged.
