摘要
讨论了实现高炉铜冷却壁冷却系统自保护能力的两个方面:挂渣能力和挂渣环境.在编制通用三维冷却壁传热计算软件的基础上,通过对实际铜冷却壁进行计算并结合高炉实际操作经验分析得出:铜冷却壁更适合应用在高炉的高热负荷区;铜冷却壁具备很好的挂渣能力,但在高炉生产过程中实现冷却系统的“自保护”能力以达到长寿高效,还必须提供好的挂渣环境.分析了挂渣环境的诸因素,给出了煤气温度变化时炉墙温度场的变化规律.
Two aspects realizing the self-protect ability of a blast furnace cooling system with copper stave, adherent dross capability and adherent dross condition, were mainly discussed. Based on the copper stave in practice, a three-dimension heat transfer mathematical model of copper stave was established. Integration of the calculation with practice experience shows that the copper stave is more suitable for high loaded heat zone. The copper stave can provide with better adherent dross capability; but at the same time, only if having better adherent dross condition, the copper stave self-protect ability can be realized to get longevity and high productivity. The various elements of adherent dross condition were also analyzed.
