摘　　要：介绍新钢7号高炉炉缸结构及被侵蚀状况,认为炉缸冷却水水量过大,碱金属、锌富集及铅害破坏炉衬,炉型设计和冷却方式的选择不匹配,是影响高炉长寿的主要问题。通过前期建立高炉长寿管理制度、加强冷却系统的日常监控、科学判断炉缸侵蚀变化趋势,后期采取经济冶强、钒钛矿护炉、适当堵风口等措施,较好地控制了冷却壁的热流强度,实现了高炉长寿生产的目的。This paper introduces No. 7 blast furnace hearth structure and the status of the erosionstatus. Hearth cooling water volume is too large,enrichment of alkali metal,zinc and lead pollution damage furnace lining,furnace design and the choice of the ways of cooling type don＇ t match,is the major problems affecting BF longevity. To build bf longevity by early management system,strengthen the cooling system of daily monitoring,scientific judgment hearth erosion change trend,take economy strong,the vanadium and titanium ore smelting furnace protection and appropriate plugging tuyere in the late stage,better control the cooling wall heat flux intensity,the purpose of longevity and blast furnace production is realized.
