Combined with investigation results of the furnace body erosion before relining, this paper analyzes the cause of production problems appeared in the first campaign life of the blast furnaces. Because of the existence of design shortcomings in large cooling block and bosh cooling stave, it resulted in poor furnace performance, such as stronger peripheral gas flow and irregular profile. The quick rise of bottom temperature of No.7 BF was caused by the penetration of molten iron into the joint of bottom carbon block, wheresas the quick rise of bottom temperature of No.6 BF was due to gas fleeing through the furnace bottom.

结合大修前炉体破损情况，对这两座高炉第一代炉役生产中出现的问题进行了调查研究。7号高炉大型模块和炉腰冷却壁设计上存在不足，引起高炉边缘气流发展，操作炉型不合理，炉况不顺；7号高炉炉底温度偏高是炉底炭砖渗铁造成的，6号高炉炉底温度偏高是炉底串煤气所致；7号高炉铁口失常的主要原因是铁口组合砖损坏严重和该部位炉壳开裂。
