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.
