It is being used more and more abroad. The long campaign technologies of blast furnace is one of the most important measures which reduce the iron making production cost and improve the economic profits of Iron and Steel Company. In the design of large BF, the technologies like optimized BF profile, reasonable hearth lining, copper stave, soft water closed circulating cooling system and thin-walled lining etc. were applied to prolong BF campaign life. The basic concept of designing long campaign blast furnace was put forward. In order to adapt to the trend, during designing long campaign blast furnace, the rational; furnace profile, rational furnace lining structure and selection of different refractories for various areas, cooling method and system (including cooler structure and material, cooling water and so on) and concerned aspects must be comprehensively considered.In the design of hearth bottom adopts high quality carbon brick masonry; Bosh adopts high refractoriness, high volume density roughly the density of aluminum carbon brick masonry; Furnace waist, bosh has good wear resistance, thermal impact of SiC brick masonry; Shaft adopts the abrasion resistance, impact resistance, resistance to alkali erosion of high alumina brick masonry.
