180t氧气炼钢转炉的设计.docVIP

摘 要 自1952年第一座氧气顶吹转炉投产以来，氧气顶吹转炉的实践表现出很多的优点，使氧气顶吹转炉炼钢法逐渐的成了世界炼钢的主要方法。随着社会的发展，对钢材的求也越来越。SM400ZL。最后对所设计转炉炉体的高径比进行校核，高径比满足条件，可认为所设计的炉体尺寸是合适的，能够保证转炉的正常冶炼进行。 关键词 转炉炉体，炉型，炉衬，炉壳 ABSTRACT Since 1952 first BOF put into operation, the BOF practice showed a lot of advantages, the top-blown oxygen converter steelmaking method gradually became the worlds steelmaking method. With the development of society, all steel demand is also increasing. In order to meet all sectors of society to face the demand for steel, improved steelmaking production processes and equipment is essential. As one of the main equipment，the BOF converter furnace design is directly related to the production of steel-making, quality, furnace, cost and safety. Design 180t oxygen top-blown converter furnace as the goal, that can ensure safety production facility was reasonable designed out. The design of the converter furnace includes the furnace profile design, lining design and the furnace shell, the convergence of the other subsidiary parts of the furnace, make the appropriate design of the converter trunnion ring and trunnion. The design of furnace includes the choice of furnace profile, determine the furnace volume ratio and furnace size. Lining design is aimed to choose the lining material and determine the lining thickness, in order to improve the quality of molten steel, increase the lining life and reduce the lining cost, the new magnesium calcium carbon brick was chosen as a lining material. For the design of the furnace shell, in order to increase the safety factor of production and furnace life, a new furnace shell material SM400ZL with better comprehensive performance was used. Last check the height to diameter ratio of designed converter furnace. The height to diameter ratio could meet the conditions, it could be concluded that the design of the furnace size is appropriate to ensure the normal smelting converter.
