武汉科技大学本科毕业设计 PAGE V 武汉科技大学本科毕业设计 PAGE 1 摘 要 本次设计任务是根据先进钢铁企业的生产经验和我们所学的知识，为武钢设计年产460万吨的烧结厂。要求碱度为2.07±0.02，全铁品位为(56.4±0.2)%，成品粒度为50-5mm。 烧结矿是高炉炼铁生产的主要原料之一，烧结矿的产量高低和质量好坏直接影响着高炉冶炼。因此，设计合理的烧结工艺是非常重要的。设计工作从五个方面开展：原料、熔剂和燃料；烧结厂生产规模，工作制度及产品方案；烧结厂设备配置及建筑物布置；工艺流程及物料平衡计算；环境保护及综合利用。 本设计参考了马钢，武钢及国内一些厂家的设计经验与技术,对所设计烧结厂的工艺方面进行了简要的介绍。根据设计的要求进行了物料平衡及工艺流程的计算，主要设备的选择计算，得出含铁原料、熔剂、燃料等的需要量，并选择与之相配套的设备。 在本设计中，采用了大量先进的工艺设备，同时对原有的一些工艺和设备进行了调整和更新，充分考虑了今后设备自动化及环境保护等方面的发展趋势要求。在计算的基础上还附加了图纸。 关键词： 烧结； 工艺流程； 设计； 自动化控制； 环境保护 Abstract According to the experience of advanced steel enterprise and the knowledge that we have learned ，the task of our design is to design an annual output of 4.6 million tons of sinter plant for WISCO.The basicity of the sinter should be limited to the range of 2.05 to 2.09, the iron content of the sinter should be limited to the range of 56.2% to56.6%, and the particle size of the production is 50-5mm. The sinter ore is one of the primary material for blast furnace ironmaking, the productivity and quality of sinter ore have direct effect on blast furnace production.So it’s very important to design an feasible sintering craft.Design work is launched from five aspects: material of iron ores,fluxes, fuel; size ,working rules and production program of the sinter plant;equipments and building of sintering plant layout; flowsheet of crafts and mass balance calculation; environment protection and comprehensive utilization. The design has referred to the experiences and technology of domestic plants, such as MaGang Steel and WISCO, and introduced simply the craft of the sinter machine that we designed. According to the demand of the design, we calculated the mass balance and flow of crafts, selected the main facilities after calculation, and obtain the consumption of iron ores, fluxes, fuel and so on, and then chose the equipments which were matched with it. In the design, lots of advanced crafts and facilities are applied, some of the previous crafts and facilities hav
