武汉科技大学本科毕业设计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I武汉科技大学本科毕业设计AbstractAccordingtotheexperienceofadvancedsteelenterpriseandtheknowledgethatwehavelearned,thetaskofourdesignistodesignanannualoutputof4.6milliontonsofsinterplantforWISCO.Thebasicityofthesintershouldbelimitedtotherangeof2.05to2.09,theironcontentofthesintershouldbelimitedtotherangeof56.2%to56.6%,andtheparticlesizeoftheproductionis50-5mm.Thesinteroreisoneoftheprimarymaterialforblastfurnaceironmaking,theproductivityandqualityofsinterorehavedirecteffectonblastfurnaceproduction.Soit’sveryimportanttodesignanfeasiblesinteringcraft.Designworkislaunchedfromfiveaspects:materialofironores,fluxes,fuel;size,workingrulesandproductionprogramofthesinterplant;equipmentsandbuildingofsinteringplantlayout;flowsheetofcraftsandmassbalancecalculation;environmentprotectionandcomprehensiveutilization.Thedesignhasreferredtotheexperiencesandtechnologyofdomesticplants,suchasMaGangSteelandWISCO,andintroducedsimplythecraftofthesintermachinethatwedesigned.Accordingtothedemandofthedesign,wecalculatedthemassbalanceandflowofcrafts,selectedthemainfacilitiesaftercalculation,andobtaintheconsumptionofironores,fluxes,fuelandsoon,andthenchosetheequipmentswhichwerematchedwithit.Inthedesign,lotsofadvancedcraftsandfacilitiesareapplied,someofthepreviouscraftsandfacilitieshavebeenimproved,andthetrendofthehighautomationandenvironmentprotectionisfullyconsidered.Theblueprintsofthedesignareaddedaccordingtothecalculation.II武汉科技大学本科毕业设计Keywords:Sintering;Flowofcrafts;Design;Automatedcontrol;Environmentalprotection目录前言...................................................................11绪论.................................................................21.1烧结机工艺设计的目的...............................................21.2烧结机工艺设计的依据及概况.........................................21.3烧结机工艺设计的要求...............................................31.4烧结厂厂区概况及厂址特点...........................................31.4.1厂区概况........................................................31.4.2厂址特点........................................................31.5烧结机工艺设计特点.................................................32原料、熔剂和燃料.......................................................52.1含铁原料...........................................................52.1.1含铁原料使用条件................................................52.2熔剂性质和入厂条件..........................................
