毕业设计高炉本体设计

内蒙古科技大学毕业设计说明书.内蒙古科技大学本科生毕业设计说明书题目：包头地区原料条件下1500m3高炉本体设计学生姓名：学号：专业：冶金工程班级：冶金09-1指导教师：内蒙古科技大学毕业设计说明书I摘要高炉炼铁是获得生铁的主要手段，高炉是炼铁的主要设备，高炉本体设计是炼铁厂设计的基础。本着优质、高产、低耗和对环境污染小的方针，长寿与高效是高炉设计与生产所追求的目标。本设计说明书进行的详细的设计及计算，同时结合国内外一些大型高炉的先进生产操作经验及相关的数据。力求设计的高炉做到高度机械化、自动化和大型化。以期达到最佳的生产效益。本设计为1500m3高炉本体设计，所设计的炼铁高炉采用的高径比为2.78，高炉的有效利用系数为2.3t/(m3٠d)。车间采用岛式布置，出铁场采用圆形出铁场。其炉底和炉缸采用的先进的“陶瓷杯”技术来砌筑，从而达到了隔热保温、减少热损、保护炭砖的目的。炉腹部位用耐火度较高的铝碳转，炉腰和炉身下部用抗渣和防震较好的碳化硅砖，而炉身上部和炉喉用抗刷和抗侵蚀较好的高铝砖。高炉冷却方法采用了炉壳喷水冷却，和板壁结合的方式达到冷却效果，其中板壁结合中用到的冷却壁有光面冷却壁、第三代和第四代冷却壁。合适的钢结构和高炉基础设计保证了高炉的正常冶炼。关键词高炉；炉衬；冷却系统；钢结构内蒙古科技大学毕业设计说明书IIAbstractBlastfurnaceironmakingisthemainmeansforpigiron,themainequipmentofironmakingisblastfurnace,blastfurnacedesignofontologyisthefoundationoftheironmilldesign.Inlinewithhighquality,highyield,lowconsumptionandpollutiontotheenvironmentpolicyofsmall,longlifeandhighefficiencyisthegoalofthedesignandproductionoftheblastfurnace.Thisdesignmanualfordetaileddesignandcalculation,atthesametime,combinedwithsomelargeblastfurnaceathomeandabroadadvancedproductionoperationexperienceandrelateddata.Strivetodesignblastfurnaceofhighmechanization,automationandlarge.Inordertoachievethebestproductionefficiency.Thisdesignfor1500m3blastfurnacebodydesign,Thedesignoftheblastfurnacehighaspectratioof2.78,theeffectiveutilizationofblastfurnacecoefficientof2.3t/(m3٠d).WorkshopusestheislandtypelayoutcasthouseusingcircularcasthouseBlastfurnacebottomandhearthusesadvancedtechnologytobuildingceramiccup,soastoachievetheheatinsulationheatpreservation,reduceheatlossandprotectthecarbonbrick.Furnacebellywithhighrefractorinessofaluminumcarbon,boshandfurnacebodywithgoodslagresistanceandshock-proofcarborundumbrick,Thefurnacebodyandbrushwithresistanceanderosionresistancefurnacethroatgoodhighaluminabrick.BlastfurnacecoolingmethodUSESafurnaceshellwaterspraycooling,coolingeffectandpartitionway,combinedwiththewoodenpartitionusedincoolingstavecoolingwallhassmoothsurface,thethirdandfourthgenerationofcoolingstave.Appropriatesteelstructureandfoundationdesignguaranteesthenormaloftheblastfurnacesmeltingblastfurnace.Keyword:blastfurnacebody;thelining;ofblastfurnacecoolingsystem;steelstructure内蒙古科技大学毕业设计说明书III目录摘要............................................................................................................................................IAbstract....................................................................................................................................II目录.......................................................................................................................................III第一章文献综述.....................................................................................................................11.1高炉炉型概述.................................................................................................................11.1.1高炉炉型的发展......................................................................................................11.1.2高炉炉龄及其影响因素..........................................................................................21.2高炉炉衬的发展.............................................................................................................21.2.1高炉各部分耐火材料的选择..................................................................................21.2.2我国最新对耐火材料的选择..................................................................................41.3高炉的冷却设备.............................................................................................................41.3.1高炉冷却的必要性..................................................................................................41.3.2高炉冷却的目的......................................................................................................51.3.3高炉冷却的方式......................................................................................................51.3.4高炉各个冷却方式的发展以及优缺点..................................................................61.4高炉钢结构以及高炉基础的概述...............................................................................101.4.1高炉的钢结构以及影响因素................................................................................101.4.2我国高炉钢结构设计的基本现状........................................................................111.4.3我国在高炉钢结构设计上的差距........................................................................121.4.4高炉基础的概述....................................................................................................131.5高炉设计方案...............................................................................................................15第二章炼铁工艺计算...........................................................................................................172.1原料成分及参数选择...................................................................................................172.1.1原料成分................................................................................................................172.1.2参数选择.......................................................................................................
