安徽工业大学工商学院毕业设计（论文）说明书年产63万吨热轧线材车间设计摘要根据毕业设计的要求，设计年产63万吨的热轧高速线材生产车间，采用单线轧制方式。产品规格为Φ5.5~16mm，单卷盘重约2吨。本设计产品包括碳素结构钢和优质碳素钢。本车间设计的内容主要有：产品大纲和金属平衡表的制定；设计工艺方案和工艺流程；工作制度的确定及轧机生产能力分析；主要设备的选择；辅助设备的选择及计算；车间平面布置及起重运输；车间技术经济指标；环境保护；孔型设计；轧机力能参数计算及电机设备校核等。本设计原料采用连铸坯，以减少金属的损失，而且连铸坯的组织结构较好，这也提高了产品的质量；还可以减少轧制间隙时间，提高生产率。加热炉为步进梁式加热炉，进出料方式采用侧进侧出，以保证炉子的严密性，加热能力为120t/h。加热炉由微机控制，出炉温度为1050~1250°C。轧机采用高速线材轧机，全线均为无扭轧制，终轧保证速度为100m/s，最高轧制速度为120m/s。为改善产品微观组织，轧后采用控制冷却技术，轧后冷却通过水冷箱和一套斯太尔摩冷却运输系统来完成。斯太尔摩冷却运输系统采用延迟型冷却运输装置，它适用于冷却各类碳钢，具有较好的冷却效果。总之，上述先进工艺技术和设备是本设计的产品高质量的重要保证；同时也为高线生产车间设计提供了一个很好的样板。共2页第1页关键词：车间设计高速线材线材轧机控制轧制┊┊┊┊┊┊┊┊┊┊┊┊┊装┊┊┊┊┊订┊┊┊┊┊线┊┊┊┊┊┊┊┊┊┊┊┊┊安徽工业大学工商学院毕业设计（论文）说明书Aworkshopofnewhotrolledhigh-speedwirewiththeoutputof630,000t/aAbstractAccordingtotherequirementsofgraduationdesign,anewsinglelineofhigh-speedwirerodworkshopwiththeoutputof630,000t/awillbebuilt.Productspecificationsarefor5.5~16mmdiameter,eachcoilweighsabout2tons.Theproductsinthisdesignincludethecarbonstructuralsteelandhigh-qualitycarbonsteel.Themaincontentsofthedesignaremainlyasfollows,formulationofproductsschemeandmetalbalance,designoftechnologicalplanandprocess,thedeterminationofworkroutineandproductioncapacityanalysisofrollingmill,choiceofthemainequipment,choiceandcalculationoftheauxiliaryequipment,thegroovesdesign,thelayoutofworkshopandhoistingandconveyingequipment,checkofrollstrengthandmotorpower,technicalandeconomicindicatorsoftheworkshopandenvironmentalprotectionetc.Thecontinuouscastingbilletisusedasrawmaterialsinthisdesigntoreducethemetalloss.Thebettermicrostructureofthebilletscanalsoimprovethequalityoftheproductandreducetherollinggaptimetoincreaseproductivity.Thereheatingfurnaceisawalkingbeamtypefurnacewhichissideentryandsideexittoensurethetightnessofthefurnace.Theheatingcapacityis120t/h.Thefurnaceiscontrolledbythecomputer.Theexittemperatureis1050~1250°C.Thehigh-speedwirerodmillisusedinthisworkshop.Notwistrollingisrealizedacrosstherollingline.Thefinishingensurespeedis100m/s,maximumrollingspeedof120m/s.ThecontrolledcoolingtechnologyisusedafterrollingthroughthecoolingwaterboxandaStelmorcoolingconveyorsystemtoimproveproductmicrostructure.Stelmortransportationsystembythedelayedcoolingtypecoolingtransportdevices,whichappliestovariouscarbonsteelsandhasbettercoolingeffect.Inshort,theadvancedtechnologyandequipment,thedesignoftheproductisanimportantguaranteeofhighqualityandprovidingagoodmodelforthehighspeedwireproductionworkshopdesigning.共2页第2页KeyWords:workshopdesignhigh-speedwirerodandwiremillcontrolledrolling┊┊┊┊┊┊┊┊┊┊┊┊┊装┊┊┊┊┊订┊┊┊┊┊线┊┊┊┊┊┊┊┊┊┊┊┊┊安徽工业大学工商学院毕业设计（论文）说明书目录引言....................................................................................................
