河北联合大学轻工学院COLLEGEOFLIGHTINDUSTRY,HEBEIUNITEDUNIVERSITY毕业设计说明书设计(论文)题目:设计年产250万吨的1700热轧薄板车间学生姓名:学号:专业班级:学部:材料化工部指导教师:2012年5月21日摘要I摘要热轧薄板在板材中是最重要的钢材品种,广泛的应用于集装箱、汽车、铁路机车、车厢、管道、钢瓶等工业制作行业,也是冷轧板及其深加工产品的基材。世界各国近年来都在注重研制和使用连铸连轧等新技术和新设备来生产板带钢。本设计为年产250万吨的1700热轧薄板生产车间设计,论文主要内容包括:原料的选择、生产工艺的制定、典型产品工艺计算、主要设备和辅助设备的选择,并且对主要设备(轧辊和电机)的能力进行了校核,生产车间布置和环境保护,进行了设计和规划。本着多品种,多规格的原则制定了产品大纲,产品规格为:5mm。所用钢种为:普碳钢、合金结构钢、不锈钢(约含25%)。其中包括汽车大梁钢、船板钢、管线钢等等,并以其为出发点,尽量从工艺上使产品作到高质量、高附加值。首先根据总延伸,确定了轧制道次,并以6+6的形式分配粗精轧的道次,即粗轧6个道次、精轧6个道次。其中粗轧采用双机架连轧,同时可逆轧制,这样既可以缩短轧制间隙时间,又可以减少车间距离,从而减少投资。接下来就是设备选型问题,根据产品规格和设计要求,确定轧机各主要部件的尺寸以及一些必要的工艺参数。本设计经过仔细比较,并结合现场使用情况,选用了4架CVC轧机放在精轧机组的前段,这对产品的板形控制起到了关键作用,再加上工作辊弯辊,产品的板形控制能力应该可以得到提高。关键词:热轧;薄板;工艺计算;典型产品;设备ABSTRACTIIABSTRACTHot-rolledsteelplateinplankisthemostimportantsteelvarieties,widelyusedincontainer,automobile,locomotives,carriage,piping,cylinderandotherindustrialproductionindustry,isalsothebasematerialofcoldanddeepprocessingproducts.suchascontinuouscasting-rolling,aredevelopedtoproducethesmallsizeincross-sectionalloysteelshapeinthevariouscountries.Thedesignisamanufacturingworkshopofhotrollingplatewithaoutputof250thousandtons.Thepapermainlyincludestheselectionofrawmaterialandsubsidiaryfacilitiesandmainfacilities,formulationofproducetechnology,technologycalculationofthetypicalproduction,proofreadingthecapacityofmainfatuities(includingrollersandtheelectricalmachinery).Settingabouttheproductsdesignitplansexactlyitsarrangement,environmentprotectionandsoon.Totheprincipleofmorevarietiesandmorespecifications.Itsproductspecificationsrangefrom5mm,usedsteelsofcarbonsteel、alloyedsteel、stainlesssteel(25%).wedevelopaproductprogramincludingautomobilebigjoiststeel,shipplatesteel,pipelinesteelandsoonandtakingitasthestartingpointmaketheproductshighgradeandthehighattachmentvalueasfaraspossibl.Firstofall,accordingtothetotalextension,wedeterminethepassofrollingandallocatetotheroughrollingsixpassesaswellasfinishrolling.Roughrollingusesthedouble-standmillforcontinuedandreversiblerollingsothatwecanreducerollinggaptime,thedistancesoftheworkshopandinvestment.Nextistheissueofequipmentselection.Accordingtoproductspecificationsanddesignrequirementsweidentifythemajorcomponentsofthemillsizeandthenecessaryparameters.Aftercarefulcomparison,combiningwiththefieldusesituationweselectfourmillsonthefirstpartofthefinishrolling,whichplayakeyroleintheplateshapecontroloftheproduct.Workingtogetherwithworkrollbending,plateshapecontrolwillnotbeaproblem.【Keyword】hotrolling,plate,technologycalculate,typicalproduct,facility目录III目录摘要.........................................................................................................................IABSTRACT..................................................................................................................II第1章绪论..............................................................................................................11.1建厂的依据及车间的概述..................................................................................11.1.1建厂的依据...................................................................................................11.1.2地理优势.......................................................................................................21.2热轧薄板生产状况..........................................................................................31.2.1热轧宽薄板生产状况..................................................................................41.2.2热轧窄薄板生产状况..................................................................................61.3热轧薄板市场前景和需求概况.........................................................................61.3.1热轧宽薄板市场前景..................................................................................61.3.2热轧窄薄板市场需求..................................................................................71.4今后热轧薄板的发展趋势.................................................................................71.4.1热轧薄板发展方向..........................................................................................71.4.2热轧窄薄板发展方向..................................................................................71.5本设计的目的和意义.........................................................................................8第2章生产方案及产品大纲的制定.......................................................................102.1产品方案的编制...............................................................................................102.1.1产品方案....................................................................................................102.1.2编制产品方案的原则及方法....................................................................102.1.3选择计算产品............................................................................................102.1.4产品规格....................................................................................................112.1.5确定产品大纲............................................................................................122.2生产方案...........................................................................................
