带钢车间工艺

安徽工业大学毕业设计（论文）报告纸第1页共2页年产206万吨短流程带钢车间工艺设计摘要薄板坯连铸连轧是20世纪80年代末、90年代初开发成功的生产热轧板卷的一项短流程工艺，是继氧气转炉炼钢、连续铸钢之后钢铁工业最重要的革命性技术之一。薄板坯连铸连轧集科学、技术和工程于一体，将热轧板卷的生产在一条短流程的生产线上完成，充分显示出其先进性和科学性。世界各国都对此给予了极大关注，使得薄板坯连铸连轧技术近年来又有了突飞猛进的进展。与传统生产工艺流程相比，短流程可节约投资、提高成材率、降低生产成本、大幅度缩减生产周期等。本设计为年产206万吨薄板坯连铸连轧热轧带钢生产车间设计，论文叙述了薄板坯连铸连轧技术的类型、市场分析及工艺技术特点，并把各种典型工艺进行了比较。参照国内外企业的技术特点和生产实践，提出了本车间的总体配置方案，设计了主辅设备及其生产能力计算、车间平面布置和起重运输、主要经济技术指标、环境保护以及使用AutoCAD绘制车间平面布置图。并运用VB程序进行了压下规程程序设计和相应的校核等。本设计选用的是CSP工艺，车间主要布置为：2流50/70CSP连铸→辊底式均热炉→高压水除鳞→7架CVCplus连轧机→层流冷却→卷取。采用了铁素体轧制技术、半无头轧制技术等新技术。关键字:薄板坯连铸连轧；CSP；热轧带钢车间设计;七机架精轧机组；压下规程程序设计安徽工业大学毕业设计（论文）报告纸第2页共2页TheDesignofaShortStripProcessPlantwithanAnnualOutputof2.06MilliontonsAbstractCSPisthesuccessfuldevelopmentoftheproductionofhotrolledcoilinashortenedprocess,theoxygenconvertersteelmaking,continuouscastingsteelindustryafterthemostimportantrevolutionarytechnologyinthelate1980sandearly1990s.Oneoftheforeignsteelmajorpowershaveinvestedagreatdealofmanpowerandresourcestothespecialstudy.CSP--science,technologyandengineeringinone,hotrolledcoilproductioninashortlinetocompletetheprocess,fullydemonstrateditsadvancedscientific.Allcountriesintheworldhavegivenagreatdealofconcern,makingCSPtechnologyarapidprogressinrecentyears.Comparedwiththetraditionalproductionprocess,theCSPprocesscanbeshort-savinginvestment,tobecomeusefulraiseratesandreduceproductioncostsandsignificantlyreducetheproductioncycle,andsoon.Thedesignforanannualoutputof2.06milliontonsofCSPhot-rolledstripsteelproductionworkshopdesignedpaperdescribestheCSPinthetypeoftechnology,marketanalysisandtechnologyfeatures,andtypicalofavarietyofmusiccomparison.ReferencetoMagangCSP,thetechnicalcharacteristicsandproductionpractice,raisedtheoverallconfigurationoftheworkshopprograme,themaindesignofauxiliaryequipmentanditsproductioncapacity,theplantlayoutandliftingthetransport,mainlyeconomicandtechnicalindicators,environmentalprotectionandtheuseofAutoCADDrawingWorkshopLayoutplans.VBproceduresandtheuseoftheorderreductionprogramdesignandthecorrespondingcheck,andsoon.TheCSPisthechoiceofdesignprocess,layoutforthemainworkshop:2-50/70CSPCasting→Roller-bothhigh-pressurehotwaterheaters→Descaling→7-CVCplusrollingmill→laminarcooling→coiling.Useferriterollingtechnology,semi-rollingtechnology,andothernewtechnologies.Keywords:thinslabcontinuouscastingandcontinuousrolling；CSP;hotstripplantdesign;sevenframeworkfinishingmillgroup;depressdetectiverulesprogramdesigning安徽工业大学毕业设计（论文）报告纸第1页共7页目录摘要................................................................................................................................11概述..............................................................................................................................11.1热轧板带轧制生产的现状..............................................................................11.2国内外薄板坯连铸连轧技术..........................................................................21.3国内外薄板坯连铸连轧产品市场分析.........................................................21.4本设计采用的新技术......................................................................................32产品大纲和金属平衡图.............................................................................................42.1产品方案...........................................................................................................42.1.1产品规格................................................................................................42.1.2产品按厚度的分配表...........................................................................42.2生产钢种...........................................................................................................42.2.1产品执行标准.........................................................................................52.2.2金属平衡表............................................................................................53设计方案......................................................................................................................63.1工艺方案的选择与确定..................................................................................63.1.1常规热连轧与薄板坯连铸连轧的比较选择......................................63.1.2几种典型的薄板坯连铸连轧工艺比较选择.......................................73.1.2.1各工艺的布置及特点.................................................................73.1.2.2工艺对比分析..............................................................................93.1.2.3应用选型......................................................................................93.1.3薄板坯连铸连轧存在的不足................................................................93.2轧机机型的选择.............................................................................................103.2.1PC轧机.................................................................................................113.2.2CVC轧机..............................................................................................113.2.3CVC轧机与PC轧机的比较..............................................................113.3加热炉选型................................................................................................
