鞍山科技大学本科生毕业设计第页毕业设计年产120万吨冷轧带钢厂工艺设计摘要本设计是参考鞍山钢冷轧厂1780机组而进行的冷轧带钢工艺设计，典型产品为Q215，0.5×1000mm的冷轧带钢，本设计的目的是设计一个年产120万吨的冷轧带钢车间。主体设备有连续酸洗机组、五机架全连续冷轧机组、罩式退火炉、单机架四辊式平整机组、横切、纵切及重卷机组、连续热镀锌机组等。设计产品的品种主要有电工硅钢板、热镀锌板带等。产品具有使用规格范围宽、厚度精确、尺寸偏差小、表面光洁、板形好、性能稳定等特点。据此制定了轧制制度、并对轧辊强度进行了校核。另外，还校核了轧机年产量，计算了经济技术指标，并以连铸薄带夹杂物的品种与特性为专题进行了论述。【关健词】：冷轧带钢，轧制制度，全连续轧制，轧机，连铸薄带夹杂物Designofacoldstripplantwithannualcapacityof1.1millionstonsAbstractThedesignofacoldstripplanthasbeenintroducedandanalyzedinthispaper,accordingtoANSC′sColdstripplant2#line.ItstypicalproductisQ2151.8×1700mm.Itsmainequipmentsincludeshallow-tankpickingtrain,5-stand-fully-continuouscoldrollingtrain,hood-typeannealingfurnace,singlestand4-highskin-passtrain，6-zonepull-throughtypecontinuousannealingline，cross-cuttingandslittingtrainandcoilingtrain,ect.Theproductsmainlyincludecoldsheetandstrip,hot-dipgalvanizedsheetandstrip,hot-diptinnedsheetandstrip.Accordingtoit,weestablishedtherollingsystem,speedscheduleandcheckedtherollers’strength.Moreover,wecheckedtherollingmill’sproductivecapacity,cut-upunit’sproductivecapacityandcalculatedtheeconomicandtechnologyindex.Aspecialtopicaboutperformanceandproductivecharacteristicofautomobileleaf-springilluminateexistingstateofautomobileleaf-springandmomentumofdevelopmentofmanufacturingtechnique.Atlast,thisdesigncloseaplantplanmadewithAutoCADsoftware,aliteratureinEnglishandChineseaboutdynamicrecrystallizationunderwarmdeformationofa304typeausteniticstainlesssteel,programabouttherollingsystem,checkedtherollers’strengthandtherollingmill’sproductivecapacitywithMicrosoftVisualC++.【Keywords】sheetandstrip,rollingsystem,fully-continuouscoldrolling,rollingmillDesignofacoldstripplantwithannualcapacityof1.20millionstonsABSTRACTThedesignofacoldstripplanthasbeenintroducedandanalyzedinthispaper,accordingtoA.S.C′s1780mmColdStripMillPlant.ItstypicalproductisQ215，0.5×1000mm.Thepurposeistodesigna1.2millionColdStripMillPlant.Itsmainequipmentsincludecontinuouspickingtrain,5-sta
