毕业设计(论文)-年产量155万吨冷轧带钢的车间设计

辽宁科技大学本科生毕业设计（论文）第I页资料年产量155万吨冷轧带钢的车间设计摘要本设计是参考鞍山钢铁公司1700mm冷轧车间设计的，年产量为155万吨，典型产品为Q215冷轧薄板带钢，产品规格0.61350mm。该车间设计主要包括：连续酸洗—冷轧联合机组、罩式退火机组、热镀锌机组、平整机组、剪切机组、重卷机组等。设计产品有冷轧带钢卷、冷轧板、热镀锌板、热镀锌钢卷、电工硅钢板。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。据此制定了典型产品金属平衡表和轧制规程，对轧机、电机能力进行了校核。计算了车间的各项经济技术指标，绘制了车间平面图，并以一种冷轧带钢吹吸式粉尘治理新技术为专题进行了综述。关键词：冷轧带钢；轧制工艺；酸洗—冷轧联合机组；轧制制度Designofacoldstripplantwithannualcapacityof1.55millionstons辽宁科技大学本科生毕业设计（论文）第II页ABSTRACTThisdesignreferstothe1700cold-rollingdepartmentofAnshanSteelCorporation,whoseannualoutputis1.55milliontons,andthetypicalproductistheQ2150.6×1350.Thisworkshopdesignmainlyincludes:Pickling-cold-rolledjointunit,cover-typeannealingfurnaceunit,entirecontinuousannealingunit,hotgalvanizesunit,electricalsteelannealedcoatingunit,singlestand4-highskin-passunit,crosscutandslittingshearingunit,recoilingunitandsoon.Thedesignedproducts,includingvolumesofcold-rolledstrip,cold-rolledplate,hotdipgalvanizedsheetandvolumes.Productswithdistinguishingfeaturessuchaswidesize,accuratethickness,smalldeviationindimension,smoothsurface,wellflateness,stableproperty,etc.Accordingtoit,Rollingschedulewasmadefortypicalproductandtheabilitytomillsandotherequipmentswerechecked.Andlayoutdrawingforthedesignplantwascompleted.AspecialsubjectaboutanewblowingandsuckingtechnologyofcollectingdustoncoldstripsurfaceKeywords:coldrolledstrip,rollingsystem,pickling–cold-rolledjointunit,rollingsystem.辽宁科技大学本科生毕业设计（论文）第I页目录1综述..........................................................................................................................11.1我国冷轧板带生产现状.................................................................................11.1.1冷轧设备的发展概况..........................................................................21.1.2冷轧生产技术的发展过程..................................................................21.1.2冷轧生产技术的发展..........................................................................31.1.3冷轧技术的发展..................................................................................41.1.4冷轧板带生产的新技术及发展趋势..................................................51.1.5结论......................................................................................................71.2板型控制的方法.............................................................................................71.3带钢产生厚度不均的原因和解决方法.........................................................91.4冷轧带钢表面质量自动检测系统的在线应用研究...................................131.4.1系统设计.............................................................................................131.4.2系统的功能模块和使用情况............................................................152产品方案和金属平衡.......................................................................................182.1产品方案的制定...........................................................................................182.1.1产品方案............................................................................................182.1.1生产方案............................................................................................182.2坯料的确定...................................................................................................192.2.1坯料的选择........................................................................................192.3金属平衡表的制定.......................................................................................202.3.1金属平衡............................................................................................203轧制工艺流程.....................................................................................................223.1冷轧板带钢生产的工艺流程.......................................................................223.2酸洗设备.......................................................................................................233.2.1酸洗设备原理....................................................................................233.2.2酸洗设备选择....................................................................................243.2.3酸洗设备参数....................................................................................25辽宁科技大学本科生毕业设计（论文）第II页4主要设备选择.....................................................................................................264.1设备组成.......................................................................................................264.2酸轧联合机组...............................................................................................264.3罩式退火机组...............................................................................................304.4平整机组.......................................................................................................314.5横剪机组.......................................................................................................324.6纵剪机组.......................................................................................................344.7重卷机组.......................................................................................................354.8热镀锌机组................................................................
