冷轧薄板车间设计VIP免费

摘要本设计说明书是参照鞍钢及宝钢冷轧薄板厂工艺流程，结合现代化生产实际要求设计了年产150万吨冷轧薄板钢厂的生产车间。典型产品为Q235B，20钢,08Al冷轧薄板带钢。该车间的主体设备包括：酸洗机组、五机架冷连轧机组、连续退火机组、单机架四辊式平整机组、横切、纵切及卷曲机组等。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。设计时以年产量为基础，结合各产品的市场前景合理地分配了各产品产量，制定了典型产品金属平衡表和轧制规程，并且优化了冷轧薄板的生产工艺，综合了各项技术经济指标，并绘制车间平面图。此外，本说明书还包括专题研究论文：Mg-4Zn-1.5RE合金轧制板材的再结晶组织观察与分析。关键词：冷轧薄板；热处理工艺；再结晶退火；车间设计ABSTRACTThisdesignmanualisasteelworkthatproducesandmanufactures1,500,000tonscoldrolllamellainoneyearcombiningmoderncapacityandphysicalrequirementstodesign,accordingtothecold-rolledsheetofAnshanIronandSteelandBaosteel.ThetypicalproductsareQ235B,20steeland08Alspecificationscold-rolledsheetsteel.Thisworkshopequipmentincludes:picklingline,thefivestandcoldrollingmill,continuousannealingunits,singleframefourrollerlevelingunit,crosscut,longitudinalcuttingandrewindingmachine,etc.Theproductcanbeusedinthecharacteristicsofthewidespecificationrange,precisethicknessandsmallsizedeviation,smoothsurface,goodboardshape,thestableperformanceandsoon.Peoplehaveassignedeachproductoutputreasonablyanddrewupthemetalbalancedofthetypicalmodelproductandstrandingsystemregulationscombiningeachproduct'smarketprospect,basedonannualoutputwhendesigning.Notonlythose,butalsopeoplehaveoptimizedproductionprocessofthecold-rolledsheet,synthesizedvarioustechnicalandeconomicindicators,anddrewtheworkshopplan.Inaddition,themanualalsoincludedaspecialsubjectsearchthesis:observationandanalysisoftherecrystallizationoftheMg-4Zn-1.5REalloystrandingsystemboardmaterialorganizes.Keyword：Coldrolledsheet;Heattreatmentprocess;Recrystallizationannealing;Workshopdesign目录摘要................................................................................................................IABSTRACT.........................................................................................................II目录.................................................................................................................III1综述................................................................................................................11.1冷轧薄板简介...................................................................................................................11.2冷轧薄钢板生产工艺特点...............................................................................................21.3冷轧钢板的分类...............................................................................................................31.4冷轧薄板的质量控制.......................................................................................................31.4.1钢的化学成分对成品性能的影响.............................................................................31.4.2热轧带钢对冷轧钢板性能和组织的影响.................................................................51.4.3原料的几何尺寸对冷轧成品尺寸的影响.................................................................61.4.4坯料常见缺陷以及对冷轧生产的影响.....................................................................71.4.5退火工序中存在的缺陷.................
