冷轧带钢车间毕业设计

辽宁科技大学本科生毕业设计1I年产量240万吨冷轧带钢车间设计摘要由于冷轧薄板具有很高的尺寸精度，表面质量和优良的综合性能，因此得到了越来越广泛的应用，成为国民经济中各生产建设领域所必须的材料，尤其是在家电板和汽车板的应用。本文结合鞍钢冷轧薄板厂的相关资料，同时参考了多家现代冷轧厂的资料，设计了年产240万吨1700冷轧车间。设计内容包括选择轧钢机形式、确定布置形式、根据典型品种（厚度为0.8mm）进行压下规程设计和有关计算（轧制力参数计算、轧辊强度校核和电机生产能力校核等）。主设备采用了酸轧联合机组，退火炉选择连续退火炉。本设计力图设计出能生产高档家电板和汽车板的冷轧薄板厂，所采用的设备都是经参考相关资料对比后选取的最佳设备，以保证产品的质量和生产的顺利进行，从而实现优质、高产、低消耗、环保的目标。关键词:冷轧薄板；酸轧联合机组；冷轧工艺与设备；压下规程辽宁科技大学本科生毕业设计IIIIAnnualproductionof2.4milliontonscold-rolledstripsteelplantdesignABSTRACTAsCold-rolledsheetwithhighdimensionalaccuracy,surfacequalityandexcellentoverallperformance,soithasbeenmorewidelyused,asthenationaleconomyoftheproductionfieldofconstructionmaterialsnecessary,especiallyinthehomeplateandcarplatesapplication.Inthispaper,AnshanIronandSteelColdRollingMilloftherelevantinformation,whilemakingreferencetoanumberofmoderncoldrollingmilldata,designedannualproductioncapacityof2.4milliontons1700coldrollingworkshop.Designelementsincludeselectmillforms,determinetheformlayout,accordingtothetypicalvarieties(thickness0.8mm)forrollingscheduledesignandrelatedcalculations(calculationofparametersoftherollingforce,rollstrengthcheckandmotorproductioncapacitycheck,etc.).Themasterdeviceusesarollingacidcombinedunit,selectacontinuousannealingfurnace.Thedesignseekstodesignaboardcapableofproducinghigh-endappliancesandcarplateCold-rolledsheetplant,equipmentusedwithreferencetorelevantinformationareselectedaftercomparingthebestequipmenttoensureproductqualityandsmoothproduction,inordertoachievehighquality,lowconsumption,environmentalprotectiongoals.Keywords:Cold-rolledsheet;Acidrolledjointunit;Coldrollingprocessandequipment；Rollingschedule辽宁科技大学本科生毕业设计IIIIII目录1综述........................................................................................................................11.1我国冷轧带钢生产特点及发展历史...................................................................11.1.1冷轧带钢的生产特点................................................................................11.1.2冷轧带钢的发展状况................................................................................21.1.3冷轧带钢生产中不断更新生产的技术.......................................................21.2冷轧的主要产品种类.........................................................................................31.2.1汽车板.....................................................................................................31.2.2电工硅钢板..............................................................................................31.2.3镀锡、镀锌板..........................................................................................41.2.4其它产品..................................................................................................51.3冷轧带钢的生产工艺现状..................................................................................51.3.1冷轧带钢的轧制工艺特点.........................................................................51.3.2冷轧带钢的生产工艺................................................................................61.4现代冷轧机的发展现状及趋势..........................................................................71.4.1现代冷轧机的类型特点............................................................................82产品方案的制定及金属平衡表..........................................................................92.1产品方案的制定................................................................................................92.2原料的选择.....................................................................................................102.2.1原料要求................................................................................................102.2.2热轧带钢卷的技术要求..........................................................................102.3金属平衡表的制定..........................................................................................112.3.1金属平衡................................................................................................112.3.2金属平衡表的制定.................................................................................113轧制工艺流程及轧制工艺制度........................................................................123.1规格................................................................................................................123.2冷轧薄板生产及工艺流程................................................................................123.3轧制规程制定.................................................................................................143.3.1压下规程的制定.....................................................................................143.3.2张力制度................................................................................................153.3.3轧辊转速的确定.....................................................................................153.4计算轧制力.....................................................................................................164生产设备的选择.................................................................................................224.1主要生产设备.................................................................................................224.1.1主轧机......................
