四辊可逆冷轧机传动电控系统设计-毕业(设计)论文.doc

重庆科技学院本科生毕业设计中文摘要PAGEII摘要轧制是各种变形手段中效率高、产量大、成本低、成型精确的加工方式。而轧机是实现金属轧制过程的设备，泛指完成轧材生产全过程的装备，包括有主要设备﹑辅助设备﹑起重运输设备和附属设备等。从炼钢厂出来的钢坯还仅仅是半成品，必须到轧钢厂去进行热轧与冷轧后，才能成为合格的产品。论文通过吸收和借鉴校内实训中心的四辊可逆冷轧机的先进设计理念，提出了四辊可逆冷轧机的电控系统设计方案，并总结出了电气调试方案。完成了整个轧机电控系统的硬件方案设计以及相关器件的选型工作。在硬件设计中，提出了PLC+变频器+电机等的闭环控制系统，从而达到变频器控制电机转速的目的。关键词：轧机电控系统四辊闭环重庆科技学院本科生毕业设计英文摘要ABSTRACTMeansallkindsofdeformationinrolling,highefficiency,largeoutput,lowcost,precisionmoldingprocessingmethods.Themillistheequipmentofmetalrollingprocess,rolledthewholeproductionprocessreferstothecompletionofequipment,includingmajorEquipment,AuxiliaryEquipment,liftingandothertransportequipmentandancillaryequipment.Outfromthesteelmillisjustthesemi-finishedbilletstobetogoforhotandcoldrollingmills,theproductscanbecomequalified.Articlesbyabsorbandlearnthefour-campustrainingcenterrollercoldrollingmilloftheadvanceddesignconcept,putforwardafour-highreversingcoldrollingmillelectricalcontrolsystemdesign.Completionoftheentirerollingmillelectricalcontrolsystemhardwaredesignandselectionofwork-relateddevices.InthehardwaredesignisproposedsuchasPLC+inverter+motorclosed-loopcontrolsystem,soastoachievethepurposeinvertercontrolmotorspeed.Keywords:Rollingmill；ElectronicControlSystem；Fourroller；Closedloop重庆科技学院本科生毕业设计目录目录中文摘要……………………………………………………………………………Ⅰ英文摘要……………………………………………………………………………ⅡTOC\o"1-2"\h\z\uHYPERLINK\l"_Toc263755394"1绪论PAGEREF_Toc263755394\h1HYPERLINK\l"_Toc263755395"1.1轧制过程自动化PAGEREF_Toc263755395\h1HYPERLINK\l"_Toc263755396"1.2轧机的分类PAGEREF_Toc263755396\h2HYPERLINK\l"_Toc263755397"1.3四辊可逆冷轧机传动系统的电气要求PAGEREF_Toc263755397\h5HYPERLINK\l"_Toc263755398"1.4本设计的意义及工作PAGEREF_Toc263755398\h6HYPERLINK\l"_Toc263755399"2四辊可逆冷轧机的结构及工艺流程分析PAGEREF_Toc263755399\h8HYPERLINK\l"_Toc263755400"2.1四辊可逆冷轧机的发展和技术特点分析8HYPERLINK\l"_Toc263755401"2.2四辊可逆冷轧机的结构PAGEREF_Toc263755401\h11HYPERLINK\l"_Toc263755402"2.3冷轧工艺流程PAGEREF_Toc263755402\h14HYPERLINK\l"_Toc263755403"3四辊可逆冷轧机的控制单元PAGEREF_Toc263755403\h17HYPERL
