3500中厚轧机设计毕业设计论文

摘要I摘要现代板生产工艺在四辊可逆轧机中成为主要的机型，其工作原理是使工件通过2个相对旋转的轧辊产生加工压力，产生塑性变形。针对现有济钢和首钢3500中厚板轧机，通过辊系的微尺度等效杆系分析，消除普通四辊轧机暴露出的一些弊端，设计较高性能的四辊可逆式3500轧机；选择计算轧机的力能参数，设计轧机结构，计算主要结构参数。本次设计对四辊可逆轧机主传动系统进行设计分析，研究，计算，阐述了板轧机的历史发展以及国内外轧机的发展，确定坯料、轧制特点、主传动机构的组成、机架形式、轧制速度、轧辊的结构特点、轴承形式、润滑形式及经济性和环保性。首先对主传动系统力能参数进行了计算，包括轧制力、轧制力矩和主电机功率的计算及校核，其次是主要零件强度的计算，如轧辊、轴、轴承、机架。然后对系统的润滑进行分析和讨论并对本次设计中的经济性和环保性进行了详细的分析和论述。最后进行了数据的整合。关键词中厚板；闭式机架；轧辊；轧制力AbstractIIAbstractModernplateproductiontechnologyinfourrollerreversiblerollingmillbecomethemainmodels,theworkingprincipleistomaketheworkpiecethroughthe2relativerotationoftherollertoproduceprocessingpressure,produceplasticdeformation.InviewoftheexistingJinanIronandsteelandShougang3500platemill,throughandmicroscaleequivalentlinkageanalysis,eliminatethecommonfourrollersmillexposedsomedrawbacks,designhighperformanceoffourrollerreversibleof3500mill;selectionandcalculationofrollingforceandenergyparameters,designthestructureoftherollingmill,mainstructureparameters.Thedesignoffourhighreversiblerollingmillmaindrivesystemdesignandanalysis,study,calculation,expoundstheplatemillofhistoricaldevelopmentandrollingmillathomeandabroaddevelopment,determinethestructuralcharacteristicsofblank,rollingcharacteristics,themaintransmissionmechanismcomposition,mount,rollingspeed,roll,bearing,lubricationformandtheeconomyandenvironmentalprotection.First,themaindrivesystemparameterswerecalculated,includingrollingforce,rollingtorqueandthemainmotorpowercalculationandcheck,followedbythemainpartsofthecalculationofstrength,suchasroll,shaft,bearing,rack.Thenthelubricationofthesystemisanalyzedanddiscussed,andtheeconomicandenvironmentalprotectioninthisdesignareanalyzedanddiscussedindetail.Finally,theintegrationofthedataiscarriedout.Keywordsplate,rolling:rollingforce,:rollingmill目录III目录摘要............................................................................................................................IAbstract.......................................................................................................................II第1章绪论..................................................................................................................11.1中厚板轧机类型及发展.....................................................................................11.2国内外轧钢机械的发展状况.............................................................................2第2章轧机主传动方案及基本参数..........................................................................62.1轧机主传动方案设计.........................................................................................62.2基本参数.............................................................................................................82.2.2轧辊形状及尺寸的确定...............................................................................92.2.3轧辊传动端及轧辊速度的确定.................................................................10第3章轧制力能参数................................................................................................123.1轧制过程变形区及其参数...............................................................................123.2轧机的负荷图及电机功率...............................................................................17第4章轧辊校核........................................................................................................214.1强度校核...........................................................................................................214.2工作辊与支撑辊间的接触应力.......................................................................22第5章滑动轴承、机架校核....................................................................................255.1滑动轴承校核...................................................................................................255.2机架校核...........................................................................................................275.3机架应力及变形校核.......................................................................................33第6章可行性分析....................................................................................................366.1经济可行性分析...............................................................................................366.2环保性分析.......................................................................................................37结论..........................................................................................................................39参考文献......................................................................................................................40谢辞..........................................................................................................................411第1章绪论中厚板板轧机是用于轧钢设备的轧钢设备，在国民经济各部门都有广泛的用途。它主要用于制造运输工具（如汽车、拖拉机、船舶、铁道车辆、航空航天机械等）、钢铁机械部件，如各种储存容器、锅炉、桥梁等工业结构件、管道和一般机械产品。1.1中厚板轧机类型及发展生产中板的轧机型式很多。根据框架主体分类,可以分为两个滚筒,四辊、复合,几种通用类型。框架布局来分类,可分为单站、并列式和柱式、等的规格一般板轧机名义长度根据工作辊辊表面,如2300毫米,2300毫米和5500毫米。当前世界最大的一个是5500毫米轧机。像其他轧机,板轧机包括工作基础和传动装置,框架主要包括轧机机架、轧辊系统,平衡系统,压力装置,换辊装置。传动装置组成,大型电机和缓慢,由于汽车生产技术的发展在现代板轧机通常由电动机直接驱动。轧机的产生和发展经历了数百年,十九世纪中叶美国开始使用三辊劳特中板轧机,进入1950年代后,中国建立了20多套三辊劳特式轧机用于中板生产。从198
