辽宁科技大学本科生毕业设计第I页摘要热处理是机械工业的一项重要基础技术，通常像轴、轴承、齿轮、连杆等重要的机械零件和工模具都是要经过热处理的。热处理对于充分发挥金属材料的性能潜力，提高产品的内在质量，节约材料，减少能耗，延长产品的使用寿命，提高经济效益都具有十分重要的意义。正所谓“工欲善其事,必先利其器”，那么也就必须给热处理一个良好的环境及先进设备，总的来说就是一个设计得当的热处理车间。本设计的主要内容热处理的发展现状、方向和整个热处理车间的设计过程。从热处理车间的分类和特性、热处理车间生产任务、工作制度及年时基数、工艺设计、热处理设备的选择与计算、车间设备组织与布置、热处理车间建筑物与构筑物、车间动力和辅助材料消耗量计算、热处理的生产安全与环境保护、热处理车间劳动组织、人员配备和热处理车间技术经济指标等方面，对热处理车间进行设计。从热处理技术的现状和水平，掌握其发展趋势，大力发展先进的热处理新技术、新工艺、新材料、新设备，用高新技术改造传统的热处理技术，实现“优质、高效、节能、降耗、无污染、低成本、专业化生产”的方向上设计热处理车间。关键词：热处理;车间;热处理炉;弹簧;55SiMnVB辽宁科技大学本科生毕业设计第II页AbstractHeattreatmentisanimportantindustrialmachinerybasedtechnique,usuallylikeaxis,bearings,gears,connectingrod,andotherimportantmechanicalpartsandLabourmoldtakesaheattreatment.Heattreatmenttogivefullplaytotheperformanceofmetalmaterials,improvingtheproduct'spotentialinnerquality,savematerials,reducetheenergyconsumptionandprolongservicelifeoftheproduct,improveeconomicbenefithastheextremelyvitalsignificance.Istheso-calledsharptoolsmakewellitsthing,youwillhavetohavethedevice,itmustgiveheattreatmentagoodenvironmentandadvancedequipment,overallisadesignproperheattreatmentplant.Thedesignofthemaincontentheattreatmentdevelopmentpresentsituation,thedirectionandthewholethedesignprocessofheattreatmentplant.Fromtheheattreatmentplantclassificationandcharacteristics,heattreatmentplantproductiontasks,worksystemandtechnologydesign,inthebaseofheat-treatmentequipmentselectionandcalculation,workshopequipmentorganizationandarrangement,theheattreatmentplantbuildingsandstructures,workshoppowerandauxiliarymaterialsconsumptioncalculation,heattreatmentofproductionsafetyandenvironmentprotection,theheattreatmentplantlabororganization,personnelandtechnicalandeconomicindexesheattreatmentplantaspectsofdesign,heattreatmentplant.Fromthestatusandlevelofheattreatment,grasptheirdevelopmenttrend,anddevelopadvancedheattreatmentofnewtechnology,newtechnology,newmaterialandnewequipment,withhigh-techtransformingtraditionalheattreatmenttechnologytorealizehighquality,highefficiency,energysaving,consumptionreduction,nopollution,lowcost,specializedproductiondirectionsonthedesigntheheattreatmentplant.Keywords:Heattreatment;Workshop;Heattreatmentfurnace;spring;55SiMnVB辽宁科技大学本科生毕业设计第III页目录摘要.........................................................IAbstract......................................................II1综述........................................................11.1热处理工业的现状...............................................11.1.1我国热处理工业的现状........................................11.1.2其他国家热处理的现状........................................21.1.3我国和其他国家的差距........................................21.2我国热处理技术的发展战略.......................................31.3我国热处理产业的研究方向.......................................51.3.1多参数热处理................................................51.3.2复合热处理..................................................61.3.3采用新的淬火介质和改进淬火方法..............................61.4研制开发各种新型热处理设备.....................................71.5采用新的加热源和新的加热方式...................................81.6加强新材料与热处理工艺的紧密结合和相互促进.....................91.7重视热处理节能和环境保护......................................101.8小结..........................................................112车间产品方案的确定.........................................132.1产品方案列表..................................................132.2典型产品......................................................132.2.1弹簧的定义.................................................132.2.2弹簧的服役条件和失效形式...................................142.2.3弹簧的性能要求.............................................152.2.4弹簧的热处理特点...........................................153典型产品的热处理工艺.......................................163.1典型产品材料..................................................163.1.155SiMnVB钢的化学成分......................................16辽宁科技大学本科生毕业设计第IV页3.1.255Si2Mn钢中化学成分特点...................................163.1.355SiMnVB钢的力学性能及用途................................173.1.455SiMnVB热处理工艺的制定..................................173.1.5淬火工艺的制定.............................................183.1.6回火工艺的制定.............................................193.255SiMnVB热处理金相组织分析...................................203.2.1淬火处理后的组织...........................................203.2.2回火处理后的组织...........................................204热处理设备的选择...........................................224.1车间主要设备的选择............................................224.1.1选择设备应遵循的原则.......................................224.1.2加热设备...................................................224.1.3冷却设备...................................................234.2车间辅助设备的选择............................................244.3热处理设备明细表..............................................275热处理电阻炉的设计.........................................285.1炉型的选择....................................................285.2炉膛尺寸的确定................................................285.2.1炉底面积的确定.............................................285.2.2炉膛高度的确定.............................................295.2.3炉衬材料及厚度的确定.......................................305.3砌体平均表面积计算...............
