新型铝型材挤压模具快速加热装置简介NewStyleRapidAluminumProfileDieHeatingOven铝型材挤压模具是铝型材加工生产重要的组成部分，模具炉是配合挤压机使用的设备，将模具加热至铝棒相近的温度，有利于挤压成型。在行业中，一般使用的模具加热通常是电阻加热炉，电阻发热体发热后，除向通孔内胆传热外，还用热风循环风机，把发热体产生的热量通过空气传递进内胆，使模具加热。Extrusiondieofaluminiumprofileisanimportantpartofprocessingandproducingaluminiumprofile.Workingwithextrudingmachine,thedieheaterheatsupdietothetemperatureclosetoaluminiumbar'sinfavorofultimateshaping.Normally,electricresistaceheatingovenisusedfordieheatingintheindustry,whichfirstheatsupresistanceheatingelement,andthentransfersitsproducedheattolinerwithaccessibleholesandotherlinersthroughairusinghotwindcyclingmachinetowarmupthedie.电阻炉加热的方式长时间来存在着以下的缺陷：OldElectricresistaceheatingovenmethod'sdefects:1、用电功率较大，耗电量很大，使用成本髙。Largeelectricpowerconsumption,largeelectricityconsumption,highusingcost;2、加温时间长，一般常温加热至500℃时间需要2-3小时。（200mm模）Longheatingtime:2-3hoursareneededtoheatfromnormaltemperatureto500℃(200mmdie);3、对电阻发热管的均匀度要求很高，否则会造成局部温度过高现象Highdemandforuniformityoftheelectricresistanceheatingtube,otherwiseoverheatingphenomenoninpartswilloccur;4、电阻丝的电阻随温度变化而变化。加热箱环境温度高Electricresistanceofresistingwirevarieswiththevariationoftemperature,whiletheenvironmentaltemperatureofheatingovenisveryhigh;5、设备笨重占地多，取模不便，而且发热管寿命短，对维护及生产安全带来隐患。Equipmentislargeandheavy,occupyingalargearea;difficulttotakeoutdies;shortservicelifeofheatingtubes;hiddentroublesformaintenanceandproductionsafety.更重要的是使用传统的加热炉对模具存在着致命的损害，严重缩短了模具的使用寿命和影响产品质量。模具温度对于获得高的产量起着重要的作用，一般不得低于430℃；另方面，也不得过高于500℃，否则，不但硬度可能下降，同时模具工作面会产生氧化；模具在长时间高温下加热（特别在超过金属居里点）模具金属易疲劳易开裂，影响产品质量。（特别是用油、煤加热对模具产生氧化、模具回炉退火率、模具易开裂的影响）Moreimportantly,traditionalheatingovenwilldeadlydamagethedie,largelyshortenitsservicelifeanddecreaseitsquality.Thetemperatureofthedieplaysasignificantroleforyield,whichnormallymustbe≥430℃and≤500℃,orthedie'shardnessmightfallanditsworkingsurfacemayoxidize.Heatedinhightemperatureforalongtime(especiallyoverthemetalcuriepoint),thediemetalisliabletowearyandcrack,especiallywhenusingoil,coaltoheat,it'seasytomakedieoxidizeandcrackaswellasinfluenceitsreheatingandannealingratio.本公司最新推出的ANSA-JRA高效挤压模具加热设备，迎合现阶段铝业市场的发展需要，对型材加工企业很好的一种提高生产效率的节能降耗设备。温度控制精准，模具加热到设定温度后，可自动退出加热控制系统，耗电极小。采用先进的隔离磁能感应加热，使得生产过程中安全系数大大提高。设备使用寿命更长。由于模具加热可自动操作，加热时间短，可做到快速换模，减少作业时间，提高生产效率。改善了模具分类加热的协同操作，达到更换挤压模具的快速性和准确性。OurcompanynowputsforwardANSA-JRAfastheatingdeviceforextrusiondie,astyleofenergy-saving,cost-reducing,production-enhancingequipmentforaluminiumprofileprocessingenterprises,tomeetpresentmarketdemandsofaluminiumindustry,whichcanpreciselycontroltemperatureandautomaticallyquitfromheatingcontrollingsystemwhilethedie'stemperaturereachestheresetonewithextremelysmallpowerconsumption.Meanwhile,advancedseparatedmagneticenergyinductionheatingmethodisadoptedtoenhancethesafetyindexduringproductionandextendequipmentservicelife.一、与传统加热方式对比ComparedwithtraditionalHeatingOven挤压模具新旧加热方式对比表（模径200mm）Comparingtableofnewandoldheatingmethodforextrusiondie(diameter200mm)itemoldnewHeatingmethodElectricresistancewire,oilcoalorgasheatingboxHighlyeffectivemagneticenergyOperationmethodartificialHalfautomatic/automaticHeatingtime≥150minutes≈15minutesuniformityoftemperaturerisePartiallyoverheatingforalongtimeHeatingfrominsidetooutsidewithuniformityTemperaturecontrollingaccuracyUnstable,inaccuratestable、smalltemperaturedifferenceHeatingandthermalreservationtimeartificialCanbesetEnergyconsumptionlargesmallEnvironmentalinfluenceSmokeanddust,highenvironmenttemperatureNosmokeanddust,lowenvironmenttemperatureHeatingdevicearrangementfixedmovableDevicevolumeVerybigsmall比较项目原加热现用加热加热方式电阻丝、油、煤气发热箱高效磁能加热操作方式人工半自动/自动加热时间150分钟以上15分钟左右温升均匀度偏烧、长时间局部过烧内及表加热、加热均匀温度控制精度不稳定、不准稳定、温差小
