盘管组件论文―陆杉杉

常州工程职业技术学院——毕业设计（论文）1毕业设计论文（2011届）论文题目：1000大卡有机热载体加热炉盘管组件焊接工艺设计系部：焊接技术及自动化作者姓名：陆杉杉指导老师：魏守东完成日期：常州工程职业技术学院——毕业设计（论文）2摘要：有机热载体锅炉又称导热油炉。近几年来，随着我国国民经济的发展和加入世贸组织，该型锅炉的市场需求量越来越大，特别是在化工、纺织、印染、材料加工等行业，其用途越来越广。有机热载体锅炉的最大特点是低压高温，即在较低的工作压力下获得较高的介质温度，且介质仍为液相，不发生相变，这是其他类型的锅炉所不及的。作为热载体炉的核心盘管组件，其焊接质量的好坏将直接影响到热载体炉的热交换能力，且对安全造成一定的威胁，根据图纸的要求及规定，炉管对接应采用氩弧焊，容易控制焊缝成型及实现单面焊双面成型。圆钢使用的是Q235A材料，与炉管焊接，都是低碳钢材料，焊接性良好，几乎可以选择所有的焊接方法，并能保证焊接接头的良好质量，焊条电弧焊操作方便、使用灵活，适用于炉管与圆钢的焊接。选用合适的焊接材料、焊接工艺参数及工艺措施，研究焊缝对焊接工艺评定的要求及焊接工艺评定报告的引用，确定锅炉焊接对焊工技能及焊工资格要求，编制合适的焊接工艺规程。对焊缝的成形和焊接质量进行分析，确定焊接工艺设计的可行性。关键词：盘管炉管圆钢焊接性焊接工艺Abstract：Organicheatcarrierfurnacealsoknownastheheatconductionoilstove.Inrecentyears,asChina'snationaleconomicdevelopmentandtheWTO,theboilerofthegrowingmarketdemand,particularlyinthechemicalindustry,textile,printinganddyeing,materialsprocessingindustries,itsusehasbecomeanincreasinglywidespread.Organicheatcarrierfurnacebiggestcharacteristicsoflow-temperature,thatis,atthelowworkingpressureforhighertemperature,andthemediaisstillliquid,withouttransformation,thisisanothertypeoftheboiler.Ashotcarrierstovecorecoilcomponents,weldqualityisgoodorbadwilldirectlyaffecttheheatcarrierfurnaceheatcapacity,andonthesafetyofthreat,sothestudyofthecoilAssemblyof常州工程职业技术学院——毕业设计（论文）3structuralfeaturesandweldingprocessisessential.Accordingtothedrawingsandthefurnacepipebuttshoulduseargon-arcwelding,easytocontroltheweldingseamformingandrealizationofsingle-sidedmoldingofwelding.RoundsteelusingQ235Amaterials,andfurnacepipewelding,ismildsteelmaterial,weldabilitygood,almostalloftheweldingmethodsandcanguaranteethegoodqualityofweldedjoints,arcweldingeasyoperation,flexible,suitablefortubesandroundsteelwelding.Selectionofappropriateweldingconsumables,weldingparametersandtechnicalmeasuresofwelds,studyonweldingprocedurequalificationrequirementsandweldingtechnologyassessmentreportareferencetodeterminetheboilerandweldingonweldingskillsandwelderqualificationrequirements,prepareappropriateweldingprocedurespecification.Ontheformingandweldingseamqualityanalysis,todeterminethefeasibilityoftheweldingprocessdesign.。Keywords:traystoveroundbarsteeshuttingtogetherbondingtechnology目录1引言...............................................................................................................................................41.1有机热载体炉的发展与现状...........................................................................................41.2课题选择的背景................................................................................................................52有机热载体炉...............................................................................................................................52.1有机热载体炉的定义.......................................................................................................52.2有机热载体炉的分类.......................................................................................................53盘管组件的结构工艺性分析及制造工艺流程............................................................................53.1盘管组件结构的组成.......................................................................................................5常州工程职业技术学院——毕业设计（论文）43.2盘管的作用.......................................................................................................................53.3盘管的结构工艺性分析....................................................................................................53.3.1盘管结构工艺性分析及分析的目的....................................................................53.3.2盘管结构图样分析................................................................................................53.3.3盘管结构工艺性分析的内容................................................................................63.4盘管组件的生产工艺流程...............................................................................................63.4.1盘管的生产工艺流程...........................................................................................63.4.2盘管组件的生产工艺流程..............................................................................74盘管组件的焊接.........................................................................................................................104.1材料的焊接性.................................................................................................................104.1.1Q235A的焊接性..................................................................................................104.1.220钢的焊接性.................................................................................................114.2盘管的焊接.....................................................................................................................124.2.1焊接方法、焊接材料及焊接参数的选择...................................................124.2.2焊接工艺评定及焊工资格要求.....................................................................134.2.3焊接工艺参数..................................................................................................134.4盘管与圆钢的焊接......................................................................................................144.4.1焊接方法，焊接材料及焊接参数的选择.................
