攀枝花学院本科毕业设计（论文）REF_Ref356734910\h\*MERGEFORMAT摘要PAGE\*MERGEFORMATII摘要当前，钢铁冶金行业遭遇到全球性的原料价格上涨，焦炭、矿石的价格涨幅惊人，冶炼成本普遍提高，我国钢铁产业过剩等因素，给高炉炼铁业带来更大的发展困难。所以，高炉喷煤已成为炼铁系统工艺结构优化、能源结构变化的核心，是企业能否在激励的市场竞争中取胜的关键。本文针对高炉喷煤采用美国HONEYWELL公司的TPS(TotalPlantSolution)DCS技术设计了高炉系统喷吹站的控制系统，对各个检测点的参数进行数据收集、处理，然后通过执行机构对系统各个操作进行自动控制。系统功能强大、稳定可靠、抗干扰能力强、耐恶劣环境、界面友好。在实际运行过程中，具有学习掌握快，易于操作，硬件侦测功能强，查找故障点迅速、准确等优点。获得了较好的应用效果。关键词高炉喷吹，DCS，控制攀枝花学院本科毕业设计（论文）REF_Ref356734886\h\*MERGEFORMATABSTRACTABSTRACTAtpresent,theironandsteelmetallurgyindustrysufferedaglobalcommodityprices,coke,ironorepricesweresurging,smeltingcostrisegenerally,suchfactorsastheexcessironandsteelindustryinChina,bringstotheblastfurnaceironmakingindustrygreaterdevelopmentdifficult.So,intheblastfurnacecoalinjectionhasbecometheironmakingsystemofprocessstructureoptimization,energystructurechangecore,istheenterprisecanintheincentivemarketcompetitiontowinthekey.Blastfurnacecoalinjection,thispaperadoptstheUnitedStatesHONEYWELLTPS(TotalPlantSolution)DCStechnology,designedtheinjectionintheblastfurnacesystemofstationcontrolsystem,datacollection,processingparametersofeachtestingpoint,andthenthroughtheactuatortoautomaticcontrolsystemeachoperation.System,powerful,stableandreliable,stronganti-interferenceability,resistancetobadenvironment,friendlyinterface.Intheactualoperationprocess,learningtomasterquickly,easytooperate,stronghardwaredetectionfunction,findthefaultpointquicklyandaccurately,etc.Obtainedthegoodapplicationeffect.KeywordsInjectionintheblastfurnace，DCS，control攀枝花学院本科毕业设计（论文）目录PAGE\*MERGEFORMATIV目录TOC\h\z\t"标题1,1,标题2,2,标题3,3"HYPERLINK\l"_Toc357016203"摘要PAGEREF_Toc357016203\hIHYPERLINK\l"_Toc357016204"ABSTRACTPAGEREF_Toc357016204\hIIHYPERLINK\l"_Toc357016206"1绪论PAGEREF_Toc357016206\h1HYPERLINK\l"_Toc357016207"1.1高炉炼铁的介绍PAGEREF_Toc357016207\h1HYPERLINK\l"_Toc357016208"1.2高炉喷煤技术PAGEREF_Toc357016208\h3HYPERLINK\l"_Toc357016209"1.3高炉喷煤的意义PAGEREF_Toc357016209\h3HY
