冶金专业炼铁厂年产175万吨高炉毕业设计

河北联合大学轻工学院QINGGONGCOLLEGE,HEBEIUNITEDUNIVERSITY毕业设计说明书设计题目：设计一座年产生铁275万吨的高炉车间学生姓名：孟祥松学号：200915090113专业班级：09冶金1班学部：材料化工部指导教师：蒋武锋讲师2013年05月24日摘要摘要本设计是根据唐山地区条件设计的一个年产275万吨的高炉炼铁车间。整个车间的平面布置采用半岛式平面布置形式。设计的高炉有效容积是1982m3。其中高炉的炉衬设计方法采用的是均衡炉衬的方法，根据不同的冶炼条件砌筑不同的砖。上部采用的砖型有高砖，下部采用的是全碳砖炉底。冷却方式：炉身部分采用板壁结合的方式炉腰部分采用凸台冷却壁；炉缸和炉底采用光面冷却壁和水冷炉底结构。设计的热风炉采用传统改进型内燃式热风炉。蓄热式和燃烧室在同一炉壳内，中间用隔热墙隔开；采用眼睛型燃烧室。这部分同时包括热风炉各种设备和阀门的选取计算。上料系统采用的皮带机连续上料，同时增加了皮带的速度和宽度，满足高炉冶炼的要求。炉顶装料设备采用串罐式无料钟炉顶装料。喷吹系统增加了煤的数量，采用了单管路串罐式直接喷吹。煤气处理设备采用的是湿法除尘设备。所涉及的计算有高炉和热风炉尺寸的计算、高炉的物料平衡和热平衡计算以及热风炉风机的选择等。关键词：高炉；热风炉；湿法除尘；风机；无钟炉顶AbstractAbstractAblastfurnaceplantof2.75milliontonsproductannualwasdesigenedintheinthepaperaccordingtoTangshanareacondition.Thehorizontallayoutofthewholeplantispeninsulatypelayout.ThedischargeablecapacityoftheBFinthisdesignis1982m3.amongit,theBFliningadoptedequalizationliningmethodandwasmadeofaluminabrickandchayoteinupperofBFandallcarbonbrickinthebottomofBF.Thecoolingmethodswerebattenwallstyleinshaft,boss-coolingstaveinbosh,smoothcoolingstaveinhearthandwater-coolingstaveinbottomofhearth.Theair-stovewasmodifiedtraditionstyleofinternalcombustion.Thecheckerchamberandcombustionchamberwereinthesamefurnaceshellanddividedbyheatinsulationwall.Andthecombustionchamberwaseye-style.Furthermorethispartofthepaperincludedtheselectionofvariousequipmentsandvalves.ThechargingequipmentusedthebeltmachinetocontinuingsupplyingchargeandthebeltvelocityandwidthwereincreasedinordertomeettheBFmeltingneeds.Thefurnaceroofequipmentusedstringpotstyleofnon-bellfurnaceroof.Injectionsystemincreasedamountofcoalandusesinglevalvelinestingpotdirectinjection.Thegastreatingsystemusedhydrofilterequipment.ThecomputesinthepaperhavesizeofBFandair-stave,chargebalance,heatbalanceandfanofair-stavechoice,etc.Keyword:blastfurnace,air-stove,hydrofilter,fan,non-bellfurnaceroof目录I目录摘要.............................................................................................................................IAbstract.........................................................................................................................II第一部分设计说明书..................................................................................................1引言............................................................................................................................2第1章绪论..................................................................................................................31.1概述.................................................................................................................31.2高炉生产主要经济技术指标....................................31.3高炉冶炼现状及其发展........................................41.4本设计采用的新技术..........................................5第2章高炉车间设计..................................................................................................62.1厂址的选择..................................................62.2高炉炼铁车间平面布置应遵循的原则............................72.3车间平面布置形式............................................7第3章高炉本体设计..................................................................................................83.1高炉数目及总容积的确定......................................83.2炉型设计....................................................93.3参数.......................................................113.4炉衬设计及高炉基础.........................................123.4.1高炉炉基的形状及材质..................................123.4.2高炉炉底和各段炉衬的选择、设计和砌筑..................133.5高炉冷却及钢结构.........................................................................................143.5.1炉底冷却型式选择......................................143.5.2高炉各部位冷却设备的选择..............................153.5.3高炉供水量、水压的确定................................153.5.4风口数目及直径........................................173.5.5铁口..................................................173.5.6炉壳及钢结构确定......................................17第4章原料系统........................................................................................................194.1焦矿槽容积的确定...........................................194.1.1贮矿槽和附矿槽的布置、容积及数目的确定................194.1.2焦矿槽的布置、容积及数目的确定........................204.2槽上、槽下设备及参数的确定.................................204.2.1槽上设备..............................................204.2.2槽下设备及参数选择...................................204.3皮带上料机能力的确定.......................................20第5章送风系统........................................................................................................225.1高炉鼓风机的选择...........................................225.1.1高炉入炉风量..........................................225.1.2鼓风机风量............................................225.1.3高炉鼓风压力..........................................225.1.4鼓风机的选择..........................................23目录II5.2热风炉.....................................................235.2.1热风炉座数的确定......................................235.2.2热风炉工艺布置........................................235.2.3热风炉型式的确定......................................235.2.4热风炉主要尺寸的计算..................................235.2.5热风炉设备.................
