镁质耐火材料毕业设计说明书

I摘要本设计主要阐述了年产3.5万吨镁质耐火材料厂在设计中的重大问题以及方案的选择。首先，根据设计要求，设计原则，产品的种类（镁砖，镁铝砖，镁铬砖）及工厂的规模和生产方法，确定出生产的工艺过程，原料配比和颗粒的组成，各个车间的工作制度等。其次，进行物料平衡计算，主机平衡计算，根据计算结果进行设备选型。再根据设备在工厂中的安装要求及检修要求进行车间房布置。再次根据主机设备的需要对辅助设备进行选择。选择出合理的辅助设备并且确保主机设备正常高效运行。接着，对初步设计完成后的每个车间视其自身的特点进行合理的技术经济编制。最后，对设计中遗留的的问题进行了讨论。另外本设计中穿插有设备的外形尺寸图和工艺布置图，便于阅读和理解。关键词：工艺设计,镁砖,镁铝砖,镁铬砖IIAbstractThisdesigndescribesthemajorissuesofanannual35,000tonsoutputofmagnesiarefractoriesplantinthedesignmainlyandexplainedchoicesoftheprogram.First,accordingtodesignrequirements,designprinciples,producttype(brick,magnesiabrick,magnesia-chromebrick),theplantsizeandproductionmethods,itistodeterminetheproductionprocess,theproportionandcompositionofparticles,eachworkshopworksystemandsoon.Second,itistoworkoutthematerialbalance,andthehostbalance.Andthen,accordingtotheresult,itismatchingtheequipmenttypeanditisarrangingthefactoryaccordingtoinstallationofrequirementandexaminationinthefactories.Afterthat,itistodrawupthereasonabletechnologyandeconomyduetotheeachworkshop'sselfcharacterafterfinishingthefirstdesign.Finally,itistodiscussthemissingissuesofdesign.Moreover,therearepapersofequipment'sappearanceandarrangementinthedesign.Itisconvenienttoreadandunderstand.Keywords:processdesign,Magnesiabrick,Magnesiumaluminumbrick,MagnesiachromebrickIII目录1.文献综述........................................................11.1原料.........................................................11.1.1镁石.....................................................12.结构与形态....................................................21.1.2镁砂.....................................................31.2各种砖的介绍.................................................31.2.1镁砖......................................................31.2.2镁铝砖....................................................41.2.3镁铬砖....................................................51.3结合相.......................................................61.3.1硅酸盐....................................................61.3.2镁的氧化物和铁酸盐........................................61.3.3尖晶石结合物..............................................61.4发展前景.....................................................72设计原始数据及资料参数..........................................81.1设计题目.....................................................81.2规模及产品方案...............................................81.3设计参数.....................................................81.4主要材料及动力来源..........................................101.5设计的原则和要求............................................103生产方法和工艺流程..............................................113.1概述........................................................113.2镁质耐火材料的原料..........................................113.3制品的使用质量要求及标准....................................133.4提高产品质量的途径..........................................153.5直接结合....................................................163.6生产方法的选择..............................................174工艺计算........................................................224.1物料平衡计算的目的..........................................22IV4.2物料平衡计算................................................224.2.1计算过程说明............................................224.2.2各种砖型物料平衡计算....................................224.3主机设备选型...............................................344.3.1主机平衡计算............................................344.4原料仓库、料仓的计算........................................424.4.1原料仓库.................................................424.4.2桥式抓斗起重机搬运能力及计算.............................434.4.3成品仓库的面积确定.......................................454.4.4供料仓计算...............................................455热工计算........................................................505.1隧道干燥器的选型计算........................................505.1.1隧道干燥器数量的计算.....................................505.1.2干燥车数量的计算.........................................505.2隧道窑选型计算..............................................515.2.1窑的规格和台数的确定.....................................525.2.2窑车数量的确定...........................................536辅助设备选型....................................................546.1给料、计量设备..............................................546.2输送设备....................................................546.3除铁设备....................................................557车间工艺布置....................................................567.1工艺布置一般要求............................................567.2破粉碎车间的布置............................................577.3粉碎、磨碎混合工段..........................................577.3.1工段的布置...............................................577.3.2圆锥破碎机的布置........................................577.3.3管磨机的布置............................................577.3.4斗式提升机与筛分设备的布置..............................587.3.5混合设备的布置..........................................587.4成型车间的布置..............................................587.5干燥、烧成车间布置..........................................58V7.6成品库布置..................................................608技术经济指标....................................................61总结....................................................
