3000立方米高炉设计说明书

内蒙古科技大学本科生毕业设计说明书题目：天津原料条件下3000m3高炉本体设计及渣铁处理系统的设计学生姓名：学号：专业：班级：指导教师：内蒙古科技大学毕业设计说明书I摘要高炉喷煤是20世纪60年代开始大规模应用于钢铁工业生产的炼铁新技术。随着石油危机、环保和炼焦煤资源日益短缺等问题，高炉喷煤已不仅是高炉调剂的一项重要手段，同时还是弥补焦炭不足的主要措施。而且高炉喷煤是降低炼铁生产成本的有效途径。本设计结合包钢地区原料条件下和对目前国内外先进高炉喷吹工艺的学习。采用并罐直接喷吹形式的喷煤方式设计的2200m3高炉喷煤系统。系统设计包括高炉喷煤储运系统设计、高炉喷煤制粉系统设计、高炉喷煤喷吹系统设计、高炉喷煤安全设计。从而以价格低廉的煤粉部分替代价格昂贵而日趋贬值的冶金焦炭，使高炉炼铁焦比降低，生铁成分下降。增加效益。关键词：高炉喷煤；高炉；喷煤技术；内蒙古科技大学毕业设计说明书IIAbstractTheblastfurnacecoalisthe1960slargescaleapplicationsteelindustryproductionofnewiron-makingtechnique.Astheoilcrisis,environmentalprotectionandcokingcoalresourcesincreasinglyscarce,blastfurnacehasnotonlytheblastfurnaceiscoaladjustedaandalsoanimportantwaytomakeupforthelackofcokeormajormeasures.Andblastfurnaceironmakingistoreduceproductioncostcoaltheeffectiveway.ThisdesignwithBaotouareaofmaterialconditionandathomeandabroadandadvancedinjectionprocessofblastfurnacestudy.Theadoptionandcansofdirectinjectionfromofpulverizedcoalinjectionwayof2200m3designofblastfurnacecoalsystem.Systemofblastfurnacedesignincludingcoalstoragesystemdesign,blastfurnacecoalpulverizingsystemdesign,blastfurnacepulverizedcoalinjectionsystemdesign,blastfurnacesafetydesignofcoal.Andthelowpriceofcoalpowderpartlyreplaceexpensiveandmorelackofmetallurgicalcoke,maketheblastfurnaceironmakingcokeratereduce,pigironcostdown.Increasebenefits.Keywords：coalofblastfurnace，blastfurnace，injectiontechnology内蒙古科技大学毕业设计说明书III目录摘要........................................................................................................................IAbstract.................................................................................................................II第一章文献综述..........................................................................错误!未定义书签。1.1高炉冶炼概况及发展...........................................错误!未定义书签。1.1.1高炉生产主要经济指标技术................................................................11.1.2炉容大型化及其空间尺寸的发展........................................................21.1.3炉料向精料发展....................................................................................21.1.4提高鼓风温度........................................................................................21.1.5提高炉顶压力........................................................................................31.1.6富氧大喷吹............................................................................................31.1.7电子计算机的应用................................................................................31.2高炉本体..............................................................................................31.2.1高炉炉型发展........................................................................................错误!未定义书签。1.2.2五段式高炉炉型及炉型尺寸................................................................错误!未定义书签。1.3喷煤工艺的基本流程.....................................................................................51.3.1原煤储运系统........................................................................................61.3.2制粉系统................................................................................................61.3.3煤粉的输送............................................................................................61.3.4喷吹系统..............................................................................................71.3.5供气系统..............................................................................................71.3.6煤粉计量..............................................................................................71.3.7控制系统..............................................................................................81.4高炉烟煤喷...................................................................................................101.4.1高炉混喷煤的优越性............................................................................11内蒙古科技大学毕业设计说明书IV1.4.2外国高炉混喷烟煤工艺的发展............................................................111.4.3国内高炉混喷烟煤工艺的发展...........................................................12第二章炼铁工艺计算..................................................................错误!未定义书签。2.1已知高炉的冶炼条件......................................................................................142.2配料计算.........................................................................................................182.3高炉物料平衡计算......................................................................................202.4热平衡计算...................................................................................................242.4.1热收入................................................................................................242.4.2热支出...............................................................................................252.5高炉区热平衡计算..........................................................错误!未定义书签。2.5.1高炉区热收入...................................................................................282.5.2高炉区热支出...................................................................................292.6炼铁焦比的计算..............................................................
