300平米烧结机烧结厂设计.

武汉科技大学本科毕业设计I摘要烧结矿在高炉炼铁生产中是很重要的一种含铁原料，它的质量好坏和产量的高低直接影响高炉的冶炼效果。因此，设计一个合理的烧结工艺流程是非常重要的。在整个设计过程中吸收了很多国内外先进厂家的经验和技术，根据所学的专业知识，设计一台300m2的烧结机。其技术指标为年产烧结矿307.48万吨，R=1.8，TFe≥57%，成品矿粒度50-5mm，转鼓指数≥70%。本设计说明书中对所设计的烧结厂工艺进行了简要的介绍，并进行了物料平衡及工艺流程的计算，设备选择计算，确定了含铁原料、熔剂、燃料等需要量，并选择了与之相应的设备配置。全文分为：绪论；原料、熔剂和燃料；生产规模，工作制度及产品方案；烧结工艺流程及物料平衡；烧结物料平衡与热平衡计算；环境保护与综合利用六个部分。本设计中，充分考虑了设备自动化控制及环境保护等方案的需要，选择了当前先进的工业设备。在计算基础上又绘制了图纸说明并编写了设计说明书。关键词：烧结厂设计；工艺流程；自动化控制；环境保护武汉科技大学本科毕业设计IIAbstractInblastfurnaceironmaking,thesinterisanimportantironmaterial.Theproductivityandqualityofthesinterhavedirectlyeffectonblastfurnaceironmaking.Soitisveryimportanttodesignasensiblesingteringcraft.Inthedesignprossess,Someadvancedexperienceandtechnologyofdomesticandforeignmanufactureshasadopted.Accordingtothestudyofexpertise,therequirementistodesigna300m2ofsinteringcraft.Thetechnicalindicatorsisfollowing:theyearquantityofsinteris307.48tenthousandton,R=1.8,TFe≥57%,drumindexisnolessthan70%,finishedminesizeisfrom50mmto5mm.Itisintroducedtheprocessofthesinteringplantinthedesignspecification.Andcalculationinmaterialbalance,processandequipmentselection,determinetheferrousmaterials,flux,fuelandotherrequirements,andselectionofthecorrespondingfitnessequipmentconfigurationaredisplayed.Thethesisiscomposedofsixsections:introduction;materialofironores,fluxes,flues;capacity,workingrulesandproductionprogramofthesinterplant;processandmaterialbalancecalculation;sinteringmaterialbalanceandthermalequilibriumcalculation;environmentprotectionandcomprehensiveutilization.Theequipmentautocontrolandenvironmentalprotectionarefullyconsideredinthedesign.Thecurrentadvancedcraftequipmentwasused.Onthebaseofcalculation,thedrawingsweredrawnandthedesignspecificationwascomplied.Keywords:Sinteringplantdesign;Technicalprocessing;Automatedcontrol;Environmentalprotection;武汉科技大学本科毕业设计III目录前言...................................................................................................................................11绪论...................................................................................................................................21.1烧结厂设计目的...................................................................................................21.2烧结厂设计依据及概况.......................................................................................21.3烧结厂设计要求...................................................................................................21.4厂区概况及厂址特点...........................................................................................31.4.1厂区概况.....................................................................................................31.4.2厂址特点.....................................................................................................31.5设计特点...............................................................................................................32原料、熔剂和燃料...........................................................................................................42.1概述.......................................................................................................................42.2含铁原料...............................................................................................................42.3熔剂.......................................................................................................................42.4燃料.......................................................................................................................52.5配比确定...............................................................................................................63生产规模，工作制度及产品方案...................................................................................73.1主要技术经济指标确定.......................................................................................73.1.1作业率确定.................................................................................................73.1.2利用系数确定.............................................................................................73.1.3其他经济技术参数.....................................................................................73.2生产能力确定.......................................................................................................83.2.1日生产能力.................................................................................................83.2.2小时生产能力.............................................................................................83.3工作制度...............................................................................................................83.4产品方案...............................................................................................................83.5烧结厂厂房布置及设备布置...............................................................................93.5.1烧结厂设备配置原则.................................................................................93.5.2工艺建筑配置原则.....................................................................................93.5.3原料车间配置.....................................
