毕业设计论文年产20万吨铝锭300kA预焙阳极铝电解车间设计摘要当今的铝电解工业正在向着槽容量大型化发展。大型预焙阳极铝电解槽上通过的强大电流会产生强大的磁场,磁场与电解质及铝液中的电流相互作用产生强大的电磁力,使铝液发生循环流动。这不仅会降低电流效率,也给生产操作带来一定困难。铝液流场分布的好坏对电流效率、吨铝电耗、阳极消耗、槽寿命、阳极效应系数等生产指标有着重要影响。因此,对铝液流场进行仿真具有重要的研究意义和实用价值。本文针对不同槽膛内形计算出相应的铝液流场。总结归纳300kA铝电解槽铝液流场的分布规律,并分析产生各种结果的原因。这些结论可以为铝电解槽的生产操作和优化设计提供理论依据。关键词：300kA；铝电解槽；双阳极；大面五点进电；Thedesignof300kApre-bakedanodeelectrolyticworkshopwithanannualoutputof200,000tonsofaluminumingotsAbstractTheelectrolyticaluminumindustryistowardsthedevelopmentoflargescaletankcapacity.Largescaleprebakedanodealuminumelectrolytictankbythestrongcurrentswillgenerateastrongmagneticfield,magneticfieldandtheelectrolyteandaluminumliquidinthecurrentinteractionsgeneratepowerfulelectromagneticforce,sothatthealuminumliquidcirculatingflow.Thiswillnotonlyreducethecurrentefficiency,butalsobringsomedifficulties.Thequalityofaluminumliquidflowfielddistributiononcurrentefficiency,energyconsumption,tonsofaluminumanodeconsumption,servicelifeofthecell,theanodeeffectcoefficienthasanimportanteffectontheproductionindex.Therefore,itisverysignificanttoresearchAluminumliquidflowbysimulating.Accordingtodifferentslotboreshapetocalculatetheflowfieldofmoltenaluminumtosummaryof300kAaluminumelectrolyticaluminumliquidflowdistributionandanalysevariousresults.Theseconclusionscanprovidealuminumelectrolyzerproductionoperationandtheoreticalbasisforoptimaldesign.Keywords:300kA；aluminiumelectrolysiscell；Doubleanode；Beddingfacefiveintoelectricity目录TOC\o"1-3"\h\z\uHYPERLINK\l"_Toc327255043"摘要PAGEREF_Toc327255043\h1HYPERLINK\l"_Toc327255044"AbstractPAGEREF_Toc327255044\h2HYPERLINK\l"_Toc327255045"1绪论PAGEREF_Toc327255045\h1HYPERLINK\l"_Toc327255046"1.1铝电解工业的概述PAGEREF_Toc327255046\h1HYPERLINK\l"_Toc327255047"1.2现代铝电解技术PAGEREF_Toc327255047\h1HYPERLINK\l"_Toc327255048"1.3国内外铝工业现状与发展PAGEREF_Toc327255048\h3HYPERLINK\l"_Toc327255049"1.3.1国外铝工业的现状PAGEREF_Toc327255049\h3HYPERLINK\l"_Toc327255050"1.3.
