设计一个年产300万吨合格连铸坯的转炉炼钢车间摘要

摘要由于市场对钢材的大量需求，现代化的炼钢设备都在向着大型化的方向发展，本设计主要是模拟建立一个现代化年产300万吨的中型炼钢企业，以满足市场对钢材的需求，促进经济的稳定发展。设计为氧气顶吹转炉工艺，转炉的公称容量为150吨，冶炼时间需要40分钟。其中，仅有16.5分钟时间用于实际的吹氧过程。其余时间（23.5分钟）为炉子装料、取样并检测钢液成分、以及测量钢液温度、出钢、倒渣等各过程所需时间之和。转炉的吹炼模式采用2吹2。车间设有1座RH精炼炉和2套板坯连铸机，预计年生产能力为300万吨良坯钢。本设计对物料平衡和热平衡，炉型的计算，炉外精炼，连铸以及烟气净化系统等做了详细的介绍。关键词：150吨氧气顶吹转炉；炼钢；连铸。AbstractBecauseofthehighdemandforsteelmarket,modernsteel-makingequipmenttowardthedirectionofbignessindevelopment,thisdesignismainlysimulationinliupanshuicitytobuildamodernyearlyproduces300tonsofmedium-sizedsteelmakingenterprise,tomeetthemarketdemandforsteel,andpromotesteadyeconomicdevelopment.Thedesignforarepresentativeofoxygenblowingthetopofeachfurnacefortheproductionof150tonsofliquidsteel,andsmeltingtimeis40minutes.Ofthese,only16.5minutesfortheactualoxygenblowingprocess.Theremainingtime(23.5minutes)forthestoves,filling,samplingandtestingofliquidingredients,andmeasuringthetemperatureofliquidsteel,steel,inverted,andotherresidueoftheprocessandtimerequired.Designofthescaleofproductionforthethree3milliontonsofoxygenBOF,oneRHrefiningandonesetofcontinuouscastingequipments,whichareexpectedannualproductioncapacityof3milliontonsofsteelbillet.Thedesignofthematerialbalanceandthermalbalance,thefurnaceshape,refining,continuouscastingandthefluegaspurificationsystem,adetailedintroductionwerefinished.Keywords:BOFof150tons;steelmaking;continuouscasting
