辽宁科技大学本科生毕业设计第I页180吨转炉倾动机构设计摘要在转炉设备中的倾动机械是实现转炉炼钢生产的关键设备之一，炉体的工作对象是高温的液体金属，在兑铁水、出钢等项操作时，要求炉体能平稳地倾动和准确的停位。为获得如此低的转速，需要很大的减速比。转炉炉体自重很大，再加装料重量等，整个被倾转部分的重员要达上百吨或上千吨本设计说明书以鞍钢180吨转炉全悬挂倾动装置为借鉴，以倾动角度连续回转360度，倾动速度范围从0.1r/min~1.0r/min进行设计。主要内容包括：分别对转炉的空炉，炉液的重心进行计算；转炉倾动力矩的计算；电机的确定和传动比的分配；倾动机械及其传动件的设计（包括传动方案的选择，根据倾动力矩进行电动机的选择和校核，减速器的设计，主要零部件的强度校核）；抗扭缓冲装置的设计，此外，还进行了技术经济性分析。关键字:转炉;炼钢机构;倾动机械;倾动装置辽宁科技大学本科生毕业设计第II页180TonsOfConverterTitledHoldingMechanismDesignABSTRACTInconverterequipmentistorealizethetitledholdingmachineryconvertersteelmakingproductionofoneofthekeyequipment,furnaceworkobjectisthetemperatureoftheliquidmetal,confirmedthesteelinmetal,andwaitforanoperation,requirementscansmoothlytitledholdingfurnaceandaccuratestagnate.Toobtainsuchalowspeed,needagreatdealofthedecelerationthan.Theconverterfurnaceself-respectisverybig,installadditionalmaterialweight,thewholeisturnedoutofthepartoftheheavymembertoreachovertonsorthousandsoftonsofthisdesignspecificationsinangang180tonsofconverterforreferenceforthesuspensiontitledholdingdevice,titledholdingAnglecontinuousrotary360degrees,titledholdingspeedrangefrom0.1r/min~1.0r/mintocarryonthedesign.Themaincontentsinclude:totheemptyrespectivelyofconverterfurnace,thefurnacecalculatedthecenterofgravityofthefluid;Thecalculationoftorqueconvertertitledholding;Determinationofthemotorandthetransmissionratioofthedistribution;andTitledholdingmachineryandtransmissionpartsdesign(includingtransmissionschemechoice,accordingtothechoiceofthemotortorqueoftitledholdingandcheck,thedesignofthespeedreducer,themaincomponentsofstresstest);Thedesignofthebufferdevicetowrestresistant,inaddition,alsocarriedouttechnologyeconomyanalysis.Key:Theconverter;Steelmakinginstitutions;;Titledholdingmachinery;Titledholdingdevice.辽宁科技大学本科生毕业设计第I页目录摘要.......................................................................................................................................IABSTRACT...........................................................................................................................II1.绪论..................................................................................................................................11.1转炉炼钢发展历史.......................................................................................................11.2转炉炼钢生产技术.......................................................................................................21.3转炉倾动机构的作用...................................................................................................31.4本文研究的主要内容...................................................................................................32.方案选择与评述................................................................................................................42.1支承装置结构...............................................................................................................42.2倾动机构的结构形式...................................................................................................42.2.1倾动机构的选择原则.........................................................................................42.2.2倾动机构的配置形式.........................................................................................52.3传动系统结构形式.......................................................................................................52.4电机的选择...................................................................................................................62.5联轴器的选择...............................................................................................................62.6轴承的选择...................................................................................................................62.7耳轴的结构...................................................................................................................73转炉倾动机构电机的选择.............................................................................................83.1转炉空炉重量及重心位置的计算...............................................................................83.1.1炉壳部分重量及重心位置的确定.....................................................................83.1.2炉衬各部分重量及重心位置的确定...............................................................113.2炉内液体的重量和初始液面高度的计算.................................................................153.2.1炉内液体的重量的确定...................................................................................153.2.2初始液面高度的计算.......................................................................................163.3计算机计算炉液重心和倾动力矩.............................................................................163.3.1计算原理...........................................................................................................16辽宁科技大学本科生毕业设计第II页3.3.2输入原始数据..................................................................................................163.3.3计算过程（C语言程序见附录A）...............................................................183.4.1转炉电机所需功率：.......................................................................................193.4.2转炉过载校核
