攀枝花学院本科毕业设计（论文）角钢孔型设计二〇一一年六月攀枝花学院本科毕业设计（论文）摘要I摘要角钢属建造用碳素结构钢，是简单断面的型钢钢材，主要用于金属构件及厂房的框架等。本论文通过对现有资料的研究及分析，选择了角钢初轧、切分轧制、精轧三个阶段的轧制孔型系统及其各个孔型系统参数的确定方法，并针对角钢轧制中蝶式孔型系统共用性差的缺点，采用了用按最大厚度来设计此规格的角钢来克服这个缺点。关键字角钢，孔型系统，孔型设计攀枝花学院本科毕业设计（论文）ABSTRACTIIABSTRACTAngleironbelongstocarbonstructuralsteelinconstruction，itisakindofsimplesectionsteel,mainlyusedformetalstructuresandplantframeworketc.Thispaperchoosestherollingpasssystemanditsparametersofeachmethodfordeterminingthepasssystemintheinitialrollingangle,Slitrolling,rollembossingthreestages,throughresearchingandanalysistheavailableinformation,andforshortcomingsofpoorinteroperabilityinbutterflypasssysteminrollingangle,itadoptsthemeansofdesigningthespecificationsoftheanglebythemaximumthicknesstoovercomethisshortcoming.Keywordsanglesteel，PassSystem，PassDesign攀枝花学院本科毕业设计（论文）目录1目录摘要·································································································IABSTRACT··························································································II1绪论···························································································11.1概述························································································11.2生产工艺简介··············································································12孔型系统的演变·············································································32.1在开口蝶式孔型中用自由宽展法轧制····················································32.1.1开口蝶式孔型系统的优点····························································32.1.2开口蝶式孔型系统的缺点····························································32.2在闭口蝶式孔型中用限制的变形宽展法轧制············································42.2.1闭口蝶式孔型系统的优点····························································42.2.2闭口蝶式孔型系统的缺点····························································42.3角钢轧制孔型系统的发展方向····························································43孔型系统的设计方法··································································...
