连铸辊长寿命技术研究李富帅（中冶连铸北京冶金技术研究院北京100081）摘要：本文通过对连铸辊失效机理的分析以及对不同冷却结构辊子温度场的计算，强调通过加强辊子的冷却，大幅度提高其热疲劳寿命的理念。在辊子温度场的计算过程中，运用有限元法实现辊子动态旋转、接触过程的模拟，得到了辊子“动稳态”下的温度场分布，为长寿命连铸辊的优化设计提供了一个有效的工具。关键词：连铸辊、热疲劳、温度场、有限元AStudyOnTechniqueForExtendServiceLifeofContinuousCastingRollLiFushuaiBeijingMetallurgicalTechnologyInstituteofCCTECEngineeringCo.,LtdAbstract:BasedonanalysisoffailurecausesofContinuousCastingRollanddetailedtemperaturefiledanalysisofContinuousCastingRollindifferentstructure,thepaperhasemphasizedtheconceptionthatExtendServiceLifeofContinuousCastingRollgreatlybyreinforcedcoolingroll.Inthecalculationoftemperaturefiledofroll,UsingFiniteElementMethod,havesimulatedthedynamicrotateofrollandthecontactbetweenstrandandroll,thispaperhavegotthetemperaturedistributionofrollinthenormalstate,andhaveprovidedaefficienttoolforp..
