摘    要:考虑水冷、空冷、摩擦热和变形热以及工作辊与轧件接触热传导等动边界条件,采用有限差分法,建立了热连轧工作辊三维瞬态温度场分析计算模型。使用该模型实现了对工作辊温度的动态分析和精确计算,预测工作辊非稳态轧制时的瞬态温度分布、稳态温度场和终轧后空冷时的温度场。

关 键 词:工作辊  热连轧  轧件  空冷  水冷  轧制  摩擦热  三维  动边界  稳态温度场

Abstract:Comprehensivelyconsideringsuch dynamic boundary conditionsaswater cooling, aircooling, friction heat, deformation heat, and heat conduction between work roll and strip and so on, the analysis-calculation model of strip three-dimensional transient temperature field of work roll in hot tandem rolling is established with Finite-Difference-Method. So dynamic analyses and precise calculation can be realized for work roll's temperature. Then those can forecast work roll's transient temperature distribution while unsteady rolling, steady temperature field and the temperature field while air cooling after stopping rolling.
Keywords:hot tandem rolling  work roll  temperature field  finite difference method  dynamic boundary condition
