Finite Element Analysis of Temperature and Crown of Rolls in Hot Strip Rolling
In this paper a three-dimensional numerical computation on temperature and crown of rolls in hot strip rolling was evaluated based on finite element method and parallel computation technology with multiple CPUs. A comparison between calculated results and actual data collected from rolling mills was presented, which indicated the high accuracy of the model. The calculated results indicated that a significant impact in thin layer of work roll surface was brought by thermal load, while much weaker in the core. Furthermore, the temperature field and thermal crown of hot mill work rolls would reach a stabilized condition only when several rolling cycle be finished.
