Three-dimensional transient temperature field of work roll in hot tandem rolling

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.
