Abstract
An existing thermomechanical finite‐element model of the hot rolling process is used to simulate the structure evolution in the strip. The equations which describe the grain‐size variations during the hot deformation are implemented in the model. The local values of temperatures, strain rates and strains are used in calculations, allowing the determination of the grain‐size distribution across the strip. The results of calculations carried out for the seven‐stand hot‐strip mill are presented in this paper.
