Abstract

In order to study the coupled effect of rolling deformation, heat transfer and water cooling on microstructure formation of a steel strip, a multiscale and multiphysical FE-model is developed. The deformation state and temperature distribution of the steel strip after the last rolling pass are required to calculate the final microstructure. The sub-model predicting final microstructure on the steel strip after accelerated water cooling is implemented numerically. Final phase fractions are calculated with the Johnson-Mehl-Avrami-Kolmogorov equation for different parts of the object, taking into account non-uniform temperature distribution.
