dcterms:description
Continuously cast round blooms from vanadium microalloyed steel denoted as 25CrMo4 type are very sensitive to internal defect creation during casting. Further propagation of internal cracks is affected by suboptimal heating preceding the hot rolling process. FEM offers powerful tool for simulation of the temperature gradients and stress-strain behavior. In this paper it is demonstrated that proper selection of FEM model is essential to get trustworthy results corresponding with practical observations. It is possible to find optimum between two contradictory requirements – acceptable computation time severity and trustworthy results, if the simple model is compared with experimental data and/or more sophisticated models.
