5th International Conference on Advances in Solidification Processes (ICASP-5) 5th International Symposium on Cutting Edge of Computer Simulation of Solidification, Casting and Refining (CSSCR-5)

DISTEMP solidification numerical model of the continuous casting steel has been a useful tool to explain billet surface and internal quality at Sidenor steel company. Work has been carried out along the years to adjust the appropriate heat transfer coefficients in the mould and secondary cooling to get a reliable description of the CC billet solidification. The numerical model has assisted to explain the influence of casting parameters on the formation of different defects in the CC process as the billet surface cracks for microalloyed steel grades; intercolumnar cracking for high temperature interval steel grades or the formation of central pipe/segregation for high carbon bearing steel grades. The solidification model has helped to find the optimum casting parameters to improve as cast semis quality
