Modelling segregation during equiaxed dendritic growth : application to the solidification of steel
Modélisation de la ségrégation lors de la croissance dendritique équiaxe : application à la solidification de l'acier
To optimize continuous casting process of heavy steel plates at Sollac-Dunkerque, a metallurgical study of the effect of electromagnetic stirring, in the secondary cooling zone, was carried out. It was shown that stirring increases intergranular segregation around equiaxed crystals. Based on these metallurgical results, a physical model of equiaxed dendritic growth was developed. The specific feature of this solidification model is to take into account the effect of crystals morphology on intergranular segregation. Calculations were performed for an alloy Fe - 1.5 % Mn at different cooling rates in a range of 0.02 to 0.5 °C/s. Typical cooling curves with recalescence were obtained for equiaxed solidification. A mathematical simulation to analyse the effect of stirring on equiaxed growth has also been made.
