This study allowed us to check that our simulation is able to describe accurately the influence of different process parameters (like casting speed, cooling strategy, machine design...) on the slab bulging. Even if the results must be confirmed quantitatively by bulging measurements, we can compare the different machines available in ARCELOR Flat Carbon Steel Sector in order to define the optimal metallurgical routes. Our final objective consists in being able to predict the formation of axial segregation according with the steel grade and the process conditions. It will be useful for instance to define the adequate soft reduction. To reach this goal, a more accurate description of the mushy zone is developed and will be coupled to the present modeling [5]. Moreover, damage modules for the mushy zone and for the solid phase will be introduced to predict the formation of cracks.
