| Abstract Scope |
Microsegregation plays a critical role in the solidification behavior of continuously cast steel slabs, affecting internal quality and downstream performance, including homogeneity of metallurgical properties. This study applies mathematical models to simulate heat transfer, solidification and microsegregation during continuous slab casting. A two-dimensional multiple moving slice-based model is used to compute temperature fields and determine the position of the liquidus and solidus fronts. The microstructure is further characterized by calculating secondary dendrite arm spacing (SDAS). The calculated temperature and cooling rate histories are validated via comparison with thermographic measurements of surface temperature between rolls in the secondary cooling zone. Simulated SDAS and microsegregation are compared with composition profiles of carbon, manganese and other critical alloying elements measured through Electron Probe Microanalysis (EPMA) in the columnar zone of the cast steel slabs. This work is an important step towards the prediction of centerline macrosegregation and other internal defects, such as cracks. |
