On Modelling Parasitic Solidification Du

Continuous casting (CC) is one of the most important processes of steel production; it features a high production rate and close to the net shape. The quality improvement of final CC products is an important goal of scientific research. One of the defining issues of this goal is the stability of the casting process. The clogging of submerged entry nozzles (SENs) typically results in asymmetrical flow and can lead to significant defects in the final product. This study aims to model and analyze the parasitic solidification that occurs due to heat loss in the submerged entry nozzle region of the continuous casting mold. To achieve this, we employed a combined 3D and 2D hybrid model to simulate the thermal and fluid dynamic behavior during the casting process. The results indicate that the proposed model provides a comprehensive understanding of the thermal gradients and flow patterns in the SEN region, significantly contributing to the prediction of solidification behavior and improving the overall stability of the CC process. This research establishes a foundation for further investigations into enhancing the quality of steel production in continuous casting systems.
