The quality of half products in steel manufacturing is influenced significantly by the cooling conditions experienced by molten steel as it transitions through exchangers and molds. This study aims to demonstrate how modifications to nozzle geometry can impact flow structure and particle behavior in the continuous casting mold. We conducted numerical simulations to assess the effects of different nozzle designs on the formation of a solidified crust that adequately withstands the ferrostatic pressure. The results reveal that an inclined nozzle configuration enhances the recirculation zone, thus increasing the residence time of particles and promoting a thicker solidified crust. The use of well-designed geometric shapes for nozzles was found to advantageously affect the behavior of particles such as Al2O3. The numerical tests confirm that optimizing nozzle design can have a crucial role in minimizing macro-inclusions in the molten steel and improving overall steel cleanliness. This research contributes valuable insights into the design and efficiency of continuous casting operations.
