The generation of swirling flow in a submerged entry nozzle is a crucial technique for stabilizing flow in continuous casting molds. This study aims to investigate the effectiveness of swirling flow technology in submerged entry nozzles, focusing on slab casting. The methodology includes designing swirling-flow submerged entry nozzles equipped with swirl blades, conducting water model experiments, and performing computational fluid dynamics (CFD) simulations to optimize nozzle geometry and flow stability. These innovations enable improved surface quality of cast products and increased casting speed while utilizing only the energy from the head difference between the tundish and mold. Results demonstrate that the application of this technology to industrial slab casters significantly enhances the flow conditions during the casting of ultra-low carbon steel used for galvanized automotive panels, thereby achieving high-quality outcomes without the need for expensive electromagnetic devices. Overall, this research underscores the potential of swirling-flow technology in enhancing continuous casting processes, highlighting its energy-saving capabilities and practical implementation in existing casting machines.
