Wood Metal Experiment of Swirling Flow S

The interest in flow pattern optimizations in continuous casting molds is increasing, driven by stricter quality and productivity demands. This study, initiated as a joint effort in 1997, investigates the effectiveness of swirling flow generated by submerged entry nozzles for enhancing mold flow patterns. The primary objective is to elucidate the conditions under which swirling flow can promote upward flow along the mold wall, aiming to improve the surface and internal quality of cast billets. Our methodology involved a controlled wood metal experiment utilizing an experimental apparatus that included a submerged entry nozzle, temperature control mechanisms, and electromagnetic stirring coils. We measured the flow rates and characterized the behavior of the swirling flow with precise instrumentation. Results indicated that the single port swirling flow nozzle successfully established a dominant upward flow that mitigated the challenges of inclusion flotation and segregation within the billets. The findings suggest that enhancements in flow patterns through swirling flow techniques can significantly enhance casting quality in industry applications.
