Numerical Study of the Molten Steel Flow and Inclusion Behavior in the SEN and Mold when Using a Half Type EMSFG
The influence of the swirl flow on the fluid flow and inclusion behavior in the submerged entry nozzle(SEN)and mold was studied.This swirl flow was generated by using a half type electromagnetic swirl flow generator(EMSFG).The results show that an imbalance flow was generated at the EMSFG inlet.However,the imbalanced flow cannot cause a negative influence on the continuous casting process.Moreover,compared to the no swirl case,the penetration depths of the main stream of molten steel from the SEN outlet was reduced for a half type EMSFG case.In addition,from the view point of inclusion removal to the meniscus,it was found that a swirl flow greatly promotes a separation of inclusions to the mold flux.
