Numerical Simulation of Inclusion Removal in Tundish with Babbling Curtain and Electromagnetic Field

摘要：

　　According to the structure and the operating parameters of tundish at some plant,the inclusion removal in tundish with babbling curtain and electromagnetic field was simulated by numerical calculation method,and based on the optimization,the actual-service test were put into effect.The results show that: compared with the bubble-gap soft filter of multiple gas curtains,the composite filter with traveling wave magnetic field and bubbling curtains in the tundish can further improve the inclusion removal rate.A large number of small particle inclusions are removed primarily by bubble flotation through the assisting of electromagnetic field.While the removal rate of inclusions which diameters are less than 50μm is increased by 48%,especially the removal rate of inclusions which diameters are less than 20μm is increased by 76%.The efficacy of the composite filter of traveling wave magnetic field and bubbling curtain is obviously.
