AbstractA mathematical model was developed to analyze the transient three-dimensional and three-phase How in an argon gas bottom stirring ladle with one porous plug. Multiphase volume of fluid (VOF) method was used to simulate the kinetic behaviors of slag layer. Numerical results make the transient phenomena recur: when argon gas is injected into molten steel in a ladle, gas rising passage is formed near the plug. and then bubbles are created in the interior of molten steel; the rising gas bubbles impinge the slag intermittently and breakthrough the slag layer to create the slag eye. Simultaneously, the wave at interface of slag steel formed and wave, frequency increases with the increase of argon gas flow rate for one off-centered plug case. Parametric studies show that the diameter of slag eye changes from 0.43 to 0.81 in while the argon gas flow rate increases from 100 to 300 L/min for a 220 t ladle. The dimensionless areas of slag eye vs the modified Froude number is close to the experimental data in literature. Significant deformation of slag layer occurs during gas stirring operation. the thickness of slag becomes thin near the slag eye and thick near the ladle wall accordingly. The steel downward How velocity at the slag eye periphery can be affected significantly by Ar gas flow rate. The higher the velocity. the more slag could be emulsified.
