The practice of inert gas bubbling in steel refining ladle aims the removal of non-metallic inclusions, in addition to thermal and compositional homogenization. Through physical and mathematical models of a secondary ladle refining, the effects of bubbling flow of inert gas and the number of porous plugs located at the bottom of the ladle are investigated. The velocity fields and flotation of non-metallic inclusions are analyzed by physical and mathematical modeling. The results are validated by analysis of images (PIV) and the macroscopic model is compared by industrial results for inclusions analysis for steels used in the automotive secto
