A new technique of bottom blown method was proposed for desulfurization of molten iron using inert gas to carry magnesium vapor combined with mechanical stirring. A water model was established based on the similarity principle. Experimental phenomena were recorded by high-speed camera, combining with image processing method, the influence factors on bubble disintegration and dispersion of molten pool were researched. By the stimulus response technique, measuring the changes of conductivity in the molten pool, influence factors of mixing time were studied. Results show that: the new technique is conducive to the bubble disintegration and dispersion of the molten pool, shorten the mixing time, prolong the residence time of the bubble in the molten pool. The desulfurization efficiency can be enhanced and the removal time of sulfur is shortened. It can also reduce the temperature drop during desulphurization and benefit to efficiency utilization of magnesium in iron industrial.
