Abstract
In order to clarify the mechanism of interfacial distribution and determine the balance of sulfur, the data from the full-scale experiments of magnesium desulfurization were used. While making up the sulfur balance, in addition to elements transfer from metal into the slag, the impact of the following factors was taken into the account – the change of molten metal mass in the ladle due to the iron oxidation and generation of the metal droplets in the slag, as well as the increase of dissolved sulfur in the iron droplets. The calculated results were compared to various experimental data of the quantity of sulfur loss by upward streams. The dependence of sulfur loss degree from the slag amount and technological parameters of magnesium desulfurization of molten metal were determined.
