Abstract
A process for magnesium desulfurization of ferrous metal melts in a vessel comprising the provision of a fluid, high sulfur capacity slag wherein the weight ratio of slag constituents associated with sulfur to slag constituents associated with oxygen is greater than 0.8, followed by addition of magnesium to the melt in an amount sufficient to combine with the sulfur in the melt, transfer to the sulfur removed by the magnesium addition to the slag, and retention of the removed sulfur in the slag, thereby improving magnesium desulfurization efficiency and substantially eliminating sulfur reversion from the slag back to the melt.
