Abstract: The efficiency of the use of desulfurizing agents, particularly calcium carbide- and calcium oxide-based desulfurizing agents, to decrease the sulfur content of molten iron is improved by adding a pulse of magnesium, aluminum or calcium metal at a critical concentration of sulfur and oxygen in the molten metal. The improved efficiency enables less desulfurization agent to be employed for the same residual sulfur concentration, with consequently decreased reaction time and costs.

Abstract: A reagent for desulfurizing molten iron comprising calcium carbide and/or lime and an asphaltite. The reagent may contain, in addition, magnesium which is either uniformly distributed within the reagent mixture, or stored separately and added to the mixture during fluidized transport of the reagent just prior to injection to vary the addition of magnesium for any given injection.
