  • Publication number: 20010029809
    Abstract: A method and composition for removing sulfur from molten ferrous material, particularly molten pig iron. The desulfurization agent includes a magnesium particle coated with a heat absorbing compound. The heat absorbing compound absorbs heat around the magnesium particle to reduce the rate the magnesium particle vaporizes in the molten iron. The particle size of the magnesium particle is at least about twice the particle size of the heat absorbing compound. A bonding agent can be used to bond the particles of the heat absorbing compound to the particle of magnesium.
