Description
Summary:Methods of refining pig iron outside the blast furnace have become more widely used in recent years to improve pig quality. The costs of sulfur removal are significantly less here than in the blast furnace or during steelmaking. The most common methods are based on the use of metallic magnesium as the reactant-desulfurizer. Metallic magnesium is in fairly short supply and costly, so the volume of pig iron subjected to desulfurization outside the furnace and, especially, modification, is limited. The cost of the magnesium amounts to 70-80% of the total processing cost. One possible solution to the problem of expanding the raw material base for the production of reactants based on magnesium is the use of sources of secondary magnesium. The DonNIIchermet, together with the Titanium Institute, the "Krivorozhstal" plant, and the Solikamsk Magnesium Plant, has conducted commercial trials of a technology to prepare magnesium-bearing reactants using certain categories of wastes from magnesium production and has evaluated the efficiency of using these reactants to desulfurize pig iron.
