The lime fuses with the impurities to form slag, which separates from the steel and is removed. This process improves the quality of the steel. Lime is also used to enhance the refractory life of the furnaces. The magnesium oxide (MgO) in dolomitic lime reduces the tendency of steel slag to dissolve the MgO within the furnace refractory.
