The Novolipetsk Metallurgical Combine developed a technology for producing iron-bearing lime by the combined calcining of limestone and converter slag in kilns. The resulting flux was a lumpy two-layer product with a core consisting of high reactivity lime and a surrounding shell of calcium ferrites. Compared to conventional lime, iron-bearing lime has smaller losses during calcining and contains less sulfur and more iron oxides. The cooling effect was 8.2% less than for normal lime. Replacing conventional lime with iron-bearing lime also makes it possible to reduce the amount of sulfur contributed to the bath by the fluxing materials and to increase the output of usable metal.
