1. Svobodnyi Sokol (Russian Federation). Lipetsk Metallurgical Plant

To reduce the costs of blast-furnace smelting, the Svobodnyi Sokol plant has devised a comprehensive program of organizational-technical measures that include study of ways of reducing coke consumption. To do this, the plant began operating its blast furnaces with schungite when making foundry and conversion pig irons. Using schungite in the charge employed to make foundry iron makes it possible to save a significant (10-15%) amount of coke. The value of the coefficient that characterizes the replacement of coke by schungite varies broadly and can reach 1.0 or more, depending on the grade of iron being made and the furnace operating regime. The same coefficient has a value of 0.57 kg coke/kg schungite when 12-15 kg schungite/ton pig is used to make conversion pig iron.
