The Donetsk Metallurgical Plant has been replacing some of the coke with pulverized-coal fuel in the production of conversion pig iron. Recent modifications of the blast furnace now make it possible to produce foundry iron as well. The unit which injects and prepares pulverized-coal fuel includes a section for preparing the coal dust, two distributing-batching sections, two independently operating fuel-preparation lines, an iron notch and slag notch and 12 tuyeres. Sinter was the primary component in making foundry iron. These changes were found to increase the combustion temperature, reduce the slag melting point when hot grades of iron were produced, reduce coke consumption, and reduce carbon monoxide emission and the temperature of the top gases.
