Theoretical and experimental foundations for preparing coke for blast-furnace smelting

This article examines the preparation of coke for blast-furnace smelting by a method that most fully meets the requirements of blast-furnace technology: screening of the -36 mm fraction, the separation of nut coke of the 15-36 mm fraction, and its charging into the furnace in a mixture with the iron-ore-bearing charge components. An analysis is made of trial use of coke of the Premium class on blast furnace No. 5 at the Enakievo Metallurgical Plant. Use of this coke makes it possible to reduce the consumption of skip coke by 3.2-4.1%.
