The intensification of blast-furnace operation and the increase in blast-furnace size have necessitated production of coke with improved physicomechanical properties. It follows from analysis of current coke-quality requirements that metallurgical coke must have adequate abrasion resistance and be uniform in size, containing minimum amounts of lumps more than 60 and less than 25 mm in size. These requirements have increased the importance of the techniques used to prepare blends for carbonization. The quality of blast-furnace coke depends in large measure on the physicochemical properties of the coal charge and the thermotechnical conditions of its carbonization. Charge physicochemical properties are governed by the properties of the coal, including moisture content, size-class distribution, rank, granulometric composition, and bulk density. These properties can be regulated by modifying the preparation technology.
