Abstract

PURPOSE: To obtain a metallurgical coke having a high coking strengty with a small amount of bituminous substances, by carbonizing a blend of a small amount of bituminous substances with a powdered charging coal having a narrowed particle size distribution.
CONSTITUTION: A coal is powdered in the powdering step with a sieve to give a powdered uniform coal comprising the active ingredient having a minimum specific surface area with a narrowed particle size distribution. The powdered coal is then blended with not less than one wt.% and less than 30 wt.% of bituminous substances, and the resulting blend is carbonized to produce a metallurgical coke. The particles of the active ingredient can be covered with a small amount of the bituminous substances before softening and melting of the coal, thus giving the coke with a high coking strength.
