ABSTRACT:
A method of production of blast furnace coke comprising drying mixed coal, then, or simultaneously with the drying, classifying it to fine-grained coal and coarse-grained coal, then adding to the fine-grained coal at a temperature of 80 to 350° C. a caking additive comprised of one or more of a heavy distillate of tar, soft pitch, and petroleum pitch, agglomerating it by hot pressing, then mixing the clumps of coal and the coarse-grained coal and charging and carbonizing the mixture in a coke oven.
