PCT No. PCT/JP96/00226 Sec. 371 Date Jan. 13, 1997 Sec. 102(e) Date Jan. 13, 1997 PCT Filed Feb. 2, 1996 PCT Pub. No. WO96/23852 PCT Pub. Date Aug. 8, 1996A blast furnace coal is produced by rapidly heating a coal blend having 10 to 30% by weight of a non-slightly-caking coal having softening initiation temperature T with the balance including a caking coal having softening initiation temperature T0 (T0</=T +40 DEG C.) at a rate of 1x103 to 1x106 DEG C./min to a temperature region from (T -60 DEG C.) to (T +10 DEG C.) wherein T represents the softening initiation temperature of the non-slightly-caking coal; or rapidly heating a non-slightly-caking coal having softening initiation temperature T and a caking coal having softening initiation temperature T1 separately at a rate of 1x103 to 1x106 DEG C./min to a temperature region from (T -100 DEG C.) to (T +10 DEG C.), wherein T represents the softening initiation temperature of the non-slightly-caking coal, or a temperature region from (T1-100 DEG C.) to (T1+10 DEG C.), wherein T1 represents the softening initiation temperature of the caking coal, blending the heated non-slightly-caking coal with the heated caking coal to prepare a coal blend having 10 to 30% by weight of the non-slightly-caking coal with the balance including the caking coal; and charging the coal blend into a coke oven where the coal blend is carbonized.
