Abstract:
A process for making a blast furnace coke, comprising the steps of:rapidly heating a coal blend comprising10 to 30% by weight of a non- to slightly-caking coal characterized by a softening initiation temperature of T.sub.1 ; andthe balance consisting of a caking coal characterized by a softening initiation temperature of T.sub.0, where T.sub.0 .ltoreq.T.sub.1 +40.degree. C.; whereinsaid heating is at a rate of 1.times.10.sup.3 to 1.times.10.sup.6 .degree. C./min to a temperature region from T.sub.1 -60.degree. C.) to (T.sub.1 +10.degree. C.); andcharging the heated coal blend into a coke oven where the coal blend is carbonized.
