Recent years, a manufacturing of high-strength coke for stable low RAR blast furnace operation is required to reduce CO, emission. On the other hand, resource depletion of high-quality coal and iron ore continues. Thus it has become much more important to produce high quality burden using low grade resource. As for coal, in conjunction with the ris- ing price of high-quality caking coals, it is difficult to obtain non or slightly caking coals. So utilization of carbon resources for cokemaking is an important issue.
