COKES AND MANUFACTURING METHOD FOR COKES

摘要

The present invention relates to cokes and a manufacturing method of cokes. The manufacturing method of cokes comprises the processes of: preparing a catalyst containing coking coal and iron (Fe); manufacturing a mixture by mixing the coking coal and the catalyst; manufacturing cokes by charging the mixture into a coke oven, and carbonizing the same; extruding the cokes from the coke oven, and then charging the same into a chamber; combusting the cokes by supplying gas containing oxygen to the chamber; and cooling the cokes. Therefore, the method can inhibit a corrosion phenomenon of a refractory material in the coke oven and environmental pollution by decreasing a ratio of a reductant in a blast furnace operation.
