ABSTRACT:
A method of manufacturing blast furnace coke wherein said coke is obtained by a process in which coal to be used for making briquettes is mixed with a caking substance having a softening point of 40.degree.-250.degree. C. with or without a solvent having fluidity at the mixing temperature and dissolvable to said caking substance, the resultant mixture being mixed by means of a powerful mixer capable of applying mixing energy of 0.01KW/Kg or more at a temperature of 40.degree.-250.degree. C. for 1-10 minutes, while a heating medium such as steam is passed therethrough and is then subjected to briquetting with a roll press. The briquette obtained is either carbonized directly or after blending with coal ready for coke oven charging.
