    Metallurgical coke is widely used in various industries in Japan In a coke furnace, coal is heated indirectly (for 14 to 18 hours at 1,200 to 1,300°C) and then carbonized (dried by distillation) for about 24 hours Subsequently, it is fractionated into coke and other materials, such as gases, tar oil, benzene, toluene, and naphthaleneHigh volatile matter reduces the yield of metallurgical coke in Coke Oven Battery but improves the coke oven gas generation Low VM coals have high pressure on the cokeMetallurgical Coal Steel360Both models depend on metallurgical coke grinding conditions and are hence an indication of the grinding behaviour Finally, oversize and ultrafine particles are found with ball sizes of 40 cmArrangement of fibrils, microfilbris, and cellulose in
