The effect of finishing temperature and soaking of the coke in the oven upon the microstructure and strength of metallurgical coke

Large modem blast furnaces, such as No. 5 unit at Port Kembla vihlch produces 7,000 tonnes per day of iron, demand high quality feed materials. The blending of coals to yield coke of the required cold strength \^?as resolved by the mid seventies and in the last decade iiifumace properties have been studied critically. Japanese technologists have claimed iitprovement by the practice of soaking the coke in the ovens at the finishing carbonization temperature.
