Formed coke production from coals from various coalfields
Development work on formed coke production has for some years been at the forefront of research, development, and experimental design efforts on new ways of making metallurgical fuel, both here and in other countries. Interest has been aroused by a number of factors, including the gradual deterioration in the coal supply situation or the exhaustion of coals suitable for the conventional coking process, the need to improve the mechanical strength and size analysis of blast-furnace coke arising from the use of higher driving rates and larger furnaces, the need to protect the environment from pollution, and to make the coking process fully mechanized and automated, and the various social aspects (improved working conditions in pits and coke-oven plants). The Soviet process for making formed metallurgical coke from gas and poorly-caking coals satisfies all these requirements to the full. Blast-furnace trials in 1972 with 100 percent formed-coke burdens demonstrated that the new fuel has outstanding metallurgical properties and will promote a substantial increase in blast-furnace driving rates. Success in the Soviet Union has provoked interest from many foreign concerns, and in 1975 laboratory trials were carried out at UKhIN on the production of formed coke by the Soviet process from two coals representing American supplies and six representing Japanese. Laboratory test data are presented, showing that formed coke can be made from foreign coals. The Soviet process can produce high-quality formed metallurgical coke from a wide range of foreign coals and blends.
