The research institutes have developed and introduced various methods to maintain the current coke quality levels, including new processes capable of exploiting poorly- and non-caking coal supplies. The tighter quality specifications on metallurgical coke as a blast-furnace processing fuel will be reflected in otpimum coke lump sizes, greater size uniformity, higher strength, lower reactivity, and lower ash and sulfur contents. In this connection, a complex research program must be carried out to improve plant processing standards with reference to charge preparation, carbonization, quenching and grading. The coke production process will be improved by increasing unit coke-oven battery capacities, intensifying the carbonization process, introducing dry coke cooling and thermal charge preparation and so on. In the future, batteries will only be constructed with coke-oven volumes of 41.6 m/sup 3/ or more. The construction of high-productivity batteries to replace the existing batteries will greatly increase the labor productivity indices and reduce air pollution. In order to perfect the formed metallurgical coke production process and exploit this process more widely, further work is required on the cleaning of spent heat carriers and equipment purging products; economic methods must be devised to utilize the coal tar, fly ash and acid sludge, to improve the yield and quality of chemical products, etc.
