FIELD: metallurgy. ^ SUBSTANCE: invention relates to receiving of blast-furnace coke and can be used in metallurgy, particularly on chemical-recovery enterprises. Application of petroleum coke with high-volatile in the range not more than 14% and less than 25% in the capacity of coke addition to coal charge, used for manufacturing of blast-furnace coke. Invention provides with keeping of coke and sintering properties of addition at required level, to provide reduction of volatile matter content in charge beside the coking additions with content of volatile matter in the range from 25 up to 35%, improving, respectively, charge quality. ^ EFFECT: changing of highly rare coal of grade K for cheap coproduct - petroleum coke; petroleum coke recovery and reduction of cost of price of carbonisation process. ^ 1 tbl |
