FIELD: chemistry.
SUBSTANCE: invention relates to coke-chemical industry, namely to composition of charge for production of metallurgical coke. Charge includes: mixture of coal of sintering groups: G (gas), and/or GF (gas fat), and/or GFL (gas fat lean), and/or F (fat) and lean groups: LCC (low-caking coke) and/or LC (lean caking) in weight ratio of 1:1.15 in amount of 60–93.5 wt. % and petroleum coke obtained by delayed coking of heavy oil residues, with a sintering capacity of 75–100 units (GOST ISO 15585-2013) in amount of 6.5–40.0 wt. %.
EFFECT: development of charge for coking of special composition, which allows to expand and reduce the cost of raw material base of used charge with improvement of quality of metallurgical coke with improved strength characteristics.
