FIELD: metallurgy.
SUBSTANCE: invention relates to the coke chemistry and metallurgy, and can be used during the high-quality coke production from the non-caking or low-caking coals. Non-caking or low-caking coal is evaluated as suitable as the raw material for coke production, if it does not significantly reduces the coke strength and has a maximum Gieseler fluidity MF more, than the coal maximum Gieseler fluidity MF, in which no primary or secondary amines are added, including the aromatic cycle, which is N,N'-di-2-naphthyl-p-phenylenediamine, at that, before the amine addition to coal the non-caking or low-caking coal has a maximum Gieseler fluidity MF of 20 ddpm or less. Then performing the coals mixture carbonization, including coal, estimated as applicable for the coke production.
EFFECT: invention allows to accurately determine the non-caking or low-caking coals suitability as raw material for the coke production.
