FIELD: metallurgy.
SUBSTANCE: method includes preparation of compositions of two-component mixtures of two kinds: compositions from two well-coking coal with high degree of caking, in preference rich coal, from it there are received rich compositions, and compositions from two medium-coking coal with low degree of caking, in preference leaned coal, from which there are received leaning compositions. From rich compositions the first composition consists of 3-97 wt % rich coal and 3-97 wt % fiery coal. The second composition consists of 3-97 wt % fiery coal and 3-97 wt % fiery rich coal. The third composition consists of 3-97 wt % fiery rich coal and 3-97 wt % fiery coal. The fourth composition consists of 3-97 wt % fiery rich leaned coal and 3-97 wt % fiery rich coal or fiery coal. The fifth composition consists of 3-97 wt % fiery rich leaned coal and 3-97 wt % fiery coal. The sixth composition consists of 3-97 wt % coke rich coal and 3-97 wt % fiery rich coal. From leaned compositions the first composition consists of 3-97 wt % each of coal; coke and coke leaned. The second composition consists of 3-97 wt % each of coal: coke and coke low-caking or coke low-caking low-metamorphised. The third composition consists of 3-97 wt % each of coal: coke leaned and coke low-caking or coke low-caking low-metamorphised. The fourth composition consists of 3-97 wt % each of coal: leaned caking and coke low-caking or coke low-caking low-metamorphised. The fifth composition consists of 3-97 wt % each of coal: leaned leaned and coke low-caking or coke low-caking low-metamorphised. The sixth composition consists of 3-97 wt % each of coal: low-caking and coke leaned or coke low-caking. The seventh composition consists of 3-97 wt % each of coal: coke coals and leaned caking or leaned caking, or low-caking.
EFFECT: simplification of charge preparation technology for receiving of high-quality coke grade.
