METHOD OF DETERMINIG OF OPTIMAL COMPOUND OF COAL CHARGE FOR COKING Russian patent published in 2009 - IPC C10B57/04 G01N33/22 

FIELD: metallurgy.

SUBSTANCE: invention relates to manufacturing of coke, particularly preparation of coal charge for coking and can be used in chemical-recovery industry. Method includes preparation and coking of charge with different content of agglomerated, aggregated and coke components, and optimal compound of charge is defined by optimality coefficient, calculated by formula: K_opt=100(K_aK_cK_mv), %, where K_a - coefficient of correlation optimality of agglomerate and aggregate components, defined as: K_a=[100-(ΣA-43)*2]/100; K_c - coefficient of content optimality in charge coke coals, defined as: K_c=[100-(ΣC-37)]/100; K_mv - coefficient of content optimality in charge medium volatile coals, defined as: K_mv=[100-(ΣMV-23)]/100; ΣA, ΣC, ΣMV - content in charge sum of agglomerate, coke components and medium volatile coals; 43, 37, 23 - average optimal content of agglomerate, coke components and medium volatile coals.

EFFECT: it is achieved development of integral, summarise optimality indices of content of coke coal charge, providing its operative assessment and prediction of coke mechanical strength.
