PROCEDURE FOR PREPARING COAL CHARGE FOR PRODUCTION OF METALLURGICAL COKE Russian patent published in 2010 - IPC C10B57/04 G01N33/22 

FIELD: metallurgy.

SUBSTANCE: there is performed laboratory coking. Quality of each i-coal component used for preparation of charge for coking is evaluated relative to coefficient of process value (CPV_i). Share of each i-coal component used at preparation of charge is determined in a coke and caking groups and by their dimension with consideration to coefficient of process value of each i-coal component. Coefficient of process value is determined correspondingly of the coke group (CPV_k) and of the caking group (CPV_c) and for coal charge (CPV_ch). Further there are determined shares of coke and caking groups in coal charge for production of metallurgical coke (C_cch, C_cakech). Share of each i-coal component contained correspondingly in coke and caking groups in charge for production of metallurgical coke is determined on base of value of share of each i-coal component used for preparation of coal charge correspondingly in the coke and caking groups and on base of shares of the coke and caking groups in coal charge for preparation of metallurgical coke.

EFFECT: preparing coal charge including coal components of various grades and wide range of coal basins for production of metallurgical coke of high mechanical properties.
