The invention relates to coke chemical production, and more specifically it relates to compositions for producing metallurgical coke. A charge for obtaining metallurgical coke, with an optimized proportion of components of regular coals of various ranks, containing:
(25 - 65) % b.w. fat or gas fat coals and (35 - 75) % b.w. low-coking caking coals; or
(25 - 65) % b.w. fat or gas fat coals and (35 - 75) % b.w. weak coking coals; or
(25 - 40) % b.w. fat coals, (35 - 60) % b.w. low-coking caking coals and (5 - 35)% b.w. weak coking coals; or
(30 - 55) % b.w. gas fat coals, (30 - 60) % b.w. low-coking caking coals and (5 - 20)% b.w. weak coking coals; or
(35 - 40) % b.w. fat coals, (5 - 15) % b.w. gas fat coals and (50 - 55)% b.w. low-coking caking coals; or
(10 - 30) % b.w. fat coals, (20 - 30) % b.w. gas fat coals, (20 - 60)% b.w. low-coking caking coals and (5 - 25) % b.w. weak coking coals. |
