FIELD: coal-tar chemical industry, namely charge compositions for producing metallurgical coke. ^ SUBSTANCE: first composition of charge contains 25 - 65% of medium-volatile or gas medium-volatile coals and 35 - 75% of low caking coals. Second composition of charge contains 25 - 65% of medium-volatile or gas medium-volatile coals and 35 - 75% of lean coals. Third composition of charge contains 25 - 40% of medium-volatile coals, 35 - 60% of low caking coals and 5 - 35% of gas medium-volatile coals. Fourth composition of charge contains 30 -55% of gas medium -volatile coals, 30 - 60% of low caking coals and 5 - 20% of lean coals. Fifth composition of charge contains 35 - 40% of medium-volatile coals, 5 - 15% of gas medium-volatile coals and 50 - 55% of low caking coals. Sixth composition of charge contains 10 - 30% of medium-volatile coals, 20 - 30% of gas medium-volatile coals, 20 - 60% of low caking coals and 5 - 25% of lean coals. ^ EFFECT: possibility for producing high-quality metallurgical coke of offered compositions of charge. ^ 6 cl, 22 ex, 1 tbl |
