摘要
对蒙古国焦煤进行煤质检验及配用试验,分析了焦炭的显微结构,结果表明,蒙古国焦煤变质程度偏低(介于1/3焦煤和焦煤之间),G值、Y值和膨胀度较高,塑性温度区间窄,成焦显微结构特征类似于1/3焦煤。用蒙古国焦煤完全替代优质焦煤,焦炭质量有所下降;而采用蒙古国焦煤部分替代焦煤和1/3焦煤可以稳定焦炭质量。
The quality of coking coals from Mongolia was analyzed and blending experiments of Mongo-lia coking coals were conducted .The microstructural analysis of the produced cokes shows that the metamorphic degree of coking coals from Mongolia is low ,which is between 1/3 coking coal and co-king coal ,their G values ,Y values and dilatation are high ,their plastic temperature ranges are nar-row ,and their coking microstructural features are similar to those of 1/3 coking coal .Therefore ,if high-quality coking coal is replaced by coking coal from Mongolia ,the quality of coke produced will decrease;however ,if coking coal from Mongolia is used to partially replace coking coal and 1/3 co-king coal ,the quality of coke produced remains stable .
