摘　　要：利用煤岩学对新疆不同变质程度煤进行了相变机理的研究,探讨了焦炭显微结构对焦炭热性能的影响。 当焦炭粗粒、片状组分增加,同性组分减少时,焦炭的应性低,反应后强度提高;当焦炭纤维结构增加,粗粒、 片状组分减少时,焦炭的反应性增加,反应后强度下降。Phase transition mechanism of Xingjiang coal with different coalification is studied by means of coal petrology, the influence of coke micro - structure on coke thermal property is discussed. When coke coarse and flaky components are increased and component with the same nature is reduced, coke reactivity is lower, coke strength after reaction is increased; when coke fiber structure is increased and coke coarse and flaky components are reduced, coke reactivity is increased, coke strength after reaction is reduced.

关 键 词：显微结构 半镜质组分 焦炭热性能
