摘　　要：本文运用焦炭的显微结构特征,对气煤的结焦过程行为进行探索。通过对比不同粒度条件下气煤的结焦结构变化,对气煤在结焦过程中胶质体的变化情况进行分析。结果显示气煤的胶质体在结焦过程中呈现出较好的铺展性,但是胶质体的质量不高,因此导致气煤的粘结能力较弱,对气煤的粒度进行控制能降低气煤参与配煤带来的部分问题,但是对其他煤种的胶质的影响需要进一步的试验研究。In this paper,the microstructure characteristics of coke has been used,to explore the behavior of the coal coking process. Through the comparison of different particle size of coal coking structure changes,and analyzed the change of coal in the coking process of plastic mass. Results showed that the coal of colloid in the coking process shows good spreadability,but the colloid quality is not high,thus leading to coal bonding ability is weak,of coal particle size control can reduce the coal in coal blending part,but effects on other coal glial need further experimental research.
