选取23个单种煤进行了焦炭性能的影响因素研究，在20 kg试验焦炉中进行炼焦试验，并进行焦炭质量分析试验。通过23个单种煤焦炭的X射线衍射图，计算焦炭微晶结构参数，研究焦炭微晶结构特性与焦炭宏观性能关系。结果表明：焦炭气孔壁最基本单元——微晶结构是影响焦炭宏观性能的最本质因素。焦炭微晶结构与炼焦煤的煤化度关系密切，致密度和单元大小在煤岩镜质组反射率Rr为1.2%左右达到最大值。

In order to study the influencing factors on coke property, 23 single coals were used for coking test proceeded in 20 kg coking battery and coke quality analysis. The crystallite structure parameters of obtained cokes were calculated by XRD. The relationship between crystallite structure of coke and coke macroscopic property was studied. The results show that the basic influencing factor on coke property is the structure of crystallite, as the basic unit of pore wall of coke. The crystallite structure of coke has a close relationship with the coal rank of coking coal. The density and unit size of crystallite are up to a maximum at coal vitrinite reflectance Rr about 1.2%.
