Crucible cokes were obtained by co-carbonization of Zhongwei lean coal as main coking coal and thermal extract from Datong long-flame coal as additive. The degree of regularization on anisotropic structure (DRAS) of coke was obtained by quantitative calculation of optical tissue from polarized microscopy. The crystallite size (L_c), aromatic condensation (L_a) and degree of graphitization (g) have been quantitative calculated by combination of XRD and curve-fitted method. Furthermore, Raman spectrum and curve-fitted method have been used to obtain content of ideal graphite microcrystalline of coke. The quantitative analysis of optical micro-component on obtained cokes shows that addition of thermal extract from Datong long-flame coal has a significant influence on optical micro-component of coke. There is good consistency on DRAS and microcrystalline parameters, which is calculated by the method of polarized microscopy and XRD and Raman spectrum, respectively. Moreover, the micro-strength index of coke is highly correlated with its microstructure.
