| 摘 要： | 随着煤岩测定技术的进步，炼焦煤的煤岩性质已在炼焦配煤中得到广泛应用。通过对多种单种煤和配合煤的煤岩特征以及对应的40 kg试验焦炉所炼焦炭的性质进行分析和比较，结果表明：单煤种的R0max在1.3%～15%间，所炼制焦炭的冷态机械强度（M40和M10）最好，其热性质（反应性CRI和反应后强度CSR）也较好；配合煤反射率分布图特征越接近正态分布，则所炼制的焦炭冷态机械强度（M40、M10）就较好，配合煤反射率分布图特征偏离正态分布越远，其焦炭热性质越差；40 kg试验焦炉所得焦炭的反应性CRI高，其反应后强度CSR较低，存在负相关线形关系。

| Abstract: | With the progress in petrographic analysis of coal,petrographic analysis of coking coal is applied abroad in blending and coking.The maceral properties of single coals and blends were studied,and quality of cokes made on 40 kg pilot coke oven was analyzed.The results indicated some relations between maceral properties and quality of cokes.Firstly,cold mechanical coke strength was optimum and thermal quality was also better while mean maximun vitrinite reflectance of single coal is in the range of 1.3%-1.5%;... |
