摘要：

对焦炭显微结构与热性质的关系进行了研究，分析了不同CRI和CSR指标工业焦炭的气孔结构和光学组织结构的特征。采用连续热失重法对焦炭进行了1 100 ℃的恒定溶损失重测试，并检测了焦炭溶损失重25%后的强度指标CSR25%。通过多元回归建立了焦炭热性质指标与显微结构参数的关系，结果发现气孔壁平均厚度与CSR25%的相关性最为密切，该结论可为精细化配煤、优化焦炭结构和性能提供重要支撑。

Abstract:

In this paper,the relationship between the microstructure and thermal properties of coke was studied,and the characteristics of stomatal structure and optical structure of industrial coke with different CRI and CSR indexes were analyzed.The fixed solution loss test at 1，100 °C was carried out by continuous thermal weight loss method,and the strength index CSR25% after the coke solution loss at 25%.The relationship between coke thermal properties and microstructural parameters was established by multiple linear regression.It was found that the average thickness of the pore walls was most closely related to the CSR25%.The conclusion provides important support for refined coal blending,optimizing coke structure and performance.
