对9种不同变质程度的炼焦煤进行固体三维扫描荧光光谱测定,分析了荧光特性参数(Q 1/2值)、黏结指数(G 值)和最大流动度(lgα)之间的关系。研究结果表明, Q 1/2值、G 值和 lgα等黏结性指标具有线性关系,Q 1/2值越大黏结性越好。对于强黏结性的炼焦煤来说,Q 1/2值线性增加幅度越大,特征荧光参数 Q 1/2值可作为一个新的指标表征炼焦煤的黏结性。

The authors measured three-dimensional scanning fluorescence spectra of nine co-king coal with different metamorphic grades,and analyzed the relationships between the fluores-cence characteristics parameter (Q 1/2 )and caking index (G )and maximum fluidity (lgα). The results showed a linear relationship between Q 1/2 and G ,lgα of the coking coal:the bigger of the value of Q 1/2 ,the stronger caking properties of the coking coal;for the high binding property co-king coal,when the liner value of Q 1/2 increased sharply,the fluorescence characteristics parame-ter (Q 1/2 )became a new index to represented the caking properties of coking coal.
