煤岩学在炼焦生产中的应用

 为了改善焦炭质量，降低配煤成本，鞍钢鲅鱼圈利用测定煤显微结构的镜质组反射率，并将其绘制成分布图的煤岩学方法监控来煤质量，建立了本企业的煤岩配煤方法，开展煤岩配煤的应用研究，有效地杜绝了复杂混煤入厂，优化了配煤结构，提高了焦炭质量。结果表明，应用该技术后鲅鱼圈焦炭的冷态性能M40、M10、热态性能CRI、CSR提高明显，分别从2011年的88.11%、6.75%、27.36%、62.20%，逐步改善到2014年的88.88%、6.26%、23.89%、66.26%，主焦煤配比从2011年的75%下降到目前的69%。

Application of coal petrography analysis on coking production

In order to improve the quality of coke and reduce the cost of coal blending at the Bayuquan Iron and Steel Subsidiary Company of Angang Steel Co.， Ltd.， the quality of coal was analyzed for coal petrology microscope， the method of coal blending was built and the application of Coal Petrograph was researched on coking production， aiming to avoid the adulteration of complicated mixing coal， optimize the method of coal blending and improve the quality of coke. The structure of coking coal and quality of coke were optimized. The results showed that after the application， the cold and hot performances of coke， M40 ， M10 ， CRI and CSR increase from 88.11%， 6.75%， 27.36%， and 62.20% up to 88.88%， 6.26%， 23.89% and 66.26%， respectively. The blending ratio of prime coking coal falls from 75% falling to 69%.
