摘　　要：选用焦煤、1/3焦煤、肥煤、瘦煤、长焰煤进行配煤,堆密度为0.7g/cm3和1.0g/cm3,采用2kg焦炉炼焦,对焦炭的冷态强度和热态性能分析检测,探讨了堆密度及低阶煤加入量对焦炭性能的影响,结果表明,配入低阶煤后,焦炭的冷态强度及热态性能变差,配比小于5%时,影响较小,适当提高原料煤堆密度,焦炭的冷态强度及热态性能得到改善。This paper described coal blending with coking coal, 1/3 coking coal, fat coal, lean coal and long-flame coal,with bulk density of 0.7g/cm3 and 1.0g/cm3 and analyzed the impact to coke behavior under different bulk densities and different adding amount of low rank coal by using 2kg tes- ting coke oven for analysis of cold strength and thermal property of coke. The results show that the cold strength and thermal performance of coke get worse after blended with low-rank coal, and it changes less when blended with low-rank coal less than 5% ,but it can be improved by increasing the bulk density of blended coal.
