摘　　要：针对北营焦化厂原料煤应用实际,通过采用煤岩镜质组活性权函数方程,计算出加权活惰比并进行优化配煤炼焦试验,获得焦炭CSR与炼焦煤加权活惰比的关系曲线,其配合煤最优加权活惰比在2.8~3.2范围。基于此原理,在稳定配合煤指标进行的配煤炼焦试验并保证焦炭质量的前提下,可以降低焦煤和肥煤配比,加大1/3焦煤和瘦煤比例,从而降低配煤成本。结果表明,炼焦煤加权活惰比与焦炭的CSR具有密切相关关系,相关系数R为0.919。经过生产焦炉进一步验证试验,在强黏结性煤降低8%的情况下,焦炭质量尚有提升。According to the situation of coal using in Beiying coking plant,the weighted active inert ratio is calculated through the vitrinite active weight function equation,and the optimized coal blending and coking experiment is carried out.Then the relation curve between coke CSR and coking coal weighted active inert ratio is obtained.The best weighted active inert ratio of blended coal is in the range of 2.8~3.2.Based on this principle,on the premise of coal blending and coking experiment and ensuring coke quality,the ratio of coking coal and fat coal can be reduced,and that of 1/3 coking coal and lean coal is increased,so as to lower the coal blending cost.The result shows that the weighted active inert ratio of coal is closely related to the CSR of coke,and the correlation coefficient is R=0.919.From the experience of coke oven production,coke quality can be improved when strong caking coal is reduced by 8%.
