Abstract：According to the Gieseler fluidity experiment, the reliability of the weighted calculation of the Gieseler fluidity value of blending coal based on the Gieseler fluidity value of single coal was analyzed, and the variation of the Gieseler fluidity of blending coal with the blending ratio was also clarified. The results showed that the fluidity value calculated by the logarithm weighted method was in good agreement with the measured value, which could provide guidance for coal blending. And there was a clear difference of the Gieseler fluidity change rules when blending different kinds of coal. Combined with the coking experiment by 40 kg pilot coke oven, the relation between the Gieseler fluidity and coke quality was obtained.
