Abstract
Coal quality characteristic differences and optimal blending and application technology of strong caking 1/3 coking coal whose volatile matter was in the range of 28%~32% were discussed, the fluidity and expansion had large differences when GR.I and Y values of strong caking 1/3 coking coal were similar with each other, especially the coking coal from Guizhou and Huainan provinces, whose coal quality was almost similar with metabituminous, if using them as the 1/3 coking coal, fluidity and expansion would be too high, coke quality would be reduced, if they were used as the metabituminous, rheological expansion characteristics could be fully played, the coke quality could be stabilized.Therefore, GR.I 、 Y were not reliable for distinguishing of strong caking coal, so they restricted the reasonable blending and application of strong caking coal.关键词
