Abstract:

In view of the unpredictability for the caking properties of blended coal,a bottleneck in coking industry,due to mixing with low caking coal,thus comparison is made for the impacts to the blended coal caking properties between two scenarios,i.e.blending with two kinds of low caking coals (5%~25%) individually and blending with them both.The result shows that for most of caking properties of the blended coal,there will be a clear linear dependence between the values predicated and measured when blended with the said two kinds of low caking coals.It is found that the value b can also be accurately predicted by the equation in this paper.
