Abstract:

The 1/3 coking coals from Henan and Shandong are analyzed and compared.The result shows that blending of Henan A mine is good for the fluidity and dilatation,and the coarse mosaic texture is much more than Shandong B mine.The coking microstructure of single coal of 1/3 coking coal in B mineral is mainly fine mosaic structure.Higher blending ratio of it will worsen the coke quality.For the coking coal with similar caking index and maximum thickness of plastic layer,that with better fluidity and dilatation properties is good for the improvement of coke quality.
