Abstract:

The microstructures and hot property of the coke made with two types of gas coal with different grain sizes used in coal blending are analyzed. The result shows that when the gas coal nature and grain size are different, the degrees of reaction impetuosity occurring on the interface of the coke made are different, its result influences coke property. The smaller the grain sizes of gas coal, the bigger the interface contact area and the more impetuous, the interface reaction. The higher the content of active component in gas coal, the more impetuous, the interface reaction.
