气煤性质与粒度对焦炭显微结构的影响

对2种气煤不同粒级下参与配煤炼焦后的焦炭显微结构和焦炭热性能进行分析,结果表明:气煤的性质与粒度不同时成焦发生的界面反应激烈程度不同,其结果影响焦炭热性能.气煤的粒度越小,界面接触面积越大,界面反应越激烈.气煤中活性组分含量越高,界面反应越激烈.

Effect of gas coal nature and grain size on microstructure of coke

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 compon...
