摘要:

研究了半焦粉粒度对型煤密度和型焦强度的影响,结果表明随着半焦粉粒度降低,型焦强度先升高后降低,在半焦粉粒度<3mm时达到峰值,采用最佳粒级配比后,所得型焦强度明显提高。

Abstract:

The influence of semi-coke grain size on density of briquetted coal and strength of briquetted coke is studied.It is found that,as the grain size of semi-coke breeze decreases,the strength of briquetted coke increases,and then declines after reaching the peak where the grain size of semi-coke is below 3mm.The strength of briquetted coke produced can be increased significantly when the best blending ratio is adopted.
