冶金焦炭焦末含量及筛分组成试验的影响因素

摘要

焦末含量及筛分组成是冶金焦炭的重要指标,讨论了不同采样地点、采样方式及不同筛分方法对该指标的影响.结果表明:避免焦炭在装卸、运输及储存中产生粒度离析,采用机械筛分法或者手筛法是减少对焦末含量及筛分组成影响的有效手段.%Both coke breeze content and screen composition are important indexes of metallurgical coke. Different sampling points and different screening methods that impact the indexes were discussed. The test result showed that mechanical or manual screening was effective means in decreasing the impact of coke breeze and screen composition.
