摘　　要：文章对包钢捣固炼焦配合煤不同粒级煤的性质进行了分析,根据不同粒度组成配合煤的质量指标,优化了配合煤粒度分布,逐渐降低了配合煤粒度组成的标准方差。通过开展选择性预粉碎工艺,将硬煤进行选择性粉碎,稳定了配合煤质量。在保证煤饼稳定性前提下,提高了1/3焦煤和气煤配比,节约了优质炼焦煤用量,降低了配煤成本。In the paper,the particle size distribution of blended coal is optimized according to the quality indexes of blended coal with different granularity compositions through analyzing properties of blended coal for tamping coking of Baotou Steel with different particle sizes so that standard deviation of granularity composition for blended coal gradually reduces.In addition,the selective comminution of hard coal is carried out through selective precomminution technology so that the quality of blended coal is stabilized.On the premise of ensuring stability of coal cake,1/3 proportion of coking coal and gas coal is improved so that the consumption of high-quality coking coal and cost of blending coal reduce.
