摘　　要：对陕西的一种不黏煤进行了分析,开展了捣固配煤实验。结果显示,该煤低灰、低硫、变质程度低、无黏结性,直接替代原来的弱黏煤会降低焦炭强度。通过调整配煤结构,增加配合煤胶质体数量,在捣固炼焦中配用比例达到8%,可以保证焦炭质量稳定,不仅降低了成本,还拓展了煤源。Analysis is made for a kind of non-caking coal produced from Shaanxi province.Coal blending experiment is done.The result shows that this kind of coal is characterized with low ash,low sulfur,low metamorphism(coal rank),and non-caking property,which would decrease coke strength if directly replacing the previous weakly caking coal.Coal blending composition is optimized by increasing the plastic mass in the coal blends,which takes up 8%in stamp-charge cokemaking so that stable coke quality can be ensured,with lower cost and with more coal resource to be utilized.
