摘　　要：优质炼焦煤资源日趋匮乏限制了高质量焦炭的生产。为此,除常规优质炼焦煤高效利用外,还需要利用弱粘结性焦煤,高硫、高灰类煤进行配煤炼焦应用,或者用非常规炼焦技术生产出满足高炉生产需求的冶金焦炭。同时,要重新衡量焦炉、焦炭与高炉之间的关系,反思高炉用冶金焦炭“冷、热”态强度质量指标评价存在的不足,明确焦炭在高炉内实际反应行为,研究高炉用冶金焦炭的匹配性评价方法,为实现“劣质”焦炭在高炉中的应用提供理论支持。The shortage of high grade coking coal resources limits the production of high quality coke.Therefore,it is necessary to utilize inferior coking coal,including weak caking coal,high sulfur or ash coal for blending coking application,or adopt unconventional coking technology to produce metallurgical coke meeting the demand of the BF production,in addition to efficiency utilization of conventional high quality coking coal.At the same time,it is necessary to reevaluate the relationship of coke oven,coke and blast furnace,reflect on the shortcomings of“cold and hot”strength quality index evaluation of metallurgical coke,clarify the actual reaction behavior of coke in blast furnace,and study the matching evaluation method of metallurgical coke,to provide theoretical support for the application of“inferior”coke in blast furnace.

关 键 词：非优质炼焦煤 冶金焦炭 劣质焦炭 焦炭质量评价 高炉
