| 摘 要： | 基于邯钢高炉喷煤现场，对其所用无烟煤及拟用烟煤进行了工业分析、喷流特性、爆炸性、着火点、灰熔点以及配煤燃烧率系统研究。结果表明，大湾煤是邯钢高炉喷吹烟煤的首选煤种，其次是准联煤和老张沟煤；长治煤是邯钢高炉喷吹无烟煤的最佳煤种。大湾烟煤与长治无烟煤组成的混煤为较好的选择。 |

| Abstract: | Based on the coal injection state of Hangang blast furnace, the physical and chemical analyses of anthracite coal and bituminite, such as industry analysis, jet characteristic, explosiveness, flare point, ash fusion point and mix coal burning rate, were researched systemically. The results show that Dawan coal is the best kind of bituminite to be used in Hangang blast furnaces, Zhunlian and Laozhanggou bituminite are the next choices. The optimal anthracite coal is the Changzhi anthracite. The compose of Dawan coal and Changzhi coal is the better mixed coal to be used in Hangang blast furnace. |
