An Investigation into Coal Blending and the Addition of Semi-coke
-
摘要: 为了确定合适的配煤喷吹方案,对高炉喷吹用煤和兰炭的可磨性、爆炸性和着火点等性能进行了测试分析,探讨了配煤对煤性能的影响。研究结果表明:配煤后煤的可磨性增加,爆炸性减弱,着火点降低,因此采用无烟煤、烟煤和兰炭搭配组成的混合煤可以获得更优良的冶金性能。Abstract: The grindability,explosibility and ignition point of coal and semi-coke to be injected into blast furnace has been tested to determine the appropriate blending scheme,and the effect of coal blending on coal properties has also been discussed.The results show that through coal blending,the grindability of coal is increased while the explosibility and ignition point of coal are lowered,so the mixture consisting of anthracite,bituminous coal and semi-coke can exhibit better metallurgical properties.
