武钢高炉喷吹用煤粉特性研究

武钢地处内陆，运输距离长，缺少高炉喷吹用煤资源，多年来，武钢高炉炼铁工作者针对各种煤粉就成分、可磨性、灰熔点、发热值、着火点、爆炸性、燃烧性等特性进行了系统的研究，在此基础上选定了武钢高炉喷吹用煤的种类，使用后取得了较好的生产指标，实践证明，上述指标对于选择合适的煤种具有重要价值。

Study of the characteristics of pulverized coal injection in WISCO

Wuhan Iron and Steel Corp. （WISCO） is located in the center of China, and it is short of the pulverized coal. In order to choose the suitable pulverized coal, these years some characteristics of coal, such as compositions, grindability, ash melting point, calorific value, fire point, explosibility and combustion properties, had been investigated by some researchers in WISCO, so the types of coal used as pulverized coal were decided according to the values of test, and good results were achieved by using such coals. It was proved that these characteristics of coals had important value to choose suitable pulverized coal.
