烟煤为主的多煤种混合喷吹技术的实验分析

Experimental Analysis of Injection Technology of the Multicoal Mixture Composed Mainly of Bitumite

实验研究了以烟煤为主的多煤种混合煤的理化性质,包括爆炸性、燃烧性、可磨性。并讨论混合煤的性质与煤的种类和配比之间的关系及其在高炉喷吹中应用的合理性。为生产中的使用提供了重要依据。

This paper studies the physics-chemistry properties of the multicoal mixture composed mainly of bitumite including explosivity, combustion, grindability, then discusses the influences of coal's kinds and their ratios on the properties of the multicoal mixture as well as the reasonableness of application of it to blast furnace injection. This provides a basis for it's practical use.
