摘　　要：在韶钢高炉喷煤制粉系统的改造中,采用了高浓度煤粉袋式收集器、高效粗粉分离器、煤粉分配器等新技术,改变了传统的多级收粉方式和复杂的输粉工艺.介绍该系统改造前存在的问题,以及改造的内容和改造后的运行效果.New techniques using bag collector for high-concentration pulverized coal, high-efficiency separator for coarse pulverized coal, and pulverized coal distributor are employed in modifying the coal grinding system associated with the pulverized coal injection for the blast furnaces at Shaoguan Iron & Steel Group Co. , Ltd. , which have brought about a remarkable change in both the conventional multi-stage collecting mode and the complicated pulverized coal transport process. The problems encountered before the modification, the details of the modification, and the benefits brought in by the modification are all described in the present article.
