摘要
本文介绍了龙钢高炉富氧喷吹煤粉的设计技术特点。实践证明,通过狠抓入炉原燃料质量、改善高炉透气性、优化高炉操作制度、狠抓炉前管理等措施,取得了较好的经济效益,其中1#高炉富氧率已接近3%,利用系数达到3.12,煤比达112 kg/t。
The present paper introduces the design and technological features of coal injection enriched with oxygen in Long-Men Iron ＆ Steel co,Ltd. By means of strictly controlling raw material and fuel quality, improving air permeability of burden, optimizing operation system of blast furnace, increasing blast air temperature and strengthening management of cast house, the oxygen enrichment ratio of blast furnace comes to about 3%, the productivity to 3.12 and the coal ration to 112 kg/t.
