摘要
广钢３＃高炉富氧鼓风于１９９４年１１月３０日实施，至今已运行两年多。该富氧系统操作灵活方便，安全可靠，并取得较好的应用效果。在广钢条件下，每富氧１％，增产４．４％，节焦１．２％。同时高炉富氧后，（没有喷煤），冶炼参数发生了一系列的变化，操作上须相应进行一些调整。
The oxygen-enriched blast system at No. 3 blast furnace, Guangzhou Iron and Steel Co. has been in operation for more than 2 years since it was first put into operation on Nov. 30, 1994. The system is flexible, safe and reliable in operation, and has gained marked technical and economical effects. It is estimated, under the operation conditions at Guangzhou Iron and Steel Co., that an increase in blast oxygen by 1 percent leads to an increase in iron output by 4. 4 Percent and a decrease in coke consumption by 1. 2 Percent. However, a readjustment of the operating parameters for the oxygen-enriched blast furnace is needed to compensate for the changes in the smelting condition resulting from the oxygen addition without pulverized coal in jection.
