提高富氧率技术攻关实践

Practice of Increasing the Rate of Oxygen Enrichment Technology

通过韶钢1 050 m3高炉富氧率由1. 8!提高至3. 5!的攻关实践,总结出高炉提高富氧率后炉况及高炉指标的变化特点以及高炉操作制度的变化规律.高炉强化冶炼后对原料质量指标有更高要求.攻关实践为1 050 m3级高炉实施大富氧技术提供了技术支撑.

Based on the application of 1 050 m^3 after the oxygen enrichment rate for BF was increased from 1.8 %to 3.5 % for the research and practice, furnace conditions and the change characteristics of blast furnace indice, operation system, raw materials＇ demand for higher quality indice were summarized which provided the technical support.
