为实现高品质低氧钢的生产，有效降低钢中全氧含量，在考虑转炉下渣、炉渣氧化性以及钢水氧活度影响的前提下，通过研究钢包渣改质技术、过程钢包渣氧化性控制技术以及相应的钢包底吹氩制度等精炼工艺，建立了转炉-连铸流程生产低氧钢的精炼工艺技术。采用该技术生产的高品质优特钢成品w(［TO］)≤15×10-6。

In order to produce low oxygen steel with high quality, converter slag-tapping, slag oxidability and oxygen activity were analyzed. In addition, modifying and adding process of slag, control of slag oxidability and bottom argon-blowing in ladle were researched as well. On this basis, refining process which is good for low oxygen steel producing with converter-continuous casting process has been developed. The results show that w(［TO］) in steel is not more than 15×10-6.
