转炉用单流道双流氧枪的冶金效果

Metallurgical Effact of Single Oxygen Pass Three-Hole Lance for Conventer

探讨了单流道双流氧枪在15t转炉上冶金效果。结果表明：单流道双流氧枪具有起渣早、化渣快、脱磷脱硫率高、尤其是气化脱硫率由原工艺的8．8％提高到15．13％等优点，同时还具有防返干和喷溅作用。

This paper discusses the metallurgical effect of single oxygen pass three - hole lanceon 15t converter. The resutt shows that this kind of oxygen lance has a lot of advantages, such as fastsinging and alag melting, high desulphurization and dephosphorization rates, and especially increasein gasificating desulphurization rate from 8. 8% in former process to 15. 3%. Meanwhile, it also hasfunction of splashing and avoiding being dry again.
