摘　　要：本文详细介绍了太原钢铁(集团)公司18吨AOD炉顶侧吹工艺试验,其工艺方法是增加顶侧吹氧以使炉气中的CO二次燃烧为CO_2,燃烧热通过激烈搅拌的熔池传递给钢液,从而改善热平衡,达到提高脱碳速度,缩短冶炼时间的目的。This paper described a 18t AOD top-side blowing test at Taiyuan Iron & Steel Co. It's process method is to enhance the oxygen via top-side blowing of vessel to burn CO into CO2 above bath surface, and the heat generated there is directly transferred to liquid steel via the bath being stirred vigorously for the improvements of heat balance, and increasing of decarburization rate and reducation of refining time.
