本文阐述在１８ｔ钢包中吹Ａｒ喂Ａｌ线处理钢水的试验情况，并着重对在线工艺和喂线效果进行了分析。试验结果表明：钢中酸溶铝含量稳定，铝的收得率提高；改善了脱氧，强化了脱硫；钢材力性提高，高低倍得到改善。
This paper describes the experiment of blowing Ar-fed Al wire in 18t ladle to treat molten steel, and focuses on the on-line process and feeding effect. The test results show that the content of acid-soluble aluminum in steel is stable, the yield of aluminum is increased, the deoxidation is enhanced, the desulfurization is enhanced, the strength of steel is improved, and the height and height are improved.
