摘要
本文研究了两种硅－铝－钡－钙脱氧剂的应用效果，发现它们有良好的脱氧和控制钢中非金属夹杂物的作用，使用方便、安全，并使吨钢成本有所下降．钡、钙作用互补，但其中的含钙且也不必过高．
The authors have studied the deoxy effections of two kinds of Si-Al-Ba-Ca ferroalloy deoxidants and found;that both deoxidants have good effect on deoxidizing and modifying nonmetallic inclusions in steels and are convenient and safe in employed processand decrease in cost of steels in some extent;that the effects of barium and calcium are supplemental each other,it isn't necessary that the deoxidants contain more calciumover some suitable quantity.
