转炉一般用以下脱氧剂：Fe-Mn、Fe-Si、Mn-Si合金、Ca-Si合金、铝、Fe-Al、复合脱氧剂。脱氧剂的使用应在保证钢质量的前提下，选用价格便宜的铁合金，以降低钢的成本。
(1)用Si／Mn脱氧，形成的脱氧产物可能有：固相的纯SiO2；液相的MnO?SiO2；固溶体MnO-FeO。通过控制合适的ω〔Mn〕/ω〔Si〕比，能得到液相的MnO?SiO2产物，夹杂物易于上浮排除。(2)用S+Mn十Al脱氧，形成的脱氧产物可能有蔷薇辉石(2MnO?A1203?5Si02)；www.yejinluliao.com 硅铝榴石(3MnO?Al2O3?3SiO2)；A12O3(ω〔Al2O3〕>30％)。控制夹杂物成分在低熔点范围，为此钢中ωIAl]≤0.006％，钢中[O)溶可达0.0020％(20ppm)而无Al203沉淀，钢水可浇性好，不堵水口，铸坯不会产生皮下气孔。
(3)用过量铝脱氧。对于低碳铝镇静钢，钢中酸溶铝[Al]s含量为0.02％～0.04％，则脱氧产物全部为Al203。Al203熔点高达2050℃，在钢水中呈固态；若Al203含量多钢水的可浇性变差，易堵水口。另外，Al203为不变形夹杂物，影响钢材性能。通过吹氩搅拌加速Al203上浮排出，或者喂入Si-Ca线、 Ca线的钙处理，改变Al203性态。[Al]s含量较低，钙处理生成低熔2CaO?Al203?Si02；对于低碳铝镇静钢，通过钙处理产物易于上浮排除纯净了钢水，改善了可浇性 The?general?with the following:?Fe-Mn,?Fe-Si?deoxidizing agent,?Mn-Si?alloy,?Ca-Sialloy,?aluminum,?Fe-Al,?compound deoxidizer.
