对钢包渣与锰钢的反应进行了室内试验研究。结果表明，当渣的碱度[R=w(CaO)/w(SiO2)]足够低时，如R< 4，铝淬钢中溶解的铝可以降低渣中SiO2的含量。在锰钢牌号[w(Mn): 6-20%,w(Al): 0.025%]的情况下，溶解Mn对sio2的还原比溶解Al的还原要深刻得多，导致炉渣中MnO的增加。当Mn含量足够高时，如w(Mn) = 20%，炉渣中的MgO与钢中溶解的Mn之间的反应也非常明显。高矿渣碱度可以抑制溶解Mn对sio2的还原，但MgO和Mn仍可以在矿渣中发生反应生成MnO。锰钢牌号推荐使用高碱度精炼渣（rbbb40）。
Some laboratory experiments are carried out to investigate the reaction between manganese steel and ladle slag. It is found that as expected when the slag basicity [R=w(CaO)/w(SiO2)] is sufficiently low, for example,R< 4, the dissolved Al in conventional Al‐killed steel could reduce the SiO2component of the slag. In the case of manganese steel grades [w(Mn): 6–20%,w(Al): 0.025%], the reduction of SiO2by dissolved Mn becomes much more profound compared with that by dissolved Al, resulting in the increase of MnO in slag. When the Mn content is high enough, for example,w(Mn) = 20%, the reaction between the MgO in slag and the dissolved Mn in steel is also very evident. High slag basicity can restrain the reduction of SiO2by dissolved Mn, but the reaction between MgO and Mn can still take place to generate MnO in slag. High‐basicity refining slag (R >4) is recommended for manganese steel grades.
