作了一项有关不同含锰量的钢水的脱氧方面的研究。电子显微探针分析证实了在这些钢水中只有在溶解的氧含量大大超过出钢前低碳钢中所通常有的量时,才能形成被矾土包封的铁尖晶石(Fe·O·Al_2O_3)或锰尖晶石(MnO·Al_2O_3)这一类双相夹杂物。因为这些复合氧化物在铝存在的情况下是亚稳的,随足够的保留时间它们还原成铝。这导致关于钢中尖晶石型夹杂物可能的形成机理的结论是与引起氧富集的钢再氧化有关。
A study was conducted on the deoxidation of molten steel with different manganese content. Electron microprobe analysis confirmed that the bauxite-coated iron spinel (FeO) was formed in these molten steels only when dissolved oxygen levels significantly exceeded those normally found in low carbon steels before tapping · Al 2 O 3) or manganese spinel (MnO · Al 2 O 3). Because these composite oxides are metastable in the presence of aluminum, they are reduced to aluminum with a sufficient retention time. This has led to the conclusion that the possible formation mechanism of spinel-type inclusions in steel is related to reoxidation of the steel that causes oxygen enrichment.
