试验的铸态取向硅钢（/%:0.044⁰.056C,3.12³.32Si,0.08⁰.11Mn,0.002⁰.008S,0.002 9⁰.029 1Als,0.006 2⁰.010 9N）由30 kg高频真空感应炉熔炼。通过场发射扫描电子显微镜/能谱仪（FE-SEM/EDS）研究结果表明,0.002 9%Als钢中氧化物主要为SiO₂,存在片状、棒状及近似球状的独立MnS,未发现含铝的氧化物或氮化物;0.0090%Als钢中出现以Al₂O₃为主的复合氧化夹杂物,存在MnS与AlN的复合析出物。钢中Als增加,复合析出物多呈簇状发展。氧化物容易成为MnS-AlN复合析出的核心,钢中Als含量越低,夹杂物中的MnS含量越高;作为核心的氧化物夹杂的尺寸越小,形成的复合夹杂物的形状越规则,尺寸也越小。热力学计算结果表明,钢中Als含量主要影响了钢中氧化物夹杂的组成和AlN的析出温度及析出量。 Test as-cast grain-oriented silicon steel（/%:0.044 ⁰.056C,3.12 3.32Si,0.08 0.11Mn,0.002⁰.008S,0.002 9⁰.029 1 Als,0.006 2⁰.010 9N） is melted by a 30 kg high frequency vacuum induction furnace.The research results by using field emission-scanning electron microscope/energy dispersive spectrometer（FE-SEM/EDS） show that in 0.002 9%Als steel the main oxide is SiO₂,and there is independent laminable,rod-like and approximate ...
