摘要/Abstract

摘要： 试验的铸态取向硅钢(/%:0.044~0.056C,3.12~3.32Si,0.08~0.11Mn,0.002~0.008S,0.0029~0.0291Als,0.0062~0.0109N)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,0.0029%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。

Abstract: Test as-cast grain-oriented silicon steel (/% : 0.044-0.056C, 3.12-3.32Si, 0.08-0.11 Mn, 0.002-0.008S, 0.0029-0.0291 Als, 0.0062-0.0109N) 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 0.0029% Als steel the main oxide is SiO₂, and there is independent laminable, rod-like and approximate spherical shape MnS while the oxide or nitride bearing aluminium has not been found in steel ； in 0. 0090% Als steel the composite oxide containing prime A1₂O₃ occurs and there is MnS-AlN compounded precipitate; with increasing Als in steel the compounded precipitate develops in a cluster form.The oxide particle is easily becoming a nucleus of MnS-AIN compounded precipitating, and the lower Als content in steel the higher MnS content in inclusion； the smaller oxide as nucleus the more regular morphology of formed compounded inclusion and smaller its size. The thermodynamic calculation results show that the Als content in steel is the main factor to influence on the ingredient of oxide inclusion in steel and the precipitating temperature and amount of AIN in steel.
