采用非水溶液电解方法来提取无取向硅钢中夹杂物。通过扫描电镜(SEM)观察结果表明:无取向硅钢中主要夹杂物为六棱柱的AlN、不规则硅酸盐及球状的铁的硫化物和氧化物,其中AlN夹杂尺寸在1~5μm,数量较多,还有部分AlN的复合夹杂。进一步研究了AlN复合夹杂形成机理,采用了Thermo-Calc热力学计算软件计算出该钢样中AlN、MnS析出温度分别为1 240℃、1 200℃,而Al2O3析出温度大于1 800℃,从而为AlN复合夹杂形成机理提供了一个理论依据。 Extracting inclusions from non-oriented silicon steel in non-aqueous electrolysis is a nondestructive method to gain inclusions.Scanning electron microscopy shows that the main inclusions in non-oriented silicon steel were hexagonal AlN,which was of large quantity,irregular silicate,spherical iron sulfide and oxide.The size of AlN inclusions ranged from 1to 5μm,and there were some duplex inclusions of AlN.To further study the formation mechanism of AlN duplex inclusions,Thermo-Calc thermodynamic... 

实验室模拟薄板坯连铸连轧(TSCR)流程制造高磁感取向硅钢,借助电子背散射衍射(EBSD)技术对不同Sn含量的热轧板织构进行了研究。研究结果表明:不同Sn含量热轧板表层及次表层均为高斯织构、铜型织构及黄铜织构的混合织构,中心层为{100}面织构;Sn含量为0.1%时,热轧板表层及次表层高斯织构组分最多,取向密度最大,成品磁感最高,达到1.875 T。 Texture of grain oriented silicon steel hot rolled by thin slab casting and rolling process(TSCR) in laboratory with different Sn contents was analyzed by electron back-scattered diffraction(EBSD).The results show that the hot rolled slabs with different Sn contents have the same texture,i.e.,Goss,Copper and Brass.Specifically,the texture of core layer is {100};While the hot rolled slab with 0.10% Sn,the surface layer and subsurface layer have a sharpness Goss texture and the finished products h... 

电工钢试样加工产生的剪切应力会恶化钢板的磁性,对不同牌号硅钢片的横向、纵向试样退火前后磁性能的变化进行研究,结果表明:无取向硅钢片在剪切过程中横向、纵向的磁性受到剪切应力影响是不一样的。 The electrical steel sample processing magnetic of electrical steel will worsen due to the shear stress of sample. In this paper,the magnetic change of transverse,longitudinal specimens of different type of silicon steel sheet before and after annealing are studied. The results show that the magnetic of non- oriented silicon steel sheet affected in the process of shear is not the same in horizontal and vertical direction.
