摘　　要：运用电子背散射衍射(EBSD)技术,研究了50W600无取向硅钢在热轧→冷轧→退火工序间织构的演变。结果表明:由于热轧板沿板厚方向的应力场和温度场存在差异,导致热轧板不同层织构类型和强度存在差异;热轧板表层主要存在铜型、黄铜和高斯织构,1/4层织构主要为α纤维织构和较弱的高斯织构,中心层织构较单一,主要为α纤维织构;和热轧板相比,冷轧板各层织构差异较小,为典型的轧制织构(α纤维织构和γ纤维织构);退火板各层都表现为γ纤维织构增强、α纤维织构减弱,旋转立方织构基本消失。The texture evolution of 50W600 non-oriented silicon steel in hot rolling, cold rolling and annealing process was investigated by electron back-scatter diffraction （EBSD） technology. Results show that the hot rolled plate texture types and intensities along thickness direction were different Because of the different stress fields and temperature fields. The major texture types in the surface of hot rolled plate were copper, brass and Gauss texture. The texture was composed of α fibre texture and weaker Gauss texture in 1/4 layer. And the texture in the center layer was almost α fibre texture. Compared with hot rolled plate, the texture type difference among layers of cold rolled plate was smaller. They were all typical rolling texture （α fibre texture and 7 fiber texture）. In each layer of annealed plate, the γ fiber texture was enhanced, the α fibre texture weakened and the rotate cube texture disappeared basically.
