摘　　要：采用EBSD检测技术,分析了50W800无取向电工钢在重要生产工序间织构的演变以及织构沿带钢宽度方向上的差异性。结果表明:热轧板织构沿带钢宽度方向上的差异性主要体现在表层织构。带钢边部表层织构主要由旋转立方织构、α纤维织构以及少量的γ纤维织构组成,带钢宽度1/4处的表层织构主要存在高斯织构,带钢宽度1/2处的表层织构主要为(110)面织构以及少量的铜型织构。各处的带钢宽度1/4处和1/2处的织构类型基本一致,都以α纤维织构和旋转立方织构为主。冷轧后,各处的表层织构类型差异较小,均为γ纤维织构和α纤维织构。由板宽边部至中心处织构强度值逐渐降低。退火后,各处织构的组分基本一致,为较强的γ纤维织构和较弱的(100)面织构。各处织构强度值差异较小,变化趋势与冷轧板一致。The texture of non-oriented electrical steel 50W800 was detected by EBSD technique.The evolution of the texture between important processes and the difference of texture along the width direction of strip were analyzed.The result shows that the difference along the width direction of strip of texture at the surface of hot rolled plate is most obvious.The texture at the surface of strip edge is primarily made of rotating cube texture,αfiber texture and weakγfiber texture.Goss texture is mainly composition of the texture of surface at 1/4of strip width.The texture of surface at 1/2of strip width is made of（110）surface texture and weak copper-type texture.The textures of surfaces at 1/2and 1/4of strip width are mainlyαfiber texture and rotating cube texture.After cold rolled,the texture at surface along the width direction of strip is made ofγfiber texture andαfiber texture.The intensity of texture decreases from the edge to the center of strip.After annealing,there are strongγfiber texture and weak（100）surface texture everywhere.After annealing,the difference on the intensity of texture everywhere is small and its change trends is the same as that of cold-rolled sheet.
