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。
Using EBSD detection technology, the evolution of the texture of 50W800 non-oriented electrical steel during the important production processes and the difference of texture in the strip width direction were analyzed. The results show that the difference of hot-rolled plate texture in the strip width direction is mainly reflected in the surface texture. The surface texture of the strip edge is mainly composed of the cubic texture of rotation, α-fiber texture and a small amount of γ-fiber texture. The surface texture at 1/4 of the strip width mainly has Gaussian texture and the strip width 1/2 At the surface of the texture is mainly (110) texture and a small amount of copper texture. The strip width at 1/4 and 1/2 of the texture types are basically the same, with the α-fiber texture and the rotating cube-based texture. After cold rolling, the difference of the surface texture types in all the places is small, which are γ-fiber texture and α-fiber texture. The value of texture intensity gradually decreases from the edge of the plate to the center. After annealing, the texture of the components are basically the same everywhere, for the stronger γ-fiber texture and weaker (100) -face texture. The difference in texture strength values of all parts is small, and the trend of change is consistent with that of cold rolled plates.
