| 摘 要： | 研究了CSP流程试制50W270高牌号无取向硅钢热轧→常化→冷轧→退火过程中织构的演变.利用电子背散射衍射技术对全流程织构进行测量和分析.发现热轧板织构在厚度方向上存在较大差异，表层主要为铜型、黄铜和高斯织构，1/4层存在微弱的高斯织构和旋转立方织构，中心层以γ纤维织构和旋转立方织构为主，还含有较弱的α纤维织构.与热轧板相比，常化板表层和1/4层织构变化不大，中心层旋转立方织构和α纤维织构增强.冷轧板各层均具有α纤维织构和γ纤维织构.与冷轧板相比，成品板各层中α纤维织构基本消失，还出现了立方织构和高斯织构.

| Abstract: | This article focuses on texture evolution in 50W270 high-brand non-oriented silicon steel produced by CSP in hot rolling, normalizing, cold rolling, and annealing processes. The texture in the whole process was measured and analyzed by electron back-scatter diffraction. It is found that the texture along the thickness direction in hot-rolled strips changes obviously:there are mainly copper, brass, and Goss textures in the surface layer; the 1/4 layer has weak Goss texture and rotating cube texture; γ-fiber texture, rotating cube texture, and weak α-fiber texture appear in the center layer. Compared with hot rolled strips, the texture changes little for the normalized strip surface and 1/4 layer, but rotating cube texture and α-fiber texture are enhanced in the center layer. Quite strong α-fiber texture and γ texture appear in every layer for cold-rolled strips. Compared with cold-rolled strips, α-fiber texture almost disappears, but cube texture and Goss texture appear in annealed strips. |
