研究了模拟TSCR流程生产的低碳低硅无取向电工钢在热轧-冷轧-退火过程中织构的演变。对热轧板采用EBSD技术进行织构的测定,而对冷轧板和退火板采用X射线衍射技术进行了织构的测定。结果表明:热轧板沿板厚方向织构变化比较明显,在1/10处主要织构为α纤维织构和γ纤维织构;在1/4厚度处出现了较强的γ纤维织构;在1/2厚度处主要为较强的{001}〈110〉织构,其他织构分布漫散。冷轧板表面和中心处主要织构均为α纤维织构和γ纤维织构,但是在中心处两织构强度都显著减弱。退火板表面和中心处α纤维织构基本消失,γ纤维织构织构进一步加强,出现了{110}〈001〉高斯织构和{001}〈010〉立方织构。
The evolution of the texture of low carbon and low silicon non-oriented electrical steel produced by TSCR process during hot rolling, cold rolling and annealing was studied. The hot-rolled sheet using EBSD technology for the determination of texture, while the cold-rolled sheet and annealed plate using X-ray diffraction technology for the determination of texture. The results show that the textures of the hot-rolled sheet vary obviously along the thickness of the hot-rolled sheet. At 1/10, the main texture is α-fiber texture and γ-fiber texture. At ¼ thickness, the stronger γ-fiber texture Mainly in the {001} <110> texture at ½ thickness, with other textures distributed diffusely. The main textures on the surface and in the center of the cold-rolled sheet are both α-fiber and γ-fiber textures, but the two textures are significantly weakened at the center. The α fiber texture at the surface and the center of the annealed sheet basically disappeared, and the γ fiber texture was further strengthened. The {110} <001> Gaussian texture and {001} <010> cubic texture appeared.
