摘要 以不同高斯取向度的取向硅钢成品板为初始原料,采用一次冷轧法制备0.06~0.12mm厚的取向硅钢薄带。利用EBSD取向成像技术研究冷轧压下率以及初始高斯晶粒取向度对超薄取向硅钢织构演变与磁性能的影响。结果表明:随着冷轧压下率增大和厚度减小,退火后再结晶织构增强,当压下率为70%时,再结晶织构中RD//〈001〉织构最锋锐,磁性能最佳;初始样品高斯取向度越高,制备的薄带样品磁性能越好;因此,生产高性能的取向硅钢薄带应选用初始高斯晶粒取向度较高的成品板。

Abstract:The ultra-thin grain-oriented silicon steel strips with a thickness of 0.06-0.12mm were produced by one-step-rolling methods with different Goss-orientation of grain-oriented silicon steel sheets. The effect of cold rolling reduction and initial Goss-orientation of samples on texture evolution and magnetic performance of ultra-thin grain-oriented silicon steel strips was studied by EBSD. The result shows that with the increase of cold rolling reduction and decrease of strips thickness, the recrystallization texture is enhanced after annealing.When the cold rolling reduction is 70%,RD//〈001〉 recrystallization texture is the sharpest, and the magnetic performance is the best. The higher degree of Goss orientation in initial sample is, the better magnetic performance of ultra-thin grain-oriented silicon steel.Therefore, for producing an ultra-thin grain-oriented silicon steel with high performance, a material with a concentrated orientation of Goss grains can be used.
