The principle and method of analysis of the crystallographic planes standard equator plane projection are described in this article. Under different technological using similar Fe-3% Si silicon steel samples, conventional grain oriented silicon steel, 1150°C conventional hot-rolled grain oriented silicon steel and non-oriented silicon steel are obtained, respectively. Their pole figures of {200} planes for the samples are also obtained with XRD. The results state that the conventional Fe-3% Si grain oriented silicon steel has good Gauss texture, and 1150°C conventional hot-rolled grain oriented silicon steel has weak Gauss texture, meanwhile, non-oriented silicon steel has no Gauss texture, which prove the process has great the effect on the texture.
