6.5wt% Si electrical steel is a superior soft magnetic material with excellent magnetic properties which highly depends on texture. In this study, based on the heredity of 〈001〉 orientation in columnar grains, columnar grains are used as the initial material to prepare non-oriented 6.5wt% Si electrical steel with excellent magnetic properties. EBSD and XRD techniques are adopted to explore the structure and texture evolution during hot rolling, warm rolling, cold rolling and annealing. The results show that, due to the heredity of “structure and texture” from the initial strong {100} columnar grains, annealed sheet with {100}〈001〉 texture had better magnetic properties, which can be used as non-oriented high-silicon electrical steel. Both preferred cube grain nucleation in deformed {113}〈361〉 grains in subsurface and coarse {100}〈001〉 deformed grains in center layer show the effect of initial columnar grains with {100} texture.
