Abstract The texture from the first cold rolling to the primary recrystallization of low temperature slab reheating grain-oriented electrical steel were researched by orientation distribution function and orientation distribution intensity technique. The results show that after the first stage of cold rolling, there is a strong {001}<110> texture in the subsurface and the texture in center layer is very similar to the center layer of hot band which has strong {001}<110> and {112}<110> texture, due to the heredity. After intermediate annealing the microstructure indicates full recrystallization throughout the sheet thickness. Additionally, the strength of each texture is weakened and the Goss orientation reappears in all layers. There was very little through-thickness variation of the texture after the second stage of cold rolling, exhibiting major {111}<112> and minor {001}<110> components. After primary recrystallization the texture are qualitatively similar from all layers with the {111}<110> is strongest and a certain intensity of Goss texture.
