Effect of Normalizing Annealing Treatment on Microstructure and Texture of Non-oriented Silicon Steels

The effect of normalizing annealing treatment on microstructure and texture of non-oriented silicon steel hot rolled plates and final products were investigated by means of optical microscope and X-ray diffractometer analysis. The results show that the deformed microstructure of the hot rolled plates transformed into recrystallized grain after normalizing annealing treatment. The grains of Goss texture and cubic texture crystallographic orientation were formed and grown by recrystallization in the deformation bands. The intensity of 111 and 112 unfavorable texture of the final products was decreased, and intensity of the 100 and 110 favorable texture was increased significantly. So the magnetic properties of the non-oriented silicon steel final products were improved obviously.
