Abstract

Abstract: Evolution of microstructure and magnetic properties of non-oriented silicon steel with different composition systems after secondary annealing by same process was studied. The results show that the ferrite grain size of non-oriented silicon steel is further increased and the magnetic properties are improved after secondary annealing treatment. The potential for improving the magnetic properties of non-oriented silicon steel is related to the composition, and is independent of the annealing temperature of the product. Among these composition systems, the ferrite grains of non-oriented silicon steel with high Al composition system are easier to grow up after secondary annealing treatment, and the magnetic properties is the best. The average grain size can reach 159 μm, and the core loss reduction is 1.14 W/kg. Besides, the magnetic induction of non-oriented silicon steel under low magnetizing force is significantly improved after secondary annealing treatment, and then the magnetic conductivity under low magnetizing force is improved. In the range of 0.5-1.5 T of motor working magnetic induction, the magnetic conductivity of non-oriented silicon steel after secondary annealing treatment is significantly higher. The core of the compressor motor is suitable for using non-oriented silicon steel with high Al composition system.
