Effects of microstructure and precipitation on magnetic property of non-oriented silicon steel sheets after annealing for high-efficiency motor are studied in the paper by experiments.The annealed sheet exhibits a larger average grain size,obviously decreasing iron loss and slightly raising magnetic induction with increasing temperature.The annealed sheet has better comprehensive properties at a annealing temperature of 1 000℃.The main precipitates are compounds of AlN、(MnS+AlN)and(MnS+Al2O3) with coarse size of 1.0~2.5 μm.Besides,a few fine AlN and TiN with size below 100 nm are found.Iron loss of electrical steel simulated by TSCR process in laboratory is 4.00 W/kg and magnetic induction is more than 1.75 T.It is suitable for producing iron cores for small and medium sized high-efficiency motors.
