| Abstract: | The product of high grade non-oriented electrical steel 35W300 was annealed at the second time. Micro- structure, the difference of magnetic properties in the vertical and horizontal and were studied. The results show that the grain grew up and magnetic properties optimized with the increase of annealing temperature for the second time. Iron loss average declines in 0. 0875 W/kg, magnetic induction average increases 0. 008 T. The magnetic properties can meet the requirements of users at the second annealing temperature in 820 ℃. |
