摘　　要：对高牌号无取向电工钢35W300的成品进行了第二次退火,对第二次退火后的成品性能、纵横向磁性能差异和组织变化进行了分析。结果表明,随着第二次退火温度的升高,晶粒长大,磁性能优化。铁损平均值下降0.087 5W/kg,磁感平均值升高0.008T。第二次退火温度为820℃的产品的磁性能能够满足用户使用要求。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 ℃.
