摘　　要：研究了退火温度对薄规格35W440电工钢织构和磁性能的影响规律。结果表明:连续退火温度的改变可以明显影响产品磁性能,随着退火温度的提高,对应的铁损P1.5/50呈下降趋势,高温段下降缓慢;磁感B50基本呈单调递减,但在高温阶段下降缓慢;退火温度对成品织构类型影响较小,但对相应的织构组分强度影响较大。The effect of annealing temperature on texture and magnetic properties of thin gauge non-oriented silicon steel 35W440 is investigated. The results show that different continuous annealing temperature can significantly impact magnetic properties of prodults. With temperature increasing, core loss P1.5/50 gradually decreases,and it decreases slowly in high temperature stage;magnetic induction B50 monotonically declines, and it declines slowly in high temperature stage. The effect of normalizing temperature on the texture types of normalized plates is small,but on the intensity of the texture component is significantly.
