摘　　要：分别研究了常化温度对电工钢50W470组织和织构的影响。结果表明:随着常化温度的提高,对再结晶退火态织构类型无明显影响,但再结晶退火态的不利织构γ强度降低,且成品的平均晶粒尺寸增大,其对应的铁损P_(1.5/50)降低,磁感B_(50)增大。The effect of normalizing temperature on microstructure and texture of non-oriented silicon steel 50W470 is investigated. The results show that high normalizing temperature can signif- icantly improve the magnetic properties. With the increase of normalizing temperature, there is no significant effect on the texture types after recrystallization annealing, but the strength of adverse texture is decreased and average grain size is increased. Meanwhile, the core loss P1.5/50 is gradually decreased and the ＂magnetic induction Bs0 is monotonically increased.
