| 摘 要： | 当常化温度由850℃提高至1 100℃,0.005%E-3.0%Si无取向电工钢2.5 mm热轧板的平均晶粒尺寸由60μm增至200μm;当热轧板常化温度为1 000℃,0.5 mm冷轧板850℃+950℃退火后的晶粒尺寸最大,为105μm。随热轧板常化温度提高,冷轧板退火后{111}、{112}和{114}织构明显减弱,{100}织构增强,热轧板最佳常化温度为900～1 050℃,该电工钢的铁损最低。

| Abstract: | The test results showed that with increasing normalizing temperature from 850 ℃ to1100 ℃,the average grain size of 2.5 mm hot rolled plate of 0.005C-3.0Si non-oriented electric steel increased from 60 μm to 200 μm,and with normalizing at 1000 ℃ for hot rolled plate,the grain size of 0.5 mm cold rolled sheet annealed at 850 ℃+950 ℃ was maximum to 105 μm; with increasing normalizing temperature of hot rolled plate,the{111},{112} and{114}tex ture in annealed cold rolled sheet obviously weakened and the{100|texture was enhanced. The optimum normalizing temperature of hot rolled plate was 900~1050 ℃,with which the iron loss of the electric steel was lowest. |
