摘要/Abstract

摘要： 研究了退火温度对硅质量分数为2.5 %的硅钢组织和磁性能的影响规律。结果表明：当退火温度从850 ℃提高至1 050 ℃时，P1.5/50呈先下降后缓慢上升的趋势，且在950 ℃时达到最低，P1.0/400呈先下降后上升的趋势，在900 ℃时达到最低；随着退火温度的升高，有利织构组分强度逐渐降低，磁感B50呈单调递减趋势。

Abstract: The effect of annealing temperature on microstructure and magnetic properties of nonoriented silicon steel containing 2.5 %Si was investigated in this paper. The results showed that, the effect of annealing temperature on magnetic properties is obvious, with the increase of annealing temperature from 850 ℃ to 1 050 ℃, the iron loss P1.5/50 value is firstly decreased and then increases slightly, and reaches the lowest at 950 ℃, P1.0/400 value is firstly decreased and then increased, and reaches the lowest at 900 ℃. With the increase of annealing temperature, the strength of beneficial texture components decreases gradually, and the magnetic induction B50 decreases monotonously.
