摘要

本文研究了退火工艺对硅含量3.0%的薄规格高性能硅钢高频磁性能影响规律。研究结果表明,随着退火温度在860℃~1000℃范围内逐步提高,P_(1.0/400)先下降后上升的趋势,在退火温度为940C时P_(1.0/400)达到15.7 W/kg最低值:平均晶粒尺寸增大,且涡流损耗比例逐步增大;随着连续退火温度提高,有利织构组分略增加,但不利织构组分显著增加,且形成"γ通道",磁感B_(50)呈下降趋势。
The effect of annealing process on of high frequency magnetic properties of 0.3mm thickness non-oriented high performance silicon steel was investigated in this paper.The results show that annealing temperature at 860~1000℃ can significantly change the magnetic properties.With the increase of annealing temperature,the high frequency iron loss P_(1.0/400) value is firstly decreased and then increased,the lowest value of that is 15.7W/kg at 940℃,as well as,the average grain size and percentage of eddy current loss increase.There is little effect of annealing temperature on the favorable texture types of finished plates,but the effect on intensity ofγ-fiber texture components of the finished plates is significantly increased,and the formatting of y-channel appears.However,the magnetic induction is gradually decreasing.
