摘　　要：取向硅钢是一种重要的软磁材料,硅酸镁底层是产品结构的重要组成部分,其控制难度较大,其质量严重影响着取向硅钢的表面质量。氧化层、退火气氛、退火温度及氧化镁等因素的不确定性都会导致硅钢成品产生缺陷,在一定程度上限制了取向硅钢产业的发展,因此本文根据取向硅钢的工艺特征,结合国内外研究对上述因素对硅酸镁底层的影响进行了总结,并提出今后有待进一步研究的方向。Grain-oriented silicon steel is a critical soft magnetic material,and the silicate magnesium layer is an integral part of the product structure,which presents significant challenges in control.The quality of the silicate magnesium layer has a profound impact on the surface quality of grain-oriented silicon steel.The uncertainty in factors such as the oxide layer,annealing atmosphere,annealing temperature,and magnesium oxide can lead to defects in the final silicon steel product,thereby limiting,to some extent,the development of the grain-oriented silicon steel industry.Therefore,this paper summarized the influence of these factors on the silicate magnesium layer based on the process characteristics of grain-oriented silicon steel and the research conducted both domestically and internationally.Additionally,it identifies areas that require further study in the future.
