稀土对无取向硅钢组织和性能的影响研究现状

Research Status of Effects of Rare Earth on Microstructure and Properties of Non-oriented Silicon Steel

无取向硅钢作为一种极为重要的软磁性材料,广泛应用于电机、变压器等电器设备中。近年来随着科技的不断发展,节能减排要求的日益提高,对铁芯材料性能提出了更高的要求。稀土元素添加作为一种重要的合金化手段,对无取向硅钢的性能有着显著影响并受到广泛关注。文章总结了稀土元素对无取向硅钢夹杂物、织构及磁性能的影响,并针对目前研究现状,提出未来的发展方向。

As a type of very important soft magnetic material,non-oriented silicon steel is widely used in such electrical equipment as motor and transformer.In recent years,with the continuous development of science and technology,the requirements of energy conservation and emission reduction are increasing so that the requirements for performances of iron core material are higher.As an important alloying method,the addition of rare earth elements has significant effects on the properties of non-oriented silicon steel and has been widely concerned.In this paper,the effects of rare earth elements on inclusions,texture and magnetic property of non-oriented silicon steel are summarized as well as the future development direction is proposed according to present research status.
