摘　　要：{100}织构因具有两个易磁化方向能够明显的提高磁性能,因此如何在表面获得具有{100}织构一直是无取向电工钢研究焦点。本文主要介绍了获得{100}织构的主要工艺方法及其基本原理,并结合实际生产过程对各工艺方法的优缺点进行了分析;一方面,优化无取向电工钢的成分,降低碳、锰元素含量以避免脱碳退火和真空退火,简化生产工艺;另一方面,调节升温速度、降温速度和退火气氛,使{100}晶面的表面能或弹性应变能最低,制备具有{100}织构柱状晶组织的无取向电工钢是今后的发展方向。Because{100}texture has two easy magnetization directions,which can significantly improve magnetization properfies,how to develop{100}texture is a focus for researchers and manufactures.In the paper,main manufacturing processes and basic principle are introdued,and their advantages and disadvantages in practical production are analyzed.On the one hand,the production process can be simplified by optimizing chemical compositions,such as reducing the content of C and Mn,which can avoid decarbufization annealing and vacuum annealing.On the other hand,the production of non-oriented electrical steels with{100}texture and columnar grains is the development trend in the future and can be produced by adjusting the heating rate,cooling rate and atmosphere in the annealing process,which can lead to surface energy or elastic strain energy at the lowest level.
