摘　　要：影响无取向电工钢磁性能的两个主要因素是组织和织构。研究表明:随着牌号的升高,晶粒尺寸增大,有利于铁损的降低;(Si+Al)含量变化时,主要织构组成不变,但是随着(Si+Al)含量的增加,有利的高斯织构{110}<001>强度由4.0减少到2.0,不利织构γ的强度由15.1增加到20.6;可以通过改善轧制工艺减少不利织构,提高磁感。The main two factors which have influences on the magnetic properties of non-oriented electrical steel are microstructure and texture. The thesis states that the increases in steel grade and the size of crystal particles contribute to the decrease in iron loss. When the content of Si and Al changes, the main constitution of texture almost don＇ t change, but the strength of the favorable Goss texture is reduced from 4.0 to 2.0, while the strength of the adverse γ texture is increased from 15.1 to 20.6. Therefore, the magnetic induction could be increased by means of improving the rolling technology to reduce adverse texture.
