研究了二次冷轧压下率对无取向硅钢薄带磁性能和织构的影响，结果表明：采用二次冷轧工艺时，55%左右的二次冷轧压下率能够获得磁性能优良的0.2 mm厚无取向硅钢薄带。当二次冷轧压下率高于55%后，成品钢带中对磁性能不利的γ织构组分比例逐渐增强，特别是{111}<112>、{111}<110>织构。采用55%左右的二次冷轧压下率制造能获得{100}面织构和高斯织构比例都较高的产品，其铁损P1.0/400能够降低到10.6 W/kg,同时磁感B50能达到1.68 T。
The effect of cold rolling reduction rate on magnetic properties and texture of thin nonoriented electrical steel sheets were researched. The results showed that thin nonoriented electrical steel sheets with better magnetic properties could be produced with 55% reduction rate of secondary cold rolling. The portion of unfavorable γtexture components, especially {111}<112> and {111}<110> was increased when the rate of secondary cold rolling reduction was higher than 55%.The thin nonoriented electrical steel sheets manufactured with a rate of secondary cold rolling reduction of 55% had more {100} and Goss texture,and of which P1.0/400 could be reduced to 10.6 W/kg and B50 could reach to 1.68 T.
