Non-oriented electrical steel plate with high magnetic induction and low iron loss and manufacturing method thereof

The invention discloses a non-oriented electrical steel plate with high magnetic induction and low iron loss. The non-oriented electrical steel plate comprises, by mass, 0.001-0.004% of C, 1.6-3.5% ofSi, 0.1-1.0% of Mn, 0.15-2.0% of Al, 0-0.002% of Ti, 0.003-0.2% in total of one or both of Sb and Sn, and the balance Fe and other inevitable impurities. In addition, the invention discloses a continuous annealing process and manufacturing method of the non-oriented electrical steel plate with high magnetic induction and low iron loss. The manufacturing method comprises the following steps: smelting and casting, hot rolling, normalizing, cold rolling, implementation of the continuous annealing process, and covering with an insulating coating, thereby obtaining the non-oriented electrical steel plate with excellent magnetic performance. 本发明公开了一种高磁感低铁损的无取向电工钢板，其化学元素质量百分比为：C：0.001-0.004％；Si：1.6-3.5％；Mn：0.1-1.0％；Al：0.15-2.0％；Ti：0-0.002％；Sb、Sn中的一种或两种，其总含量为0.003-0.2％；余量为Fe和其他不可避免的杂质。此外，本发明公开了上述的高磁感低铁损的无取向电工钢板的连续退火工艺。另外
