Abstract

A high-magnetic-induction low-iron-loss non-oriented silicon steel sheet and a manufacturing method therefor. The chemical composition by mass percentages is: C≤0.005%, Si: 0.1%-1.6%, Mn: 0.1%-0.5%, P≤0.2%, S≤0.004%, Al≤0.003%, N≤0.005%, Nb≤0.004%, V≤0.004% and Ti≤0.003%, with the balance being Fe and inevitable impurities; and at the same time satisfies: 120≤[Mn]/[S]≤160, and [Nb]/93+[V]/51+[Ti]/48+[Al]/27≤[C]/12+[N]/14. After casting, the cooling rate in a cool-down process of casting slab is controlled, and a temperature controlling method is used to adjust the charging temperature of casting slab.
