Abstract: A non-oriented silicon steel and a production method are provided. The non-oriented silicon steel is prepared by using the processes of molten iron desulfurization, converter smelting, RH refining, continuous casting, hot rolling, acid tandem rolling, annealing, coating and finishing, and a chemical composition is as follows in mass percent: C?0.003%, S?0.008%, Si: 0.35%+?1, Mn: 0.15-0.25%, P: 0.04-0.06%, Sn: 0.015%+?2, Nb?0.004%, V?0.004%, Ti?0.005%, Mo?0.004%, Cr?0.03%, Ni?0.03%, Cu?0.03%, N?0.003% and the balance of Fe and inevitable inclusions. The non-oriented silicon steel has the iron loss P1.5/50?5.5 W/kg and the magnetic induction intensity B5000?1.75 when having the thickness of 0.5 mm, and desulfurization is not needed in the RH refining process.
