摘要: The present application discloses a non-oriented silicon steel for a driving motor of a new energy vehicle and a production method thereof. The silicon steel is produced sequentially by steel smelting, continuous casting, hot rolling, normalizing, acid washing, single stand cold rolling without pre-heating, annealing, cooling, coating, and finishing. During steel smelting, no Cu, Cr, Ni, Nb, V, and Ti are added. The silicon steel comprises the following chemical ingredients: Si: 2.95%-3.15%, Al: 0.75%-0.95%, Si+2Al: 4.6%-4.9%, Mn: 0.5%-0.7%, Sn: 0.03%-0.04%, C≤0.0025%, with the balance being iron, wherein Mn/S≥380, and Al/N≥200.In the present application, the strength is improved while the magnetic performance is ensured, to solve the problem in the prior art that the magnetic performance and strength cannot be pursued at the same time, thus meeting the requirements for use in driving motors of new energy vehicles.
