    摘要: PURPOSE: A non-oriented electrical steel sheet with excellent magnetic property and a manufacturing method thereof are provided to improve magnetic properties and to maintain section Vickers hardness at less than 140 while the distribution density of coarse complex inclusions increases at more than 0.02 number/mm^2. CONSTITUTION: A non-oriented electrical steel sheet with excellent magnetic property is made of Al(Aluminum) 0.7~2.7wt.%, Si(Silicon) 0.2~1.0 wt.%, Mn(Manganese) 0.2~1.7wt.%, N(Nitrogen) 0.001~0.004wt.%, S(Sulfur) 0.0005~0.004wt.%, residual Fe(Iron), and inevitable impurities. The Al, Mn, N, and S satisfy the following condition equations. A first condition equation is {[Al] + [Mn] )Δ2.0. A second condition equation is 0.002Δ {[N] + [S] )Δ0.006. A third condition equation is 230Δ{([Al]+[Mn])/([N]+[S])}Δ1,000. The fraction of a cube crystal texture of a steel section is more than 3%.
