Non Oriented Electrical Steel Sheet And Manufacturing Method Therefor
Abstract: A non-oriented electrical steel sheet according to one embodiment of the present invention comprises, by wt%, 0.005% or less of C (excluding 0%), 1.2-2.7% of Si, 0.4-2.0% of Mn, 0.005% or less of S (excluding 0%), 0.3% or less of Al (excluding 0%), 0.005% or less of N (excluding 0%), 0.005% or less of Ti (excluding 0%), and the balance of Fe and inevitable impurities, wherein the following formula 1 is satisfied, and, in the steel sheet, the volume fraction of grains, in which the angle between {112} plane and a rolling plane is 15° or less, is 40-60%. [Formula 1] 0.3 = ([Si]+ [Al]-1.5)/[Mn] = 0.85 (In formula 1, [Si] and [Al], [Mn] represent the amounts (wt%) of Si, Al and Mn, respectively.)
