| description | A non-oriented electrical steel sheet according to an embodiment of the present invention comprises: a steel sheet base material containing, in wt%, 2.0-6.5% of Si, 0.1-1.3% of Al, 0.3-2.0% of Mn, and 0.005-0.06% of Cr, with the remainder comprising Fe and inevitable impurities; and an insulation coating disposed on the steel sheet base material, wherein Expression 1 is satisfied before stress relief annealing and Expression 2 is satisfied after stress relief annealing. Expression 1: 0.1 ⿥ [Mn coating] / [Mn50], Expression 2: 10 ⿥ [Mn coating] / [Mn50] ⿥ 1 (In Expression 1 and Expression 2, [Mn coating] represents the average Mn content (wt%) in the insulation coating, and [Mn50] represents the Mn content (wt%) at a depth of 50 μm into the steel sheet base material from the interface between the steel sheet base material and the insulation coating).
Una chapa de acero eléctrico no orientado de acuerdo con una modalidad de la presente invención incluye: un material base de chapa de acero que contiene, por % en peso: 2,0 a 6,5 % de Si, 0,1 a 1,3 % de Al, 0,3 a 2,0 % de Mn, 0,005 a 0,06 % de Cr, y un equilibrio de Fe y otras impurezas inevitables; y una película de revestimiento aislante colocada sobre el material base de chapa de acero, en la que la Fórmula 1 siguiente se satisface antes del recocido de alivio de tensiones, y la Fórmula 2 siguiente se satisface después del recocido de alivio de tensiones. [Fórmula 1] 0,1 = [película de revestimiento de Mn]/[Mn50] [Fórmula 2] 10 = [película de revestimiento de Mn]/[Mn50] = 1 (en las fórmulas 1 y 2, [película de revestimiento de Mn] se refiere a un contenido medio de Mn (% en peso) en la película de revestimiento aislante, y [Mn50] se refiere a un contenido de Mn (% en peso) a una profundidad de 50 µm desde una interfaz entre el material base de chapa de acero y la película de revestimiento aislante hacia un interior del material base de chapa de acero). |
