Abstract:
(EN) A non-oriented electrical steel sheet according to an embodiment of the present invention comprises, in wt%, 2.5 to 3.3% of Si, 0.05 to 1% of Al, 0.05 to 1% of Mn, 0.01% or less of S (not including 0%), 0.005% or less of N (not including 0%), 0.005% or less of C (not including 0%), 0.005% or less of Ti (not including 0%), 0.005% or less of Nb (not including 0%), 0.001 to 0.1% of P, 0.001 to 0.1% of Sn, and 0.001 to 0.1% of Sb, with the remainder being Fe and unavoidable impurities, and satisfies formulas 1 to 3 below. [Formula 1] 1.7 ≤ [Si]/([Al] + [Mn]) ≤ 2.9 [Formula 2] 50 ≤ 13.25+11.3*([Si]+[Al]+[Mn]/2) ≤ 60 [Formula 3] 0.025 ≤ [P]+[Sn]+[Sb] ≤ 0.15 (In formulas 1 to 3, [Si], [Al], [Mn], [P], [Sn], and [Sb] represent the content (in wt%) of Si, Al, Mn, P, Sn, and Sb, respectively.)
(FR) Selon un mode de réalisation, cette invention concerne une tôle d'acier électrique à grains non orientés, comprenant, en % en poids, 2,5 à 3,3 % de Si, 0,05 à 1 % d'Al, 0,05 à 1 % de Mn, (à l'exclusion de 0 %), pas plus de 0,01 % de S (à l'exclusion de 0 %), pas plus de 0,005 % de N (à l'exclusion de 0 %), pas plus de 0,005 % de C (à l'exclusion de 0 %), pas plus de 0,005 % de Ti (à l'exclusion de 0 %) pas plus de 0,005 % de Nb, 0,001 à 0,1 % de P, 0,001 à 0,1 % de Sn, et 0,001 à 0,1 % de Sb, le reste étant du Fe et les inévitables impuretés, et satisfaisant les Formules 1 à 3 ci-après. [Formule 1] 1,7 ≤ [Si]/([Al]+[Mn]) ≤ 2,9; [Formule 2] 50 ≤ 13,25 + 11,3*([Si]+[Al]+[Mn]/2) ≤ 60; [Formule 3] 0,025 ≤ [P]+[Sn]+[Sb] ≤ 0,15 (dans les Formules 1 à 3, [Si], [Al], [Mn], [P], [Sn] et [Sb] représentent la teneur (en % en poids) en Si, Al, Mn, P, Sn et Sb, respectivement).
(KO) 본 발명의 일 실시예에 의한 무방향성 전기강판은 중량%로, Si : 2.5 내지 3.3%, Al : 0.05 내지 1%, Mn : 0.05 내지 1%, S : 0.01%이하(0%를 포함하지 않는다), N : 0.005%이하(0%를 포함하지 않는다), C : 0.005% 이하(0%를 포함하지 않는다), Ti : 0.005% 이하(0%를 포함하지 않는다), Nb : 0.005% 이하(0%를 포함하지 않는다), P : 0.001 내지 0.1%, Sn : 0.001 내지 0.1%, 및 Sb : 0.001 내지 0.1%를 포함하고, 잔부는 Fe 및 불가피한 불순물을 포함하고, 하기 식 1 내지 식 3를 만족한다. [식 1] 1.7 ≤ [Si]/([Al] + [Mn]) ≤ 2.9 [식 2] 50 ≤ 13.25+11.3*([Si]+[Al]+[Mn]/2) ≤ 60, [식 3] 0.025 ≤ [P]+[Sn]+[Sb] ≤ 0.15 (단, 식 1 내지 식 3에서 [Si], [Al], [Mn], [P], [Sn] 및 [Sb]은 각각 Si, Al, Mn, P, Sn 및 Sb의 함량(중량%)을 나타낸다.)
