Abstract | Provided is a non-oriented electromagnetic steel sheet that has exceptional recyclability and does not undergo instability of the magnetic characteristics when the Al content is reduced in anticipation of reusing the non-oriented electromagnetic steel sheet as scrap iron. The elemental composition, expressed in mass%, is 0.0050% or less of C, 1.0%-4.0% of Si, 0.10%-3.0% of Mn, less than 0.0050% of Sol.Al, more than 0.01% and up to 0.20% of P, 0.0050% or less of S, 0.0050% or less of N, at least 0.02% and less than 0.10% of Cu, and 0.0005%-0.0100% of Ca, the balance being Fe and unavoidable impurities.
La présente invention concerne une tôle d'acier électromagnétique non orienté qui présente une aptitude exceptionnelle au recyclage et qui ne subit pas une instabilité des caractéristiques magnétiques lorsque la teneur en Al est réduite en anticipation de la réutilisation de la tôle d'acier électromagnétique non orienté en tant que ferraille. La composition élémentaire, exprimée en % en masse, est inférieure ou égale à 0,0050 % de C, de 1,0 % à 4,0 % de Si, de 0,10 % à 3,0 % de Mn, inférieure à 0,0050 % de Sol.Al, supérieure à 0,01 % et jusqu'à 0,20 % de P, inférieure ou égale à 0,0050 % de S, inférieure ou égale à 0,0050 % de N, au moins de 0,02 % et inférieure à 0,10 % de Cu et de 0,0005 % à 0,0100 % de Ca, le reste étant constitué de Fe et d'impuretés inévitables.
無方向性電磁鋼板を鉄スクラップとして再利用することを所期してAl含有量を低くした場合に、磁気特性が不安定になることのない、リサイクル性に優れた無方向性電磁鋼板を提供する。 質量%で、C:0.0050%以下、Si:1.0%以上 4.0%以下、Mn:0.10%以上 3.0%以下、Sol.Al:0.0050%未満、P:0.01%超え0.20%以下、S:0.0050%以下、N:0.0050%以下、Cu:0.02%以上0.10%未満およびCa:0.0005%以上 0.0100%以下を含有し、残部はFeおよび不可避的不純物の成分組成とする。 |
