无方向性电磁钢板及其制造方法
Abstract:
化学成分中，以质量％计含有C：0.0001～0.01％、Si：0.05～7.0％、Mn：0.01～3.0％、Al：0.0020～3.0％、S：0.0001～0.1％、P：0.0010～0.15％、N：0.0010～0.01％、Cu：0.01～5.0％，剩余部分包含Fe和杂质，对电解提取残渣进行的X射线衍射中所得的、2θ＝46.4°时出现的具有Hexagonal结构的Cu硫化物的衍射强度I2θ＝46.4、与2θ＝32.3°时出现的具有Cubic结构的Cu硫化物的衍射强度I2θ＝32.3满足I2θ＝46.4/I2θ＝32.3≤0.5。
Abstract(English):

The invention provides a non-oriented magnetic steel sheet and a method for producing the same. In the present invention, the chemical components include, by mass%, 0.0001-0.01% of C, 0.05-7.0% of Si, 0.01-3.0% of Mn, 0.0020-3.0% of Al, 0.0001-0.1% of S, 0.001-0.15% of P, 0.0010-0.01% of N, and 0.01-5.0% of Cu, the remainder comprising Fe and impurities. I2[Theta]=46.4, which is the diffraction intensity of copper sulfide having a hexagonal structure arising at 2[Theta]=46.4 DEG obtained by means of X-ray diffraction with respect to an electroextraction residue, and I2[Theta]=32.3, which is the diffraction intensity of copper sulfide having a cubic structure arising at 2[Theta]=32.3 DEG, satisfy I2[Theta]=46.4/I2[Theta]=32.3<=0.5.
