Title: NON-ORIENTED ELECTROMAGNETIC STEEL SHEET
Abstract:
When [Si] represents the Si content (mass%), [Al] represents the Al content (mass%), and [Mn] represents the Mn content (mass%), parameter Q represented by "Q=[Si]+2[Al]-[Mn]" is 2.00 or higher. The total mass of S included in sulfides and oxysulfides of Mg, Ca, Sr, Ba, Ce, La, Nd, Pr, Zn, and Cd is at least 40% of the total mass of S included in the non-oriented electromagnetic steel sheet. The {100} crystal orientation intensity is 3.0 or higher. The thickness is 0.15-0.30 mm. The average crystal grain size is 65-100 µm.
