GRAIN-ORIENTED MAGNETIC STEEL SHEET |
摘要 |
Provided is a grain oriented electrical steel sheet having excellent noise property capable of suppressing noise of an actual transformer which is configured by a steel sheet material having grooves formed therein for magnetic domain refining. In a grain oriented electrical steel sheet having grooves on one surface of the steel sheet formed for magnetic domain refining, the steel sheet comprising a forsterite film and a tension coating on the front and back surfaces of the steel sheet, the tension coating is applied on a surface with the grooves in a coating amount A (g/m 2 ) and is applied on a surface with no groove in a coating amount B (g/m 2 ), the coating amounts A and B being restricted to fall within a predetermined range. |
