GRAIN-ORIENTED ELECTROMAGNETIC STEEL SHEET |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a grain-oriented electromagnetic steel sheet having excellent noise-suppressing property to suppress noise low when building up a raw material having a formed groove for magnetic domain fractionation to an actual transformer. <P>SOLUTION: In the grain-oriented electromagnetic steel sheet having the groove for magnetic domain fractionation on either one of both sides of the steel sheet and having a forsterite film and a tension coating on both sides of the steel sheet, the deposit amounts A and B are controlled within a prescribed range when the deposit amount of the tension coating on the face having the groove is defined as A (g/m<SP POS="POST">2</SP>) and that on the face having no groove as B (g/m<SP POS="POST">2</SP>). <P>COPYRIGHT: (C)2012,JPO&INPIT |
