Method of reducing iron loss of grain oriented silicon steel sheet. |
| 摘要 |
<p>The iron loss is reduced by irradiating plasma flame to the surface of the grain oriented silicon steel sheet, wherein the irradiation interval ( l ) of plasma flame is controlled so as to satisfy the following equation (1): 22 - 2.5D </= l </= 36 - 2.5D (1) (D is an average secondary recrystallized grain size of the steel sheet).</p> |
