Grain-oriented silicon steel sheet and process for producing the same |
| 摘要 |
Extremely low watt-loss of W17/50</=0.88 w/kg is provided by the combination of extremely low carbon, silicon and nitrogen contents; a thin sheet thickness of 0.15 to 0.23 mm; a high magnetic flux density B10>/=1.89 T; and copresence of coarse and fine (2 mm or less) grains, the distance ( &upbar& N) between the fine grains controlled to 2.0 to 8.0 mm.
