METHOD OF CHECKING FORSTERITE, APPARATUS THAT EVALUATES FORSTERITE, AND PRODUCTION LINE THAT MANUFACTURES STEEL SHEET |
摘要 |
The location where forsterite is present is checked in a region from which light excited by an electron beam is emitted when a material containing forsterite is irradiated with an electron beam. The material is preferably a grain oriented electrical steel sheet having a forsterite layer. In addition, it is preferable that the accelerating voltage be 10 kV or more when an electron beam is radiated when the material is a grain oriented electrical steel sheet having a tension coating layer on the forsterite layer. |
