Grain-oriented electrical steel sheet

This grain-oriented electrical steel sheet does not have a forsterite film present between a base steel sheet and a tension-insulation coating, in which the base steel sheet contains a predetermined element in a predetermined amount, and in a case in which a cross section perpendicular to a rolling...

Beschreibung
Zusammenfassung:	This grain-oriented electrical steel sheet does not have a forsterite film present between a base steel sheet and a tension-insulation coating, in which the base steel sheet contains a predetermined element in a predetermined amount, and in a case in which a cross section perpendicular to a rolling direction of the base steel sheet is viewed, when a region having a length of 10 μm from a surface of the base steel sheet toward the inside of the base steel sheet in a sheet thickness direction of the base steel sheet and a length of 20 mm in a direction perpendicular to the sheet thickness direction is an observation region, needle-like inclusions having a length of 1 μm or more are not present in the observation region.
