Abstract:
Grain-oriented electrical steel sheet superior in core loss characteristic containing Si: 0.8 to 7 mass% and having a secondary recrystallized texture with a {110} orientation as the main orientation, characterized in that average deviation angles α, β, and γ from the {110} ideal orientation of the secondary recrystallized texture satisfy (α 2 +β 2 ) 1/2 ≤γ, where α: average deviation angle from {110} ideal orientation around rolling surface normal direction (ND) of secondary recrystallized texture, β: average deviation angle from {110} ideal orientation around traverse direction (TD) of secondary recrystallized texture, and γ: average deviation angle from {110} ideal orientation around rolling direction (RD) of secondary recrystallized texture.
