SHEET OF GRAIN-ORIENTED ELECTRIC STEEL, GRAIN-ORIENTED ELECTRIC STEEL WITH IMPROVED PROPERTIES OF LOSSES IN CORE Russian patent published in 2010 - IPC C21D8/12 H01F1/16 C22C38/60 

FIELD: metallurgy.

SUBSTANCE: for increasing of magnetic characteristics there is received sheet from steel, containing from 0.8 up to 7 wt % Si and allowing secondary recrystallized texture from orientation {110}<001> in the capacity of main orientation, herewith middle deviation angles α, β and γ from ideal orientation {110}<001> of the secondary recrystallised texture satisfying formula (α²+β²)^1/2≤γ, where α-middle deviation angle from ideal orientation {110}<001> around direction of normal (ND) to rolling surface of the secondary recrystallised texture, β- middle deviation angle from ideal orientation {110}<001> around transverse direction (TD) secondary recrystallised texture and γ: middle deviation angle from ideal orientation {110}<001> around rolling direction (RD) of the secondary recrystallised texture.

EFFECT: improved losses properties in core.
