FIELD: metallurgy.
SUBSTANCE: sheet of textured electrical steel with insulating coating creating tension on the sheet surface, which consists of a coating layer A formed on the surface of steel sheet and composed of oxide, and coating layer B, formed on the top surface and made of glass, at that the ratio R (σB/σA) of tension σB of layer coating B on the top surface, that is created on a steel sheet in the direction of rolling, to tension σA of layer coating A generated on surface of the steel sheet in the direction of rolling, is in the range 1.20-4.0.
EFFECT: production of sheet from textured electrotechnical steel with stable high magnetic properties and good adhesion of the coating.
