SHEET OF ELECTROTECHNICAL TEXTURED STEEL FOR IRON CORE AND METHOD OF ITS MANUFACTURING Russian patent published in 2016 - IPC C21D8/12 H01F1/16 C21D1/09 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy. To reduce power losses in transformers during operation it is obtained sheet of electrotechnical textured steel, with characteristics of losses in iron in the range of excitation from 1.5-1.9 tesla, in which in nearby areas of linear deformations is formed a residual voltage of 150 MPA or higher, wherein each such area extends to 300 µm or less in rolling direction and on 42 µm or more in sheet thickness direction, and the fields of linear deformations are periodically formed with intervals of 2 mm to 10 mm in rolling direction.

EFFECT: reduced power losses.
