METHOD OF MAKING TEXTURED ELECTRICAL STEEL SHEET WITH LOW LOSSES IN IRON Russian patent published in 2016 - IPC C21D8/12 C21D1/09 H01F1/16 

FIELD: metal processing.

SUBSTANCE: invention relates to production of sheet from textured electrical steel. To increase efficiency sheet manufacturing process sheet with thickness t surface is irradiated by electron beam in direction intersecting rolling direction, and irradiation energy E(t) is adjusted when meeting following ratio: Ewmin (0.23) x (1.61 - 2.83 x t (mm)) ≤ E(t) ≤ Ewmin (0.23) x (1.78 - 3.12 x t (mm)), where Ewmin (0.23) is radiation energy, at which losses in iron for material with sheet thickness t 0.23 mm are minimum.

EFFECT: higher process efficiency.
