SHEET FROM TEXTURED ELECTRIC STEEL Russian patent published in 2015 - IPC C21D8/12 H01F1/16 C23C22/00 

FIELD: metallurgy.

SUBSTANCE: invention relates to a sheet from textured electric steel. For suppression of noise of real transformer, which is designed from steel sheet with grooves, made for grinding of magnetic domains, the sheet from textured electric steel with grooves on one of the surfaces for grinding of magnetic domains, has a forsterite film and tension forming coating on the steel sheet surface with grooves and without grooves is applied, and the tension forming coating is applied on the surface with grooves, in amount A (g/m²) and on the surface without grooves - in amount B (g/m²), and the amount of coatings A and B are limited by falling within the pre-determined range.

EFFECT: noise suppression.
