Abstract RU 2675887 C1

FIELD: technological processes.

SUBSTANCE: invention relates to the coated with the insulating coating textured electrical sheet steel and its manufacturing method. Textured electrical sheet steel with the insulating coating contains located on the textured electrical steel sheet surface insulating coating, which contains at least one chemical element, selected from the group consisting of Mg, Ca, Ba, Sr, Zn, Al and Mn, and also Si, P and O.

EFFECT: wherein the insulating coating has the X-ray absorption fine structure spectrum (FSRAS) for the K-absorption band border P with three absorption peaks in the range from 2,156 eV to 2,180 eV, and is characterized by excellent heat resistance.
