description	FIELD: metallurgy.SUBSTANCE: invention relates to metallurgy, namely to electrical steel sheet with oriented grain structure used as material of transformer cores. Sheet has a chemical composition containing the following in wt%: Si: from 1.8 to 7.0, Cu: from 0.03 to 0.60, balance - Fe and impurities. On the surface of steel sheet there is a film of primary coating containing forsterite, at that, ratio of Cu/Fe radiation intensity in interface between primary coating film and steel sheet surface makes 0.30 or less. Sheet has high magnetic properties and high adhesion between film of primary coating and steel sheet.EFFECT: electrotechnical steel sheet with oriented grain structure and decarbonized steel sheet used for its production are proposed.5 cl, 3 dwg, 6 tbl, 1 ex Изобретение относится к области металлургии, а именно к электротехническому стальному листу с ориентированной зеренной структурой, используемому в качестве материала сердечников трансформаторов. Лист имеет химический состав, содержащий, мас.%: Si: от 1,8 до 7,0, Cu: от 0,03 до 0,60, остальное - Fe и примеси. На поверхности стального листа имеется пленка первичного покрытия, содержащего форстерит, при этом отношение интенсивности светоизлучения Cu/Fe в области раздела между пленкой первичного покрытия и поверхностью стального листа составляет 0,30 или меньше. Лист имеет высокие магнитные свойства и высокую адгезию между пленкой первичного покрытия и стальным листом. 2 н. и 3 з.п. ф-лы, 3 ил., 6 табл., 1 пр.
