FIELD: metallurgy.
SUBSTANCE: method of producing an electrical steel sheet with an oriented structure includes grinding treatment of a magnetic domain structure by irradiation with an electron beam, performed in a vacuum chamber of low pressure, surface of sheet subjected to final annealing, at that, prior to irradiation, prior to irradiation with electron beam of electrical steel sheet coiled into a roll, its heating to 50 °C or higher, and then sheet cooling so that during entry into low-pressure vacuum chamber sheet has temperature below 50 °C.
EFFECT: reducing fluctuations of value of loss factor in iron of materials and stable production of good properties of losses in iron.
