FIELD: metallurgy.
SUBSTANCE: there is implemented steelmaking, hot rolling, two- or one-time cold rolling of strip, decarburising annealing of strip in intermediate or finite thickness, application of heat resistant coating, high-temperature and levelling annealing, herewith before application of heat resistant coating it is implemented etching of strips, and heat resistant coating contains magnesium oxide - MgO, silica - SiO2 and magnesium hydroxide - Mg(OH)2, at following ratio of components, in wt h: MgO - 100, Mg(OH)2 - (6-9), SiO2 - (0.1-0.5).
EFFECT: improvement of magnetic properties of steel and quality of coating.
