FIELD: methods of inhibition control in manufacture of textured sheets of electric steel. SUBSTANCE: in manufacture of textured sheets of electric steel, inhibition of hot-rolled sheet is controlled by thorough balancing of content of copper, aluminum and carbon for determination after stage of strip hot rolling, type and quantity of separated secondary phases to obtain optimal sizes of grains in decarburizing annealing and to ensure subsequent high-temperature continuous heat treatment in which by means of nitrogen diffusion along strip layers, aluminum is directly precipitated in the form of nitride attaining in said manner quantity of secondary phases required for control of grain orientation in final product. EFFECT: higher magnetic properties of steel. 6 cl, 4 tbl, 4 ex
