FIELD: metallurgy.
SUBSTANCE: invention refers to metallurgy and production of texturised electric steel sheet. To improve magnetic properties, the sheet is heated at 1350°C or lower temperature, where (a) hot-rolled sheet is heated to given temperature of 1000 to 1150°C and annealed after recrystallisation for required time period at lower temperature of 850 to 1150°C; or (b) decarburisation is performed during annealing of hot-rolled sheet so as to gain 0.002-0.02 wt % difference in carbon amount before and after decarburisation. During temperature increase at the stage of decarburisation annealing of steel sheet, heating is performed within 550-720°C temperature range at heating rate of at least 40°C/second, preferrably 75-125°C/second, applying induction heating for fast heating used during temperature increase at decarburisation annealing stage.
EFFECT: method of texturised electric steel sheet production.
