FIELD: metallurgy.
SUBSTANCE: to improve quality of silicon steel sheet by excluding formation of dense oxides, method of producing sheet from normalised silicon steel includes steps of melting steel, hot rolling and normalisation. At step of normalisation furnace is used for normalising containing section of furnace for non-oxidative heating. Section of furnace for non-oxidative heating comprises more than 3 zones. Level of power supply of furnace zones used in section of furnace for non-oxidative heating, is set such that excess air factor α of section of furnace for non-oxidative heating falls in range of 0.8≤ α<1.0.
EFFECT: higher quality of silicon sheet steel.
