METHOD OF MAKING SHEET OF TEXTURED ELECTRICAL STEEL Russian patent published in 2016 - IPC C21D8/12 H01F1/16 C22C38/02 C22C38/40 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy. To produce a sheet of textured electrical steel with stable low losses of iron manufacturing method contains hot rolling of steel slab containing wt%: C 0.001-0.10, Si 1.0-5.0, Mn 0.01-0.5, Al less than t 0.0100, each of the S, Se, O and N not more than 0.0050, Fe and the rest is unavoidable impurities. Single, double or multiple cold rolling of produced hot-rolled sheet, if necessary, intermediate annealing between them to final thickness, primary recrystallization annealing of the obtained cold-rolled sheet, application of annealing separator and final annealing, upon that in the area of 550-700°C during heating of primary recrystallization annealing one performs fast heating at mean rate of heating 40-200 °C/s, and in any area of temperatures from 250 to 550 °C heating rate is not more than 10 °C/c for 1-10 seconds.

EFFECT: production of texturized electrochemical steel.
