METHOD OF MAKING PLATE OF TEXTURED ELECTRICAL STEEL Russian patent published in 2017 - IPC C21D8/12 C21D9/46 H01F1/16 C22C38/60 

FIELD: metallurgy.

SUBSTANCE: invention relates to metallurgy. To reduce losses in iron and provide small fluctuations of value of losses in iron method involves hot rolling of steel slab, containing, wt%: C 0.002–0.10, Si 2.0–8.0 and Mn 0.005–1.0, for producing hot-rolled sheet, if necessary annealing in hot zone conditions of hot-rolled steel sheet, single, or double, or repeated cold rolling with intermediate annealing between them for producing cold-rolled sheet of final thickness, primary recrystallization annealing in combination with carbon-removing annealing of cold-rolled sheet, application of annealing separator on surface of steel sheet and final annealing, fast heating is performed at rate of no less than 50 °C/s in range of 100–700 °C in process of heating of primary recrystallization annealing, steel plate is held at any temperature within 250–600 °C for 0.5–10 s 2–6 times.

EFFECT: reduced losses in iron.
