METHOD FOR PLATE MANUFACTURE FROM NON-TEXTURED ELECTRICAL STEEL Russian patent published in 2014 - IPC C21D8/12 C21D9/46 H01F1/16 C22C38/02 

FIELD: metallurgy.

SUBSTANCE: invention involves hot rolling of initial material from steel containing the following, wt %: C not more than 0.03, Si not more than 4, Mn 0.03-3, Al not more than 3, S not more than 0.005, N not more than 0.005 and Fe and inevitable impurities are the rest; annealing in a hot zone; cold rolling and final annealing; size of a crystalline grain before cold rolling is brought to not more than 100 mcm, and final annealing is performed by quick heating to the temperature exceeding recrystallisation temperature at an average rate of temperature rise of at least 100°C/s.

EFFECT: obtaining plate from non-textured electrical steel with high density of a magnetic flux in a rolling direction.
