Claims (1)

Способ производства изотропной электротехнической стали, включающий выплавку, горячую прокатку, травление, холодную прокатку, обезуглероживающе-рекристаллизационный отжиг, отличающийся тем, что горячекатаный металл не подвергается промежуточной термической обработке, а температура окончательного рекристаллизационного отжига после холодной прокатки определяется с учетом содержания кремния и фосфора из соотношения
t = 500 + 172,7[Si,%] - 276[Р,%] ± 10°C
при изменении содержания кремния в пределах 2,7 - 3,2% и фосфора 0,03 - 0,08 %.A method of producing isotropic electrical steel, including smelting, hot rolling, pickling, cold rolling, decarburization-recrystallization annealing, characterized in that the hot-rolled metal is not subjected to intermediate heat treatment, and the temperature of the final recrystallization annealing after cold rolling is determined taking into account the content of silicon and phosphorus from the ratio
t = 500 + 172.7 [Si,%] - 276 [P,%] ± 10 ° C
when changing the silicon content in the range of 2.7 - 3.2% and phosphorus 0.03 - 0.08%.
