Способ относится к металлургии и может применяться в производстве электротехнической стали из железокремнистых сплавов. Для улучшения магнитных свойств стали, повышения скорости и равномерности травления окалины, снижения расходного коэффициента на производство единицы продукции в способе, включающем горячую прокатку с температурой окончания чистовой прокатки (tк.п.) 1100 - 900°С и температурой смотки (tсм.) 700 - 600°С, травление окалины, холодную прокатку, рекристаллизационный, обезуглероживающий и высокотемпературный отжиг, охлаждение от tк.п. до tсм. ведут со скоростью 20 - 50°С/с.The method relates to metallurgy and can be used in the production of electrical steel from iron-silicon alloys. For improving the magnetic properties of the steel, improve the speed and uniformity of etching scale, reducing consumption coefficient per unit of production in the method comprising hot rolling with a temperature of the end of the finish rolling (t to n..) 1100 - 900 ° C and the coiling temperature (t s m . ) 700 - 600 ° С, etching of scale, cold rolling, recrystallization, decarburization and high-temperature annealing, cooling from t to . p . to t to m. lead with a speed of 20 - 50 ° C / s.
