Abstract

FIELD: metallurgy, in particular, production of corrugated texture steel. SUBSTANCE: method involves performing hot and cold rolling; effectuating normalizing decarburizing high-temperature annealing. According to aluminum content in steel, additional annealing in atmosphere is conducted upon hot or cold rolling. Nitrogen/hydrogen ratio in atmosphere is maintained in accordance with dependence:= 5.26 - 125 Al, where Al is aluminum content, %. EFFECT: increased quality of steel by improved magnetic properties.

Способ относится к металлургии и может применяться для производства стали с ребровой текстурой. Для улучшения магнитных свойств стали в способе, включающем горячую и холодную прокатку, нормализационный, обезуглероживающий и высокотемпературный отжиг, после горячей или холодной прокатки предусмотрен дополнительный отжиг в атмосфере, учитывающей содержание в стали AI,%, причем отношение N2/H2 в атмосфере отжига поддерживают по зависимости N2/H2 = 5,26 - 125 AI, где AI -содержание элемента в %.The method relates to metallurgy and can be used for the production of steel with a rib texture. To improve the magnetic properties of steel in a method including hot and cold rolling, normalization, decarburization and high-temperature annealing, after hot or cold rolling an additional annealing is provided in the atmosphere, taking into account the content of AI in steel,%, and the ratio N 2 / H 2 in the annealing atmosphere support according to the dependence N 2 / H 2 = 5.26 - 125 AI, where AI is the element content in%.
