Description
(54) СПОСОБ ПОЛУЧЕНИЯ ЛИСТОВОГО МЕТАЛЛА КРЕМНИЙ-ЖЕЛЕЗО вл йт декарбюриэацию с последующим отжигом дл создани условий вторич ной рекристаллизации и получени ориентированной структуры за счет поглощени разориентированных зерен что обеспечиваетс первоначальной гор чей прокаткой со степенью дефор мации 5% при температуре интенсивного рЬста зерен с предварительным нагревом до высокой температуры. Обычно интенсивный рост зерен сл бон начинаетс при 12бО-1350°С. Однако первоначальное обжатие провод т при 750-1250С, причем наиболее предпочтительным вл етс интервал 850-И5рс. При первоначальном обжатии осуществл етс уменьщёние ра змера зерен сл ба после нагрева до 1400С; гор чее обжатие на 25% Приводит к получению зерен диаметро около 5 мм (предпочтительное обжати 10-50%). Пример. Шихту состава, вес углерод 0,034; марганец 0,06; сера 0,024 г кремний 3,17; железо-осталь расплавл ют по обычной технологии ;-в мартеновской или электродуговой печи, расплав заливают в ковш, куда ввод т необходимое количество кремни , после чего можно проводить рафинирование расплава с помощью вакуумного переплава. Затем расплав передают на разливку, где получают сл б толщиной 15 или 20 см. Далее провод т резку на сл бы определенной длины, нагрев до 1035°С, деформирование со степенью 25% др толщины 15 см, нагрев до 14., гор чую прокатку до толщины Г,9 мм, отжиг при , холоднуюпрокатку до толщины 0,264 мм две стадии с промежуточнумотжигом; при 925° С), декарбюризайию-отжиг при 825°С в атмосфере влажногр водорода и отжиг в контейнере при 1200с в течение 24 ч в атмосфере сухого водррода. В таблице приведены магнитные свойства и размер зерна в зависимости от содержани кремни , температуры нагрева сл бов и начальной деформацией при гор чей прокатке по предлагаемому способу.
