Description
ны 0,65 мм и подвергают рекристаллизационному отжигу. Затем провод т вторую холодную прокатку до конечной толщины 0,35 мм и обезуглероживающий отжиг.0.65 mm and subjected to recrystallization annealing. A second cold rolling is then carried out to a final thickness of 0.35 mm and a decarburization annealing.
Далее по предлагаемому способу ленту локально изгибают под углом 60° перпендикул рно к направлению прокатки на прокатном стане с валками, поперечное сечение которых имеет вид щестерни с щагом 2 мм, и отжигают в течение 1-3 мин при 830°С. Чтобы полоса была ровной, во врем отжига к ленте прикладывают раст гивающие усили . После этого следует высокотемпературный отжиг.Further, according to the proposed method, the tape is locally bent at an angle of 60 ° perpendicular to the rolling direction on a rolling mill with rollers, the cross section of which has the appearance of a pinion with schagom 2 mm, and is annealed for 1-3 minutes at 830 ° C. In order to make the strip even, tensile forces are applied to the tape during annealing. This is followed by high-temperature annealing.
Обработанна таким способом полоса имеет зерна щириной 2,5 мм, которые выт нуты поперек направлени прокатки. Контрольные образцы, на которых не проводили локальный изгиб с последующим отжигом, имеют равноосные зерна диаметром 7 мм.The strip treated in this way has grains with a width of 2.5 mm, which are drawn across the rolling direction. The control samples, on which no local bending was performed with subsequent annealing, have equiaxial grains with a diameter of 7 mm.
Таким образом, предлагаемый способ обработки железокремнистых сплавов позвоЛИТ регулировать размер и форму зерен при вторичной рекристаллизации. Способ прост в осуществлении, дает надежные результаты и пригоден дл производства стали по схеме с однократной холодной прокаткой.Thus, the proposed method of processing iron-silicon alloys will allow to adjust the size and shape of grains during secondary recrystallization. The method is simple to implement, gives reliable results and is suitable for steel production according to the single cold rolling scheme.
