Abstract
1. Способ аустенитного проката изготовленной в процессе непрерывной отливки в установке непрерывного литья с толщиной отливки меньше 300 мм, предпочтительно с толщиной отливки меньше 150 мм черновой полосы, с помощью стадий уменьшения толщины, по меньшей мере, в одном, образованном из нескольких следующих друг за другом прокатных клетей прокатном стане, в горячекатаную полосу с толщиной проката между 0,5 и 15 мм и последующего поперечного разделения горячекатаной полосы в соответствии с величиной рулона, соответственно, длиной рулона перед намоткой в устройстве накопления, отличающийся тем, что толщину черновой полосы (6) уменьшают в каждом расположенном после установки непрерывного литья прокатном стане (W, W1, W2, W3) с количеством (n, n1, ni) стадий уменьшения толщины, при этом количество ni подлежащих выполнению стадий уменьшения толщины определяют из условия ! ! где TVB,i (°С) - усредненная по поперечному сечению температура черновой полосы в конце литейной машины (в зоне нижнего конца жидкой фазы в заготовке), соответственно, в конце установленного перед i-ым прокатным станом устройства промежуточного нагревания, ! Taust (°С) - зависящая от качества стали граничная температура образования аустенита (аустенитная конечная температура проката), ! hBr (мм) - толщина литья заготовки при сквозном затвердевании (в зоне нижнего конца жидкой фазы в заготовке), ! dend,i (мм) - толщина полосы после ni стадий уменьшения толщины i-го прокатного стана, ! mvor - количество всех выполненных после затвердевания заготовки стадий уменьшения толщины до входа в первую клеть последующего i-го прокатного стана, ! vg (м/мин) - скорость литья заготовки. ! 2. Спосо 1. The method of austenitic rolling produced in a continuous casting process in a continuous casting installation with a casting thickness of less than 300 mm, preferably with a casting thickness of less than 150 mm of the rough strip, using the steps of reducing the thickness of at least one formed from several successive another rolling mill stand, in a hot rolled strip with a thickness of between 0.5 and 15 mm and subsequent transverse separation of the hot rolled strip in accordance with the size of the roll, respectively, the length of the roll before skein in the accumulation device, characterized in that the thickness of the draft strip (6) is reduced in each rolling mill (W, W1, W2, W3) located after continuous casting with the number of (n, n1, ni) stages of thickness reduction, while the number The ni of the thickness reduction steps to be performed are determined from the condition! ! where TVB, i (° С) is the roughing temperature of the roughing strip at the end of the casting machine (in the area of the lower end of the liquid phase in the workpiece), respectively, at the end of the intermediate heating device installed in front of the i-th rolling mill,! Taust (° С) - boundary temperature of austenite formation depending on steel quality (austenitic final temperature of rolled products),! hBr (mm) - thickness of the casting of the workpiece during through hardening (in the zone of the lower end of the liquid phase in the workpiece),! dend, i (mm) - strip thickness after ni stages of reducing the thickness of the i-th rolling mill,! mvor - the number of all stages of thickness reduction performed after hardening of the workpiece before entering the first stand of the subsequent i-th rolling mill,! vg (m / min) - the casting speed of the workpiece. ! 2.
