Abstract

1. Способ производства листов из низколегированной хромосодержащей стали, включающий нагрев слябов под прокатку до температуры 1200-1260°С, многопроходную горячую прокатку в регламентируемом температурном диапазоне, отличающийся тем, что многопроходную прокатку завершают при температуре 800-920°С, после чего листы охлаждают водой до температуры 450-600°С, а затем завершают охлаждение листов на воздухе.2. Способ по п.1, отличающийся тем, что в процессе охлаждения листов водой их подвергают правке знакопеременным изгибом.1. A method of manufacturing sheets of low-alloy chromium-containing steel, including heating slabs for rolling to a temperature of 1200-1260 ° C, multi-pass hot rolling in a regulated temperature range, characterized in that multi-pass rolling is completed at a temperature of 800-920 ° C, after which the sheets are cooled water to a temperature of 450-600 ° C, and then complete cooling of the sheets in air. 2. The method according to claim 1, characterized in that in the process of cooling the sheets with water, they are subjected to editing by alternating bending.
