Also controlled by the sensing devices are roll heating and cooling means (Fig. 2, not shown). Spaced heating coils 30, 32 and 34, and fluid nozzles 36, 38, and 40 control the temperature and hence the profile of the rolls.

Изобретение относится к способу и устройству для прокатки полос металла в горячепронатном полосовом стане или в реверсивной клети. Стан горячей прокатки имеет по меньшей мере две прокатные клети с горизонтально настраиваемыми верхним и нижним рабочими валками. Каждый из валков непосредственно или через промежуточный валок опирается на опорный валок. В процессе деформации осуществляют регулирование состояния прокатываемой полосы. На полосу воздействуют двумя группами исполнительных органов, профилирующих и придающих полосе плоскостность. Задают целевой контур профиля полосы. Для достижения целевого контура исполнительные органы первой группы вводят в действие при толщинах прокатываемой полосы, превышающих критическую в отношении изменения области течения металла толщину. Исполнительные органы первой группы воздействуют, главным образом, на контур полосы в ее средней области. Исполнительные органы второй группы вводят в действие при толщинах полосы, меньше указанной критической толщины.

Preheating and thermal control of working rolls in metal rolling processes and their control system

FIELD: physics.SUBSTANCE: invention relates to use of hot aerosols 118 for preheating over the entire width of rolling mills 100 before processing a metal sheet or plate. Hot aerosols 118 can be controlled individually. Use of hot aerosols can allow rolling mill 100 to reach operating temperature and achieve desired heat bulge, so that metal sheet or plate 102 can be processed immediately with observance of tolerances on accuracy of flatness and size. Systems of hot aerosols 118 can be also equipped with existing systems of cooling liquids for creation of systems of thermal control of rolling mills 100 with bidirectional temperature control.EFFECT: invention provides the possibility of eliminating the need for a transient period of heating working rolls in the rolling mill operation to reduce the amount of scrap material and reduce time losses.32 cl, 8 dwg РОССИЙСКАЯ ФЕДЕРАЦИЯ (19) RU (11) (13) 2 705 045 C2 (51) МПК B21B 37/32 (2006.01) ФЕДЕРАЛЬНАЯ СЛУЖБА ПО ИНТЕЛЛЕКТУАЛЬНОЙ СОБСТВЕННОСТИ (12) ОПИСАНИЕ ИЗОБРЕТЕНИЯ К ПАТЕНТУ (52) СПК B21B 37/32 (2019.02) (21)(22) Заявка: 2018110545, 21.09.2016 (24) Дата начала отсчета срока действия патента: Дата регистрации: 01.11.2019 21.09.2015 US 62/221,491 (43) Дата публикации заявки: 23.10.2019 Бюл. № 30 (45) Опубликовано: 01.11.2019 Бюл. № 31 (56) Список документов, цитированных в отчете о поиске: US 2011005285 A, 13.01.2011.
