Description

Изобретение относитс  к прокатно му производству. Известен способ прокатки полосовой стали, в процессе которого две полосы накладывают одну на другую и подвергают их совместной деформации в последовательно установленных клет х непрерывного стана Ц. Недостатком известного способа  вл етс  повышенна  разнотолщинность прокатьшаемых полос. Цель изобретени  - повышение точности готового проката. Указанна  цель достигаетс  тем, что на выходе из последней клети непрерывного стана полосы раздваивают и каждую полосу прокатывают в той же клети между рабочими и опорными валками с огибанием каждой полосы вокруг соответствующего рабочего вал ка на 180 и рассогласованием скоростей вращени  рабочих и опорных валков , при этом в качестве ведомых вал ков этой клети используют рабочие валки. Это повышает точность готового проката. На чертеже изображен непрерывный прокатный стан во врем  прокатки пол совой стали. Прокатный стан состоит из рабочих клетей 1, 2 и 3 симметричной прокатки (на чертеже показаны три клети, но можно установить требуемое число клетей) и клетей 4 и 5 асимметричной прокатки дл  осуществлени  процесса прокатки-волочени  (ПВ). Рабочие валки 6 и 7 клети 3 (последней в приведенном случае) используютс  в качестве ведомых ПВ 4 и 5. В клет х 4 и 5 установлены рабочие валки 8, 9, которые используютс  в качестве ведущих валков. Перед прокаткой приготовленные полосы 10 и 11, смотанные в рулоны, накладывают одну на другую перед клетью 1. В процессе прокатки полосы (скорость V, показана на чертеже) подвергают деформации в последовательно расположенных клет х 1-3 стана. Дл  предотвращени  слипани  полос их раздел ют после каждого очага деформации .- На выходе из клети 3 полосы 10 и 11 раздваивают каждую, прокатывают с разньми окружными скорост ми рабочих валков 6 и 9 клети 4 (полоса 10) и 7 и 8 клети 5 (полоса 11). В процессе прокатки разнотолщинность полос 10 и 11 устран ют регулированием соотношени  окоужн1лхThis invention relates to rolling production. There is a known method of rolling strip steel, during which two strips overlap one another and subject them to joint deformation in successively installed cells of a continuous mill C. A disadvantage of the known method is the increased thickness variation of the rolled stripes. The purpose of the invention is to improve the accuracy of finished products. This goal is achieved by splitting the strip at the exit from the last stand of the continuous mill and each strip is rolled in the same stand between the working and support rolls, rounding each strip around the corresponding work roll by 180 and the rotation speeds of the work rolls and the support rolls are mismatched. Work rolls are used as driven rollers of this stand. This improves the accuracy of finished products. The drawing shows a continuous rolling mill during the rolling of steel. The rolling mill consists of symmetric rolling work stands 1, 2 and 3 (three stands are shown in the drawing, but the required number of stands can be set) and asymmetric rolling stands 4 and 5 for the rolling-drawing process (PV). The work rolls 6 and 7 of the stand 3 (the last in the above case) are used as slaves PV 4 and 5. The work rolls 8, 9 are installed in cages x 4 and 5, which are used as drive rollers. Before rolling, the prepared strips 10 and 11, which are wound up in rolls, are placed one on top of the other in front of the cage 1. During the rolling process, the strips (speed V, shown in the drawing) are subjected to deformation in successive stands 1-3 of the mill. To prevent sticking together, the strips are divided after each deformation zone. At the exit of the stand 3, the strips 10 and 11 are split in two, rolled with different circumferential speeds of the work rolls 6 and 9 of stand 4 (strip 10) and 7 and 8 of stand 5 (strip eleven). In the rolling process, the thickness variation of the strips 10 and 11 is eliminated by adjusting the ratio of co-lu
