Изобретение относитс к листопрокатному производству и может быть использовано при прокатке полос на одно- или многоклетьевых станах, оборудованных нат жными устройствами.5The invention relates to sheet-rolling production and can be used when rolling strips on single- or multi-stand mills equipped with tensioning devices.
Известен способ регулировани распределени нат жени по ширине полосы приложением к ней силового воздействи , измен ющего нат жение по кромкам 1.There is a method of controlling the distribution of tension across the width of a strip by applying to it a force action that changes the tension along the edges 1.
Недостатком известного способа вл етс 10 то, что при существенных изменени х нат жени валки измерительного и регулирующего устройства оставл ют на полосе поверхностные дефекты, что снижает качество готовой продукции.15The disadvantage of this method is 10 that with significant changes in tension, the rolls of the measuring and regulating device leave surface defects on the strip, which reduces the quality of the finished product.
Целью изобретени вл етс повыщение качества прокатываемых полос.The aim of the invention is to increase the quality of the rolled strips.
Описываемый способ регулировани распределени нат жени по щирине полости отличаетс тем, что регулирование на- 20 т жени производ т путем скручивани полосы в плоскости, перпендикул рной оси прокатки.The described method of controlling the tension distribution across the width of the cavity is characterized in that the adjustment of the tension of 20 tons is performed by twisting the strip in a plane perpendicular to the axis of rolling.
На фиг. 1 показано положение поворотной обоймы с валками в момент настройки 25 стана; на фиг. 2 - то же, при по влении волнистости.FIG. 1 shows the position of the rotary cage with rolls at the time of setting 25 of the mill; in fig. 2 - the same, with the appearance of waviness.
Полосу 1, выщедщую из прокатного стана , пропускают через пару валков 2 (холостых или приводных), наход щихс в по- ЗЭThe strip 1, extruded from the rolling mill, is passed through a pair of rolls 2 (idle or driven) located in the EZ
воротной обойме 3, котора может поворачиватьс относительно оси прокатки. Зазор между валками устанавливают так, чтобы обеспечить небольщое обжатие полосы (в пределах упругих деформаций). При настройке стана поворотную обойму устанавливают под определенным углом а к плоскости прокатки (фиг. I), причем стан настраивают так, что нат жение на кромках и в середине полосы одинаково. Например , создают принудительный изгиб рабочих валков стана дл больщого обжати кромок полосы. Во врем прокатки угол поворота обоймы при по влении коробоватости увеличивают, обеспечива тем самым повыщение нат жени на кромках полосы, и при по влении волнистости-уменьшают (фиг. 2), обеспечива тем самым уменьшение нат жени кромок. Таким образом осуществл етс плавное регулирование нат жени по щирине полосы в процессе ее прокатки.gate case 3, which can rotate relative to the rolling axis. The gap between the rollers is set so as to ensure a slight compression of the strip (within the elastic deformations). When adjusting the mill, the swiveling yoke is set at a certain angle a to the rolling plane (Fig. I), and the mill is adjusted so that the tension on the edges and in the middle of the strip is the same. For example, create a forced bending of the work rolls of the mill for a large reduction of the edges of the strip. During rolling, the angle of rotation of the cage increases with the occurrence of warping, thereby increasing the tension on the edges of the strip, and with the appearance of waviness decreases (Fig. 2), thereby reducing the tension of the edges. Thus, smooth tension control is performed along the width of the strip during its rolling.
