Изобретение относитс к прокатному производству и может быть использовано, в частности , при холодной прокате полосовой стали.The invention relates to rolling production and can be used, in particular, in cold rolled strip steel.
Известны устройства дл подачи смазки к зоне деформации в прокатываемой полосе, включающие валки.Apparatus for supplying lubricant to a deformation zone in a rolled strip, including rolls, are known.
С целью создани высокого давлени смазки перед очагом деформации в предлагаедюм устройстве в зеве между валками и прокатываемой полосой размещены клиновидные вставки, оканчивающиес острыми, кромками со стороны входа полосы в валки и образующие с рабочими валками и полосой щелевые зазоры, в которые подаетс смазка. С целью упращен и конструкции вставки могут быть закреплены ва сегментных подушках, которые охватывают бочки валков.In order to create high pressure of the lubricant, wedge-shaped inserts are placed in the throat between the rollers and the rolled strip in front of the deformation zone, ending in sharp rolls forming from the inlet side of the rolls and forming gaps in the rolls and lubricant. In order to be simplified, the insert designs can be fixed on the segment cushions that cover the roll barrels.
Это обеспечивает подачу смазки к очагу деформации двум сход щимис потоками с нарастанием давлени смазки за счет нагиетани ее в щелевые зазоры вращающимис валка.ми и движущейс полосой. Поступление в очаг деформации смазки под высоким давлением обеспечивает при прокатке услови , близкие к услови м гидродинамического трени , что снижает усилие прокатки и уменьщает износ валков.This ensures that the lubricant is supplied to the deformation zone by two converging streams with an increase in the lubricant pressure due to its inflow into the gap gaps by rotating rollers and a moving strip. Admission to the deformation center of the lubricant under high pressure during rolling provides conditions close to the conditions of hydrodynamic friction, which reduces the rolling force and reduces the wear of the rolls.
На фиг. 1 -показано предлагаемое устройство , полеречный разрез; на фи,г. 2 - сече«ие по А-А на фиг. 1.FIG. 1 shows the proposed device, cross-section; on fi g. 2 - section along A-A in FIG. one.
Устройство содержит рабочие валки 1, подущки 2, прокатываемую полосу 3 и регулируемые дроссели 4, 5 6.The device contains work rolls 1, pods 2, rolled strip 3 and adjustable chokes 4, 5 6.
Подушки 2 имеют отверсти дл подвода смазки к паза.м (карманаа1-цакопител м смазки ) 7-10. В зеве валков со стороны входа полосы в валки с.менные вставки // (из антифрикционного материала или с антифрикционным покрытием) подущек оканчиваютс заостренными кромками.The pillows 2 have holes for supplying lubricant to the groove. (Pocket-1-accumulator lubricant) 7-10. In the shed of the rolls, on the side of the entrance of the strip to the rolls, the replaceable inserts // (of antifriction material or with an anti-friction coating) of the underlays end in pointed edges.
Со стороны выхода полосы из валков аналогичные вставки оканчиваютс затупленными кромками.On the exit side of the strip of rolls, similar inserts end with blunted edges.
Подача смазки к очагу деформации посредством предлагаемого устройства осуществл етс следующем образом.The lubricant is supplied to the deformation zone by means of the proposed device as follows.
Под некоторым малым напором смазка поступает из обшей магистрали в пазы 7 и 8. Давление смазки в этих пазах меньше, чем в общей магистрали, и регулируетс дросселем 5. При вращении валков / и движевии полосы 3 в направлении прокатки смазка увлекаетс полосой и валками в щелевые зазоры между вставкой и полосой, и вставкой и валками. Эффект нагнетани смазки в очат деформации создает подпор гидростатического давлени , постепенно увеличивающегос ко входу в очаг деформации.Under some small pressure, the lubricant comes from the common pipe to the grooves 7 and 8. The lubricant pressure in these grooves is less than the common line, and is regulated by the throttle 5. When the rollers / are rotated and the strip 3 moves in the direction of rolling, the lubricant moves the strip and the rollers into the slotted the gaps between the insert and the strip, and the insert and rolls. The effect of injecting lubricant into the deformation region creates a hydrostatic pressure back-up, gradually increasing to the entrance to the deformation zone.
Регулирование давлени смазки в очаге деформации осуществл етс при помощи дросселей 5 н 6. Дросселем 4 регулируетс вертикальное усилие, отжимающее валки от иодушек ..The lubrication pressure in the deformation zone is controlled by means of 5 n 6 chokes. Throttle 4 regulates the vertical force that pushes the rollers from the idler.
