Известны устройства дл нанесени смазки на валки при гор чей прокатке в услови х одновременной подачи охладител на валки, содержащие герметично прижатую к валку полую камеру с форсунками дл смазки «а поверхность валка.Devices for applying lubricant to rolls are known during hot rolling under conditions of simultaneous supply of a cooler to rolls containing a hollow chamber hermetically pressed against the roll with lubrication nozzles on the roll surface.
Цель изобретени - исключение попадани в камеру охладител и улучшение условий образовани равномерной смазочной пленки па поверхности валка.The purpose of the invention is to prevent the cooler from entering the chamber and to improve the conditions for the formation of a uniform lubricating film on the roll surface.
Дл этого внутри камеры по ее длине размещен р д сопел, направленных противоположно вращению валка и соединенных с магистралью сжатого воздуха.To do this, a series of nozzles are placed along the length of the chamber, opposite the rotation of the roll and connected to the compressed air line.
На чертеже изображено предложенное устройство .The drawing shows the proposed device.
Устройство состоит из камеры 1, герметично -прижатой к Поверхности валка 2 пружиной 3 с помощью ШарнирНО-укрепленного на арматуре 4 клети рычага 5. Внутри камеры установлены сопла 6 по всей ее длине, направленные противоположно вращению валка и соединенные щтуцером 7 с магистралью сжатого воздуха. Штифтова форсунка 8 крепитс к камере 1 таким образом, чтобы распыление смазки осуществл лось в полости камеры.The device consists of a chamber 1, hermetically pressed to the surface of the roll 2 by a spring 3 by means of a lever 5 pivotally fixed on the reinforcement 4 of the cage. Inside the chamber there are nozzles 6 along its entire length, directed opposite to the rotation of the roll and connected by means of a compressed air line 7. The pin nozzle 8 is attached to the chamber 1 so that the lubricant is sprayed in the cavity of the chamber.
Устройство работает следующим образом.The device works as follows.
Воздух, подведенный к соплам из магистрали с давлением 2-5 ати, вырываетс -через «еплотности в контакте камеры с поверхностью The air supplied to the nozzles from the line with a pressure of 2–5 MPa is pulled out through “density in contact of the chamber with the surface
22
валка и оттесн ет пленку воды, имеющуюс на металле, одновременно создава повыщенное давление (до 5 ати) в полости камеры, преп тству попаданию туда воды и уменьша износ кромок камеры, наход щихс в контакте с вал-ком. Регулировка расхода смазки и подача ее под давлением 80-130 ати к щтифтовым форсункам осуществл етс плунжерным насосом, шричем кажда форсунка соедин етс с отдельной плунжерной парой насоса . Повышенное давление воздуха в зоне нанесени смазки в ПОЛОСТИ камеры не преп тствует ее распылению.rolls and pushes back the water film on the metal, simultaneously creating an increased pressure (up to 5 atm) in the cavity of the chamber, preventing water from entering there and reducing the wear of the edges of the chamber in contact with the shaft. Adjusting the lubricant flow rate and supplying it under pressure of 80-130 bari to the puff nozzles is carried out by a plunger pump, each one is connected to a separate plunger pump pair. The increased air pressure in the zone of application of lubricant in the CAVITY of the chamber does not prevent its dispersion.
.Погонное усилие прижати камеры к поверхности валка пружиной 5 зависит от давлени воздуха в магистрали и размеров кожуха и составл ет 1-2 кгс/см.The pursuit force against the chamber against the roll surface by the spring 5 depends on the air pressure in the line and the dimensions of the casing and is 1-2 kgf / cm.
