Description
(.54) УСТРОЙСТВО ДЛЯ ОХЛАВДЕНИЯ ДВИЖУЩЕГОСЯ ПРОКАТА(.54) DEVICE FOR COOLING MOVING RENT
1one
Изобретение относитс к прокатному производству и может быть использовано дл ускоренного охлаждени изделий после прокатки,а также дл подстуживани раската в процессе прокатгки .The invention relates to rolling production and can be used to accelerate the cooling of products after rolling, as well as to accelerate the roll in the rolling process.
Известны устройства дл транспортировани и охлаждени проката, включа-. ющие транспортирующие ролики, межроликовые плиты, устройства дл верхнего и нижнего п-одвода хладагента и отверсти дл подачи хладагента через плиты J .Devices are known for transporting and cooling rolled products, including. transporting rollers, inter roller plates, devices for the upper and lower refrigerant supply and openings for supplying refrigerant through the plates J.
Недостатком известных устройств вл етс то, что в плитах рольганга изготавливаютс специальные отверсти дл подачи струй охладител к нижней поверхности проката. Вследствие застревани проката в отверсти х создаетс опасность бурежки полос при движении вдоль рольганга. Наличие окон в плитах снижает поверхность охлаждаемого раската и ограничивает количество действугопщх форсунок.A disadvantage of the known devices is that special openings for supplying coolant jets to the bottom surface of the car are made in the plates of the roll tables. Owing to the sticking of rolled metal in the holes, there is a danger that the strip will be wiped when moving along the roller table. The presence of windows in the plates reduces the surface of the cooled stock and limits the number of effective nozzles.
Наиболее близким к предлагаемому вл етс устройство дл охлаждени движущегос проката, включацощее коллектор с вод ными соплами, установленный между роликами отвод щего рольганга внутри накопительной камеры, на которой установлена крьшка с отверсти ми 2 .Closest to the present invention, there is a device for cooling a rolling stock, including an advanced collector with water nozzles, mounted between the rollers of the outgoing roller table inside the collection chamber, on which the cover with holes 2 is installed.
Недостатком данного устройства вл етс то, что размещение коллекто10 ров дл подачи охладител между роликами рольганга требует изготовл.ени в плитах отверстий дл подачи струй охладител на поверхность проката,что приводит к задержкам полосы на роль15 Ганге. Это снижает интенсивность охлаждени и увеличивает его неравномерность . Данное устройство не позвол ет увеличивать темп прокатки, а также способствует нестабильному положению The disadvantage of this device is that the placement of the collectors for supplying a cooler between the rollers of the live rolls requires making holes in the plates for supplying jets of cooler to the rolling surface, which leads to delays of the strip by role 15 Ganges. This reduces the cooling rate and increases its unevenness. This device does not allow to increase the rolling rate, and also contributes to the unstable position
20 полосы на поле рольганга.20 lanes on the roller table.
