л  15 с подключением 16 дл  воздуха и отверсти ми дл  воздуха 17. Все охлаждающее устройство закреплено на фундаменте при помощи опор 18. Струйное сопло 12, ввинченное в насадку 19 струйной трубы 10, состоит из резьбового соединени  20, в котором размещен с возможностью вращени  нержавеющий шар 21 с центральным отверстием 22 (фиг.6).l 15 with a connection 16 for air and air holes 17. The entire cooling device is fixed to the foundation using supports 18. The jet nozzle 12 screwed into the nozzle 19 of the jet pipe 10 consists of a threaded connection 20, in which the stainless ball 21 with a Central hole 22 (Fig.6).

Устройство работает следующим образом .The device operates as follows.

Охлаждающа  вода под давлением преимущественно от 0,2 до 0,8 МПа попадает через воронку 6 в нижний резервуар дл  воды 4 и оттуда направл ютс  в верхний резервуар 5. Из резервуаров охлаждающа  вода течет через отверсти  9 в специальные клапаны. Из клапанов охлаждающа  вода через струйные трубы 10 и сопла 12 попадает на прокатываемый материал 23, причем охлаждающую воду выпускают через круглое отверстие шаров 21 т.е. преимущественно в виде круглой струи. После освобождени  зажима 11 и ослаблени  фиксатора 24 от прокручивани  струйные трубы 10 могут производить поворот, благодар  чему струю воды можно оптимально направл ть на прокатываемый материал 23, который (фиг.2) перемещаетс  слева направо через охлаждающее устройство. Чтобы в нижней части корпуса или в верхней части корпуса избежать подпора воды, имеетс  достаточное количество сливных отверстий 14, наход щихс  между истирающимис  планками 13. Дл  сборки охлаждающего устройства и прежде всего дл  быстрого демонтажа верхних частей в случае неисправности используют предпочтительно клинь  3. Чтобы освободить прокатанный материал от наход щейс  на нем воды, на него направл ют сжатый воздух через отверсти  17 сопла 15, причем со всех сто0Cooling water under pressure, preferably from 0.2 to 0.8 MPa, flows through a funnel 6 into the lower water tank 4 and from there is directed to the upper tank 5. From the tanks, the cooling water flows through openings 9 into special valves. From the valves, cooling water through the jet pipes 10 and nozzles 12 enters the rolling material 23, and cooling water is discharged through the round opening of the balls 21 i.e. mainly in the form of a round jet. After releasing the clamp 11 and loosening the latch 24 from rolling, the jet pipes 10 can rotate, whereby the stream of water can be optimally directed to the rolling material 23, which (Fig. 2) moves from left to right through the cooling device. In order to avoid water backwater in the lower part of the casing or in the upper part of the casing, there are a sufficient number of drain holes 14 located between the abrasion bars 13. For assembling the cooling device, and especially for quick dismantling of the upper parts in case of a malfunction, preferably use a wedge 3. To release rolled material from the water located on it, compressed air is directed to it through the holes 17 of the nozzle 15, and from all
