    The invention relates to a device for cooling by immersing hot metal pipes, such devices may, for example, enter the pipe manufacturing cycle either immediately after the hot upsetting of the pipe, or be used for special heat treatment, for example quenching.
    The manufacture of metal pipes, in particular steel pipes, requires forming, heat treatment and finishing operations. .
    The cooling device can be used as. quenching system lnbo at the exit of the heating furnace, or at the exit of the installation of hot pipe stamping, for example a press for squeezing through a glass point, as well as for processing thin pipes with a large ratio of external diameter to thickness — usually more than 20, and a long length, of the order 10-20 m.
    The purpose of the invention is to increase the uniformity of cooling of pipes by symmetrically circulating cooling fluid around the pipe during the process of lowering it into the tank.
    FIG. 1 shows a cooling device, top view; FIG. 2 shows section A-A in FIG. 1, in FIG. 3 is a sectional view of FIG. 1, FIG. 4 shows a section B-B in FIG. 3, in FIG. 5-8 - reflectors mounted on the immersion of the pipe; variants, in FIG. 9 - quenching device, cut.
    The device for rapid cooling contains a conveyor t, equipped with rollers 2, along which the pipe 3 to be processed (100 mm in diameter) moves. The tank 4 is made open, parallel to the transporter and is formed by a block in the form of a parallelepiped of sheet material and is installed on the base 5. The tank is made with level 6 of coolant. The coolant temperature is kept close to the ambient temperature. A plurality of side pipes 7 for supplying water is distributed along the entire length of the tank and is powered by a common pipeline. Discharge of fluid from the tank, allowing the level to remain constant, is not shown.
    The side transfer device, the immersion conveyor-system and the immersion system are formed by seven levers 9 with two arms 10 and 11, which are evenly distributed along the entire length of the tank. The arms of the arms provide lifting and laying of the conveyor pipe, and the arms 11 form the immersion device. The levers 9 are mounted on a common shaft 12 rotating in a variety of bearings 13 mounted on rails 14 between the conveyor and the tank. 3 The levers are mounted aligned in a row on the shaft 12 so that the pipe sinks horizontally. They are simultaneously set in motion by a jack 15 wedged in two extreme positions corresponding to the positions of the Transporter for the shoulder 10 and the Dive for the shoulder 11. The shoulders 10 have roundings 16 and manipulate the pipe through their inner corner 17. The square 18 is fixed on shoulders 11 in the space located below and to the right of the pipe, and near it, when the pipe goes to the level of the liquid. This coal nickname runs along the entire length of the tank from the first to the last lever. The air nozzle 19 is attached to the end of the pipe. The entire system is mounted on a special lever 20 mounted on a common shaft 12 and subject to the same movements as the levers 9. The lever 20 has an internal angle 21 similar to the angles 17 on which the pipe rests. Air Nozzle 19 is mounted on the flange, forming a connection with the end 23 from the side of the pipe stickings. This flange is located on the lever 24, which rotates around an axis 25 rigidly connected to the lever 20. The flange 22 is continuously pushed to the end 23 of the pipe, which is an open section and is pre-installed longitudinally by means of a rod 26 moved by a spring 27, moreover, to the rod has not come out of its internal opening; an emphasis is provided. However, this movement of the flange to the pipe is compensated for by the oncoming movement caused by the cam 28 acting on the idle cylindrical block 29 mounted on the swing arm 24. The cam mounted on the shaft 30 rotating around two bearings 31 and 32 fixed on the arm is driven during rotation when lowering this lever to immerse the pipe by means of a system of two bevel gears, one of which is fixed and the second is mounted on the cam shaft 30. The cam profile is such that the flange 22 is pressed to the end of the pipe 3 and in the submerged position, with ET. The nozzle 19 enters the pipe 3 separated from the pipe end in a high 94 position before or after immersion, while the front end of the air nozzle 19 is separated from the pipe and admits its lateral transfer. The air nozzle 19 is mounted on the flange 22 by means of a threaded joint so as to adapt the diameter of the nozzle to the internal diameter of the pipe being processed. The diameter of the nozzle is usually such that the ratio of the internal section of the pipe to the section of the nozzle 19 is about three. Compressed air obtained from a standard compressed air network with a pressure of 5 bar is supplied to the nozzle using a flexible pipe (not shown). ; Angle 18 - (fig. 5) can be formed from two parts, one fixed, fixed by welding on the lever 11, and two adjustable shelves 33 and 34. The opening width at the end of the square is adjusted by sliding the thread-bolts group 35 into the groove 36 shelves 33 and 34. The square 18 depicted in FIG. 7, has certain dimensions, is attached to the lever 9 by a group of a threaded rod-bolts 37, slidable in a vertical slot 38, located to the bottom right of the angle 17 in the shoulder of the lever 11. The squares are fixed — pairwise on one side and on the other side of the shoulder 11. Adjustment Carbonics 18 are needed to balance the circulation of water when the pipes are lowered to the immersion position. The cooling device operates as follows. The hot pipe is taken out of the furnace and longitudinally placed on the conveyor 1. The shoulders 10 of the levers 9 capture the pipe 3 at the rounding 16 (the dotted line in FIG. 2). The first rotation of the levers 9 brings the linear part 39 of the shoulder 11 into a horizontal position, slightly inclined to level 6, and maintains the lever in that position. The pipe is thus moved from one position to another by twisting without sliding on the straight part 39. The system is designed in such a way that the immersion device formed by the arm 11 and the angle 17 is not submerged when the tube moves from one position to another, while the straight line part 39 of a substantial degree
    horizontal. At this level, the front end of the air nozzle 19 is substantially distant so as not to interfere with the free passage of the end of the tube 3. Then the tube is seized with a jack acting on the movable lever 9.
    The levers 9 continue to rotate in the direction of arrow F, and at the same time air is injected into the pipe 3. The pipe quickly sinks due to the continued rotation of the levers 9. During the rotation of the levers 9 due to the operation of the cam 28 and the rod 26, the supporting nozzle flange 22 adjoins the end of the pipe with a free edge, pipe passes are mostly air. The tube 3 is then left shrunk for the time needed to cool it to the desired temperature. The pipe is then raised by turning the levers 9 in the return stroke. The air is blown into the pipe before the horizontal section of the rectilinear part 39 goes over, which allows water to be removed from the pipe that could penetrate inside the pipe. Continuing the reverse rotation of the levers 9 converts the pipe from the angle 17 to the rounding 16. Then the cold pipe is placed on the conveyor 1, which carries it away for further processing. Another hot pipe can be filed for processing. For the entire duration of the operation of the tank 4, the coolant is vigorously stirred by the side pipes 7 and its temperature is maintained at an ambient temperature using an external cooling system (not shown).
    The cycle time depends on the pipes being processed. It is about 30 seconds, not counting the actual immersion time, which depends on the type of metal and the size of the pipe.
    The proposed installation is most suitable for long pipe lengths (greater than or equal to 15 m) with a diameter of 70-150 mm, with a large ratio of diameter to thickness — about 25. Such pipes after treatment do not have noticeable longitudinal deformations.
    The cycle of operation of the cooling device 10 is such that it can be used either at the exit of the n-agglomerating furnace or at the exit of a hot stamping installation, such as a press for squeezing through a glass point with 5 aiming to subject the metal to hard metal or hardening.
    In the cooling device (Fig. 7), the hot pipes 40 are fed by a roller conveyor from one side of the cooling tank 41 and removed coldly from the other side of the tank using a conveyor belt (not shown). The lever 42 serves to laterally transfer the hot pipe to the immersion device.
    The immersion device is represented by a shoulder 44 of the lever 43, provided with an angle 45. The immersion is performed by turning the lever 43 0 and the cold pipe exits by reverse turning the lever 43.
    In another embodiment of the immersion device, pipes may be immersed in an inclined position, with one end of the pipe entering
    in contact with cold liquid earlier than the other end. The slope, which can be several degrees, can be obtained by continuously varying the relative angular displacement of some levers relative to others or by using variable and continuously increasing shoulder thicknesses in the vertical direction of the spacing from angle 17 for different levers 9 distributed along the tank, or by means of other suitable means.
