    An immersion cooling apparatus includes a mechanism for immersing a hot metal pipe with the axis thereof directed horizontally in a cooling tank containing cooling liquid, and a mechanism for locking the immersed pipe in position in the cooling tank. While the locking mechanism is preventing the pipe from moving, a nozzle extending toward the interior of the pipe in the direction of the pipe axis injects cooling liquid into the pipe. The cooling liquid thus injected flows completely through the pipe so that the pipe being cooled is not injured or bent.

    (54) INSTRUMENT FOR COOLING OF PIPES
    The invention relates to devices for rapidly cooling hot metal pipes by immersion in a cooled liquid.
    A device for forced cooling of steel pipes is known, which represents 5
    a ring sprayer with a slit facing the surface of the pipe. The cooling water is sprayed with jets of air supplied through several nozzles 1.
    The drawback of the device for cooling the pipe by spraying is that it is significantly un-. during the spraying fluid.
    Closest to the proposed device is a device for cooling pipes by immersing them, containing a container with a cooler, guides with a bed under the pipe at the end of them and discharging conveyors located opposite to the bottom, located on the bed axis and a nozzle for supplying a cooler into the pipe and 0 lever mechanism, the shaft of which is located above the container parallel to the axis of the bed 21.
    When cooled by immersing the pipe in a cooling liquid, it is necessary to ensure that cooling is 28
    uniform and the pipe would not change its shape, and this can be achieved by creating sufficient turbulence of cooling water around the pipe.
    However, the nozzle installed in the tank cannot provide sufficient mixing of the cooler and ensure uniform cooling.
    Free tube rolling in the direction of the tube (they are at the bottom of the bed and the transfer lever of the lever mechanism can lead to the tube being immersed in the tank in an inclined position, which will lead to uneven cooling.
    In addition, a tube can receive various types of stress or scratches during free-wheeling. Since the pipe is not held in a horizontal position, its front or tail part is in contact with the coolant before immersing the rest of it, which causes a large difference in temperature between different sections of the pipe, and this difference. may cause pipe deformation due to thermal stress. 39 The absence of a tube in a known device can lead to pipe movement in the direction from the nozzle due to a jet of water supplied under pressure, thus HC provides a constant distance between the nozzle and the pipe, as a result of which the pipe can be deformed during cooling. The purpose of the invention is to increase the cooling efficiency and prevent pipe deformation. The goal is achieved by the device for cooling pipes containing a container with a cooler, guides with a bed under the pipe at the end and opposite to them discharge conveyors inclined towards the bottom, a nozzle for cooling the pipe and a lever mechanism located on the bed axis; the shaft of which is placed above the container parallel to the axis of the bed, is provided with vertical lorzshevy tube clamps installed above the container in the bed with their pull-out support, in which the shaft of the lever mechanism is mounted, and each Its second lever is made in the form of a part mounted on the shaft with a longitudinal groove and located in it with the possibility of reciprocating movement of the sliding part from the drive. The insertion of piston clips above the tank parallel to the bed axis prevents the pipe from moving in the opposite direction due to high pressure water from the cooling water nozzle, maintaining a constant distance between the nozzle and the tube, as a result of which a stable flow of cooling medium is guaranteed. the pipe is prevented from being deformed during cooling. Performing the lever of the lever mechanism with a composite ensures the horizontal position of the peridual tube by entering it into the container so that it can evenly be dipped into the container evenly over the entire length, and the tube along the guides can be transferred quickly and without impacts, thereby preventing deformation of the latter and increasing the cooling efficiency. FIG. 1 schematically shows the proposed device, side view; in fig. 2, section A-A in FIG. 1. A device for cooling pipes includes a tank 1 with a cooler (in this case with water), guides 2 which are inclined to the bottom and have a bed 3 under the pipe 4 and the discharge section 5. Guides (there are four of them in this case) are located in the longitudinal direction of the tank and each of them is supported by the pillar 6. Discharge conveyors are installed opposite the rails in the tank, which have drop arms 7 mounted on the drive shaft 8 in bearings 9 mounted on the rack 10, and closed chain transmissions 11. Each chain transmission has clamps 12 located along the chain with equal gaps between them. Chain transmissions are driven by a drive mechanism (not shown) through wheel 13. A discharge platform 14 is installed on the output side of the chain transmission. A nozzle 16 of coolant supply is located on the bed axis in the tank 15. The cooler (water) in the Forsu 1ku is supplied from the source 17 of the liquid through a pressure pipe 18, ensuring the formation of a flow of liquid through the pipe. The cooling device also comprises a lever mechanism having a shaft 19, which is mounted in bearings 20 of a stationary support 21 and located above the container parallel to the axis of the bed. Each lever of the lever mechanism is made in the form of a sliding part 23 mounted on the shaft 19 of part 22 with a longitudinal groove and located in it. The sliding part has a hydraulic (pneumatic) actuator 24 of reciprocating movement. Both ends of the shaft 19 are fastened with one end of the rod 25, their other ends are connected to adjusting threaded rods 26, which are fixed in the support 21 by nuts 27 with the possibility of vertical movement. In the stationary support 21, vertical piston clamps 28 installed along the tank are mounted, which are intended to press the pipe against the bed of the guides and thereby clamp it. For vertical movement of the clamps, hydraulic cylinders 29 with rods 30 are mounted. The device operates as follows. First, the adjusting threaded rods 26 are moved up or down in order to rotate the levers of the lever mechanism and thereby adjust the position at which the sliding parts 23 of the levers intersect the inclined portions of the guides 2, i.e. to obtain an equalized position B of pipe 4. This position B will be set appropriately for the pipe, which should be located horizontally above the level of the cooler in the tank. When the alignment B of the alignment of the pipe is adjusted, the sliding parts 23 of the levers of the lever mechanism are advanced and remain in the intersection position of the inclined sections of the guides. The pipes to be cooled5 4 are fed one after the other onto the opposite side of the vehicle (not shown). The pipe laid on the inlet ends of the guides 2 begins to roll down along them, then it is stopped by the sliding parts of the 23 arms which temporarily hold the pipe in a horizontal position. The hydraulic or pneumatic actuator 24 of the reciprocating retraction or movement of the sliding parts of the levers is then put into operation, as a result of which the pipe, being in a horizontal position, rolls down the inclined ejection sections of the guides into the tank 1 with the cooler until it is inclined up the surface of the bed 3. When the pipe is thus blocked, the hydraulic cylinders 29 of the actuator of the vertical movement of the clamps 28 are turned on to feed the latter down so as to hold between the clamps and the bed guides.
    As soon as the pipe is clamped, coolant is supplied to it by means of a nozzle 16, the flow of which goes through the pipe, at the same time the specified flow of water from the nozzle supplies the inside of the pipe and the cooling liquid located at the inlet to the pipe. The flow of coolant through the pipe quickly and evenly cools it along its entire length. The cooled pipe is in a clamped position, which prevents it from moving in the longitudinal direction under the action of the flow of coolant flowing inside the pipe.
    At the end of the cooling operation of the pipe, the clamps 28 are lifted and the ejection levers 7 of the discharge conveyor are rotated counterclockwise, as shown in FIG. 1. As a result, the pipe through the discharge section 5 of the guides 2 is fed to chain drives 11, which move it up to the unloading platform 14. The pipe located on the platform is fed into the zone for performing the next process operation using a transport device (not shown) such as a roller table. Speed adjustment

    the movement of the chain drives allows the cooling time to be adjusted in order to ensure the desired cooling efficiency of the pipe.
    5 The proposed device for cooling pipes by immersion in a cooling liquid makes it possible to pre-align pipes in a horizontal plane, thereby ensuring uniform cooling, while preventing their distortion and deformation. In addition, it provides smooth, non-impact movement of the pipes along the guides without rolling them along the latter and allows for increased cooling efficiency.
