    An apparatus for supplying fluids to a converter has a rotary joint coupled to a trunnion shaft, one end of the rotary joint being connected to fluid supply pipes and the other end to fluid conduits communicating with tuyeres at the bottom of the converter. The rotary joint comprises a fixed casing and a rotary assembly, that is sealedly and rotatably fitted in the casing and connected to the trunnion shaft. The rotary assembly has a cylindrical member fitting in the casing. A plurality of axially spaced, circular communication grooves are provided in at least one of the internal surface of the casing and the external surface of the cylindrical member. The cylindrical member is provided with a passageway which opens into the communication grooves at one end and into the atmosphere where the cylindrical member emerges outside the casing at the other. The fluid supply pipes are attached to the casing so as to communicate with the communication grooves and the fluid conduits to the exposed part of the cylindrical member so as to communicate with the passageway.

    2. The device according to claim 1, characterized in that the inside tube is located concentrically with a gap relative to the inner tube, while the gap cavity on one side is connected to the protective gas supply pipe to the converter, and:
    protective collector
    the other is with gas.
    3. The device according to claim 1, wherein it is provided with a cylinder mounted concentrically with a gap relative to the cylinder and the inner tube with an outer tube.
    The invention relates to devices for supplying fluids (e.g., various liquids or gases) to a converter with a bottom blow or with a combined (top and bottom) blow. The aim of the invention is to simplify the manufacture of the device. Figure 1 is a schematic representation of a converter and a device for supplying fluids to it; on Fig.2distribution node, cross section; on fig.Z - groove in the distribution node, the cross-section | 4 shows a distribution assembly (embodiment), cross section; Fig. 3 is a section A-A in Fig. 4, Converter 1 with a retort 2 contains a casing 3 and a refractory lining 4. The bottom 5 has at least two tuyeres 6, each of which has a hole 7 for introducing oxygen for metal refining and an annular nozzle 8, surrounding the nozzle 7 for introducing a protective gas (for example, propane). Retort 2 is supported by a hollow pin 9, which is located on axes 10 and 11. Axle axles are held by bearings. Axis 10 is connected to a drive through which retort 2 tilts on pin 9. Axle 11 is connected to distribution unit 12, which supplies oxygen and other working media to nozzles 7 and 8 and the cooling system. The distributor unit 12 is fixed by a flange 13 to the end surface of the driven axle 11 of the trunnion 9. The distributor unit 12 consists of a fixed casing 14 and a rotation structure 15. As shown in figure 2, the casing 14 contains three cylinders 16-18, which are assembled in steps with the knee. Knee 19 is connected to the oxygen supply pipe 20. The middle cylinder 17 of the housing 14 has a cylindrical protrusion 21 inside and is connected to a cooling water supply pipe 22 in communication with an annular space 23 formed inside the protrusion 21. A cooling water outlet pipe 24 communicates with the annular space 25 between the middle cylinder 17 and the protrusion 21, both pipes are separated from one another by a circle. The structure 15 has an inner tube 26, an outer tube 27 and an outer cylinder 28, the outer tube 27 and the outer cylinder 28 being coaxially connected to the housing 29. The inner tube 26 has a cylindrical movable part 30 that rotates inside the cylinder 18 and the casing 14. Between the cylinders 17 and 18 and the movable part 30 is inserted a ball bearing 31 to facilitate rotation of the structure 15 and a ring 32 to prevent leakage of fluid. One end of the inner tube 26 communicates with the elbow 19, the other with the intermediate tube 33 inserted into the horizontal hole 34 in the trunnion 9 with the axle 11. The ring 35 is installed where the outer tube 27 is inserted into the protrusion 21 to prevent fluid leakage. The annular space 36 between the pipes 26 and 27 communicates with the annular space 23 inside the protrusion 21, while the cooling pipe 37 is connected to the housing 29. Consequently, the cooling water supplied from the pipe 22 flows through the annular space 36 between the inner,
    3
    26 and outer 27 pipes (figure 2, arrow a) and then to the retort cooling system through pipe 37. Outer cylinder 28 of the structure
    15 is turned in cylinder 16, as shown in FIG. The ball bearings 38 are inserted between the outer cylinder 28 and the cylinder 16 to enclose the rotation of structure 15. Two circular grooves 39 and 40 are cut on the inner surface of the cylinder.
    16 and run separately along its longitudinal axis. The cylinder 16 of the casing 14 has communicating windows 41 and 42, which respectively connect the grooves 39 and 40 from the outside. Tubes 43 and 44 are connected to the cylinder 16. The outer cylinder 28 of the rotary structure 15 has buttons 45 and 46, which communicate with the grooves 39 and 40, respectively. Windows 45 and 46 are rotated into outer cylinder 28 and are reported
    with grooves 39 and 40 and with section 47 of cylinder 28. Windows 45 and 46 are circumferentially separated, and shielding gas supply pipes 48 and 49 are connected to section 47 and communicate with windows 45 and 46, respectively. Shielding gas, supplied from pipes 43 and 44, flows to pipes 48 and 49 through windows 41 and 42, grooves 39 and 40, and windows 45 and 46.
    The sealing rings 50 are located on both sides of each groove 39 and 40. The end of the annular space 51 between the outer pipe 27 and the outer cylinder 28 is in communication with the annular space 25 formed by the middle cylinder 17 of the casing 1 and the protrusion 21. One end of the annular space 51 between the pipe 27 and the cylinder 28 communicates with cooling water supply pipe 52 connected to body 29 of structure 15.
    The cooling water returned from the cooling system through the pipe 52 passes through the annular space 51 between the pipe 27 and the cylinder 28 (Fig. 2, arrow c), and then is discharged through the pipe 24.
    The opening 34 communicates with the chamber 53 located in the pin 9. The chamber 53 comprises a main 54 and one end of the intermediate pipe 33 passes through the front wall of the main 54 and is welded to it. The trunnion 9 has a vertical opening 55 extending downwardly from the chamber 52, with intermediate 3764
    pipe 56 passes through this hole. The upper end of the intermediate pipe 5, passing through the bottom wall of the line 54, is welded to the line 54. After welding, the line 54 is closed by the screen 57.
    An oxygen supply pipe 58 connected to the lower end of the intermediate pipe 56 leads to the pipe 59 extending below the bottom 5. Oxygen is injected into the retort through the nozzle 7 branching from the pipe 59, the sleeve 60 is installed around the axle shaft 1 1.
    The movable part 30 has several horizontal openings 61, which are circumferentially spaced coaxially from each other. The shielding gas supply pipes 48 and 49, the water supply pipes 52 and 37 extend from the rotation structure 15 and are attached to the sleeve 60 so that with horizontal holes 61. The pipes 48 and 49 passing behind the sleeve 60 in the direction of the bottom 5 are connected to the nozzle 8 of the protective gas inlet.
    When the trunnion 9 is rotated, the structure 15 connected to the trunnion rotates with it relative to the casing 14. The rotation of the structure 15 does not interrupt the connection between the oxygen supply pipe 20 and the pipe 58, the protective gas supply pipes and 44 and the pipes 48 and 49 and pipe 29 water supply and pipes 37 and 52 of the water supply inlet and outlet, as well as pipe 24 release of cooling water.
    I
    During the converter operation, a uniform amount of oxygen, regulated by the flow valve 62, is supplied to each lance 6. The protective gas injection rate must be controlled for each lance 6, depending on the degree of erosion of the bottom 5. For this purpose, the protective gas supply pipe 43 and 44 connected to distribution unit 12, have flow control valves 63 and 64 (FIG. 1). This allows an independent control of the flow rate of input protective gas for each tuyere 6, thereby preventing an increased erosion of the retort lining.
    The communicating groove may be on the casing and on the outer cylinder.

    Figures 4 and 5 show a variant of the device. The use of the invention is ambitious, where not two, but four pipes can simplify the manufacture of a protective gas supply device connected to supply the working media to the distribution node, the verter.
