    This invention relates to a device for cleaning an auxiliary oxygen tuyere tip inserted into a metallurgical ladle, in particular an auxiliary oxygen tuyere carrying a measuring and / or sampling probe containing a cleaning head, surrounding the oxygen auxiliary tuyere tip and contacting with it during the cleaning process , while the cleaning head and the oxygen auxiliary tuyere possess relative mobility in the direction of the axis of the auxiliary oxygen tuyere.
    The purpose of the invention is to improve the measurement accuracy.
    Figure 1 shows the tip of the tuyere; figure 2 - the proposed device with a partial section, side view; fig. 3 - the same horizontal projection.
    The auxiliary measuring oxygen lance 1 is brought into position above the throat 2 of the steelmaking converter 3, at a distance of 4 from the blowing lance 5, a measuring rod 7 is provided at the tip 6 of the measuring oxygen tuyere, measuring passage
    in the direction of the axis 8 of the oxygen lance 1. The auxiliary tuyere can be raised and lowered by means of an actuator (shown). During the measurement, the auxiliary oxygen lance 1 with the measuring probe worn on the contact rod 7 is immersed in the melt in the steelmaking converter 3, namely, the slag floating on the melt, and the tip 6 of the auxiliary lance repeatedly sinks into the slag.
    On the end side 9 of the auxiliary tuyere tip there is an annular recess 10 into which the upper end of the measuring probe can be inserted, which, as a rule, can prevent slag or melt from entering between the measuring probe and the contact rod 7. This recess 10 and the cone adjacent to the recess The side 9 of the tip of the auxiliary tuyere should be cleaned of sediment from slag or metal so that after the measurement, i.e. after removing the measuring probe from the contact rod 7, they could flawlessly receive the new measuring probe, while ensuring contact between the contact points 51 and the corresponding contact points of the measuring probe.
    For this purpose, a device 12 for cleaning the auxiliary tuyere tip 6 is provided, equipped with a cleaning head 13, on the upper side of which a milling head 1A is mounted. The cleaning head 13 is formed of two parts 13, 13, constituting a hollow cylinder together. The planes 15 of the connector are held vertically, i.e. through the axis 16 of the cleaning, heads 13. The cleaning head 13 has a body 17, also made detachable, in which a milling head 14 is mounted on the rollers 18, also made detachable, having the possibility of rotation in the vertical and horizontal directions. Each part 17, 17 of the housing 17, respectively, is provided with a protruding lever 19 by means of a vertical axis 20 fixed on the slide 21 with the possibility of oscillation in the plane of rotation, as a result of which parts 17 and 17 of the housing 17 and the hours located in them

    These 14 and 14 milling heads 14 can move as the pliers of position A (dash-dotted line), in which they are in the diluted state, to the closed working position B (solid line, FIG. 3).
    Caliper 2 with two vertical guides 22 mounted
    10 to the arm 23 with the possibility of raising and lowering in the direction of the axis I6 of the cleaning head 13. Dnep of raising and lowering is pneumatic cylinder 24 pivotally connected to the bracket,
    15 piston rod 25 which is sariirno connected with a flip lever 26, hinged on the bracket 23 by means of an axis 27 kachani, Swing axis 27 causes lifting and lowering
    25 caliper 2.

    The closing point of the cleaning head in working position B and opening in position A, in which it is in a diluted state, serves as a pneumatic cylinder 29 fixed on a support 21, the piston rod 30 of which approximately coaxially engages with the transverse bracket 31, the corresponding end 32 and 33 which, through the E-hinged cover 34, is hingedly connected with the corresponding lever 19 protruding from parts 17, 17 of the housing 17. By moving the transverse bracket 31 in the direction of the arrow 35 to the position shown in Fig. 2 In this case, the levers 19 swing around their axes 20 and the parts 13 and 13 of the clearing from the HEAD 13 move away from one another, moving to position A, in which they are in a diluted state.
    For a swinging swivel movement of the milling head 14, a horizontal plate 36 having the shape of a semicircular ring is provided on each part 14, 14 of the milling head 14; both of them are located inside the casing 17 of the cleaning head 13. To each of these plates 36, the hinge is connected to the end of the hinge lever 37. The opposite ends of both hinged levers 37 are movable

    they are connected to each other by means of a two-arm lever 38, concentric with the possibility of rotation of a swing mounted on the axis 39, mounted on a support 21. With one of the arms of the two shoulders 38, it is eccentric, i.e. at a distance of 40 from the axis 39 of the swing, the piston rod 41 of the pneumatic cylinder 42, which is mounted on an additional support on the slide 21, engages.
    As can be seen from FIG. 3 for a non-oscillator with a milling head 14, i.e. when the double-arm lever 38 is in a central position, the axles 43, by means of which the pivot arms 37 are fixed on the double-arm lever 38, are located on. one straight line with axles 20, with the help of which the arms 19 are hingedly connected to the caliper 21. Thanks to this, parts 14 and 14 are milling cutters. As soon as the measuring probe is removed after the measurement has been made
    The NOI of the head when diluting or closing the cleaning head 13 is not perfect 25 s of the contact rod 7, the arm 23 is rotatable. For guiding the device 12, with the execution of the transverse bracket 31 when it is moved for the purpose of diluting or closing the cleaning head 13, the guide rollers 44 mounted on the transverse bracket 31 can be turned
    2 and 3, position D. 30. In this case, parts 13 and 13 of the cleaning head 13 are in the diluted state in position A, and the support 21
    tip 6 oxygen mine. They form among themselves, in a horizontal projection, the angle 52, which is smaller than the maximum angle of the swinging pivoting movement. Mounted on the milling head of the bolt 53 (it is also made detachable) serves to protect the rollers 18.
    The bracket 23, on which the caliper 21 is mounted, with the help of the actuator 54 can be moved or deviated respectively from the stop position to the side of the converter 3 into the one shown in FIG. 2
    and 3 position in the direction of the double arrow 55, in which the axis 16 of the cleaning head 13, shown in the working position B, is on the same straight line
    with axis 8 oxygen mine.
    The operation of the device is as follows.
    As soon as the measuring probe is removed after the measurement
    from the contact rod 7, the bracket 23 of the device 12 with the help of
    25 with the contact rod 7, the bracket 2 of the device 12 with the help of
    2 and 3, position D. 30. In this case, parts 13 and 13 of the cleaning head 13 are in the diluted state in position A, and the support 21
    guide rails 45 fortified on a support 21.
    In order for the contact gum 7 to be reliably centered with parts 13 and 13 of the cleaning head 13 when the divorced state deviates from position A to working position B, both parts 17 and 17 of housing 17 are provided with centering lugs 46 extending beyond connector lines 15. For reliable movement of the cleaning head 13 in the direction of the axis-8-oxygen lance 1 in the housing 17, there are also provided detachable cylindrical guide surfaces, surfaces 47, formed in each case by an annular plate 48 of semicircular shape, on which 50 DUHs are preferred.
