    A pair of refractory plates includes a stationary bottom plate having a discharge opening and a movable plate having two discharge openings. The movable plate is mounted for sliding movement with respect to the bottom plate about a center of rotation between a center closed position and opposite open positions. The discharge openings of the movable and bottom plates are centered on a common circular arc centered about the center of rotation, and the discharge openings of the movable plate are positioned symmetrically on opposite sides of the discharge opening of the bottom plate in the closed position. The bottom plate has a second discharge opening at a position between the circular arc and the center of rotation. The discharge openings of the bottom plate are centered on a radial line extending from the center of rotation and intersecting the circular arc, such radial line corresponding to a radial center line between the discharge openings of the movable plate in the closed position.

    FIELD OF THE INVENTION The invention relates to metallurgy and concerns the pouring of steel from containers with a slide gate.
    The aim of the invention is to increase the service life of the slide gate
    FIG. 1 shows a slide gate, section; in fig. 2 — bottom plate, horizontal projection; in fig. 3 - hearth plate with a picture of wear, a partial section; in fig. 4 - a pair of plates in the open position; in fig. 5 - used bottom plate, horizontal projection; in fig. 6 - used swivel plate, top view on sliding surface.
    The slide valve contains a heat-resistant inlet sleeve 1 of the slide gate located in the heat-resistant lining of the metallurgical ladle. In addition, the shutter is equipped with a fixed bottom plate 2, a swivel plate 3, and an outlet sleeve 4. The bottom plate 2, which is attached to the inlet sleeve 1, has two drain holes a and b located along the axis of symmetry of the rotation or rotation zone of the plate 3
    x, as well as a uniformly worn plate 3.
    As is known, the wear sections 7 and 8 in the holes a, b and d, e of the bottom and slide plates 2 and 3 are formed first as a result of a change in the direction of the injection stream with a throttling shifted position (Fig. 3), and as a result of melt penetration between the surfaces 5 and 6 of the slip of the pair of plates 2 and 3, mainly in the area of the throttling edges. If there is a leaked melt, then when the plate 3 is moving relative to the fixed bottom plate 2, both plates are damaged as a result of the formation of sections 7 and 8 of characteristic wear.
    When shown in FIG. 5 and 6, the wear of the plates 2 and 3, the device for adjusting the opening and closing of the shutter with the aperture d of the plate 3 acts on one side of the axis
    5 x symmetry zone adjustment
    (Fig. 2) so that after switching the adjustment device on the other side of the axis, when the opening of the plate 3 is turned on, a portion can be obtained

    marking the closing position, from the wear plate 30, which is located.
    First, one thing, and after it is worn, the other can be connected to the passage opening from the inlet sleeve 1, namely by turning it 180 in the direction of arrow A according to FIG. 5. To the sliding surface 5 of the bottom plate 2 is pressed tightly, but with the possibility of sliding the surface 6 of the plate 3, which also has two flow holes d and e. Both flow holes are located symmetrically on both sides of the axis of symmetry X along the turning arc y around the pivot point O of the gate through the coaxial axis of the flow ports with and a and the inlet
    sleeves 1 and bottom plate 2. I
    Practically, the placement of the flow holes a and b of the bottom plate in symmetry x across the arc of rotation y or the flow holes d and e of the plate 3 gives an elliptical shape of the plates 2 and 3, especially since the areas 7 and 8 that appear as a result of wear also have an elliptical shape ( Fig. 5 and 6), in the same figures, a worn base plate 2 is shown after rotation by 180 ° in the shear plane in both holes 5
    opposite the one shown. wear area. Consequently, due to the rotation of the plates 2 and 3 in the shear plane on and by means of the above-mentioned switching of the adjustment device, two throttling edges can be used in each flow-through hole a, b and d, e.
    However, for practical purposes, it is recommended to operate the adjustment device only on one side of the centerline of the x-axis of symmetry, and in this case one of the flow-through holes of the plates 3 serves as a gating hole, and another hole for burning out, for example, an injection nozzle for oxygen. The hardened metal is installed under the holes c and d of the inlet sleeve 1 and the bottom plate 2 and the duct is freely burned. In addition, gas or other materials for melt metallurgical processing can be fed through the burning hole into the ladle.
    When using three-plate slide gates, a pair of plates 2 and 3, in accordance with the proposed shutter, is equipped with another bottom plate
