    A sliding closure unit includes at least one stationary plate having therethrough a discharge opening, and a movable plate mounted in sliding contact with the stationary plate, the movable plate having therethrough first and second discharge openings and including a closing area. Guides define alternative first and second paths of movement of the movable plate in directions along respective first and second tracks extending between the closing area and the first and second discharge openings of the movable plate. A single drive is connected to the movable plate for moving the movable plate along a selected such path between a closed position whereat the closing area is aligned with the discharge opening of the stationary plate and a selected open position wherein one of the discharge openings of the movable plate is aligned with the discharge opening of the stationary plate. The guide structure is adjustable when the movable plate is in the closed position thereof, without moving the movable plate, to selectively switch between the first and second paths. The movable plate includes three rectilinear surfaces defining edges of the plate and relatively positioned to extend along the three sides of an imaginary equilateral triangle. Centers of the first and second discharge openings of the movable plate are located on bisectors of respective angles of the imaginary triangle.

    one
    The invention relates to metallurgy, in particular to the pouring of metal from ladles with a drain hole in the bottom.
    The aim of the invention is to reduce the dimensions of the gate.
    FIG. 1 shows a slide gate, section; in fig. 2 shows section A-A in FIG. one; in fig. 3 - the same, with a different form of org-anans of turning and carrying frame; in fig. D and 5 are the different positions of the supporting frame with the locking plate of the gate; in FIG. 6, section B-B in FIG. 3; in fig. 7 shows the geometric properties of the locking plate in FIG. 8 - the second variant of the slide gate, general view; in fig. 9 is a section bb of FIG. eight.
    The slider gate (Figures 1 and 2) is a three plate and is fixed to the bottom of the ladle, for example, an intermediate tank of a continuous casting plant. The lower part of the tank is indicated by the position 1, the lining by the position 2.
    A refractory shaped brick 3 is inserted into the opening of the outer shell with an opening 4, which forms the beginning of the adjustable channel passing down through the grill.
    To control the melt plowing, the shutter contains three refractory locking plates: one fixed top plate 6 with a hole 7 fixed to the top of the casing 5 of the gate, movable locking plate 8 and a fixed bottom plate 9 with a hole coaxial with the hole 7. The bottom plate 9 is an integral part of the removable bottom part 10 of the shutter (shown by dash-dotted lines).
    The movable slide plate 8 is covered by a metal support frame.
    11, to which a linear actuator is attached through the hinge 12, in this case, mounted on the axis 13 is a hydraulic valve 14 with a rod 15 (FIG. 4). The locking plate 8 has two round through-holes 16 and 17. Near these holes is a locking zone 18 of the plate (hatched, Fig. 2 and 3). In the shown closed position of the gate, the stop zone 18 is between the gap
    openings of the fixed upper 6 and lower 9 plates.
    By activating the hydraulic cylinder 14 and by means of special turning bodies for selection, one of the two holes 16 or 17 can block the holes in the fixed plates to allow the melt to flow out, and by means of appropriate control of the drive, throttling flow cross section.
    As an organ of rotation for moving the locking plate 8, on each side of the gate, double shoulders are installed pivotally mounted with the help of puffs on the upper part of the body 5 guide lever 19. The guide levers form guide means fixed to the carrier frame 11 at a moving gate. At one of the ends The levers 19 are directed through the pins 20 to a pull 21, which keeps the levers parallel to each other. Both directional levers 19 with thru 21 allow the permutation of the one shown in FIG. 4 to the second position indicated by the dot-dash line in FIG. 5, for example, by means of a pin 22 per tonne 21, which can be inserted into the corresponding fixing holes a or b on the upper part of the housing. The swapping is done accordingly with the shutter closed. The shifting of the levers 19 can occur manually, for example, with the aid of a lever 23 fixed to t 21, through which, if necessary, the pin 22 can be removed from one of the fixing holes and re-inserted into another hole. The locking of the arms in their both end positions can be fixed in another way.
    In order to interact with the guiding levers 19, the carrier frame 11 is equipped with leads in the form of two strips parallel to each other 24-27. In the embodiment shown in FIG. In the 4 position, the gate is guided between the arms by the bars 26 and 27, and in the final position by the bars 24 and 25.
    In each of the end positions, both guiding levers 19 provide for

    Placing the plate 8 in one of the two directions x or y, which extend from the locking zone 18 of the plate to both openings 16 and 17. These directions X and y are also parallel to the strips 26, 27, 24 and 25 on the supporting frame 11.
    Both end positions of the guide arms and the corresponding movements of the gate are shown in FIG. 4 and 5. In the fixed position (Fig. 4), the levers direct the gate in the X direction, i.e. the shutter plate with the frame 11 is moved between the locking position shown and the position shown by the dot-dash in which the hole 16 coincides with the fixed hole 7. In accordance with FIG. 5, the levers 19 move in a fixed position in the direction between (according to the locking position in FIG. 4) the locking position and the position at which the other hole 17 of the mash plate coincides with the fixed hole 7. When you rearrange the directions | There are no movements between the two end positions of the gate with the slide plate 8 in the locked position, so the rotation of the turning bodies is possible without any significant effort. Further, the gate moves in the X and U directions. a purely linear movement, i.e. The gate does not rotate and only the cylinder 14 of the actuator makes a certain inclination around its axis 13 of attachment.
    The directions i, a) form an angle o (fig. 2) j, preferably 60 °. The directions X,; j passing through the centers of the openings 16 and 17, respectively, intersect at the point 28 of the locking zone 18, this point defines the only locking position of both the through holes.
    A possible other implementation of the direction of 1X means that caused-. The design of the supporting frame 11 for the slide plate 8 (Fig. 3 and 6) is somewhat different.
    Two fixed pairs, preferably recessed in the upper part, act as fixed guides, which define the rectilinear directions of the movement of X or at the bolt.

    Cases 5 of slots 29 and 30. In the two opposite frames of frame 11, axles 31 are inserted, each of which, respectively, enters slot 29 or 30. Both slots 29 run parallel to the tension x and slot 30 are parallel to direction J. Each pair of slots is provided with an adjusting tongue 32, which has a radial slot 33. In order to consistently expose the radial slots 33 of both sleeves 32, the p-blades are connected to each other

    In this case, formed through 1 1, it forms the jjMRCTe gate with it.
    A linear actuator is fixed on the carrier frame 11 through the hinge 12, for example, the hydraulic usun-tfuvpf is represented only by the rod 15). On the side of the passage openings 16 and 17 of the locking plate, there is located on hatching a shut-off area 18 of the plastics, which is located in the closed position of the shutter between the through openings - 25 of the upper upper legs and the lower 9 of the plates.

    The means on the casing of the gate and the correspondingly 55zb and 37 are missing, the opening 17 of the pivotal pins on the carrier frame can move along the trajectory jp, and also open in another mega position, i.e. to 1) place with
    for example, pins 31 can be a fixed hole /. Both tracks are located on the axis of symmetry of the gate, which passes through ujapHHp 12.
    The slide gate according to the second variant (Fig. 8 l 9) from J; the main version is the organon of rotation, which in this case direct the locking plate along two arcuate trajectories m. The overall design (three-plate) of the zptrpk corresponds to the design of the PS variant (fig. 1 and 2 ).
    The movable locking plate 8 of the clamp in the metal compartment X and J intersect at point 28 on the axis of the fixed throughput hole 7. In order to ensure accurate alignment of the holes 16 and 17 with the hole 7 in the open position, it is possible to restrict one or the other rotation movement of the shutter by means of adjustable stops (not shown).
    Preferably, the turning point of the linear actuator (hinge 12) is performed on the frame 11 (Fig. 9), on the axis of symmetry between holes 36 and 37. Another turning point can also be chosen, since the direction of the drive force does not pass through one of the two holes.
    Swapping opi aHOB rotation on one or another trajectory of movement h occurs when the shutter is closed, when both pairs of holes 36, 38 and 37, 39 are aligned with each other. Kingpin 40 in this case can be easily rearranged.
    FIG. 7 shows an example of a movable refractory stopping plate 8. The diameters of both holes 16 and 17 are different. In the locking zone 18, the shutter plate is provided with a device 41 for inserting 1 joint into the channel with the shutter closed. Position 42 marked the accession of the corresponding g-pipe to the base frame 11, while the gas channel passes through the frame and inside the locking plate to the device 41.
    Essential for the backing plate are some geometrical ratios in part of the plate area and its profile, along which it is precisely enclosed by the supporting frame 11. The main limitation of the plate surface is formed by three straight sections 43, 44 and 45, which lie
    on three sides e, f, g of an equilateral triangle. Both holes 16 and 17 are so located on the surface of the plate that their centers respectively lie on the bisector of r or S of the indicated triangle. The corners of the plate 8 can be cut, however, preferably three straight sections 43-45 are connected by three arcs 46-48, with two arcs 46 and 48 with the same radius passing concentric with corresponding holes 16 and 17. A third arc 47 can
    5 also have the same radius, however, the radius can be chosen larger or smaller, so that (in combination with the corresponding frame design) the plating of the plate into the frame is ensured only in one position. The plate 8 in the frame 11 is clamped by means of clamping screws 49, which are located on one side of the frame 11 and press the straight line
    5, whereby the plate segments 44 and 45 are pressed against the other two sides of the frame. The refractory plate 8 can be held in the metal frame 11 in another way.

    In the described geometrical design, the plates of the direction of motion and are parallel to segments 44 or 45, they intersect at the bisector of triangle t (locked position). This form allows, based on the specified hole diameters and stroke lengths of the shutter, optimal use of the wear-resistant refractory material: the position of the point 28 and the centers of the holes 16 and 17 also form an equilateral triangle, which, from all sides, is surrounded by the edge of the plate surface.
