    A swivelling sliding closure unit includes a stationary refractory plate having a discharge opening and supported by a stationary housing. A swivel pin is fixed to the stationary housing, and a swivel lever having first and second ends is mounted on the swivel pin by a gimbal bearing. A movable refractory plate has therethrough a discharge opening and is supported at the first end of the swivel lever by a movable housing to enable pivoting of the movable refractory plate with respect to the swivel lever. The swivel lever is rotated about the swivel pin to move the movable refractory plate between positions enabling and blocking discharge of molten metal from a metallurgical vessel and also to a replacement position. A rolling element is mounted on the stationary housing, and a raceway formed on the second end of the swivel lever abuts the rolling element. A bracket is hingedly connected to the stationary housing and is connectable to the swivel lever when the swivel lever is in the replacement position thereof. Thereby, upon removal of a clamp which clamps the swivel lever to the swivel pin, the swivel lever may be swung to an open position enabling replacement of the refractory plates.

    The invention relates to metallurgy, in particular to the casting of metal from metallurgical vessels, such as ladles.
    The aim of the invention is the convenience of operation.
    Figure 1 shows the bottom of the foundry bucket with a rotary valve (lever
    the tracks 24 to the roller 11 of the housing 3 correspond to the operating conditions of the bucket 1. The creation of an optimal elastic pressure on the surface between the sliding surfaces of the bottom plate 6 and the valve plate 26 is achieved by matching the cardan axis 27 of the frame 25 by
    dampers - in the initial position), a view of the simple movement of the clamping element from above; Fig. 2 shows a flap body, 23. The elasticity may be in the pivot arm 20 or created by a spring device 29 with a progressive dotted pattern indicated by the clamping element and the pivoted pivot arm, top view; FIGS. 3 and 4 show a butterfly valve at different positions; on fig.Z - rotary valve, longitudinal section; figure 6 - the inner side of the swivel lever top view; Fig.7 - section aa in Fig.6.
    The device contains a casting ladle 1, on the bottom of which a filling hole 2 is made and the casing 3 of the rotary valve is fixed with screws 4, the casing 3 is made a notch 5 for the bottom plate 6, and also a support 7 for the trunnion 8, a spacer 9 and
    bearing bracket 10 for roller 11, axis 12 of which is on straight 13, passing through the center of the pivot, axle 8 and through the center of the filling hole 2. In addition, the housing 3 carries the frame 14 for hinging the rod 15 of the actuator 16, the crane beam 17, which with the help of axis 18 is mounted on the longitudinal edge of the housing and can be rotated from the service position indicated by (Fig. 1) to connect its free axis 19 to the pivoting lever 20 moved by the actuator 16. This lever is hinged to the axle 8 and carries a spherical stake a spherical annular support 21, the ball ring 22 of which is an integral part of the clamping element 23, with which the pivot arm 20 is fixed on the trunnion 8 with the spring-elastic pressing of its rolling track 24 to the roller 11 and to the flap 26 fixed in the frame 25 to the bottom plate 6. At that, the flap frame 25 is mounted on the lever 20 with the possibility of movement around the cardan shaft 27.

    This characteristic of the spring acts on the axis 12 of the roller in the direction of the roller table 24. For easier control of the clamping element 23 with the tension of the swivel head calculated for operating conditions 20 and 20, the spherical ring 22 of the spherical bearing can be mounted on clamping element 23. As a bottom plate 6 and a flap plate 26, refractory plates with elliptical contour shape are used, which are held by ring 30. Plate 6 and plate 26 have two through holes Ersti a, B and
    30 At the bottom plate 6 on the small axis of the ellipse, at the plate 26 - on the major axis of the ellipse, so that after turning the bottom plate 6 by 180 ° in the plane of rotation, the former backup hole 6 begins to act as a pouring hole. The plate 6 and the plate 26 (Fig. 6) with the help of a crescent-shaped and rotated clamping box 4Q of the boat 31 due to the action of the control spindle 32 can be trapped in their grooves in the housing 3 or in frame 25. The frame 25 is above this equipped with an element 33 for connecting to the rod 15 of the actuator 16 and bayonet profiles 34 for connecting interchangeable drainage nozzles 35 to the valve plate 26 with replaceable sleeves 36.
    50 For changing the plate 6 and the plate 26, the following operations are performed: the drain nozzles 35 are removed, the stem 15 of the actuator 16 is moved and disconnected from the element 33 of the frame 25, the 55 of the elephants, the boom 17 is attached, the clamping element 23 is removed from the axle 8 , swivel the lever 20 back, replace the plate 6 and the plate 26, turn the lever 20, fit the element 45
    The characteristic spring characteristic that acts on the axis 12 of the roller in the direction of the roller table 24. For easier control of the clamping element 23 with the tension of the pivot arm 20 calculated according to the operating conditions, the spherical ring 22 of the spherical support can be installed with the aid of a rolling bearing on the clamping element 23. As a bottom plate 6 and a flap plate 26, refractory plates with an elliptical contour shape are used, which are held by a ring 30. Plate 6 and plate 26 have two through holes A, b and
