    WITH
    The invention relates to foundry and can be used to discharge and control metal from a metallurgical vessel.
    The aim of the invention is to increase reliability in operation.
    Figure 1 shows the shutter, section; figure 2 is the same, the coils are located in the fixed part of the shutter; fig.Z - the same, in the turning part of the shutter; figure 4 is the same, with the axial movement of the movable part of the shutter; figure 5 - shutter outside the tank; figure 6 - the same, inside the tank; 7 - the same, with a slit-like drain hole; in Fig.8 is a section aa in Fig.7.
    A metallurgical vessel with molten metal consists of a body with a bottom 1, a layer of lining 2 and a gate 3.
    The shutter 3 consists of a fixed refractory part - pipe 4 made of ceramic
    material located vertically (Fig.1-4) and secured in the bottom 1. Inside the container in the pipe are shed holes 5.
    A movable part 6 of ceramic material is installed on the pipe 4. The holes 7 are made around its circumference, the dimensions of which are the same as those of the holes 5. The movable part 6 can rotate around the axis of the pipe 4, so that in the open position of the gate 3 the axes of the holes 5 and 7 coincide, and in the closing position of the hole 4 are blocked movable part 6.
    The actuator 8 of the movable part 6 is electromagnetic, has one or more magnetic cores 9 in the form of a permanent magnet and one or more magnetic coils 10. Magnetic cores 9 are located in the movable part 6. Magnetic coils 10 are located at the bottom

    1, in it or in the pipe 4. Their connecting lines 1 are directed outwards.
    In the gate (FIG. 1), two magnetic cores 9 are embedded in the movable part b. However, with a distribution around the circumference there can be more than two. Each magnetic core 9 corresponds to a magnetic coil 10 located at the bottom 1 near the movable part 6. The magnetic coils 10 are located in a protective sheath 12 protecting them from melt.
    The design can be designed in such a way that, by appropriately loading the magnetic coils 10 with current, through the connecting lines 11, the movable part 6 rotates into the closed position in one direction and into the open position in the opposite direction. However, the movable part 6 can rotate only in one direction, since the closing position is respectively between two adjacent open positions, in which the axes of the openings 6 and 7 coincide.
    The magnetic coils 10 can be located in the pipe 4 (Fig. 2), due to which the protective sheath 12 and the gap between it and the movable part 6 become unnecessary.
    In FIG. 3, the movable part 6 is shown with a bent edge 13, in which magnetic cores 9 are placed, and the magnetic coils 10 are located here in the bottom 1. At the same time, they are protected by the edge 13 from melt.
    The movable part 6 can move in the axial direction at the position shown in Fig. 4, the openings 7 are blocked by the pipe 4. The holes 5 and 7 can be installed on one axis due to the rotation around the axis, when the movable part 6 is moved upwards. The tube 4 is concentric with respect to the axis, the additional magnetic coil 14.
    An additional magnetic core 15 in the form of a permanent magnet or a magnetizable iron core corresponds to this coil.
    If a current flows through the additional magnetic coil 14, the pipe rises so much that the holes 7 are located in the plane of the holes 5. When the polarity is reversed or the current is turned off, the moving part 6 moves down again. This occurs under the static pressure of the melt.
    The pipe 4 can be fixed outside the tank at the bottom of the bottom (figure 5). In this bottom, the movable part 6 having a radial hole 7 is mounted for movement and rotation. In the movable part 6
    the magnetic cores 9 are located, which correspond to the magnetic coils 10. Due to the corresponding current loading of the magnetic coils 10, the movable part 6 is rotated so that it blocks the apertures 5. An additional magnetic device is provided for axial movement of the movable part 6.
    0 The pipe 4 may be located down in the tank, and the movable part 6 is directed laterally to the outside. The latter is installed in the pipe 4 and has a bent channel as the hole 7, which, in the open position of the shutter, enters the hole 5 of the pipe 4 made in the form of an outlet channel.
    For a slit-like opening (Figures 7 and 8) for casting flat ingots, a pipe 4 is provided as
    0 a stator 16 forming an elongated slot 17. The stator 16 is divided into upper 18 and lower 19 parts. In the stator 16, a rotor 20 is mounted as a movable locking part, rotating in the stator 16 around a parallel bottom 1 of the axis. The rotor 20 has a hole 1, the flow cross section of which is equal to the flow cross section of the slot 17.
    In the lower part 19 of the stator 16 on the side of
    0 slit 17 is located on two magnetic coils 10, each of which corresponds to one magnetic core 9 located in the rotor 20.
    7 and 8, the shutter is shown in the open position. In addition, the opening 21 of the rotor 20 is located on the same axis with the slot 17. The rotor 20 is brought into this position by appropriate current flow through the magnetic coils 10. By changing the flow of current through the magnetic coils 10, the rotor 20 can be brought to a rotated position, in which the hole 21 is no longer on the same axis as the slot 17, and the rotor 20 overlaps the slot 17.
    5 Shutter metallurgical capacity works as follows.
    To drain the molten metal from the tank, the magnetic coils 10 supply current. Under the action of magnetic forces moving part
    0 6 is moved (rotated or shifted axially) and holes 5 and 7 are aligned. There is a release of metal from the tank. To close the gate, the current to the coils 10 and the moving part 6 are stopped.
    5 is moved back, blocking the openings 5 of the pipe 4,
    The magnetic coils 10 and 14 of the electromagnetic drive can be controlled in this way. When the movable part 6 is in the open or closed position, it
    is driven in a slow moving oscillating motion. In this way, the melt can be prevented from hardening in the zone of two surfaces, which must be movable relative to each other in order to bring the movable closure part from the closed position to the open position or vice versa.
    The use of this invention will improve the reliability of operation due to the possibility of remote control of the drive actuator.
