  • a closure of the type mentioned is also described in US-PS 3651998.
  • a drive element of the movable closure part provided below the vessel is passed through the immovable closure part.
  • the attachment of the drive element to the movable closure part and the implementation through the refractory closure part are problematic when sealing melt spouts.
  • EP-A-0251015 discloses a microvalve designed as a multi-way flat slide valve for liquid media with an electromagnetic drive, consisting exclusively of metallic parts with very small masses and dimensions, the manufacturing tolerances of which are in the range of a few thousandths Millimeters are known. Such a valve is completely unsuitable as a slide closure on the spout of a container containing molten metal, because its metallic valve parts could not withstand the thermal, chemical and mechanical stress caused by the molten metal.
  • the object of the invention is to propose a closure of the type mentioned at the outset which does not have the disadvantages listed above and whose drive elements are not passed through the melt or through a vessel wall.
  • the above object is achieved in that the rotary and / or lifting drive is designed as an electromagnetic drive which has at least one magnetic coil arranged in the immovable closure part or in a vessel wall and at least one magnetic core arranged in the movable closure part. It is thereby achieved that no physical drive element has to act on the movable closure part, which has to extend through the melt in the vessel or through the immovable closure part or the vessel wall. This eliminates the need for mechanical, hydraulic or pneumatic drives and the supply lines, drive elements and control elements connected to them.
  • the magnetic coil required for the electromagnetic drive is arranged on the vessel or on the closure part which is immovable relative to it. Your electrical connections can be connected easily and without special space requirements. It is possible to integrate the drive circuit into the electrical control circuit of the overall system.
  • the electromagnetic drive is not a hindrance.
  • the invention provides that the movable tube is at least opposite to the immovable tube by means of one arranged in the movable tube magnetic core and at least one arranged in the immovable tube and / or in the vessel wall solenoid is rotatable and / or displaceable, or that by means of the at least one solenoid the movable tube is rotatable about the axis of the immovable tube and by means of another magnet coil is displaceable in the axial direction of the immovable tube.
  • the immovable closure part is arranged outside the vessel and the movable closure part is mounted in it, according to the invention it is provided that the electromagnetic drive consists of at least one magnet coil arranged at the end of the immovable closure part and at least one on corresponding end of the movable closure member arranged magnetic core.
  • the electromagnetic drive according to the invention is arranged outside the vessel and consists of at least one magnet coil arranged on the outer end of the immovable closure part or on a side wall of the vessel and at least one magnet core arranged on the corresponding end of the movable closure part.
  • an electromagnetic drive acts on at least one of the two axial ends of the rotor according to the invention, wherein at least two magnetic cores are preferably arranged in the rotor and at least two magnetic coils assigned to the magnetic cores for rotating the rotor relative to the stator are arranged in the stator or in the vessel wall.
  • a closure (2) is arranged on the bottom (1) of a vessel for a molten metal.
  • the closure (2) according to FIGS. 1 to 4 has a refractory tube (3) made of ceramic material, the axis of which is perpendicular to the floor (1).
  • the tube (3) is fixed in the bottom (1). It is provided with two or more openings (4) within the vessel.
  • a further tube (5) made of ceramic material is attached to the tube (3) as a movable closure part.
  • the tube (5) is closed at the top. It is with its scope Provide openings (6) that are the same size as the openings (4).
  • the tube (5) can be rotated sealingly about the axis of the tube (3), so that the openings (4, 6) are aligned in the open position of the closure (2) and the openings (6) are covered by the tube (3) in the closed position are.

  • the associated magnetic coils (9) are arranged on or in the floor (1) or in the immovable closure part (3). Your connecting lines (10) are led to the outside.
  • a magnetic coil (9) is assigned to each magnetic core (8). This is arranged on the floor (1) close to the pipe (5). The magnetic coils (9) are each located in one or in a common protective jacket (11) which covers the magnetic coils (9) against the melt.
  • the arrangement can be designed in such a way that the tube (5) is rotated in the closed position in one direction and in the open position in the opposite direction by a corresponding current application to the magnetic coils (9) via the connecting lines (10).
  • the tube (5) is only rotated in one direction. Because a closed position lies between two adjacent open positions, in which the openings (4, 6) are aligned.
  • the exemplary embodiment according to FIG. 2 differs from the exemplary embodiment according to FIG. 1 in that the magnetic coils (9) are not arranged outside the tube (5) on the bottom (1) but are integrated in the tube (3). This eliminates the need for the protective jacket (11) and eliminates the necessary gap (12) between the protective jacket (11) and the pipe (5).
  • an angled edge (13) is formed on the tube (5).
  • the magnetic cores (8) are integrated in these.
  • the magnetic coils (9) are integrated in the base (1) here. They are covered by the edge (13) against the melt.
  • the mode of operation of the embodiment according to FIGS. 2 and 3 corresponds to that of the embodiment according to FIG. 1.
  • the tube (5) is not only rotatable about the axis, but also axially displaceable.
  • the openings (6) are closed by the tube (3). So you are not in alignment with its openings (4).
