Description

Die Erfindung betrifft einen Dreh- und/oder Schieberschluß für einen Ausguß eines Metallschmelze enthaltenden Gefäßes mit einem feuerfesten, unbeweglichen Verschlußteil und einem relativ zu diesem dichtend dreh- und/oder verschiebbaren, feuerfesten, beweglichen Verschlußteil, das mittels eines Dreh- und/oder Hubantriebs betägtigbar ist. Weiterhin betrifft die Erfindung die Verschlußteile eines solchen Dreh- und/oder Schieberverschlusses.The invention relates to a rotary and / or slide closure for a pouring of a metal-containing vessel with a refractory, immovable closure part and a relative to this sealingly rotatable and / or displaceable, refractory, movable closure part, which by means of a rotary and / or lifting drive is actuatable. Furthermore, the invention relates to the closure parts of such a rotary and / or slide closure.

Bekannt sind mechanische, hydraulische oder pneumatische Antriebe. Derartige Antriebe sind konstruktiv aufwendig und platzraubend. Sie sind außerdem in der Regel wenig bedienungsfreundlich und erfordern eine Vielzahl von Zuleitungen, beispielsweise für Druckluft oder Hydrauliköl, sowohl für den Antrieb selbst als auch für dessen Steuerorgane. Hieraus ergibt sich eine sehr aufwendige Instandhaltung. Es ist auch meist schwierig, den Dreh- und/oder Schieberverschluß zur Erneuerung verschlissener Feuerfestteile zu handhaben. Denn hierfür sind in der Regel die Antriebselemente abzukoppeln.Mechanical, hydraulic or pneumatic drives are known. Such drives are structurally complex and space-consuming. They are also generally not very user-friendly and require a large number of supply lines, for example for compressed air or hydraulic oil, both for the drive itself and for its control elements. This results in very complex maintenance. It is also usually difficult to handle the twist and / or slide lock to replace worn refractory parts. This is because the drive elements must be uncoupled as a rule.

In der äteren Patentanmeldung P 37 31 600 ist ein Dreh- und Schieberverschluß der eingangs genannten Art beschrieben. Bei einer ersten Ausführung ist der Verschluß außen am Gefäß angeordnet (Außensystem). Bei einer zweiten Ausführung ist der Verschluß in dem Gefäß angeordnet, wobei das bewegliche Verschlußteil nach außen geführt ist (Innensystem mit Außenantrieb).In the earlier patent application P 37 31 600 a rotary and slide closure of the type mentioned is described. In a first embodiment, the closure is arranged on the outside of the vessel (external system). In a second embodiment, the closure is arranged in the vessel, the movable closure part being guided outwards (internal system with external drive).

Ein weiterer im Gefäß liegender Verschluß der eingangs genannten Art ist in der DE-PS 35 40 202 beschrieben. Bei dem Verschluß der DE-PS 35 40 202 ist an dem beweglichen Verschlußteil eine Führungsstange befestigt, die durch die Schmelze hindurch nach oben geführt ist. Dies bedingt eine aufwendige Feuerfestisolierung bzw. Abdichtung der Antriebselemente.Another closure in the vessel of the type mentioned is described in DE-PS 35 40 202. In the closure of DE-PS 35 40 202, a guide rod is attached to the movable closure part, which is guided through the melt upwards. This requires complex refractory insulation or sealing of the drive elements.

Ein Verschluß der eingangs genannten Art ist auch in der US-PS 3 651 998 beschrieben. Bei diesem ist ein unterhalb des Gefäßes vorgesehenes Antriebselement des bewegliches Verschlußteiles durch das unbewegliche Verschlußteil hindurchgeführt. Die Befestigung des Antriebselements am beweglichen Verschlußteil und die Durchführung durch das feuerfeste Verschlußteil sind bei Verschlüssen von Schmelzenausgüssen problematisch.A closure of the type mentioned is also described in US Pat. No. 3,651,998. In this case, 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.

Aufgabe der Erfindung ist es, einen Verschluß der eingangs genannten Art vorzuschlagen, der die auf Seite 1, Absatz 2 aufgeführten Nachteile nicht aufweist und dessen Antriebselemente weder durch die Schmelze noch durch eine Gefäßwand hindurchgeführt sind.The object of the invention is to propose a closure of the type mentioned, which does not have the disadvantages listed on page 1, paragraph 2 and whose drive elements are neither passed through the melt nor through a vessel wall.

Erfindungsgemäß ist obige Aufgabe dadurch gelöst, daß der Dreh- und/oder Hubantrieb als elektromagnetischer Antrieb ausgebildet ist. Dadurch ist erreicht, daß an dem beweglichen Verschlußteil kein körperliches Antriebselement angreifen muß, daß sich durch die Schmelze im Gefäß oder durch das unbewegliche Verschlußteil bzw. die Gefäßwand erstrecken muß. Es erübrigen sich damit mechanische, hydraulische oder pneumatische Antriebe und die mit diesen verbundenen Zuleitungen, Antriebselemente und Steuerorgane. Eine für den elektromagnetischen Antrieb nötige Magnetspule ist am Gefäß oder am diesem gegenüber unbeweglichen Verschlußteil angeordnet. Ihre elektrischen Anschlüsse lassen sich damit einfach und ohne besonderen Platzbedarf anschließen. Hierbei ist es möglich, den Stromkreis des Antriebes in den elektrischen Steuerkreis der Gesamtanlage zu integrieren.According to the invention, the above object is achieved in that the rotary and / or lifting drive is designed as an electromagnetic drive. It is thereby achieved that no physical drive element has to act on the movable closure part, that it must 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. A 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.

Bei einer zu Wartungszwecken nötigen Trennung des beweglichen Verschlußteils vom unbeweglichen Verschlußteil stellt der elektromagnetische Antrieb keine Behinderung dar.If the movable closure part is separated from the immovable closure part for maintenance purposes, the electromagnetic drive is not a hindrance.

In bevorzugter Ausgestaltung der Erfindung ist ein Magnetkern des elektromagnetischen Antriebs im beweglichen Verschlußteil integriert. Eine Magentspule des elektromagnetischen Antriebs ist dann im beweglichen Verschlußteil oder in der Gefäßwandung integriert.In a preferred embodiment of the invention, a magnetic core of the electromagnetic drive is integrated in the movable closure part. A magnetic coil of the electromagnetic drive is then integrated in the movable closure part or in the vessel wall.

Am Boden (1) eines Gefäßes für eine Metallschmelze ist ein Verschluß (2) angeordnet.A closure (2) is arranged on the bottom (1) of a vessel for a molten metal.

Der Verschluß (2) nach den Figuren 1 bis 4 weist als unbewegliches Verschlußteil ein feuerfestes Rohr (3) aus keramischem Material auf, dessen Achse senkrecht zum Boden (1) steht. Das Rohr (3) ist im Boden (1) befestigt. Innerhalb des Gefäßes ist es mit zwei oder mehreren Durchbrechungen (4) versehen. Auf das Rohr (3) ist als bewegliches Verschlußteil ein weiteres Rohr (5) aus keramischem Material aufgesteckt. Das Rohr (5) ist oben geschlossen. An seinem Umfang ist es mit Durchbrechungen (6) versehen, die ebenso groß sind wie die Durchbrechungen (4). Das Rohr (5) ist um die Achse des Rohres (3) dichtend drehbar, so daß in der Öffnungsstellung des Verschlusses (2) die Durchbrechungen (4, 6) fluchten und in der Schließstellung die Durchbrechungen (6) vom Rohr (3) abgedeckt sind.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. Another 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 in a sealing manner around 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.

Als Drehantrieb für das Rohr (5) ist ein elektromagnetischer Antrieb (7) vorgesehen. Dieser weist einen oder mehrere permanentmagnetische Magnetkerne (8) und eine oder mehrere Magnetspulen (9) auf. Der bzw. die Magnetkerne (8) sind in dem beweglichen Verschlußteil (5) angeordnet. Die zugehörigen Magnetspulen (9) sind am oder im Boden (1) oder im unbeweglichen Verschlußteil (3) angeordnet. Ihre Anschlußleitungen (10) sind nach außen geführt.An electromagnetic drive (7) is provided as the rotary drive for the tube (5). This has one or more permanent magnetic magnetic cores (8) and one or more magnetic coils (9). The magnetic core (s) (8) are arranged in the movable closure part (5). 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.

Beim Ausführungsbeispiel nach Figur 1 sind in das Rohr (5) zwei Magnetkerne (8) eingebaut. Es können jedoch auch mehr als zwei Magnetkerne (8) am Umfang verteilt angeordnet sein. Im Prinzip kann auch ein Magnetkern genügen. Jedem Magnetkern (8) ist eine Magnetspule (9) zugeordnet. Diese ist am Boden (1) dicht neben dem Rohr (5) angeordnet. Die Magnetspulen (9) sitzen jeweils in einem oder in einem gemeinsamen Schutzmantel (11), der die Magnetspulen (9) gegen die Schmelze abdeckt.In the embodiment of Figure 1, two magnetic cores (8) are installed in the tube (5). However, more than two magnetic cores (8) can also be distributed around the circumference. In principle, a magnetic core can also suffice. 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.

Die Anordnung kann so gestaltet sein, daß durch eine entsprechende Strombeaufschlagung der Magnetspulen (9) über die Anschlußleitungen (10) das Rohr (5) in Schließstellung in die eine Richtung und in Öffnungsstellung in die Gegenrichtung gedreht wird.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).

Es kann jedoch auch vorgesehen sein, das Rohr (5) nur in einer Richtung zu drehen. Denn eine Schließstellung liegt jeweils zwischen zwei benachbarten Öffnungsstellungen, in denen die Durchbrechnungen (4, 6) fluchten.However, it can also be provided that 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.

Das Ausführungsbeispiel nach Figur 2 unterscheidet sich vom Ausführungsbeispiel nach Figur 1 dadurch, daß die Magnetspulen (9) nicht außerhalb des Rohres (5) am Boden (1) angeordnet, sondern in dem Rohr (3) integriert sind. Dadurch erübrigt sich der Schutzmantel (11) und es entfällt der notwendige Spalt (12) zwischen dem Schutzmantel (11) und dem Rohr (5).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).

Beim Ausführungsbeispiel nach Fig. 3 ist an dem Rohr (5) ein abgewinkelter Rand (13) ausgebildet. In diesen sind die Magnetkerne (8) integriert. Die Magnetspulen (9) sind hier in den Boden (1) integriert. Sie sind dabei durch den Rand (13) gegen die Schmelze abgedeckt.3, 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.

Die Funktionsweise der Ausführung nach den Figuren 2 und 3 entspricht der des Ausführungsbeispiels nach Figur 1.The mode of operation of the embodiment according to FIGS. 2 and 3 corresponds to that of the embodiment according to FIG. 1.

Beim Ausführungsbeispiel nach Figur 4 ist das Rohr (5) nicht nur um die Achse drehbar, sondern auch axial verschieblich. In der in Figur 4 dargestellten Stellung sind die Durchbrechungen (6) vom Rohr (3) geschlossen. Sie fluchtend also nicht mit dessen Durchbrechungen (4). Die Durchbrechungen (4, 6) lassen sich durch Drehen um die Achse erst dann fluchtend ausrichten, wenn das Rohr (5) nach oben bewegt ist. Hierfür ist eine zur genannten Achse konzentrische weitere Magnetspule (14) im Rohr (3) angeordnet.In the embodiment of Figure 4, the tube (5) is not only rotatable about the axis, but also axially displaceable. In the position shown in Figure 4, the openings (6) are closed by the tube (3). So you are not in alignment with its openings (4). The openings (4, 6) can only be aligned by turning around the axis when the tube (5) is moved upwards. For this purpose, a further magnetic coil (14) is arranged in the tube (3) which is concentric with the axis mentioned.

Dieser ist ein weiterer permanentmagnetischer Magnetkern (15) oder ein magnetisierbarer Eisenkern zugeordnet, der in dem Rohr (5) integriert ist. Die weitere Magnetspule (14) könnte auch in dem Boden (1) integriert sein.This is assigned a further permanent magnetic core (15) or a magnetizable iron core, which is integrated in the tube (5). The further magnetic coil (14) could also be integrated in the base (1).

Ist die weitere Magnetspule (14) stromdurchflossen, dann wird das Rohr (5) so angehoben, daß Durchbrechungen (6) in der Ebene der Durchbrechungen (4) liegen. Beim Umpolen bzw. Abschalten des Stroms durch die Magnetspule (14) wird das Rohr (5) wieder nach unten bewegt. Dies geschieht dann, wenn ein Eisenkern (15) vorgesehen ist unter dem statischen Druck der Schmelze.If the further magnetic coil (14) has current flowing through it, the tube (5) is raised so that openings (6) lie in the plane of the openings (4). When the polarity is reversed or the current is switched off by the magnetic coil (14), the tube (5) is moved down again. This happens when an iron core (15) is provided under the static pressure of the melt.

Zum Drehen des Rohres (5) sind die beschriebenen Magnetkerne (8) und die Magnetspulen (9) vorgesehen.The described magnetic cores (8) and the magnetic coils (9) are provided for rotating the tube (5).

Beim Ausführungsbeispiel nach Figur 5 ist das unbewegliche Verschlußteil (3) außerhalb des Gefäßes unten am Boden (1) befestigt. In diesem ist verschieblich und drehbar das bewegliche Verschlußteil (5) gelagert, das eine radiale Durchbrechung (6) aufweist, welche in der Offenstellung mit radialen Durchbrechungen (4) fluchtet. In dem beweglichen Verschlußteil (5) sind Magnetkerne (8) integriert, denen Magnetspulen (9) zugeordnet sind. Durch eine entsprechende Strombeaufschlagung der Magnetspulen (9) wird das bewegliche Verschlußteil (5) so gedreht, daß es die Durchbrechungen (4) schließt. Eine weitere Magnetanordnung kann zur axialen Verschiebung des beweglichen Verschlußteils (5) vorgesehen sein.In the exemplary embodiment according to FIG. 5, the immovable closure part (3) is fastened to the bottom (1) outside of the vessel. The movable closure part (5), which has a radial opening (6) and is aligned with radial openings (4) in the open position, is mounted displaceably and rotatably. Magnetic cores (8), to which magnetic coils (9) are assigned, are integrated in the movable closure part (5). The movable closure part (5) is rotated by a corresponding current application of the magnetic coils (9) in such a way that it closes the openings (4). A further magnet arrangement can be provided for the axial displacement of the movable closure part (5).

Beim Ausführungsbeispiel nach Figur 6 ist das unbewegliche Verschlußteil (3) unten im Gefäß angeordnet und das bewegliche Verschlußteil (5) seitlich nach außen geführt. Letzteres ist im unbeweglichen Verschlußteil (3) gelagert und weist als Durchbrechung (6) einen abgewinkelten Kanal auf, welcher in Offenstellung des Verschlusses in eine als Auslaufkanal ausgebildete Durchbrechung (4) des unbeweglichen Verschlußteils (3) mündet. Zum Drehantrieb des beweglichen Verschlußteils (5) sind außerhalb des Gefäßes die Magnetspulen (9) vorgesehen, denen im beweglichen Verschlußteil (5) integrierte Magnetkerne (8) zugeordnet sind.In the embodiment according to FIG. 6, the immovable closure part (3) is arranged at the bottom in the vessel and the movable closure part (5) is guided laterally outwards. The latter is mounted in the immovable closure part (3) and, as the opening (6), has an angled channel which, when the closure is open, opens into an opening (4) in the immovable closure part (3) designed as an outlet channel. The magnetic coils (9), to which magnetic cores (8) integrated in the movable closure part (5) are assigned, are provided outside the vessel for rotating the movable closure part (5).

Beim Ausführungsbeispiel nach den Figuren 7 und 8 ist der Verschluß (2) für einen langgestreckten Ausguß am Boden (1) eines Metallschmelze enthaltenden Gefäßes vorgesehen, der zum Gießen von Dünnbrammen geeignet ist. Als unbewegliches Verschlußteil ist ein Stator (17) vorgesehen, der einen langgestreckten Schlitz (10) bildet. Der Stator (17) ist in ein Oberteil (19) und ein Unterteil (20) geteilt. In dem Stator (17) ist ein Rotor (21) als bewegliches Verschlußteil gelagert. Der Rotor (21) ist um eine zum boden (1) parallele Achse im Stator (17) drehbar. Er weist eine Durchbrechung (22) auf, deren Durchlaßquerschnitt dem Durchlaßquerschnitt des Schlitzes (18) gleich ist.In the exemplary embodiment according to FIGS. 7 and 8, the closure (2) is provided for an elongated spout at the bottom (1) of a vessel containing molten metal, which is suitable for casting thin slabs. A stator (17) is provided as an immovable closure part and forms an elongated slot (10). The stator (17) is divided into an upper part (19) and a lower part (20). A rotor (21) is mounted in the stator (17) as a movable closure part. The rotor (21) can be rotated about an axis parallel to the base (1) in the stator (17). It has an opening (22), the passage cross section of which is the same as the passage cross section of the slot (18).

In dem Unterteil (20) des Stators (17) sind seitlich des Schlitzes (18) je zwei Magnetspulen (9) angeordnet, denen je ein Magnetkern (8) zugeordnet ist. Die Magnetkerne (8) sind in den Rotor (21) integriert.In the lower part (20) of the stator (17) two magnet coils (9) are arranged to the side of the slot (18), each of which a magnetic core (8) is assigned. The magnetic cores (8) are integrated in the rotor (21).

In den Figuren 7 und 8 ist der Rotor (21) in Offenstellung dargestellt. Seine Durchbrechung (22) fluchtet dabei mit dem Schlitz (18). Der Rotor (21) ist durch einen entsprechenden Stromfluß durch die Magnetspulen (9) in diese Stellung gebracht. Durch eine Änderung des Stromflusses durch die Magnetspulen (9) läßt sich der Rotor (21) in eine Verdrehstellung bringen, in der die Durchbrechung (22) nicht mehr mit dem Schlitz (18) fluchtet und der Rotor (21) den Schlitz (18) schließt.In Figures 7 and 8, the rotor (21) is shown in the open position. Its opening (22) is aligned with the slot (18). The rotor (21) is brought into this position by a corresponding current flow through the magnet coils (9). By changing the current flow through the magnetic coils (9), the rotor (21) can be brought into a rotational position in which the opening (22) is no longer aligned with the slot (18) and the rotor (21) slits the slot (18). closes.

Bei dem Ausführungsbeispiel nach Figur 7 und 8 kann der Rotor (21) auch so verlängert sein, daß er in Richtung seiner Drehachse seitlich über das Gefäß hinaussteht. Es ist dann möglich, den beschriebenen elektromagnetischen Antrieb außerhalb des Gefäßes anzuordnen.In the exemplary embodiment according to FIGS. 7 and 8, the rotor (21) can also be extended such that it projects laterally beyond the vessel in the direction of its axis of rotation. It is then possible to arrange the electromagnetic drive described outside the vessel.

Die Magnetspulen (9 bzw. 14) des elektromagnetischen Antriebs können auch so angesteuert werden, daß dann, wenn das bewegliche Verschlußteil (5 bzw. 20) in seiner Öffnungsstellung oder in seiner Schließstellung steht, es in eine mit einem geringen Hub oszillierende Bewegung versetzt wird. Dadurch kann das Erstarren der Schmelze im Bereich zweier Flächen, die gegeneinander beweglich sein sollen, um das bewegliche Verschlußteil von seiner Schließstellung in seine Öffnungsstellung oder umgekehrt zu bringen, verhindert werden.The magnetic coils (9 or 14) of the electromagnetic drive can also be controlled so that when the movable closure part (5 or 20) is in its open position or in its closed position, it is set into an oscillating movement with a small stroke . As a result, the solidification of the melt can be prevented in the region of two surfaces which are to be movable relative to one another in order to bring the movable closure part from its closed position into its open position or vice versa.
