Description

Die vorliegende Erfindung betrifft eine Kokillenwand einer Stranggießkokille, die aus einer Kokilleninnenplatte und einem mit der Kokilleninnenplatte über Schraubverbindungen verbundenen Wasserkasten besteht, wobei die Kokilleninnenplatte auf ihrer dem Wasserkasten zugewandten Seite Stege mit dazwischen verlaufenden Nuten mit einer Nutbreite aufweist, in denen Füllstücke angeordnet sind.The present invention relates to a mold wall Continuous casting mold consisting of an inner mold plate and a connected to the inner mold plate via screw connections There is a water tank, the inner mold plate on their side facing the water tank, there are webs in between has extending grooves with a groove width in which Filling pieces are arranged.

Eine derartige Kokillenwand ist allgemein bekannt. Die Nuten dienen dabei als Kühlkanäle für eine Kühlflüssigkeit, in der Regel Wasser. Die Füllstücke dienen der Verringerung des Kanalquerschnitts, so daß sich die Fließgeschwindigkeit der Kühlflüssigkeit im Kühlkanal erhöht. Sie haben aber keine Tragfunktion. Die Befestigung der Kokilleninnenwand mit dem Wasserkasten erfolgt über eine Vielzahl von Schrauben, welche den Wasserkasten zumindest teilweise durchdringen und die in Gewindestücke eingeschraubt sind, welche in der Kokilleninnenwand angeordnet sind.Such a mold wall is generally known. The grooves serve as cooling channels for a coolant in the Rule water. The fillers serve to reduce the channel cross-section, so that the flow rate of the Coolant in the cooling channel increased. But you don't have any Supporting function. The attachment of the inner mold wall with the Water box is made using a variety of screws, which at least partially penetrate the water tank and the in Threaded pieces are screwed into the inner wall of the mold are arranged.

Die Kokillenwand des Standes der Technik weist mehrere Nachteile auf. Insbesondere ist das Einbringen der Gewindestücke in die Kokilleninnenplatte sehr aufwendig. Ferner besteht die Kokilleninnenplatte in der Regel aus Kupfer, wogegen die Gewindestücke aus Stahl sind. Bei einem Austausch einer verschlissenen Kokilleninnenplatte fällt somit eine große Menge verunreinigten Kupfers an, welches nur umständlich einer Wiederverwertung zugeführt werden kann. The prior art mold wall has several disadvantages on. In particular, the introduction of the threaded pieces very expensive in the mold inner plate. Furthermore, there is The inner mold plate is usually made of copper, whereas the threaded pieces are made of steel. When replacing a worn one The inner mold plate thus falls a large amount contaminated copper, which is difficult to recycle can be supplied.

Die Aufgabe der vorliegenden Erfindung besteht darin, eine Kokillenwand einer Stranggießkokille zu schaffen, welche die Nachteile des Standes der Technik vermeidet.The object of the present invention is a To create the mold wall of a continuous casting mold, which the Avoids disadvantages of the prior art.

Die Aufgabe wird dadurch gelöst, daß

  • daß die Nuten Hinterschneidungen mit einer Hinterschneidungsdicke aufweisen,
  • daß die Füllstücke Verbindungselemente mit einer Verbindungselementdicke aufweisen,
  • daß die Füllstücke lösbar in die Hinterschneidungen eingreifen, und
  • daß die Schraubverbindungen zwischen den Füllstücken zu dem Wasserkasten angeordnet sind.
The problem is solved in that
  • that the grooves have undercuts with an undercut thickness,
  • that the filler pieces have connecting elements with a connecting element thickness,
  • that the filler pieces releasably engage in the undercuts, and
  • that the screw connections between the filler pieces are arranged to the water tank.

Denn aufgrund dieser Ausgestaltung der Kokillenwand muß das Verschleißteil Kokilleninnenplatte nur die Stege zur Bildung der Kühlkanäle aufweisen. Eine weitergehende Bearbeitung der Kokilleninnenplatte, insbesondere das Einbringen von Schraubverbindungen in die Kokilleninnenplatte, ist nicht erforderlich. Bei der Demontage des Verschleißteils

Kokilleninnenplatte" erfolgt beim Lösen der Verbindungselemente eine automatische Trennung der kupfernen Kokilleninnenplatte von den Stahlteilen. Die Kokilleninnenplatte ist also leichter wiederverwertbar.Because due to this configuration of the mold wall, the wearing part of the mold inner plate only has to have the webs for forming the cooling channels. Further processing of the inner mold plate, in particular the introduction of screw connections into the inner mold plate, is not necessary. When dismantling the wearing part
Figure 00020001
When the connecting elements are loosened, the inner mold plate automatically separates the inner copper plate from the steel parts. The inner mold plate is therefore easier to recycle.

Wenn die Verbindungselementdicke kleiner als die Hinterschneidungsdicke ist, sind die Verbindungselemente besonders leicht in die Hinterschneidungen einführbar.If the fastener thickness is less than the undercut thickness the connecting elements are special easy to insert into the undercuts.

Wenn die Verbindungselemente und/oder die Hinterschneidungen konisch ausgebildet sind, sind die Verbindungselemente spielfrei in die Hinterschneidungen einführbar.If the fasteners and / or the undercuts are conical, the connecting elements are free of play insertable into the undercuts.

Wenn die Verbindungselemente aus den Füllstücken ausfahrbar sind, sind die Füllstücke besonders einfach mit den Nuten verbindbar. When the connecting elements extendable from the filler pieces the filler pieces are particularly easy with the grooves connectable.

Die lösbare Befestigung der Füllstücke in den Nuten kann beispielsweise dadurch bewirkt werden,

  • daß die Verbindungselemente um Schwenkachsen schwenkbare Schwenkelemente aufweisen,
  • daß die Schwenkelemente in senkrecht auf den Schwenkachsen stehenden Schwenkebenen eine maximale Länge und eine maximale Breite aufweisen,
  • daß die maximale Länge größer als die Nutbreite ist und
  • daß die maximale Breite maximal so groß wie die Nutbreite ist.
The detachable fastening of the filler pieces in the grooves can be effected, for example, by
  • that the connecting elements have pivoting elements pivotable about pivot axes,
  • that the swivel elements have a maximum length and a maximum width in swivel planes which are perpendicular to the swivel axes,
  • that the maximum length is greater than the groove width and
  • that the maximum width is as large as the groove width.

Bei einer derartigen Ausgestaltung können die Schwenkelemente in der Schwenkebene beispielsweise einen rechteckigen, einen elliptischen oder einen ovalen Querschnitt aufweisen.With such a configuration, the pivot elements in the swivel plane, for example, a rectangular one have an elliptical or oval cross section.

Alternativ zur Verwendung von Schwenkelementen ist es auch möglich, daß die Verbindungselemente Spreizplatten aufweisen, die mittels Schrauben in die Hinterschneidungen ausfahrbar sind.It is also an alternative to using swivel elements possible that the connecting elements have spreading plates, which can be extended into the undercuts by means of screws are.

Das Spreizen der Spreizplatten kann beispielsweise mittels konisch zulaufender Spreizscheiben erfolgen, die zwischen den Schrauben und den Spreizplatten angeordnet sind. Alternativ oder zusätzlich können die Schrauben zumindest in einem Teilabschnitt konisch verjüngt ausgebildet sein.The spreading plates can be spread, for example, by means of conical spreading disks are made between the Screws and the expansion plates are arranged. Alternatively or in addition, the screws can at least in one section be conically tapered.

Wenn den Verbindungselementen Federelemente zugeordnet sind, ist auch bei einer Erwärmung der Kokillenwand ein Aufrechterhalten einer formschlüssigen Verbindung zwischen den Füllstücken und den Stegen gewährleistet.If spring elements are assigned to the connecting elements, is maintained even when the mold wall is heated a positive connection between the filler pieces and the ridges guaranteed.

Gemäß Figur 1 besteht eine Kokillenwand einer Stranggießkokille aus einer Kokilleninnenplatte 1 und einem Wasserkasten 2. Die Kokilleninnenplatte 1 weist eine Innenseite 3 und eine Außenseite 4 auf. Die Außenseite 4 ist im Betrieb der Stranggießkokille dem zu gießenden flüssigen Metall, insbesondere Stahl, zugewandt. Die Innenseite 3 hingegen ist dem Wasserkasten 2 zugewandt. Die Kokilleninnenplatte 1 ist mit dem Wasserkasten 2 über Schraubverbindungen verbunden. Die Schraubverbindungen sind in Figur 1 durch die gestrichelten Linien angedeutet.According to Figure 1 there is a mold wall of a continuous casting mold from an inner mold plate 1 and a water tank 2. The inner mold plate 1 has an inner side 3 and one Outside 4 on. The outside 4 is in operation of the continuous casting mold the liquid metal to be cast, in particular Steel, facing. The inside 3, however, is the water tank 2 facing. The inner mold plate 1 is with the water tank 2 connected via screw connections. The screw connections are in Figure 1 by the dashed lines indicated.

Auf ihrer Innenseite 3 weist die Kokilleninnenplatte 1 senkrecht verlaufende Stege 5 auf. Zwischen den Stegen 5 verlaufen demzufolge Nuten 6 mit einer Nutbreite a. Wie besonders deutlich aus Figur 2 ersichtlich ist, weisen die Nuten 6 Hinterschneidungen 6' mit einer Hinterschneidungsdicke b auf. In den Nuten 6 sind Füllstücke 7 angeordnet. An den Füllstücken 7 sind Gewindebolzen 8 angeschweißt, mittels derer die Füllstücke 7 und somit auch die Kokilleninnenplatte 1 mit dem Wasserkasten 2 verschraubt sind. Die Schraubverbindungen zwischen der Kokilleninnenplatte 1 und dem Wasserkasten 2 sind also zwischen den Füllstücken 7 und dem Wasserkasten 2 angeordnet. On its inside 3, the inner mold plate 1 faces vertically extending webs 5. Run between the webs 5 consequently grooves 6 with a groove width a. How special can be clearly seen from Figure 2, the grooves 6 have undercuts 6 'with an undercut thickness b. In the grooves 6, filler pieces 7 are arranged. On the fillers 7 threaded bolts 8 are welded, by means of which the filler pieces 7 and thus also the inner mold plate 1 with the Water box 2 are screwed. The screw connections between the inner mold plate 1 and the water tank 2 are thus arranged between the filler pieces 7 and the water tank 2.

Die Verbindung zwischen den Füllstücken 7 und der Kokilleninnenplatte ist aus den Figuren 3 und 4 ersichtlich. Gemäß den Figuren 3 und 4 weisen die Füllstücke 7 Verbindungselemente 9 auf. Die Verbindungselemente 9 weisen eine Verbindungselementdicke c auf. Die Verbindungselemente 9 greifen mit Schwenkelementen 10 lösbar in die Hinterschneidungen 6' ein. Die Schwenkelemente 10 sind um Schwenkachsen 11 schwenkbar. In senkrecht auf den Schwenkachsen 11 stehenden Schwenkebenen 12 weisen die Schwenkelemente 10 eine maximale Länge d und eine maximale Breite e auf. Die maximale Länge d ist größer als die Nutbreite a. Die maximale Breite e ist gemäß Ausführungsbeispiel kleiner als die Nutbreite a. Sie könnte aber auch so groß wie die Nutbreite a sein.The connection between the filler pieces 7 and the inner mold plate can be seen from Figures 3 and 4. According to the FIGS. 3 and 4 have the filling pieces 7 connecting elements 9 on. The connecting elements 9 have a connecting element thickness c on. The connecting elements 9 engage Swivel elements 10 releasably into the undercuts 6 '. The pivot elements 10 are pivotable about pivot axes 11. In swivel planes standing perpendicular to the swivel axes 11 12, the pivot elements 10 have a maximum length d and a maximum width e. The maximum length d is greater than the groove width a. The maximum width e is according to the embodiment smaller than the groove width a. But it could also be as large as the groove width a.

Durch Verschwenken der Schwenkelemente 10 in ihrer Schwenkebene 12 sind die Verbindungselemente 9 aus den Füllstücken 7 ausfahrbar. Die Verbindungselemente 9 greifen hierdurch lösbar in die Hinterschneidungen 6' ein. Die Füllstücke 7 sind somit formschlüssig mit der Kokilleninnenplatte 1 verbindbar.By pivoting the pivot elements 10 in their pivot plane 12 are the connecting elements 9 from the filler pieces 7 extendable. The connecting elements 9 thereby releasably engage in the undercuts 6 '. The fillers 7 are can thus be positively connected to the inner mold plate 1.

Gemäß Figur 4 weisen die Schwenkelemente 10 in der Schwenkebene 12 einen rechteckigen Querschnitt auf. Der Querschnitt kann aber auch anders gestaltet sein, z. B. elliptisch oder oval. Ferner ist die Verbindungselementdicke c kleiner als die Hinterschneidungsdicke b. Hierdurch sind die Schwenkelemente 10 besonders leicht in die Hinterschneidungen 6' einführbar. Alternativ könnten die Verbindungselemente 9 und/oder die Hinterschneidungen 6' auch konisch ausgebildet sein.According to Figure 4, the pivot elements 10 have in the pivot plane 12 has a rectangular cross section. The cross section but can also be designed differently, e.g. B. elliptical or oval. Furthermore, the connecting element thickness c is less than the undercut thickness b. As a result, the swivel elements 10 particularly easy to insert into the undercuts 6 '. Alternatively, the connecting elements 9 and / or the undercuts 6 'are also conical his.

Alternativ zur Ausbildung der Verbindungselemente 9 mit Schwenkelementen 10 können die Verbindungselemente 9 gemäß Figur 5 auch konisch zulaufende Spreizplatten 13 aufweisen. Die Spreizplatten 13 sind mittels Schrauben 14 in die Hinterschneidungen 6' ausfahrbar. Das Ausfahren der Spreizplatten 13 kann dabei, wie in Figur 5 dargestellt, dadurch erfolgen, daß zwischen den Schrauben 14 konisch zulaufende Spreizscheiben 15 angeordnet sind. Alternativ oder zusätzlich könnten die Schrauben 14 auch - zumindest in einem Teilabschnitt - konisch verjüngt ausgebildet sein.As an alternative to forming the connecting elements 9 with The connecting elements 9 can be pivoted according to FIG Figure 5 also have tapered expansion plates 13. The spreading plates 13 are by means of screws 14 in the undercuts 6 'extendable. Extending the spreading plates 13, as shown in FIG. 5, can be done by that between the screws 14 tapered spreading washers 15 are arranged. Alternatively or in addition the screws 14 also - at least in one section - be conically tapered.

Um zugewährleisten, daß die formschlüssige Verbindung zwischen den Stegen 5 und und den Füllstücken 7 auch bei einer Erwärmung der Kokillenwand sicher aufrechterhalten bleibt, sind den Verbindungselementen 9 gemäß den Figuren 5 und 6 Federelemente 16 zugeordnet. Gemäß Ausführungsbeispiel sind die Federelemente 16 als O-Ringe aus einem dauerelastischen Material ausgebildet, welches den beim Stranggießen auftretenden Temperaturen widersteht und eine hinreichende Dicke aufweist.To ensure that the positive connection between the webs 5 and and the filler pieces 7 also at one Heating of the mold wall is safely maintained, are the connecting elements 9 according to Figures 5 and 6 spring elements 16 assigned. According to the embodiment, the Spring elements 16 as O-rings made of a permanently elastic material trained, which occurs during continuous casting Resists temperatures and has a sufficient thickness.

Mit der erfindungsgemäßen Kokillenwand ist eine Vielzahl von Vorteilen erreichbar. Beispielsweise sind keine Bohrungen auf der Rückseite der Kokilleninnenplatte 1 erforderlich. Ferner müssen keine Gewindeeinsätze in die Kokilleninnenplatte 1 eingesetzt werden. Die Nuten 6, die als Kühlkanäle dienen, können einen gleichmäßigen Abstand voneinander aufweisen. Für verbrauchte Kokilleninnenplatten 1 kann ein höherer Schrotterlös erzielt werden, da sie frei von Stahlverunreinigungen sind. Schließlich üben die Gewindebolzen 8 keinen thermischen Einfluß auf die Kokilleninnenplatte 1 auf, da sie nicht mit dieser, sondern mit den Füllstücken 7 verschweißt sind.With the mold wall according to the invention, a variety of Benefits attainable. For example, there are no holes the back of the mold inner plate 1 required. Further no threaded inserts have to be inserted into the inner mold plate 1 be used. The grooves 6, which serve as cooling channels, can be evenly spaced from each other. For used mold inner plates 1 can a higher scrap proceeds can be achieved as they are free of steel impurities are. Finally, the threaded bolts 8 do not practice thermal Influence on the inner mold plate 1, since it is not with this, but are welded to the filler pieces 7.

Darüber hinaus ist noch zu erwähnen, daß bei der erfindungsgemäßen Kokillenwand keine vertikalen Tieflochbohrungen im Bereich der Stege 5 für die Gewindestücke erforderlich sind. Auch eine Paßnut in den Füllstücken 7 und der Kokilleninnenplatte 1 ist nicht erforderlich. In addition, it should also be mentioned that in the invention Mold wall no vertical deep holes in the Area of the webs 5 are required for the threaded pieces. Also a fitting groove in the filler pieces 7 and the inner mold plate 1 is not required.
