Description

Stranggießkokille mit den Gießquerschnitt umschließenden KupferplattenContinuous casting mold with copper plates enclosing the casting cross section
Die Erfindung betrifft eine Stranggießkokille mit den Gießquerschnitt umschließenden Kupferplatten, in denen Kühlkanäle verlaufen, und die Kupferplatten mittels Schraubelementen mit einem Wasserkasten aus Stahl verbunden sind, wobei die Schraubelemente aus Befestigungsbolzen mit einem Gewindeschaft bestehen, der in die Kupferplatte einschraubbar ist.The invention relates to a continuous casting mold with copper plates enclosing the casting cross section, in which cooling channels run, and the copper plates are connected by means of screw elements to a steel water tank, the screw elements consisting of fastening bolts with a threaded shaft that can be screwed into the copper plate.
Es sind verschiedene Arten der Befestigung von geschlitzten oder gebohrten Kokillenplatten bekannt:Various types of attachment of slotted or drilled mold plates are known:
- mit Gewindebohrungen zwischen Kühlschlitzen, mit Gewindebohrungen zwischen oder hinter Kühlkanälen an der Rückseite der Kupferplatte sind Befestigungsvorrichtungen angeschweißt oder angelötet.- With threaded holes between cooling slots, with threaded holes between or behind cooling channels on the back of the copper plate, fastening devices are welded or soldered on.
Eine bekannte Bauweise folgt aus der DE 198 42 674 A1 , wobei die Kokillenin- nenplatte auf ihrer dem Wasserkasten zugewandten Seite Stege mit dazwischen verlaufenden Nuten mit einer Nutbreite aufweist, in denen Füllstücke angeordnet sind. Um die Kokilleninnenplatte am Wasserkasten zu befestigen, wird dort vorgeschlagen, dass die Nuten Hinterschneidungen mit einer Hinterschnei- dungsdicke aufweisen, ferner, dass die Füllstücke Verbindungselemente mit einer Verbindungselementdicke aufweisen und dass die Füllstücke lösbar in den Hinterschneidungen eingreifen und die Schraubverbindungen zwischen den Füllstücken und dem Wasserkasten angeordnet sind. Diese Ausbildung löst zwar einige Probleme, erfordert jedoch nicht unbeachtliche Montage- und Her- stellkosten. Die vorstehend aufgeführten Befestigungsausbildungen sind mit verschiedenen Nachteilen verbunden. Gewindebohrungen erfordern zwischen den Kühlschlitzen größere Abstände und behindern bzw. verändern die Wärmeabfuhr aus der Kupferplatte an das Kühlwasser. Dadurch entstehen Temperaturunterschiede auf der der Gießschmelze zugewandten Kupferplattenseite. Im anderen Fall, dass sich die Befestigungsbolzen hinter den Kühlschlitzen befinden, muss die Kupferplatte dicker gewählt werden und wird dadurch teurer. Die angeschweißten oder angelöteten Befestigungsbolzen können nicht so stark belastet werden wie geschraubte Befestigungsbolzen, weil die Bruchlast in Abhängigkeit von der Güte der Verbindung stärker schwankt und der Bruch fast verfor- mungslos spröde erfolgt.A known construction follows from DE 198 42 674 A1, the inner mold plate on its side facing the water tank having webs with grooves running therebetween with a groove width in which filler pieces are arranged. In order to attach the inner mold plate to the water tank, it is proposed there that the grooves have undercuts with an undercut thickness, furthermore that the filler pieces have connecting elements with a connecting element thickness and that the filler pieces releasably engage in the undercuts and the screw connections between the filler pieces and the Water box are arranged. While this training solves some problems, it does not require insignificant assembly and manufacturing costs. The attachment designs listed above are associated with various disadvantages. Tapped holes require larger distances between the cooling slots and hinder or change the heat dissipation from the copper plate to the cooling water. This creates temperature differences on the copper plate side facing the casting melt. In the other case, that the fastening bolts are located behind the cooling slots, the copper plate must be made thicker and therefore more expensive. The welded or soldered-on fastening bolts cannot be subjected to as much stress as screwed fastening bolts because the breaking load fluctuates more depending on the quality of the connection and the fracture is almost brittle without deformation.
Der Erfindung liegt die Aufgabe zugrunde, eine Befestigung von Kupferplatten für Stranggießkokillen zu schaffen, bei der alle Befestigungsbolzen zuverlässig mit der gleichen Kraft belastet werden, der Bruch nicht verformungslos erfolgt, die Wärmeabfuhr aus der Kokille weitgehend gleichmäßig erfolgt und die Befestigung keine zusätzliche Vergrößerung der Kupferplattendicke erfordert.The invention has for its object to provide a fastening of copper plates for continuous casting molds, in which all fastening bolts are reliably loaded with the same force, the break is not deformation-free, the heat dissipation from the mold is largely uniform and the attachment no additional increase in the copper plate thickness requires.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Befestigungsbolzen mit ihren Mittellängsachsen jeweils mittig zwischen zwei benach- harten, in der Kupferplatte parallel untereinander und quer zur Mittellängsachse angeordneten Kühlmittelbohrungen verlaufend angeordnet sind. Dadurch können alle Befestigungselemente zuverlässig mit der gleichen Kraft belastet werden und der Bruch erfolgt nicht verformungslos, wobei auch die Wärmeabfuhr aus der Kokille weitgehend gleichmäßig erfolgt und genug Plattendicke für das Innengewinde vorhanden ist.The object is achieved according to the invention in that the fastening bolts with their central longitudinal axes are each arranged centrally between two adjacent coolant bores arranged in the copper plate parallel to one another and transversely to the central longitudinal axis. As a result, all fastening elements can be reliably loaded with the same force and the fracture does not take place without deformation, the heat dissipation from the mold also taking place largely uniformly and there being enough plate thickness for the internal thread.
Eine Vergrößerung der Kupferplattendicke ist ebenfalls nicht notwendig. Die Voraussetzung dieser Ergebnisse sind Kühlmittelbohrungen, die einen kreiszylindrischen Querschnitt aufweisen. Die Verwendung von Kühlmittelbohrungen anstelle der nach hinten offenen Kühlschiitze belastet die Befestigungsbolzen nicht durch den Wasserdruck. Somit können weniger Befestigungsbolzen oder Befestigungsbolzen mit einem geringeren Durchmesser eingesetzt werden.It is also not necessary to increase the copper plate thickness. The prerequisite for these results are coolant holes that have a circular cylindrical cross section. The use of coolant holes instead of the cooling slots open to the rear puts a strain on the fastening bolts not by water pressure. This means that fewer fastening bolts or fastening bolts with a smaller diameter can be used.
Der Abstand zwischen den Kühlmittelbohrungen kann über die gesamte Kokillenfläche gleich groß bzw. annähernd gleich groß sein und muss auch im Be- reich der Befestigungsbohrungen nicht größer gewählt werden, wodurch die Wärmeabfuhr gleichmäßiger ist und nur geringe Temperaturunterschiede auf der Kokillenvorderseite auftreten.The distance between the coolant holes can be of the same size or approximately the same size over the entire mold area and also does not have to be selected larger in the area of the mounting holes, as a result of which the heat dissipation is more uniform and only slight temperature differences occur on the front side of the mold.
Ein weiterer Vorteil ist, dass die Befestigungsbolzen nicht mehr in Gießrichtung untereinander angeordnet sein müssen, sondern versetzt sein können. Somit kann die Anzahl und die Verteilung der Befestigungsbolzen den örtlich wirkenden Belastungen angepasst werden.Another advantage is that the fastening bolts no longer have to be arranged one below the other in the casting direction, but can instead be offset. The number and distribution of the fastening bolts can thus be adapted to the local loads.
Für die vorgeschlagene Art der Befestigung der Kupferplatten an dem Wasser- kästen ist es weiterhin nicht notwendig, die Dicke der Kupferplatte so weit zu vergrößern, dass sich die Befestigungsgewinde vollständig hinter den Kühlmittelbohrungen befinden. Weiterhin streut die Bruchlast von formschlüssigen Verbindungen, wie z.B. Gewinden, nicht so stark wie von stoffschlüssigen Verbindungen. Ein Bruch erfolgt nicht verformungslos spröde.For the proposed way of fastening the copper plates to the water tanks, it is furthermore not necessary to increase the thickness of the copper plate to such an extent that the fastening threads are located completely behind the coolant holes. Furthermore, the breaking load of positive connections, e.g. Thread, not as strong as that of cohesive connections. A break is not brittle without deformation.
Eine Ausgestaltung sieht vor, dass die Befestigungsbolzen die zwei benachbarten, quer verlaufenden Kühlmittelbohrungen an deren Umfang anschneiden. Trotzdem wird die Kühlwirkung nicht wesentlich beeinträchtigt und es können die bisherigen Abstände der Kühlbohrungen bei zylindrischem Querschnitt bei- behalten werden.One embodiment provides that the fastening bolts cut the two adjacent, transverse coolant bores on their circumference. Nevertheless, the cooling effect is not significantly impaired and the previous spacing of the cooling holes with a cylindrical cross section can be retained.
Eine Weiterentwicklung sieht vor, dass der Befestigungsbolzen jeweils in einem Adapter eingeschraubt ist, wobei der Adapter mit seiner Mittellängsachse mittig zwischen den in der Kupferplatte quer verlaufenden Kühlmittelbohrungen ver- läuft. Der Abstand zwischen den Kühlmittelbohrungen braucht nicht sehr groß gewählt zu werden und kann über die gesamte Kühlfläche gleich groß sein und muss auch im Bereich der Befestigungsbohrungen nicht größer sein. Die Befestigungsbolzen werden an dem Adapter befestigt und gewährleisten somit die Verbindung der Kupferplatte mit dem Stahlrahmen des Wasserkastens. Die Verwendung von Adaptern verringert zusätzlich die Biegebelastung der Befestigungsbolzen, die mittels des Gewindes mit den Adaptern verbunden sind. Das Gewinde wirkt hier so ähnlich wie ein Gelenk.A further development provides that the fastening bolt is screwed into an adapter, the adapter having its central longitudinal axis running centrally between the coolant holes running transversely in the copper plate. The distance between the coolant holes need not be chosen to be very large and can be the same size over the entire cooling surface and does not have to be larger in the area of the mounting holes. The fastening bolts are attached to the adapter and thus ensure the connection of the copper plate to the steel frame of the water tank. The use of adapters additionally reduces the bending load on the fastening bolts, which are connected to the adapters by means of the thread. The thread acts like a joint here.
Nach einer Abwandlung ist vorgesehen, dass der Adapter die zwei benachbarten, quer verlaufenden Kühlmittelbohrungen an deren Umfang mit seinem Gewindeschaft anschneidet. Dadurch ragen die Verschraubungen zwar an einigen Stellen in die Kühlmittelbohrung. Aufgrund ihres günstigen Profils ist in Strömungsrichtung des Kühlmittels nur mit einer geringen Beeinflussung der Kühlwasserströmung zu rechnen.According to a modification, it is provided that the adapter cuts the two adjacent, transverse coolant bores on their circumference with its threaded shaft. As a result, the screw connections protrude into the coolant bore at some points. Due to their favorable profile, only a slight influence on the cooling water flow is to be expected in the flow direction of the coolant.
Eine weitere Ausgestaltung sieht vor, dass der Adapter in einer Ausnehmung des Wasserkastens eingelassen ist. Dadurch wird ein vorteilhafter Raum im Wasserkasten geschaffen, so dass der Adapter nur in geringem Abstand zur Kupferplatte steht.Another embodiment provides that the adapter is embedded in a recess in the water tank. This creates an advantageous space in the water tank so that the adapter is only a short distance from the copper plate.
Das Austreten von Wasser aus angeschnittenen Kühlmittelbohrungen kann da- hingehend verhindert werden, dass der Adapter mittels einer Dichtung gegen die Kupferplatte abgedichtet ist.The escape of water from cut coolant bores can be prevented by sealing the adapter against the copper plate by means of a seal.
Die vorgeschlagene Erfindung ist besonders für die Befestigung von dünnwandigen Trichterkokillen geeignet. Derartige Stranggießkokillen werden nach ei- nem besonderen Verfahren dahingehend hergestellt, dass die aus Kühlmittelbohrungen in der Kupferplatte bestehenden Kühlkanäle vor einer weiteren Bearbeitung gerade gebohrt werden, danach die Kupferplatte durch Pressen auf die Kokillenform vorgeformt und bearbeitet wird und dass danach das Befestigungsinnengewinde für den Adapter oder den Befestigungsbolzen einge- schnitten wird. Hier können die Kühlmittelbohrungen also bereits vor der Umformung als gerade, durchgehende Bohrungen in die Kupferplatte eingebracht werden und dann mit umgeformt werde h- Das-Einbringerr von abknickenden Bohrungen von zwei Seiten wie bisher entfällt.The proposed invention is particularly suitable for the attachment of thin-walled funnel molds. Such continuous casting molds are produced according to a special method in such a way that the cooling channels consisting of coolant bores in the copper plate are drilled prior to further processing, then the copper plate is preformed and processed by pressing onto the mold shape and that the fastening internal thread for the adapter or the fastening bolt is cut into. Here, the coolant holes can be drilled into the copper plate as straight, continuous holes before the forming and then be reshaped with h- Das-Bringer of kinking holes from two sides as before.
In der Zeichnung ist ein Ausführungsbeispief der Erfindung dargestellt und wird im folgenden näher erläutert.An exemplary embodiment of the invention is shown in the drawing and is explained in more detail below.
Es zeigen:Show it:
Fig. 1 einen senkrechten Schnitt durch die Kupferplatte mit Wasserkasten einer Stranggießkokille und Fig. 2 einen waagerechten Schnitt A-B gemäß Fig. 1.1 shows a vertical section through the copper plate with the water tank of a continuous casting mold, and FIG. 2 shows a horizontal section A-B according to FIG. 1.
Mehrere der Kupferplatten 1 umschließen einen nicht näher dargestellten Gießquerschnitt, der z.B. rechteckig oder quadratisch sein kann. In der Kupferplatte 1 verlaufen eingebrachte Kühlmittelbohrungen 2 mit einem zylindrischen Kreisquerschnitt. Die Kupferplatte 1 ist mittels Schraubelementen mit einem Wasserkasten 5 verbunden, von dem das Kühlwasser in die Kühlmittelbohrungen 2 gepumpt und nach Wärmeaufnahme zur Rückkühlung wieder abgeführt wird. Die Schraubelemente bestehen hier aus Befestigungsbolzen 3 mit einem Gewindeschaft 3b, der in die Kupferplatte 1 eingeschraubt ist. Im allgemeinen sind die Befestigungsbolzen 3 mit ihren Mittellängsachsen 3a jeweils mittig zwischen zwei benachbarten, in der Kupferplatte 1 parallel untereinander und quer zur Mittellängsachse 3a angeordneten Kühlmittelbohrungen 2 verlaufend angeordnet. Je nach den gewählten Abmessungen kann der Befestigungsbolzen 3 die zwei benachbarten, quer verlaufenden Kühlmittelbohrungen 2 an deren Umfang schneiden, wie sich aus den Fig. 1 und 2 ergibt. Um eine Gelenkwirkung zu erzielen, ist der Befestigungsbolzen 3 alternativ jeweils noch in einem Adapter 4 eingeschraubt, wobei der Adapter 4 mit seiner Mittellängsachse 4a mittig zwischen den in der Kupferplatte 1 quer verlaufenden Kühlmittelbohrungen 2 verlaufend eingeschraubt ist. Zu diesem Zweck weist der Adapter Au- ßengewinde 6 auf, das in die Kupferplatte 1 eingeschraubt ist und Innengewinde 7, in das der Befestigungsbolzen 3 eingeschraubt ist. Analog dazu besitzt die Kupferplatte 1 Befestigungsinnengewinde 1a. Es kann gewollt sein, dass der Adapter 4 die zwei benachbarten, quer verlaufenden Kühlmittelbohrungen 2 an deren Umfang mit seinem Gewindeschaft 4b anschneidet.Several of the copper plates 1 enclose a casting cross section, not shown, which can be rectangular or square, for example. Coolant bores 2 with a cylindrical circular cross section run in the copper plate 1. The copper plate 1 is connected by means of screw elements to a water tank 5, from which the cooling water is pumped into the coolant bores 2 and, after absorbing heat, is discharged again for re-cooling. The screw elements here consist of fastening bolts 3 with a threaded shaft 3b which is screwed into the copper plate 1. In general, the fastening bolts 3 with their central longitudinal axes 3a are each arranged centrally between two adjacent coolant bores 2 arranged in the copper plate 1 parallel to one another and transversely to the central longitudinal axis 3a. Depending on the dimensions selected, the fastening bolt 3 can cut the two adjacent, transverse coolant bores 2 on their circumference, as can be seen from FIGS. 1 and 2. In order to achieve a joint effect, the fastening bolt 3 is alternatively screwed into an adapter 4, the adapter 4 being screwed with its central longitudinal axis 4a centrally between the coolant bores 2 running transversely in the copper plate 1. For this purpose, the adapter has external thread 6, which is screwed into the copper plate 1, and internal thread 7, into which the fastening bolt 3 is screwed. Analogous to that the copper plate 1 fastening internal thread 1a. It may be desired that the adapter 4 cuts the two adjacent, transverse coolant bores 2 on their circumference with its threaded shaft 4b.
Der Adapter 4 ist in einer Ausnehmung 9 des Wasserkastens 5 eingelassen, wodurch das "Gelenk" näher an die Kupferplatte 1 heranrückt. Um ein Abfließen von Kühlwasser durch das Befestigungsinnengewinde 1a mit dem Außengewinde 6 zu verhindern, ist der Adapter 4 mittels einer Dichtung 8 gegen die Kupferplatte 1 abgedichtet.The adapter 4 is embedded in a recess 9 in the water tank 5, as a result of which the "joint" moves closer to the copper plate 1. In order to prevent cooling water from flowing out through the fastening internal thread 1 a with the external thread 6, the adapter 4 is sealed against the copper plate 1 by means of a seal 8.
Die Herstellung der Kokillenplatte 1 aus Kupfer , insbesondere für eine trichterförmige Stranggießkokille mit konstanter Plattendicke, in die Kühlkanäle eingebracht werden, erfolgt in der Art, dass die aus kreiszylindrischen Kühlmittelbohrungen 2 in der Kupferplatte 1 bestehenden Kuhlkanale vor einer weiteren Bearbeitung gerade durchgebohrt werden, danach die Kupferplatte 1 durch Pres- sen auf die Kokillenform vorgeformt und bearbeitet wird und dass danach das Befestigungsinnengewinde 1a für den Adapter 4 oder den Befestigungsbolzen 3 eingeschnitten wird. The production of the mold plate 1 from copper, in particular for a funnel-shaped continuous casting mold with a constant plate thickness, into which the cooling channels are introduced, takes place in such a way that the cooling channels consisting of circular-cylindrical coolant bores 2 in the copper plate 1 are just drilled before further processing, after which the Copper plate 1 is preformed and pressed onto the mold and then the internal thread 1a for the adapter 4 or the fastening bolt 3 is cut.
