Aus DE-OS 24 15 224 ist ein Verfahren zum Steuern der Kühlleistung von Schmalseitenwänden bei Plattenkokillen beim Stranggießen bekannt, wobei die Schmalseitenwände zwischen Breitseitenwänden festgeklemmt werden, und vor Gießbeginn der Formhohlraum zwischen den Schmalseitenwänden mit einem in Stranglaufrichtung konvergierenden und der Stahlqualität und der Strangbreite angepaßten Gießkonus versehen wird, welcher während des Gießbetriebes vorgebbar einstellbar ist.From DE-OS 24 15 224 is a method for controlling the cooling capacity of Narrow side walls in plate molds in continuous casting are known, the Narrow side walls are clamped between broad side walls, and in front The mold cavity begins to pour between the narrow side walls with an in Strand direction converging and the steel quality and strand width adapted casting cone is provided, which can be specified during the casting operation is adjustable.
Hierbei besteht eine Schmalseitenwand aus einer dem Formhohlraum zugewandten
Kupferplatte, die fest mit einer Stützplatte verbunden ist.
Weiterhin ist aus EP 0 086 405 eine Kokillenwand bekannt, die aus einer Kupferplatte
und einer biegsamen mit Kühlkanälen versehenen Verbundplatte besteht. Here, a narrow side wall consists of a copper plate facing the mold cavity, which is firmly connected to a support plate.
Furthermore, a mold wall is known from EP 0 086 405, which consists of a copper plate and a flexible composite plate provided with cooling channels.
Auch bei dieser biegsamen Kokillenwand ist die aus Kupfer aufgebaute zum Formhohlraum hinweisende Platte innig mit einer Trägerwand verbunden.With this flexible mold wall, too, the copper one is used for Form cavity indicating plate intimately connected to a support wall.
Bei einem Formatwechsel der oben genannten Plattenkokillen sind jeweils die kompletten Seitenleisten zu wechseln.When changing the format of the above-mentioned plate molds are the to change complete sidebars.
In Kenntnis der o.g. Nachteile hat sich die Erfindung das Ziel gesetzt, eine Vorrichtung
zu schaffen und ein entsprechendes Verfahren vorzugeben, bei dem sich mit
einfachen konstruktiven Mitteln ein schnelles und dabei sicheres Wechseln des
Brammenformates einer in einer Plattenkokille erzeugten Bramme bezüglich seiner
Dicke durchführen läßt. Die Erfindung erreicht dieses Ziel durch die kennzeichnenden
Merkmale des Vorrichtungsanspruchs 1 und des Verfahrensanspruchs 11.Knowing the above Disadvantages, the invention has set itself the goal of a device
to create and to provide a corresponding procedure, in which with
simple constructive means a quick and safe change of the
Slab format of a slab produced in a plate mold with regard to its
Thickness can be carried out. The invention achieves this goal by the characterizing
Features of device claim 1 and
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen 2 bis 10 definiert.Advantageous developments of the invention are in the subclaims Defined 2 to 10.
Erfindungsgemäß sind die Seitenleisten aus einem Wechselteil und einem Halteteil aufgebaut. Das Wechselteil besteht dabei aus Kupfer und besitzt eine U-förmige Gestalt, wobei die beiden Schenkel auf der dem Formhohlraum abgekehrten Seite angeordnet sind.According to the side strips are made of an interchangeable part and a holding part built up. The interchangeable part consists of copper and has a U-shaped Shape, with the two legs on the side facing away from the mold cavity are arranged.
In den Freiraum des U-förmigen Wechselteils ragt ein Halteteil, welches über Preßelemente mit den Schenkeln des Wechselteils lösbar verbindbar sind.A holding part protrudes into the free space of the U-shaped interchangeable part Press elements are releasably connectable to the legs of the interchangeable part.
Zur kraftschlüssigen Verbindung kommen als Preßelemente Membranen oder auch Federn zum Einsatz, wobei die letzteren durch hydraulische Elemente beim Wechseln der Wechselteile zusammengedrückt werden und während des Betriebes sich an der Innenseite der Schenkel abstützen.For the non-positive connection, membranes or also come as pressing elements Springs are used, the latter by hydraulic elements when changing of the interchangeable parts are compressed and during operation on the Support the inside of the thighs.
In einer vorteilhaften Ausgestaltung sind die Schenkel mit Nocken versehen, so daß sie eine L-Form aufweisen. Bei dieser Ausgestaltung stützen sich die Preßelemente auf der zum Formhohlraum weisenden Seite der Nocken ab und drücken die Stirnfläche des Halteteils gegen die Innenseite des aus Kupfer aufgebauten Wechselteils.In an advantageous embodiment, the legs are provided with cams, so that they have an L shape. In this embodiment, the pressing elements are supported on the side facing the mold cavity and press the End face of the holding part against the inside of the copper Exchange part.
Die sich berührenden Flächen des Halteteils und des Wechselteils sind als Kühlkanäle ausgestaltet. Ohne Minderung der Kühlleistung kann eine Fläche, vorzugsweise die des Halteteils, ebenflächig ausgebildet sein. The contacting surfaces of the holding part and the interchangeable part are cooling channels designed. Without reducing the cooling capacity, an area, preferably that of the holding part, be flat.
Die Abdichtung zwischen den Kanälen wird durch die Zwischenstege als ausreichend angesehen, da geringe Leckagen die Kühlung der aus Kupfer bestehenden Wechselteile nicht mindern.The sealing between the channels is sufficient by the intermediate webs viewed, since small leakages cooling the copper Do not reduce replacement parts.
Die Schenkel der U-förmigen Wechselteile sind so geformt, daß sie sich exakt der Innenfläche der Breitseiten der Kokille anpassen. Bei gleichem Innenaufbau des Halteteils sind diese mit dem Wechselteil sicher verbindbar, ohne daß ein Formwechsel der Halteteile durchzuführen ist.The legs of the U-shaped interchangeable parts are shaped so that they are exactly the Adjust the inside surface of the broad sides of the mold. With the same internal structure of the Holding part these can be securely connected to the interchangeable part without one The shape of the holding parts must be changed.
Das Wechseln der Wechselteile nach Verschleiß oder bei einem Formatwechsel wird wie folgt durchgeführt:
- Die Klemmung der Seitenleisten durch die Breitseiten wird aufgehoben,
- die Pressung der Presselemente zwischen dem Halteteil und dem Wechselteil wird entspannt,
- bei U-förmigen Wechselteilen mit L-förmigem Schenkel werden die kupferförmigen Profile nach oben bzw. nach unten aus der Kokille herausgezogen und zum Wechseln entsprechend wieder eingeführt,
- bei U-förmigen Wechselteilen mit glatten Schenkeln könnten die U-förmigen Kupferprofile zum Forminnenraum bewegt werden, um dann schnell und ungehindert aus der Kokille herausgezogen zu werden. Der Einbau erfolgt in umkehrter Reihenfolge. Die U-förmigen Wechselteile mit glatten Schenkeln können aber auch in einer Weise gewechselt werden, daß die Klemmung zwischen den Breitseiten der Kokille verbleibt, zuerst also die kraftschlüssige Verbindung zwischen dem Halteteil und dem Wechselteil entspannt wird und das Halteteil über die Verstelleinrichtung aus dem Wechselteil herausgezogen wird. Anschließend kann nach Entspannung durch die Breitseiten das Wechselteil aus der Kokille herausgenommen werden. Beim Zusammenbau kann wiederum zuerst das Wechselteil eingeführt und von den Breitseiten geklemmt werden und das Halteteil über die Verstelleinrichtung in den Freiraum des U-förmigen Wechselteils geführt und dort kraftschlüssig geklemmt werden.
- The sidebars are no longer clamped by the broad sides,
- the pressing of the pressing elements between the holding part and the interchangeable part is relaxed,
- in the case of U-shaped interchangeable parts with an L-shaped leg, the copper-shaped profiles are pulled out of the mold upwards or downwards and reinserted accordingly for changing,
- in the case of U-shaped interchangeable parts with smooth legs, the U-shaped copper profiles could be moved to the mold interior in order to be pulled out of the mold quickly and unhindered. Installation is carried out in the reverse order. The U-shaped interchangeable parts with smooth legs can also be changed in such a way that the clamping remains between the broad sides of the mold, i.e. the non-positive connection between the holding part and the interchangeable part is first relaxed and the holding part is pulled out of the interchangeable part via the adjusting device becomes. Then, after relaxing through the broad sides, the interchangeable part can be removed from the mold. During assembly, the interchangeable part can in turn be inserted and clamped from the broad sides, and the holding part can be guided into the free space of the U-shaped interchangeable part via the adjusting device and clamped there in a force-locking manner.
