Description

Die Erfindung betrifft einerseits ein Kokillenrohr gemäß den Merkmalen im Oberbegriff des Anspruchs 1.On the one hand, the invention relates to a mold tube according to the features in the preamble of claim 1.

Andererseits richtet sich die Erfindung auf ein Verfahren zum Rekalibrieren eines im Einsatz gewesenen Kokillenrohrs.On the other hand, the invention is directed to a method for recalibrating an im Use of the mold tube.

Kokillenrohre zum Stranggießen werden bekanntlich in der Kühlung dienenden Wasserkästen dicht lagefixiert. Um den hohen Kühlwasserdrücken standzuhalten, werden die Kokillenrohre an ihren oberen Enden versteift, so daß sie ihre Formstabilität beibehalten. In diesem Zusammenhang ist es insbesondere bei den einen Doppel-T-förmigen Querschnitt aufweisenden "beam-blank"- oder "dogbone"-Kokillen bekannt, in die einander gegenüberliegenden Außenkanäle an den oberen Enden Keile einzuschweißen, so daß solche Kokillenrohre in der Stirnansicht dann einen weitgehend rechteckigen Querschnitt besitzen.Mold tubes for continuous casting are known to be used in cooling Water boxes tightly fixed. To withstand the high cooling water pressures, the mold tubes are stiffened at their upper ends so that they retain their shape maintained. In this context, it is particularly with some Double-T-shaped cross-section with "beam-blank" or "dogbone" molds known, in the opposite outer channels at the upper ends Weld wedges so that such mold tubes in the front view then one have largely rectangular cross-section.

Beim Rekalibrieren derartiger Kokillenrohre unter Anwendung der Sprengumformung (Accumold-Verfahren) erwiesen sich indessen die eingeschweißten Keile als hinderlich im Zuge der Umformung. Auch rissen die Schweißnähte zum Teil. Dies war dann mit einer nicht mehr einwandfreien Abdichtung verbunden. Des weiteren zeigte sich, daß die ursprüngliche Form am oberen Ende der Kokillenrohre nicht oder nur schwer zu rekalibrieren war. When recalibrating mold tubes of this type using blasting (Accumold process), however, the welded-in wedges proved to be a hindrance in the course of the reshaping. The weld seams also tore in part. Then that was associated with a no longer perfect seal. It also showed that the original shape at the top of the mold tubes is not or only was difficult to recalibrate.

Der Erfindung liegt ausgehend vom Stand der Technik die Aufgabe zugrunde, einerseits ein Kokillenrohr zu schaffen, das einwandfrei dicht und formstabilisiert in einem Wasserkasten lagefixiert werden kann, und andererseits ein Verfahren zum Rekalibrieren eines im Einsatz gewesenenen Kokillenrohrs vorzustellen, bei welchem das Kokillenrohr mehrfach nachgearbeitet werden kann, ohne daß die Nachbearbeitungen zu Abdichtungsproblemen oder Schädigungen des Kokillenwerkstoffs führen.Starting from the prior art, the invention is based on the object, on the one hand to create a mold tube that is perfectly sealed and dimensionally stable in one Water box can be fixed in position, and on the other hand a method for recalibration to introduce a mold tube that was in use, in which the The mold tube can be reworked several times without the reworking lead to sealing problems or damage to the mold material.

Hinsichtlich des das Kokillenrohr betreffenden Teils dieser Aufgabe wird die Lösung in den im Kennzeichen des Anspruchs 1 aufgeführten Merkmalen gesehen.With regard to the part of this task relating to the mold tube, the solution becomes seen in the features listed in the characterizing part of claim 1.

Die Lösung des das Verfahren betreffenden Teils der Aufgabe besteht in den Merkmalen des Anspruchs 4.The solution to the part of the task relating to the method consists in the features of claim 4.

Danach wird jetzt im Abstand zur oberen Stirnseite der Rohrwand eines Kokillenrohrs eine äußere im Querschnitt insbesondere rechteckige Umfangsnut vorgesehen. Ferner wird benachbart zur oberen Stirnseite ein umlaufender Absatz am Kokillenrohr erzeugt. Dieser Absatz dient der paßgenauen und dichtenden Festlegung eines Versteifungsrahmens, der sich außerdem am Flansch des Wasserkastens abstützt. Auch gegenüber dem Wasserkasten ist der Versteifungsrahmen abgedichtet. Unterhalb des Versteifungsrahmens liegen zwei U-förmige Flansche mit inneren Raststegen, die von gegenüberliegenden Seiten her in die Umfangsnut an der Rohrwand fassen. Die radiale Erstreckung der Raststege ist kleiner als die Tiefe der Umfangsnut bemessen. Nachdem die U-förmigen Flansche über die Raststege in der Umfangsnut lageorientiert sind, wird der Versteifungsrahmen auf den Absatz geschoben und anschließend mit den beiden U-förmigen Flanschen durch Schrauben fest verbunden. Auf diese Art und Weise ist das obere Ende des Kokillenrohrs gegenüber Kühlwasserdrücken ausreichend formstabilisiert. Schweißarbeiten sind nicht mehr notwendig, so daß auch nicht mehr die Gefahr besteht, daß der Kokillenwerkstoff beschädigt wird. Then, at a distance from the upper end face of the tube wall, a mold tube an outer circumferential groove, in particular rectangular in cross section, is provided. Furthermore, a circumferential shoulder on the mold tube is adjacent to the upper end face generated. This paragraph is used for the precise and sealing definition a stiffening frame, which is also on the flange of the water tank supports. The stiffening frame is also sealed against the water tank. Below the stiffening frame are two U-shaped flanges with inner ones Locking webs, which from opposite sides in the circumferential groove on the Grasp the pipe wall. The radial extension of the locking bars is smaller than the depth of the Dimensioned circumferential groove. After the U-shaped flanges over the locking bars in the circumferential groove are oriented, the stiffening frame is on the heel pushed and then with the two U-shaped flanges by screws firmly connected. In this way, the upper end of the mold tube Sufficiently stabilized against cooling water pressures. Are welding work no longer necessary, so that there is no longer any risk that the mold material is damaged.

Soll nun ein im Einsatz gewesenes Kokillenrohr rekalibriert werden, brauchen lediglich der Versteifungsrahmen und die U-förmigen Flansche entfernt zu werden, um anschließend den inneren Formhohlraum wieder herzustellen, damit er den Erfordernissen beim Stranggießen genügt. Ist der Formhohlraum wieder hergestellt, was in der Regel mit einer Abnahme der Wanddicke am oberen Ende des Kokillenrohrs verbunden ist, wird lediglich der Absatz entsprechend der Abnahme der Wanddicke nachgearbeitet und ein daran angepaßter neuer Versteifungsrahmen aufgesetzt, der dann mit den verbleibenden U-förmigen Flanschen verschraubt wird. Diese können deshalb verbleiben, weil die radiale Erstreckung der Raststege kleiner als die Tiefe der Umfangsnut bemessen ist.If a mold tube that has been in use is now to be recalibrated, all you need is the stiffening frame and the U-shaped flanges to be removed then restore the inner mold cavity to meet the requirements with continuous casting is sufficient. Is the mold cavity restored what? usually with a decrease in wall thickness at the top of the mold tube is connected, only the paragraph corresponding to the decrease in wall thickness reworked and put on a new stiffening frame adapted to it then bolted to the remaining U-shaped flanges. these can therefore remain because the radial extension of the locking webs is smaller than the depth the circumferential groove is dimensioned.

Vorteilhaft ist es, daß dieses Kalibrieren mehrfach wiederholbar ist und lediglich entsprechende Versteifungsrahmen bereitgestellt werden müssen.It is advantageous that this calibration can be repeated several times and only corresponding ones Stiffening frame must be provided.

Gemäß einer vorteilhaften Ausführungsform ist nach Anspruch 2 die dem Tiefsten des Absatzes zugewandte Innenkante des Versteifungsrahmens mit einer Ausnehmung zur Aufnahme des Dichtrings versehen. Dieser Dichtring wird beim Verschrauben des Versteifungsrahmens mit den U-förmigen Flanschen in den Eckbereich des Absatzes gedrückt und auf diese Weise die Abdichtung sichergestellt.According to an advantageous embodiment, the lowest is according to claim 2 of the paragraph facing inner edge of the stiffening frame with a recess to accommodate the sealing ring. This sealing ring is used when screwing of the stiffening frame with the U-shaped flanges in the corner area of the paragraph pressed and in this way ensures the seal.

Besonders vorteilhaft sind die Merkmale der Ansprüche 1 und 2 bei einem Doppel-T-förmig konfigurierten Kokillenrohr gemäß Anspruch 3 anwendbar, wie es beispielsweise in Form einer "beam-blank"- oder einer "dogbone"-Kokille bekannt ist. Denkbar ist die Anwendung aber auch bei Knüppel- und Bloomformaten.The features of claims 1 and 2 are particularly advantageous in the case of a double T-shaped configured mold tube according to claim 3 applicable, for example in the form of a "beam-blank" - or a "dogbone" mold. Conceivable is also used for billet and bloom formats.

Das Wiederherstellen des inneren Formhohlraums eines Kokillenrohrs kann mit allen bekannten Verfahren durchgeführt werden. Besonders vorteilhaft ist jedoch die Wiederherstellung des Formhohlraums durch Sprengumformung bei einem in das Kokillenrohr eingeführten Formdorn entsprechend den Merkmalen des Anspruchs 5. Restoring the inner mold cavity of a mold tube can be done with all known methods are carried out. However, the is particularly advantageous Restoration of the mold cavity by explosive molding at one in the Mold tube inserted mandrel according to the features of claim 5.

Das nach der Wiederherstellung des inneren Formhohlraums erfolgende Nacharbeiten des Absatzes am oberen Ende des Kokillenrohrs wird nach Anspruch 6 vorteilhafterweise durch eine Fräsoperation durchgeführt.Reworking after restoration of the inner mold cavity the paragraph at the upper end of the mold tube is advantageously according to claim 6 performed by a milling operation.

Mit 1 ist ist in den Figuren 1 bis 3 ein aus Kupfer bestehendes Kokillenrohr mit einem Doppel-T-förmigen Querschnitt bezeichnet. Ein derartiges Kokillenrohr 1 wird auch "beam-blank"-Kokille genannt.1 to 3 is a mold tube made of copper with one in FIGS Designated double T-shaped cross section. Such a mold tube 1 is also called "beam-blank" mold.

Um ein solches Kokillenrohr 1 dicht und formstabil in einem nicht näher dargestellten Wasserkasten 2 lagezufixieren (Figur 3), ist benachbart zur oberen Stirnseite 3 der Rohrwand 4 ein im Querschnitt rechteckiger umfangsseitiger Absatz 5 vorgesehen. Dieser Absatz 5 dient der Aufnahme eines Versteifungsrahmens 6, dessen Oberseite 7 in einer Ebene mit der Stirnseite 3 der Rohrwand 4 verläuft. Der Versteifungsrahmen 6 hat eine im wesentlichen rechteckige Außenkontur mit gerundeten Eckbereichen 8. In der Figur 2 ist der Versteifungsrahmen 6 um 180° geklappt dargestellt.Around such a mold tube 1 tightly and dimensionally stable in a not shown Fixing the water tank 2 in position (FIG. 3) is adjacent to the upper end face 3 of the Pipe wall 4 a circumferential shoulder 5 with a rectangular cross section is provided. This paragraph 5 is used to accommodate a stiffening frame 6, the top 7 runs in one plane with the end face 3 of the tube wall 4. The stiffening frame 6 has a substantially rectangular outer contour with rounded Corner regions 8. In FIG. 2, the stiffening frame 6 is shown folded through 180 °.

In einem Abstand unterhalb des Absatzes 5, der etwa der vertikalen Erstreckung des Absatzes 5 entspricht, ist in der Rohrwand 4 eine äußere Umfangsnut 9 rechteckigen Querschnitts vorgesehen. Die Umfangsnut 9 dient der Aufnahme von an zwei U-förmigen Flanschen 10 ausgebildeten inneren Raststegen 11. Die radiale Erstreckung der Raststege 11 ist kleiner als die Tiefe der Umfangsnut 9 bemessen. Auch die Eckbereiche 12 der Flansche 10 sind gerundet.At a distance below paragraph 5, which is approximately the vertical extension of the Paragraph 5 corresponds, an outer circumferential groove 9 is rectangular in the tube wall 4 Cross section provided. The circumferential groove 9 serves to accommodate two U-shaped ones Flanges 10 trained inner locking ridges 11. The radial extension the locking webs 11 is smaller than the depth of the circumferential groove 9. The corner regions 12 of the flanges 10 are also rounded.

Nach dem Einschieben der Raststege 11 in die Umfangsnut 9 wird der Versteifungsrahmen 6 mit einem in eine Ausnehmung 13 im Bereich der Innenkante 14 eingebetteten Dichtring 15 auf den Absatz 5 gesetzt und anschließend über mehrere sich entlang der Kontur des Kokillenrohrs 1 erstreckende Schraubbolzen 16 mit den Flanschen 10 verspannt.After inserting the locking webs 11 into the circumferential groove 9, the stiffening frame 6 with one embedded in a recess 13 in the area of the inner edge 14 Sealing ring 15 placed on paragraph 5 and then over several extending along the contour of the mold tube 1 bolts 16 with the Flanges 10 braced.

Der Versteifungsrahmen 6 wird von Halteblechen 17 unterfangen, die mit dem Wasserkasten 2 verschraubt sind. Eine Dichtung 21 zwischen dem Versteifungsrahmen 6 und dem Wasserkasten 2 dient der Abdichtung gegenüber dem darüber liegenden Flansch 18 des Wasserkastens 2. Mit 19 ist in der Figur 3 der Wasserleitmantel bezeichnet.The stiffening frame 6 is underpinned by holding plates 17 which are connected to the water tank 2 are screwed. A seal 21 between the stiffening frame 6 and the water box 2 serves to seal against the overlying Flange 18 of the water box 2. With 19 in Figure 3, the water jacket is designated.

Zur Rekalibrierung eines Kokillenrohrs 1 wird dieses ausgebaut und es werden anschließend der Versteifungsrahmen 6 sowie die Flansche 10 entfernt. Danach wird das Kokillenrohr 1 unter Einführung eines nicht näher dargestellten Formdorns in den Formhohlraum 20 durch Sprengumformen kalibriert. Bei diesem Sprengumformen reduziert sich die Dicke der Rohrwand 4 im oberen Bereich. Aufgrund dieser Reduzierung wird anschließend der Absatz 5 entsprechend nachbearbeitet, insbesondere nachgefräst. Die Umfangsnut 9 braucht nicht nachgearbeitet zu werden, da ihre Tiefe größer ist als die Radialerstreckung der Raststege 11. Nach der Bearbeitung des Absatzes 5 wird ein daran angepaßter neuer Versteifungsrahmen 6 aufgesetzt und mit den Flanschen 10 verspannt.To recalibrate a mold tube 1, it is removed and it is then the stiffening frame 6 and the flanges 10 removed. After that the mold tube 1 with the introduction of a mandrel, not shown in the mold cavity 20 is calibrated by explosive molding. With this explosive forming the thickness of the tube wall 4 is reduced in the upper region. Based on these Subsequently, paragraph 5 is reworked accordingly, in particular milled. The circumferential groove 9 does not need to be reworked since their depth is greater than the radial extent of the locking webs 11. After processing of paragraph 5, a new stiffening frame 6 is fitted and braced with the flanges 10.

Bei einer Wanddickenabnahme von etwa 0,7 mm je Kalibrierung kann ein Kokillenrohr 1 etwa dreimal nachkalibriert werden. With a decrease in wall thickness of approximately 0.7 mm per calibration, a Mold tube 1 can be recalibrated about three times.
