Description

Die vorliegende Erfindung betrifft eine Kokille zum Stranggießen von Vorblöcken, Brammen oder Knüppeln, mit einem von einem Stützmantel umgebenen Kokillenrohr, das sich über seine in Längsrichtung verlaufenden und über den Umfang verteilte Stützprofile am Stützmantel abstützt und mit diesem über Verbindungsmittel formschlüssig verbunden ist, wobei zwischen dem Stützmantel und dem Kokillenrohr Kühlkanäle zur Führung von Kühlwasser über den gesamten Umfang verteilt und im wesentlichen über die gesamte Kokillenlänge angeordnet sind.The present invention relates to a mold for the continuous casting of blooms, slabs or billets, with a surrounding of a support jacket mold tube, which is supported on its longitudinally extending and circumferentially distributed support profiles on the support shell and is positively connected thereto via connecting means, wherein between the cooling jacket channels are distributed over the entire circumference of the support shell and the mold tube for the guidance of cooling water and arranged substantially over the entire Kokillenlänge.

Stranggießkokillen sind wiederverwendbare und nach unten hin offene Formen zum Gießen von Metallen oder Legierungen. Hierzu wird das flüssige Metall oder die flüssige Legierung durch die aus gekühlten Kupferplatten bestehende Kokille geleitet, wo das Metall oder die Legierung in der gewünschten Form erstarrt.Continuous casting molds are reusable and downwardly open molds for casting metals or alloys. For this purpose, the liquid metal or the liquid alloy is passed through the existing of cooled copper plates mold, where the metal or alloy solidifies in the desired shape.

Ein besonderes Problem beim Stranggießen besteht in einer hierfür vorteilhaften, gleichmäßigen und schonenden Kühlung der Kupfer-Rohrkokille. Hierzu wird Kühlmittel durch vorgefertigte Kühlmittelkanäle geleitet, wobei in der Regel Wasser als Kühlmittel verwendet wird. Dabei ist eine gleichmäßige Temperaturverteilung des Kühlmittels wünschenswert, damit die Kokille durch starke lokale Temperaturgradienten nicht beschädigt wird. Ferner weist der Guss bei einer konstanten Kühlleistung eine höhere Oberflächenqualität auf.A particular problem in continuous casting consists in this advantageous, uniform and gentle cooling of the copper tube mold. For this purpose, coolant is passed through prefabricated coolant channels, wherein water is usually used as a coolant. In this case, a uniform temperature distribution of the coolant is desirable so that the mold is not damaged by strong local temperature gradients. Furthermore, the casting has a higher surface quality at a constant cooling capacity.

Stranggießkokillen der eingangs genannten Art sind beispielsweise aus der EP 2 014 393 A1 sowie aus der EP 1 468 760 B1 bekannt. Als Verbindungsmittel zwischen dem Kokillenrohr und dem Stützmantel werden dort Verbindungsprofile beschrieben, wobei die Verbindungsprofile entlang der gesamten Umfangslinie in Längsrichtung angeordnet sind. Bei der Ausgestaltung gemäß der EP 2 014 393 A1 besitzt das einstückig am Kokillenrohr angeordnete Verbindungsprofil eine gerundete Nase, die von einer weiteren Nase einer Verbindungsleiste hintergriffen wird, die mit dem Stützmantel verbunden ist. Hierzu sind mehrere Befestigungsschrauben vorgesehen, die von außen den Stützmantel durchgreifen. Demgegenüber ist bei der Ausführungsform gemäß der EP 1 468 760 B1 vorgesehen, dass die Profilleisten am Kokillenrohr als T-Profilstücke oder als Schwalbenschwanz-Profilstücke ausgebildet sind, wobei das Profilstück an dem Stützmantel korrespondierend geformt ist, um eine entsprechende Verbindung zu schaffen.Continuous casting molds of the type mentioned are, for example, from the EP 2 014 393 A1 as well as from the EP 1 468 760 B1 known. As connecting means between the mold tube and the support jacket connecting profiles are described there, wherein the connection profiles are arranged along the entire circumferential line in the longitudinal direction. In the embodiment according to the EP 2 014 393 A1 has the integrally arranged on the mold tube connection profile has a rounded nose, which is engaged behind by a further nose of a connection bar, which is connected to the support shell. For this purpose, a plurality of fastening screws are provided, which pass through the support shell from the outside. In contrast, in the Embodiment according to the EP 1 468 760 B1 provided that the profile strips are formed on the mold tube as T-profile pieces or as dovetail profile pieces, wherein the profile piece is formed on the support jacket corresponding to create a corresponding connection.

Weitere Rohrkokillen, bei denen der Stützmantel bzw. ein Wasserkasten über einzelne Verbindungsmittel mit der Rohrkokille verbunden ist, werden in EP 0 987 073 A1 , WO 95/21036 und EP 0 978 336 A1 offenbart.Further pipe molds, in which the support casing or a water tank is connected via individual connecting means with the tubular mold, are in EP 0 987 073 A1 . WO 95/21036 and EP 0 978 336 A1 disclosed.

Nachteilig an den beschriebenen Kokillen ist zunächst, dass die Herstellung bzw. Bearbeitung relativ aufwendig ist, was die Herstellungskosten in die Höhe treibt. Zudem ist die Montage vergleichsweise kompliziert, da die jeweiligen Leisten zunächst parallel zueinander und anschließend in der richtigen Höhe ausgerichtet werden müssen, was sich als schwierig erwiesen hat. Besonders problematisch ist jedoch die Tatsache, dass im Bereich der Profilleisten eine reduzierte Kühlwirkung erfolgt, was zu den bereits angesprochenen lokalen starken Temperaturgradienten führt. Das wird auch dadurch verstärkt, dass bei den bekannten Lösungen die Kühlkanäle einseitig abgedeckt sind.A disadvantage of the described molds is first that the production or processing is relatively expensive, which drives the production costs in the air. In addition, the assembly is relatively complicated, since the respective strips must first be aligned parallel to each other and then at the correct height, which has proven to be difficult. Particularly problematic, however, is the fact that in the area of the profile strips a reduced cooling effect takes place, which leads to the already mentioned local strong temperature gradients. This is also reinforced by the fact that in the known solutions, the cooling channels are covered on one side.

Es ist daher die Aufgabe der vorliegenden Erfindung dort Abhilfe zu schaffen und eine Kokille vorzuschlagen, bei der eine möglichst konstante und gleichmäßige Kühlleistung entlang der gesamten Oberfläche geschaffen wird.It is therefore the object of the present invention to remedy this situation and to propose a mold, in which the most constant and uniform cooling performance along the entire surface is created.

Diese Aufgabe wird durch die Kokille nach Anspruch 1 gelöst, wobei erfindungsgemäß in den am Außenmantel der Kokille angeordneten rippenförmigen Stützprofilen mehrere beabstandete betreffende Stützprofile vollständig durchgreifende nutförmige Ausnehmungen mit Hinterschneidungen vorgesehen sind, in welche die Verbindungsmittel eingreifen, die zusätzlich einen schaftförmigen Hohlkörper mit einer inneren Gewindebohrung aufweisen, die eine Befestigungsschraube zur Fixierung des Stützmantels aufnimmt. Mit anderen Worten der Stützmantel besteht aus mehreren Stützmantelplatten, die mit dem Kokillenrohr mittelbar über Schraubverbindungen verbunden sind, die in den schaftförmigen Hohlkörper eingreifen, wozu dieser einen entsprechenden Gewindeabschnitt besitzt. Der Hohlkörper ist formschlüssig innerhalb von Ausnehmungen an den rippenförmigen Stützprofilen gelagert. Hierdurch können die Stützmantelplatten rasch und mit wenig Personalaufwand montiert werden, da die korrekte Positionierung bereits durch nur zwei Verbindungspunkte festgelegt ist und ein längsaxiales Verschieben der Stützmantelplatte gegenüber dem Kokillenrohr verhindert wird. Die übrigen Befestigungsschrauben können anschließend problemlos eingebaut werden.This object is achieved by the mold according to claim 1, wherein according to the invention in the arranged on the outer shell of the mold rib-shaped support profiles are provided a plurality of spaced respective support profiles completely sweeping groove-shaped recesses with undercuts, in which engage the connecting means, which in addition a shaft-shaped hollow body with an internal threaded bore have, which receives a fastening screw for fixing the support jacket. In other words, the support shell consists of several support shell plates, which are indirectly connected to the mold tube via screw that in the shaft-shaped hollow body engage, for which it has a corresponding threaded portion. The hollow body is positively mounted within recesses on the rib-shaped support profiles. As a result, the support jacket plates can be mounted quickly and with little manpower, since the correct positioning is already determined by only two connection points and a longitudinal axial displacement of the support shell plate is prevented from the mold tube. The remaining fixing screws can then be easily installed.

Ferner wird durch den schaftförmigen Hohlkörper mit der Gewindebohrung ein vergleichsweise langer Gewindeabschnitt geschaffen, so dass eine stabile Verbindung besteht. Das ist nicht der Fall, wenn die Gewindebohrungen unmittelbar in den Stützprofilen eingebracht werden würde, die möglichst flach ausgebildet sind und somit nur wenig Raum für einen Gewindeabschnitt bieten.Furthermore, a comparatively long threaded portion is created by the shaft-shaped hollow body with the threaded bore, so that a stable connection exists. This is not the case if the threaded holes would be introduced directly into the support profiles, which are formed as flat as possible and thus provide little room for a threaded portion.

Bevorzugte Ausführungsformen der vorliegenden Erfindung werden im Folgenden sowie in den Unteransprüchen angegeben.Preferred embodiments of the present invention are given below and in the subclaims.

Nach einer ersten vorteilhaften Ausführungsform der vorliegenden Erfindung sind die nutförmigen Ausnehmungen mit Hinterschneidungen und die hier eingreifenden Teile der Verbindungsmittel T- oder Schwalbenschwanz-Profile. Solche Profilquerschnitte lassen sich einfach, schnell und somit kostenschonend herstellen und liefern zudem einen optimalen Halt des Verbindungsmittels.According to a first advantageous embodiment of the present invention, the groove-shaped recesses with undercuts and here engaging parts of the connecting means T or dovetail profiles. Such profile cross-sections can be produced easily, quickly and thus cost-effectively and also provide optimum retention of the connecting means.

Um bei der Montage der Stützmantelplatten die Positionierung weiter zu erleichtern, besitzen die schaftförmigen Hohlkörper der Verbindungsmittel an einer Seite einen konischen Außenmantel, der als Zentrierhilfe für die aufzusetzende Stützmantelplatte dient. Ferner weist nach einer weiteren Ausgestaltung der Erfindung die Stützmantelplatte Durchbrechungen auf, die vorzugsweise Bohrungen sein können, in welche die schaftförmigen Hohlkörper der Verbindungsmittel im montierten Zustand hineinragen. Somit muss die Stützmantelplatte bei der Montage zunächst nur grob positioniert werden, so dass die Spitzen der Hohlkörper in die Durchbrechungen hineinragen. Bei einem anschließenden "Aufstecken" der Stützmantelplatte wird diese automatisch korrekt positioniert. Alternativ oder auch additiv hierzu könnten auch die Durchbrechungen innerhalb der Stützmantelplatten konisch ausgebildet sein.In order to further facilitate the positioning during assembly of the support jacket plates, the shaft-shaped hollow bodies of the connecting means have on one side a conical outer jacket which serves as a centering aid for the supporting jacket plate to be fitted. Furthermore, according to a further embodiment of the invention, the support shell plate openings, which may preferably be bores into which protrude the shaft-shaped hollow body of the connecting means in the assembled state. Thus, the support shell plate initially only needs to be roughly positioned during assembly, so that the tips of the hollow body protrude into the openings. In a subsequent "plugging" the support shell plate it is automatically positioned correctly. Alternatively or in addition to this, the openings could also be formed conically within the support jacket plates.

Damit die Stützmantelplatte fest mit dem Kokillenrohr verbunden werden kann, weisen die Durchbrechungen der Stützmantelplatte jeweils Einschnürungen mit einem Durchmesser auf, der zur Durchführung des Schraubenschaftes aber nicht des Schraubenkopfes ausgebildet ist. Vorzugsweise ruht der Schraubenkopf im montierten Zustand in einer Einsenkung der Stützmantelplatte.Thus, the support jacket plate can be firmly connected to the mold tube, the openings of the support jacket plate respectively constrictions with a Diameter, which is designed to carry out the screw shaft but not the screw head. Preferably, the screw head rests in the mounted state in a depression of the support jacket plate.

Nach einer ersten konkreten Ausgestaltung der vorliegenden Erfindung besteht die Kokille aus einem Kokillenrohr 1 und einem Stützmantel 2. Das Kokillenrohr 1 besitzt über den Umfang verteilte sich in Längsrichtung 4 erstreckende Stützprofile 3, so dass sich das Kokillenrohr 1 hierüber an dem Stützmantel 2 abstützt. Darüber hinaus sind ebenfalls in Längsrichtung 4 angeordnete Kühlkanäle 5 vorgesehen, durch die ein Kühlmittel strömt.According to a first concrete embodiment of the present invention, the mold consists of a mold tube 1 and a support shell 2. The mold tube 1 has distributed over the circumference extending in the longitudinal direction 4 supporting profiles 3, so that the mold tube 1 hereby supported on the support casing 2. In addition, also arranged in the longitudinal direction 4 cooling channels 5 are provided, through which a coolant flows.

In Fig. 2 ist eine Detailansicht einer Seite des Kokillenrohrs 1 mit den Stützprofilen 3 und den Kühlmittelkanälen 5 gezeigt. Dort und in der Detailansicht der Fig. 3 ist ferner zu erkennen, dass an den Stützprofilen 3 zumindest teilweise mehrere beabstandete nutförmige Ausnehmungen 6 mit Hinterschneidungen 7 vorgesehen sind. Hier greifen Verbindungsmittel 8 ein, die einen schaftförmigen Hohlkörper 9 mit einer inneren Gewindebohrung 10 besitzen, die eine (in Fig. 1 bis 3 nicht dargestellten) Befestigungsschraube aufnimmt. In der dargestellten Ausführungsform (Fig. 3) ist die nutförmige Ausnehmung 6 mit Hinterschneidungen 7 und die hier eingreifenden Teile 13 des Verbindungsmittels 8 T-förmig ausgebildet. Allerdings könnte auch eine Schwalbenschwanz-Verbindung oder eine andere formschlüssige Verbindung vorgesehen sein.In Fig. 2 a detail view of one side of the mold tube 1 with the support profiles 3 and the coolant channels 5 is shown. There and in the detail view of the Fig. 3 It can also be seen that at least partially a plurality of spaced groove-shaped recesses 6 are provided with undercuts 7 on the support profiles 3. Here engage connecting means 8, which have a shaft-shaped hollow body 9 with an inner threaded bore 10 having a (in Fig. 1 to 3 not shown) Mounting screw receives. In the illustrated embodiment ( Fig. 3 ) is the groove-shaped recess 6 with undercuts 7 and the engaging here parts 13 of the connecting means 8 T-shaped. However, a dovetail connection or another positive connection could also be provided.

Wie der Fig. 1 zu entnehmen ist, sind an dem Stützmantel 2, der vier Stützmantelplatten 11 bis 11'" besitzt, mehrere Durchbrechungen 12 vorgesehen, durch die jeweils eine Befestigungsschraube greift. Um ein Aufschieben der Stützmantelplatten 11 bis 11"' zu erleichtern, ist der schaftförmige Hohlkörper 9 nach oben hin konisch ausgebildet. Alternativ hierzu könnte auch die Durchbrechung 12 konisch ausgebildet sein, womit ebenfalls eine Positionierungshilfe geschaffen ist. Darüber hinaus sind an den Seiten der Stützmantelplatten 11 bis 11"' Zinken 17 ausgebildet, so dass die Stützmantelplatten 11 bis 11"' über eine Verzinkung miteinander verbunden sind, was eine besonders stabile Verbindung darstellt.Again Fig. 1 5, a plurality of apertures 12 are provided on the supporting jacket 2, which has four supporting jacket plates 11 to 11 ', through which a fastening screw engages conically formed at the top. Alternatively, the opening 12 may be conical, which also provides a positioning aid is created. In addition, on the sides of the support shell plates 11 to 11 '' tines 17 are formed, so that the support shell plates 11 to 11 '' are connected to each other via a galvanizing, which is a particularly stable connection.

In den Fig. 4 und 5 ist jeweils ein einzelnes Verbindungsmittel 8 mit dem schaftförmigen Hohlkörper 9 und einem T-förmigen einzuführenden Teil 13, jeweils in einer Front- und einer Seitenansicht, dargestellt.In the 4 and 5 is in each case a single connecting means 8 with the shaft-shaped hollow body 9 and a T-shaped part to be inserted 13, each in a front and a side view shown.

Fig. 6 zeigt in einer schematischen Darstellung eine einzelne Verbindung zwischen einer Stützmantelplatte 11 und einem Stützprofil 3. Hierbei greift der schaftförmige Hohlkörper 9 in die Durchbrechung 12 ein, wobei der schaftförmige Hohlkörper 9 eine Befestigungsschraube 14 aufnimmt. Damit der Kopf 15 der Befestigungsschraube 14 nicht durch die Durchbrechung 12 hindurchrutscht, ist die Einschnürung 16 angeordnet. Eine Vielzahl solcher Verbindungen liefert eine stabile und leicht zu montierende Befestigung der Stützmantelplatten 11-11"', die alle zusammen den Stützmantel 2 bilden. Fig. 6 shows a schematic representation of a single connection between a support shell plate 11 and a support section 3. Here, the shaft-shaped hollow body 9 engages in the opening 12, wherein the shaft-shaped hollow body 9 receives a fastening screw 14. So that the head 15 of the fastening screw 14 does not slip through the opening 12, the constriction 16 is arranged. A variety of such compounds provides a stable and easy-to-install attachment of the support shell plates 11-11 "', all together form the support shell 2.

Aufgrund der thermischen Ausdehnung, welche das Kokillenrohr 1 beim Stranggießen erfährt, und der unterschiedlichen Ausdehnung zwischen Kokillenrohr 1 und Stützmantel 2 muss ein gewisses Spiel zwischen den schaftförmigen Hohlkörpern 9 und den entsprechenden Bohrungen 12 in der Stützmantelplatte 11-11"' einkalkuliert werden.Due to the thermal expansion, which experiences the mold tube 1 during continuous casting, and the different expansion between mold tube 1 and support shell 2, a certain play between the shaft-shaped hollow bodies 9th and the corresponding holes 12 in the support shell plate 11-11 "'calculated.
