Description

Stranggießkokillecontinuous casting
Die Erfindung betrifft eine Stranggießkokille mit den Gießquerschnitt begrenzenden Kupferplatten, in denen einem Wasserkasten zugewandt, Kühlmittelkanäle für das Kühlwasser senkrecht zur Gießquerschnittsebene verlaufen, und jeweils einem pro Gießquerschnittsseite auf den Kupferplatten dicht befestigtem Wasserkasten, an den die Kühlmittelkanäle der Kupferplatten mit einem Sammelvorlauf und einem Sammelrücklauf angeschlossen sind.The invention relates to a continuous casting mold with the casting cross-section delimiting copper plates, in which a water tank facing, coolant channels for the cooling water run perpendicular to the casting cross-sectional plane, and in each case a water box tightly fixed per casting cross-section side on the copper plates, to which the coolant channels of the copper plates with a collecting flow and a collecting return are connected.
Eine derartige Stranggießkokille ist aus der DE 198 35 111 A1 bekannt. Zur Kühlung solcher Stranggießkokillen werden Wasserkästen eingesetzt. Die Wasserkästen übernehmen die Aufgabe, das Kokillenkühlwasser an die Kupferplatten zu führen und gleichzeitig die Kupferplatten zu stützen. Alle wasserführenden Teile, insbesondere der Wasserkasten, werden aus Edelstahl hergestellt. Daher werden die kompletten Wasserkasten-Innenwände und Wasserkasten-Außenwände aus Edelstahl gefertigt. Dadurch entstehen erhebliche Materialkosten, die die Stranggießkokille verteuern. Es ist bisher nicht gelungen, das System der Wasserkästen zu ändern und den Aufwand an Edelstahl einzuschränken.Such a continuous casting mold is known from DE 198 35 111 A1. Water boxes are used to cool such continuous casting molds. The water boxes take on the task of leading the mold cooling water to the copper plates and at the same time supporting the copper plates. All water-carrying parts, especially the water tank, are made of stainless steel. For this reason, the complete inner and outer water box walls are made of stainless steel. This results in considerable material costs, which make the continuous casting mold more expensive. So far, it has not been possible to change the system of the water boxes and to limit the expenditure on stainless steel.
Der Erfindung liegt die Aufgabe zugrunde, den Anteil von Edelstahl an Wasserkästen zu senken und dadurch die Stranggießkokillen wirtschaftlicher herzustellen.The invention has for its object to reduce the proportion of stainless steel in water tanks and thereby manufacture the continuous casting molds more economically.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass für einen profilierten Gießquerschnitt eine Kupferformplatte dem Gießquerschnittsverlauf angepasst ist und Kühlmittelbohrungen in Gießrichtung verlaufend zur Kühlmittelführung und quer verlaufend angeschlossene Sammelvorlauf- und Sammelrücklauf-Bohrungen aufweist, die in zumindest zwei, separaten, kanalförmigen Wasserkästen aus Edelstahl münden, wobei die Wasserkästen jeweils unmittelbar und dicht von außen auf die Kupferformplatte aufgesetzt sind. Bei einer derartigen Stranggießkokille werden die Kokillenplatten nicht wie bei allen anderen Formaten üblich durch nach hinten offene Kühlschlitze mit Kühlwasser versorgt, sondern das Kühlwasser wird durch Kühlbohrungen geleitet, die am oberen und unteren Rand der Kupferplatte durch Sammelbohrungen über die verhältnismäßig kleinen Edelstahl-Wasserkästen mit Kühlwasser betrieben werden.The object is achieved according to the invention in that for a profiled pouring cross-section, a copper mold plate is adapted to the pouring cross-sectional profile and has coolant bores running in the pouring direction for the coolant guidance and transverse collection feed and collection return bores connected in at least two, separate, channel-shaped bores Stainless steel water boxes open, the water boxes being placed directly and tightly from the outside onto the copper plate. In such a continuous casting mold, the mold plates are not supplied with cooling water through cooling slots that are open to the rear, as is usual with all other formats, but rather the cooling water is passed through cooling bores, which are at the top and bottom of the copper plate through collecting holes through the relatively small stainless steel water boxes with cooling water operate.
Die Erfindung ist daher besonders geeignet, neben Gießsträngen mit rechteckigem oder quadratischem Querschnitt profilierte Gießstränge zu erzeugen. So ist es nach weiteren Merkmalen vorteilhaft, dass der Profilgießquerschnitt der Kupferplatten einem Vorprofil-Gießstrang angepasst ist.The invention is therefore particularly suitable for producing casting strands in addition to casting strands having a rectangular or square cross section. According to further features, it is advantageous that the profile casting cross section of the copper plates is adapted to a pre-profile casting strand.
Eine solche Anwendung ergibt sich nach anderen Merkmalen vorteilhaft dadurch, dass der Profilgießquerschnitt der Kupferformplatte ein dog-bone-Profil bildet.According to other features, such an application advantageously results from the fact that the profile casting cross section of the copper mold plate forms a dog-bone profile.
Für die Zufuhr und Abfuhr und für die Verteilung des Kühlwassers ist nunmehr vorgesehen, dass der Wasserkasten für eine Kupferformplatte aus zwei beab- standeten und quer zur Gießrichtung verlaufenden, aus Edelstahl gefertigten länglichen Kanalgehäusen besteht, die mittels einer Trägerplatte seitlich verbunden sind und auf der Kupferformplatte dicht aufliegen. Die Trägerfunktion wird hier durch die Trägerplatte aus einem Werkstoff, der nicht teuer sein muss, erfüllt, da im mittleren Bereich kein Kühlmedium geführt wird. Außerdem kann weiter an Edelstahl eingespart werden, weil die Kanalgehäuse nur an drei Seiten Wandungen aufweisen.For the supply and discharge and for the distribution of the cooling water, it is now provided that the water box for a copper molded plate consists of two spaced-apart and transverse to the casting direction, made of stainless steel elongated channel housings, which are laterally connected by means of a carrier plate and on the copper molded plate lie tight. The carrier function is fulfilled here by the carrier plate made of a material that does not have to be expensive, since no cooling medium is carried in the middle area. Stainless steel can also be saved further because the duct housing has walls on only three sides.
Dabei kann eine Trägerplatte aus Normalstahl, d.h. aus einem weitgehend unlegierten Stahl gefertigt sein. Eine weitere Ausgestaltung sieht vor, dass innerhalb der Breite eines Kanalgehäuses jeweils mehrere Verbindungsbohrungen von der Kupferformplatte in dem jeweiligen Kanalgehäuse münden. Die Länge des Kanalgehäuses kann dabei die Anzahl der aufzunehmenden Verbindungsbohrungen bestimmen.A carrier plate can be made from normal steel, ie from a largely unalloyed steel. A further embodiment provides that within the width of a channel housing, a plurality of connection bores from the copper molded plate each open into the respective channel housing. The length of the channel housing can determine the number of connection bores to be accommodated.
Je nach der äußeren Form der Kupferformplatte kann deren Verlauf festgelegt werden. Hierzu wird vorgeschlagen, dass von der Kupferformplatte schräg oder senkrecht Verbindungsbohrungen in das Kanalgehäuse verlaufen.Depending on the outer shape of the copper plate, its course can be determined. For this purpose, it is proposed that connecting bores run obliquely or vertically from the copper molded plate into the channel housing.
Die Kühlung wird anders als bei an der Kühlwasserseite mit Schlitzen versehene Kupferplatten derart vorgenommen, dass die Verbindungsbohrungen jeweils an mehrere um das dog-bone-Profil angeordnete, senkrecht zur Gießrichtung verlaufende Kühlmittelbohrungen angeschlossen sind.In contrast to copper plates provided with slots on the cooling water side, the cooling is carried out in such a way that the connecting bores are each connected to a plurality of coolant bores arranged around the dog-bone profile and running perpendicular to the casting direction.
Die Herstellung der Kühlmittelkanäle wird nach der weiteren Erfindung dadurch vorgenommen, dass die in Gießrichtung verlaufenden Kühlmittelbohrungen in der Kupferformplatte durchgehend hergestellt sind und mittels Abschlussstopfen zumindest einseitig verschlossen sind.The manufacture of the coolant channels is carried out according to the further invention in that the coolant bores running in the casting direction are made continuously in the copper mold plate and are closed at least on one side by means of end plugs.
Schließlich ist vorgesehen, dass auf den Kanalgehäusen jeweils an den Enden ein Anschlussflansch angeordnet ist. Die Anschlussflansche können aus Edelstahl bestehen, können jedoch auch aus einem Normalstahl hergestellt sein.Finally, it is provided that a connection flange is arranged at the ends of the channel housings. The connection flanges can be made of stainless steel, but can also be made of normal steel.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, das nachfolgend näher erläutert wird.In the drawing, an embodiment of the invention is shown, which is explained in more detail below.

Fig. 1 einen horizontalen Querschnitt durch die Stranggießkokille undFig. 1 shows a horizontal cross section through the continuous casting mold and
Fig.2 einen vertikalen Querschnitt in der Ebene B -B aus Fig. 1. Die Stranggießkokille 1 besitzt einen Gießquerschnitt 1a am Eingang, der in der Gießquerschnittsebene 1 b gebildet ist. Der Gießquerschnitt 1 a wird durch Kupferplatten 2 begrenzt, an deren dem Gießquerschnitt 1a abgewandter Seite ein Wasserkasten 3 angeordnet ist. In dem Wasserkasten 3 sind Kühlmittelkanäle 4 innerhalb der Kupferplatten 2 eingearbeitet, die senkrecht zur Gießquerschnittsebene 1b verlaufen. Für jede Kupferplatte 2 ist ein solcher Wasserkasten 3 vorhanden, um die aus dem Gießquerschnitt 1a abzuführende Wärme des Gießmetalls in das Kühlwasser zu übertragen. An dem Wasserkasten ist ein Sammelvorlauf 6 und ein Sammelrücklauf 7 vorgesehen, die das kalte Kühlwasser den Kühlmittelkanälen 4 zuführen oder das erwärmte Kühlwasser von den Kühlmittelkanälen 4 einsammeln.2 shows a vertical cross section in the plane B - B from FIG. 1. The continuous casting mold 1 has a casting cross section 1 a at the entrance, which is formed in the casting cross section plane 1 b. The pouring cross section 1 a is delimited by copper plates 2, on the side of which facing away from the pouring cross section 1 a, a water box 3 is arranged. Coolant channels 4 are incorporated in the water box 3 within the copper plates 2, which run perpendicular to the casting cross-sectional plane 1b. Such a water box 3 is provided for each copper plate 2 in order to transfer the heat of the casting metal to be dissipated from the casting cross section 1a into the cooling water. On the water tank, a collection flow 6 and a collection return 7 are provided, which feed the cold cooling water to the coolant channels 4 or collect the heated cooling water from the coolant channels 4.
Für einen profilierten Gießquerschnitt 1a, worunter nicht nur rechteckige oder quadratische Gießquerschnitte 1 a zu verstehen sind, ist eine Kupferformplatte 2a vorgesehen, die mit ihrer inneren Seite der Gießquerschnittsseite 5 angepasst ist. Die Kupferformplatte 2a besitzt keine Kühlschlitze, wie an solchen Kupferplatten 2 sonst üblich sind, sondern Kühlmittelbohrungen 9, die parallel zur Gießrichtung 10 verlaufen. Die Anordnung der Kühlmittelbohrungen 9 folgt dem Gießquerschnittsverlauf 8. Außerdem sind quer verlaufende Sammelvorlauf-Bohrungen 6a und Sammelrücklauf-Bohrungen 7a eingearbeitet, die mit dem Wasserkasten 3 in Verbindung stehen. Um an Edelstahl zu sparen, sind jeweils zwei separate, kanalförmige Wasserkästen 3 aus Edelstahl vorhanden, wobei die Wasserkästen 3 jeweils unmittelbar und dicht von außen auf die Kupferformplatte 2a aufgesetzt sind. Der Querschnitt der Kanalgehäuse 13 ist U-förmig, so dass an der Dichtseite der Kanal offen ist und auch dadurch noch an Edelstahl gespart wird.For a profiled pouring cross-section 1a, which does not only mean rectangular or square pouring cross-sections 1 a, a molded copper plate 2a is provided, the inner side of which is adapted to the pouring cross-section side 5. The copper mold plate 2a does not have cooling slots, as is otherwise customary on such copper plates 2, but rather coolant bores 9, which run parallel to the casting direction 10. The arrangement of the coolant bores 9 follows the pouring cross-section 8. In addition, transverse collection feed bores 6a and collection return bores 7a are incorporated, which are connected to the water tank 3. In order to save on stainless steel, there are two separate, channel-shaped water boxes 3 made of stainless steel, the water boxes 3 each being placed directly and tightly from the outside onto the copper mold plate 2a. The cross section of the channel housing 13 is U-shaped, so that the channel is open on the sealing side and this also saves on stainless steel.
Diese Ausführung des Wasserkastens 3 eignet sich besonders für Profilgießquerschnitte 11 , wie z.B. das gezeichnete dog-bone-Profil 11a. In der Stranggießkokille 1 wird dadurch ein Vorprofil-Gießstrang 12 erzeugt (Fig. 2). Der Wasserkasten 3 besteht für eine Kupferformplatte 2a jeweils aus zwei beabstandet an den Kokillenenden angeordneten länglichen Kanalgehäusen 13, die aus Edelstahl geformt sind. Die Kanalgehäuse 13 sind jeweils mittels einer Trägerplatte 14 seitlich verbunden und liegen auf der Kupferformplatte abgedichtet und befestigt auf. Dabei kann die Trägerplatte 14 aus Normalstahl, d.h. aus einfachem Kohlenstoffstahl bestehen. Innerhalb der Breite 13a eines solchen Kanalgehäuses 13 mündet jeweils eine Vielzahl von Verbindungsbohrungen 15, die in der Kupferformplatte 2a verlaufen. Die Verbindungsbohrungen 15 können sowohl schräg nach oben oder unten oder, wie gezeichnet (Fig. 1) parallel zur Gießquerschnittsebene 1 b angeordnet sein. Die Verbindungsbohrungen 15 sind an die in entsprechender Anzahl vorhandenen, um das dog-bone- Profil 11a angeordnete, senkrecht zur Gießrichtung 10 verlaufende Kühlmittelbohrungen 9 angeschlossen (Fig. 1 ).This design of the water box 3 is particularly suitable for profile casting cross sections 11, such as the dog-bone profile 11a shown. As a result, a pre-profile casting strand 12 is produced in the continuous casting mold 1 (FIG. 2). For a copper molded plate 2a, the water box 3 consists in each case of two elongated channel housings 13 which are arranged at a distance from the mold ends and which are formed from stainless steel. The channel housing 13 are each laterally connected by means of a carrier plate 14 and lie sealed and fastened on the molded copper plate. The carrier plate 14 can consist of normal steel, ie of simple carbon steel. Within the width 13a of such a channel housing 13, a plurality of connection bores 15 each open, which run in the copper mold plate 2a. The connecting bores 15 can be arranged obliquely upwards or downwards or, as drawn (FIG. 1), parallel to the casting cross-sectional plane 1b. The connecting bores 15 are connected to the corresponding number of coolant bores 9 which are arranged around the dog-bone profile 11a and run perpendicular to the casting direction 10 (FIG. 1).
Die Herstellung der Kühlmittelbohrungen 9 kann in Gießrichtung 10 in der Kupferformplatte 2a durchgehend erfolgen, wobei eine Seite ( in Fig. 2 die obere Seite) der Stranggießkokille 1 mittels eines Abschlussstopfens 16 verschlossen wird.The coolant bores 9 can be produced continuously in the casting direction 10 in the copper mold plate 2a, one side (the upper side in FIG. 2) of the continuous casting mold 1 being closed by means of an end plug 16.
An den Kanalgehäusen 13 sind außerdem (nicht notwendigerweise aus Edelstahl bestehende) Anschlussflansche 17 an dem ersten Ende 13b und an dem zweiten Ende 13c des Kanalgehäuses 13 befestigt. On the channel housing 13, connection flanges 17 (not necessarily made of stainless steel) are also fastened at the first end 13b and at the second end 13c of the channel housing 13.
