Description
Die Erfindung betrifft eine Stranggießkokille zum Gießen von Strängen, vorzugsweise aus Stahl, bestehend aus Kokillenplatten und Wasserkasten, die miteinander verbunden sind und zwischen denen eine Wasserkühlung mit Hilfe von Wasserführungskanälen aufgebaut ist, wobei die Wasserführungskanäle in der der Kokillenplatte zugewandten Seite des Wasserkastens angeordnet sind und nicht in der Kokillenplatte.The invention relates to a continuous casting mold for casting strands, preferably made of steel, consisting of mold plates and water box, which together are connected and between which water cooling with the help of Water channels are built, the water channels in the Chill plate facing side of the water tank are arranged and not in the mold plate.
Kokillenplatten - vorzugsweise bestehend aus Kupfer für das Stranggießen von Brammen, Dünnbrammen, Vorblöcken und Profilen - werden auf ihrer Rückseite mit Wasser gekühlt und sind auf einen Stahlwasserkasten aufgeschraubt.Mold plates - preferably consisting of copper for the continuous casting of Slabs, thin slabs, blooms and profiles - are on their back cooled with water and screwed onto a steel water tank.
So wird das Wasser z.B. bei Dünnbrammenkokillen durch Kanäle einer Breite von
ca. 5 mm vom Ausgang der Kokille (Boden) in Richtung Gießspiegel vertikal zur
Oberkante der Kokille geleitet. Das Wasser wird mit einem Druck zwischen 5 bis
15 bar und Strömungsgeschwindigkeiten von 5 bis 15 m/s durch die Wasserführungskanäle
geleitet, um den Wärmestrom von bis zu 4 MW/m2 an der Phasengrenze
Cu-Platte/Wasser ohne eine Störung des Wärmeübergangs durch Gasblasenbildung
aufnehmen und abtransportieren zu können.For example, in the case of thin slab molds, the water is directed vertically to the upper edge of the mold through
Diese Wasserkanäle werden in der Regel in die Cu-Platte auf der dem Wasser zugewandten Cu-Plattenseite eingearbeitet. Dies geschieht in den mechanischen Werkstätten mit NC-gesteuerten Werkzeugmaschinen, die viel Zeit dafür benötigen und sehr kostenintensiv sind.These water channels are usually in the copper plate on the water facing Cu plate side incorporated. This happens in the mechanical Workshops with NC-controlled machine tools that take a lot of time and are very expensive.
Außerdem ist zu bemerken, daß speziell im Falle von Dünnbrammen Kokillen nach DE 34 00 220 C2 - mit einer auf der dem Stahl zugewandten Seite konkaven Form bzw. mit einer auf der dem Wasser zugewandten Seite konvexen Form - das Einbringen von Wasserführungskanälen noch maschinen- und kostenaufwendiger ist als bei planparallelen Cu-Platten, wie sie bei konventionellen Brammenkokillen zum Einsatz kommen.It should also be noted that, especially in the case of thin slabs, molds according to DE 34 00 220 C2 - with a concave on the side facing the steel Shape or with a convex shape on the side facing the water - the introduction of water guide channels even more machine and costly than with plane-parallel Cu plates, as is the case with conventional slab molds are used.
Das Einbringen der Wasserführungskanäle ist zudem aus Sicht der Lebensdauer der Cu-Platten, die als Schleißteile anzusehen sind, ökonomisch gesehen nicht sinnvoll.The introduction of the water channels is also from the point of view of life the Cu plates, which are to be regarded as wearing parts, are not economically meaningful.
In dem japanischen Dokument JP-A-61 146 444 wird eine Kokillenplatte zum kontinuierlichen Gießen von Strängen bestehend aus Stahl gezeigt. Die Kokillenplatte ist in Sandwich-Bauweise aufgebaut, bestehend aus der den Gießstrang führenden Kupferplatte, die mit einer Trageplatte über eine Schraubverbindung in Verbindung steht. In der Trageplatte sind Wasserführungskanäle angeordnet. Zwecks Verbindung der Kupferplatte mit der Trageplatte sind auf der der Trageplatte zugewandten Seite der Kupferplatte Verdickungen vorgesehen, die in entsprechende Einformungen in der Trageplatte eingreifen. In diese Verdickungen werden Schrauben eingeschraubt, um Kupferplatte und Trageplatte miteinander fest zu verbinden. Die Wasserführungskanäle sind in der Trageplatte angeordnet und nicht in der Kupferplatte.In Japanese document JP-A-61 146 444, a mold plate for continuous Casting strands of steel shown. The mold plate is built in sandwich construction, consisting of the leading the casting strand Copper plate connected to a support plate via a screw connection stands. Water guide channels are arranged in the support plate. For the purpose of Connection of the copper plate to the support plate are on the side facing the support plate Side of the copper plate provided thickenings, which in corresponding Intervene in the support plate. Be in these thickenings Screws screwed in to secure the copper plate and support plate together connect. The water channels are arranged in the support plate and not in the copper plate.
In dem PCT-Dokument WO-A-9521036, insbesondere Fig. 11, wird eine Kupferplatte in Sandwichbauart dargestellt. Auf einer Stahlplatte befindet sich eine Kupferplatte, auf der der Gießstrang geführt wird. In der Stahlplatte und nicht in der Kupferplatte sind Kühlkanäle eingelassen. Die Kühlkanäle werden von der Kupferplatte abgedeckt und die Verbindung zwischen Stahlplatte und Kupferplatte wird mittels einer Schraubverbindung hergestellt. Das Abdichten zwischen der Stahlplatte und der Kupferplatte erfolgt mittels Weichlot.In the PCT document WO-A-9521036, in particular Fig. 11, a copper plate is used shown in sandwich design. There is a copper plate on a steel plate, on which the casting strand is guided. In the steel plate and not in the Cooling channels are embedded in the copper plate.

Sealing between the steel plate and the copper plate is made using soft solder.
Ausgehend vom zuvor genannten Stand der Technik ist es die Aufgabe der Erfindung, eine technisch sinnvollere Lösung zu finden, die es erlaubt, die Cu-Platten, die als Verschleißteile anzusehen sind, einfacher und kostengünstiger zu gestalten und insbesondere die Verbindung der Kupferplatte mit dem Wasserkasten aus Stahl zu optimieren.Starting from the aforementioned prior art, it is the object of the invention to find a technically more sensible solution that allows the Cu plates, which are to be regarded as wearing parts, easier and cheaper to design and especially the connection of the copper plate to the water tank Optimize steel.
Eine unerwartete Lösung für diese beschriebene Aufgabe stellen die in den Patentansprüchen 1 bis 11 beschriebenen Merkmale dar.An unexpected solution to this described task are presented in the claims 1 to 11 described features.

Die Figur 1 stellt einen Horizontalschnitt durch die Breitseite 1 einer Dünnbrammenkokille
mit Gießtrichter 2 oder mit einer dem flüssigen Stahl zugewandten
konkaven Kokillenform dar.1 shows a horizontal section through the broad side 1 of a thin slab mold
with
Die Kokillenbreitseite besteht aus
- einer Cu-
Platte 3 mit einer Abmessung von beispielsweise 1,6 x 1,2 m und einer Dicke von 0,02 m, die auf beiden Seiten glatte und zueinanderparallele Oberflächen 4 und 5 aufweist, - einem
Stahlwasserkasten 6, der mitKühlwasserführungskanälen 7 versehen ist, die demkonvexen Profil 5 der Cu-Platte 3 in horizontaler und vertikaler Richtung bis zumKokillenausgang 8 folgen.
- a
Cu plate 3 with a dimension of, for example, 1.6 x 1.2 m and a thickness of 0.02 m, which has smooth and 4 and 5 on both sides,parallel surfaces - a
steel water tank 6, which is provided with coolingwater guide channels 7, which follow theconvex profile 5 of theCu plate 3 in the horizontal and vertical direction to themold exit 8.
Der Wasserkasten 6 besteht aus einer Stahlplatte 9, die mit den Wasserführungskanälen
7, einer Wanddicke oder Kammdicke 7.1 und einer Kanalbreite 7.2 versehen
ist, und dem eigentlichen Wasserführungskasten mit seinen Stegen 10.The
Die Stege 10 können entweder mit der Stahlplatte 9 verschweißt 11 sein oder z.B.
mit Schrauben 12, die in die Cu-Breitseitenplatte 3 eingelassen sind, verbunden
sein, die beispielsweise über Muttern 13 oder gefederte Keile mit der Rückseite 14

Diese Vorrichtungsanordnung gilt selbstverständlich auch für planparallele Kokillenplatten von konventionellen Brammenkokillen sowie Vorblockkokillen und Kokillen für Profile, wie z.B. "Dogbones" oder ähnliche Stranggießformate. Of course, this device arrangement also applies to plane-parallel mold plates of conventional slab molds as well as pre-block molds and molds for profiles, e.g. "Dogbones" or similar continuous casting formats.
Vorteile der Endung sind eine konstruktive Vereinfachung des Verschleißteiles
"Cu-Platte" und die Verlagerung des "intelligenten" (regelbaren bzw. steuerbaren)
Teils der Kokille mit ihren Wasserführungskanälen 7 auf dem nicht verschleißenden
Kokillenteil des Stahlwasserkastens 6 mit seiner Stahlplatte 9.The advantages of the extension are a design simplification of the wearing part
"Cu plate" and the shift of the "intelligent" (adjustable or controllable)
Part of the mold with its
Weitere Vorteile sind darin zu sehen, daß das Einbringen der Ankerschrauben 12
in die Cu-Platte 3 für die nötige Kraftübertragung nicht so tief erfolgen muß, da die
Wasserführungskanäle in der Stahlplatte 9 des Stahlwasserkastens 6 und nicht in
die Cu-Platte 3 eingelassen sind.Further advantages can be seen in the fact that the insertion of the
Hierdurch kann der Cu-Plattenrohling dünner und/oder die Kupferplattendicke kleiner bzw. die Lebensdauer der Cu-Platte über mehr Bearbeitungszyklen länger werden, wodurch zusätzlich die Materialbeschaffungskosten bemerkenswert gesenkt werden können.This can make the Cu plate blank thinner and / or the copper plate thickness shorter or the service life of the Cu plate longer over more machining cycles are reduced, which also significantly reduces material procurement costs can be.
Außerdem gibt die erfinderische Lösung die Möglichkeit, daß die Wasserführungskanäle
7, bedingt durch die besseren Werkstoffeigenschaften des Stahles gegenüber
Kupfer, breiter werden können, wodurch eine bessere und gleichförmigere
Kühlung der Cu-Platte 3 sichergestellt wird.In addition, the inventive solution gives the possibility that the
Die Wasserkanäle im Kupfer haben beispielsweise bisher eine Breite von 5 mm
und eine Kammdicke von 5 mm und führen damit zu einer Wasserbedeckung von
50%. Eine höhere Wasserbedeckung, d.h. eine geringere relative Kammdicke 7.1,
kann mit dem Werkstoff Stahl in der Stahlplatte 9 des Wasserkastens erreicht
werden, da die Gefahr des Wegknickens des Stahlkamms 7.1 einmal durch die
geringere thermomechanische Belastung und zum zweiten durch die höhere mechanische
Belastbarkeit von Stahl wesentlich geringer wird. So kann die Wasserkanalbreite
7.2 beispielsweise 16 mm und die Kammdicke 4 mm betragen. Diese
Anordnung würde zu einer Wasserbedeckung von 80% führen, die wiederum zu
einer verbesserten und gleichmäßigeren Kühlung führt, und die es erlaubt, die
Kühlwassergeschwindigkeiten und/oder den Kühlwasserdruck zu reduzieren.The water channels in copper, for example, have so far been 5 mm wide
and a comb thickness of 5 mm and thus lead to a water coverage of
50%. A higher water coverage, i.e. a lower relative comb thickness 7.1,
can be achieved with the steel material in the
Eine Reduktion des Kühlwasserdruckes würde wiederum dünnere Cu-Plattendicken
zulassen, da die Gefahr des Ausbauchens der Cu-Platte 3 bzw. der
Cu-Plattenoberfläche aufgrund des reduzierten Wasserdruckes geringer wird. Die
geringe Cu-Plattendicke führt wiederum zu geringeren Oberlächentemperaturen
in der dem flüssigen Stahl zugewandten Seite 4 - hot face - der Cu-Platte 3, die
die Lebenszeit der Cu-Platte erhöht.A reduction in the cooling water pressure would in turn lead to thinner Cu plate thicknesses
allow, since the risk of bulging the

mit dem Unterschied, daß die Verbindungsplatte 9 nicht aus Stahl, sondern aus
einer Sandwichplatte in der Weise aufgebaut ist, daß auf der Stahlplatte 9.1 des
Wasserkastens 6 eine Zwischenplatte 9.2 aus Kupfer oder aus einer Kupferlegierung
aufliegt, in die ihrerseits die Wasserführungskanäle 7 eingearbeitet sind. Die
