Abstract

A continuous casting mold for casting strands, preferably of steel, includes mold plates and water boxes, and a connecting plate for connecting each mold plate to one of the water boxes. A water cooling system is formed by water conduits between the mold plates and the water boxes, wherein the water conduits are arranged in a side of the water box facing the mold plate and not in the mold plate. The water box and the connecting plate of the water box are joined together by connecting screws and nuts, wherein the connecting screws are arranged in the mold plate and the nuts are arranged on the water box. The connecting screws have internal cooling ducts and the internal cooling ducts are connected to the water conduits.

Description

StranggießkokilleContinuous casting mold
Die Erfindung betrifft eine Sranggießkokille 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.The invention relates to a continuous casting mold for casting strands, preferably made of steel, consisting of mold plates and a water tank, which are connected to one another and between which a water cooling system is built up using water guide channels.
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.Chill plates - preferably made of copper for the continuous casting of slabs, thin slabs, blooms and profiles - are cooled with water on the back and are 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 - 15 bar und Strömungsgeschwindigkeiten von 5 - 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.So the water is z. B. in thin slab molds through channels of a width of about 5 mm from the exit of the mold (bottom) in the direction of the casting level vertically to the upper edge of the mold. The water is passed through the water ducts at a pressure between 5 - 15 bar and flow velocities of 5 - 15 m / s to reduce the heat flow of up to 4 MW / m 2 at the phase boundary Cu plate / water without disturbing the heat transfer To be able to pick up and remove gas bubbles.
Diese Wasserkanäle werden bisher 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 have so far been incorporated into the copper plate on the copper plate side facing the water. This is done in the mechanical workshops with NC-controlled machine tools, which take a lot of time and are very cost-intensive.
Außerdem ist zu bemerken, daß speziell im Falle von Dünnbrammen Kokillen (DE 3400220) - 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 raaschinen- und kostenaufwendiger ist als bei planparallelen Cu-Platten, wie sie bei konventionellen Bramraenkokillen zum Einsatz kommen.It should also be noted that, especially in the case of thin slabs, molds (DE 3400220) - with a concave shape on the side facing the steel or with a convex shape on the side facing the water - the introduction of water guiding channels is even more machine-intensive and costly than with plane-parallel ones Cu plates, such as those used in conventional bramra molds.
Das Einbringen der Wasserführungskanäle ist zudem aus Sicht der Lebensdauer der Cu-Platten, die als Verschleißteile anzusehen sind, ökonomisch gesehen nicht sinnvoll.From the point of view of the lifespan of the copper plates, which are to be regarded as wearing parts, the introduction of the water channels is not economically sensible.
Aufgabe der Erfindung ist es nun, eine technisch sinnvollere Lösung zu finden, die es erlaubt, die Cu-Platten, die als Ver- schleißteile anzusehen sind, einfacher und kostengünstiger zu gestalten.The object of the invention is now to find a technically more sensible solution which makes it possible to make the Cu plates, which are to be regarded as wearing parts, simpler and less expensive.
Eine unerwartete Lösung für diese beschriebene Aufgabe stellen die in den Patentansprüchen 1 bis 13 beschriebenen Merkmale dar.The features described in claims 1 to 13 represent an unexpected solution to this problem.
Die Erfindung zeichnet sich durch eine Gestaltung der Stranggießkokillen aus, bei der die Wasserführungskanäle in der der Kokillenplatte zugewandten Seite des Wasserkastens (6) angeordnet sind und nicht - wie bisher - in der Kokillenplatte (3).The invention is characterized by a design of the continuous casting molds in which the water guide channels are arranged in the side of the water box (6) facing the mold plate and not - as previously - in the mold plate (3).
Figur 1 und Figur 2 dienen zur Veranschaulichung der folgenden beispielhaften Beschreibung der Erfindung.FIG. 1 and FIG. 2 serve to illustrate the following exemplary description of the invention.
Figur 1 Darstellung einer Breitseitenkokillenplatte mit Wasser- kästen für das Gießen von Dünnbrammen als Horizontalschnitt in der oberen Hälfte der Kokille.Figure 1 Representation of a broadside die plate with water boxes for the casting of thin slabs as a horizontal section in the upper half of the mold.
Figur 2 Darstellung der Kokillenplatte wie in Figur 1, jedoch mit einer Verbindungsplatte in Sandwichbauweise.Figure 2 Representation of the mold plate as in Figure 1, but with a connecting plate in sandwich construction.
Figur 3 Eine vergrößerte Darstellung des Ausschnitts A in Figur 2.Figure 3 is an enlarged view of section A in Figure 2.
Die Figur 1 stellt einen Horizontalschnitt durch die Breitseite (1) einer Dünnbramraenkokille mit Gießtrichter (2) oder mit einer dem flüssigen Stahl zugewandten konkaven Kokillenform dar. Die Kokillenbreitseite besteht aus1 shows a horizontal section through the broad side (1) of a thin Bramraenkokille with casting funnel (2) or with a concave mold shape facing the liquid steel. The wide mold side consists of
• 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 zueinander parallele Oberflächen (4) und (5) aufweist,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 mutually parallel surfaces (4) and (5) on both sides,
• einem Stahlwasserkasten (6), der mit Kühlwasserführungskanälen (7) versehen ist, die dem konvexen Profil (5) der Cu- Platte (3) in horizontaler und vertikaler Richtung bis zum Kokillenausgang (8) folgen.• A steel water tank (6), which is provided with cooling water guide channels (7) that follow the convex profile (5) of the Cu plate (3) in the horizontal and vertical directions to the mold exit (8).
Der Wasserkasten (6) besteht aus einer Stahlplatte (9), die mit den Wasser-führungskanälen (7), einer Wanddicke oder Kammdicke (7.1) und einer Kanalbreite (7.2) versehen ist, und dem eigentlichen Wasserführungskasten mit seinen Stegen (10).The water tank (6) consists of a steel plate (9), which is provided with the water guide channels (7), a wall or ridge thickness (7.1) and a channel width (7.2), and the actual water guide box with its webs (10).
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) des Wasserkastens verspannt sind.The webs (10) can either be welded (11) to the steel plate (9) or z. B. with screws (12), which are embedded in the Cu broad side plate (3), which are clamped, for example, via nuts (13) or spring-loaded wedges with the back (14) of the water tank.
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, such as. B. "Dogbones" or similar continuous casting formats.
Vorteile der Erfindung 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)-Advantages of the invention are a constructive simplification of the wearing part "Cu plate" and the relocation of the "intelligent" (regulatable or controllable) part of the mold with its water guide channels (7) on the non-wearing part of the mold of the steel water tank (6) with its steel plate ( 9) -
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 anchor bolts (12) into the Cu plate (3) for the necessary power transmission does not have to be as deep as the Water channels in the steel plate (9) of the steel water tank (6) and not in the Cu plate (3).
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.As a result, the Cu plate blank can be thinner and / or the copper plate thickness can be smaller, or the service life of the Cu plate can be longer over more machining cycles, which can also significantly reduce the cost of material procurement.
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 water guide channels (7), due to the better material properties of the steel compared to copper, can be wider, thereby ensuring better and more uniform cooling of the copper plate (3).
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 Kühlwasser- druck zu reduzieren.The water channels in copper, for example, have previously been 5 mm wide and 5 mm thick, thus leading to a water coverage of 50%. Higher water coverage, i.e. H. A lower relative comb thickness (7.1) can be achieved with the material steel in the steel plate (9) of the water tank, since the risk of the steel comb buckling away (7.1) is due to the lower thermomechanical load and the higher mechanical load capacity of steel becomes much lower. For example, the water channel width (7.2) can be 16 mm and the comb thickness 4 mm. This arrangement would result in water coverage of 80%, which in turn leads to improved and more uniform cooling, and which allows the cooling water speeds and / or the cooling water pressure to be reduced.
Eine Reduktion des Kühlwasserdruckes würde wiederum dünnere Cu- Plattendicken zu-lassen, da die Gefahr des Ausbauchens der Cu- Platte (3) bzw. der Cu-Plattenoberflache aufgrund des reduzierten Wasserdruckes geringer wird. Die geringe Cu-Plattendicke führt wiederum zu geringeren Oberflächentemperaturen in der dem flüssigen Stahl zugewandten Seite (4) - hot face - der Cu-Platte (3), die die Lebenszeit der Cu-Platte erhöht. Figur 2 bezieht sich mit allen wesentlichen Merkmalen und Vorteilen auf Figur 1 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 Zwischenplatte 9.2 ist mittels der Spannschrauben 12 zwischen Kokillenplatte 3 und Wasserkasten 6 so eingespannt, daß keine Nachteile bezgl . der Wärmeübertragung enstehen können.A reduction in the cooling water pressure would in turn allow thinner copper plate thicknesses, since the risk of bulging the copper plate (3) or the copper plate surface is lower due to the reduced water pressure. The low copper plate thickness in turn leads to lower surface temperatures in the side (4) - hot face - of the copper plate (3) facing the liquid steel, which increases the service life of the copper plate. Figure 2 refers to all the essential features and advantages of Figure 1 with the difference that the connecting plate 9 is not made of steel, but from a sandwich plate in such a way that on the steel plate 9.1 of the water tank 6, an intermediate plate 9.2 made of copper or from a Copper alloy rests, in which in turn the water channels 7 are incorporated. The intermediate plate 9.2 is clamped between the mold plate 3 and the water tank 6 by means of the tensioning screws 12 in such a way that no disadvantages with respect to. heat transfer can arise.
Figur 3 zeigt einen vergrößerten Ausschnitt A aus Figur 2 mit einer Kühlverbindung 16 zu den Wasserführungskanälen 7 und mit einem in der Verbindungsschraube 12 angeordnetem Kühlkanal 15, die jeweils nur eine Prinzipdarstellung sein sollen, dessen Detailausführung vom Fachmann ohne weiteres ausgeführt werden kann .FIG. 3 shows an enlarged detail A from FIG. 2 with a cooling connection 16 to the water guide channels 7 and with a cooling channel 15 arranged in the connecting screw 12, which are each intended to be only a basic illustration, the detailed execution of which can be carried out by a person skilled in the art.
Die Erfindung hat somit einen unerwartete, multiplizierende, positive Wirkung auf die Strangqualität, die Kokillenhaltbarkeit und die Betriebskosten. The invention thus has an unexpected, multiplying, positive effect on the strand quality, the mold durability and the operating costs.
