Abstract
Description
Die Erfindung betrifft eine Stranggießkokille, insbesondere zum Gießen von Knüppel- oder Vorblocksträngen, deren Gießrohr von einem Kokillengehäuse mit Spaltabstand umgeben ist, in den ein Kühlmediumstrom zuführbar und wieder abführbar ist.The invention relates to a continuous casting mold, in particular for casting billets or blooms, the pour tube from a mold housing with Gap distance is surrounded, in which a coolant flow can be fed and again is dissipatable.
Beim Stranggießen von Metallen, insbesondere von Stahl, erstarrt der flüssige
Stahl im Verlauf des Gießprozesses von außen nach innen in der Stranggießkokille.
Die Erstarrung erfolgt näherungsweise hyperbelförmig nach der Gleichung
Um die sich daraus ergebende Erstarrungskurve schon in der Stranggießkokille zu
berücksichtigen, kann in der Stranggießkokille die Regulierung der Wärmeabfuhr
über örtlich abgestimmte Wassergeschwindigkeiten erfolgen. Im Meniskus des
Kokillen-Badspiegels muss ein Maximum an Wärme abgeführt werden, während
am Austritt der Stranggießkokille eine entsprechend geringere Wärmemenge abzuführen
ist.When continuously casting metals, in particular steel, the liquid steel solidifies in the continuous casting mold from outside to inside during the casting process. The solidification is approximately hyperbolic according to the equation
In order to take the resulting solidification curve into account in the continuous casting mold, the heat dissipation in the continuous casting mold can be regulated via locally coordinated water speeds. A maximum of heat must be dissipated in the meniscus of the mold bath level, while a correspondingly smaller amount of heat must be dissipated at the outlet of the continuous casting mold.
Aus der DE-OS 14 83 556 ist eine Kühlzonen-Einteilung auf die Kokillenhöhe vorgesehen, wobei jeder der übereinanderliegenden Kühlzonen eine eigene Zu- und Abführleitung zugeteilt ist. DE-OS 14 83 556 provides a cooling zone division to the mold height, each of the superimposed cooling zones has its own access and Discharge line is allocated.
Aus der DE-AS 1 608 059 ist es bekannt, das Kühlmedium in senkrechten Kanälen von unten nach oben durch den Kühlkasten der Kokille zu leiten und einen hohen Gegendruck aufzubauen.From DE-AS 1 608 059 it is known that the cooling medium in vertical channels from the bottom up through the cooling box of the mold and a high Build up back pressure.
Der Erfindung liegt die Aufgabe zugrunde, die Geschwindigkeit des Kühlmediums im Kühlkanal des Kühlmantels einer Stranggießkokille über die Geometrie des Kühlmediumleitmantels zu steuern.The invention has for its object the speed of the cooling medium in the cooling channel of the cooling jacket of a continuous casting mold on the geometry of the To control the coolant jacket.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, dass der Kühlmedium-Spalt derart über die Kokillenhöhe unterschiedlich breit ist, dass im oberen Kokillenbereich der Kühlmedium-Spalt eng ist, entsprechend einer hohen Kühlmedium-Geschwindigkeit, und im unteren Kokillenbereich relativ breit ist, entsprechend einer relativ niedrigeren Kühlmedium-Geschwindigkeit. Dadurch kann durch diese geometrische Gestaltung der Kühlmedienkanäle eine Regulierung der Wassergeschwindigkeiten und damit der Wärmeabfuhr erreicht werden.The object is achieved according to the invention in that the cooling medium gap is so wide across the mold height that in the upper Mold area of the cooling medium gap is narrow, corresponding to a high cooling medium speed, and is relatively wide in the lower mold area, accordingly a relatively lower cooling medium speed. This allows through this geometric design of the cooling media channels regulates the water speeds and thus the heat dissipation can be achieved.
Dabei entspricht zumindest die senkrechte Kontur der äußeren Kühlmediumspalt-Wandung einer Negativform der Erstarrungslinie im Gießstrang die von oben nach unten verläuft. Diese Negativform führt zu kleinen Kühlmedium-Geschwindigkeiten im unteren Kokillenbereich und durch den engen Spalt zu hohen Kühlmedium-Geschwindigkeiten im oberen Kokillenbereich.At least the vertical contour corresponds to the outer cooling medium gap wall a negative form of the solidification line in the casting strand from above runs down. This negative form leads to low cooling medium speeds too high in the lower mold area and due to the narrow gap Coolant speeds in the upper mold area.
Eine weitere Verbesserung der geometrischen Kühlspaltformen ergibt sich dadurch, dass der Kühlmedium-Spalt in Eckenbereichen zusätzlich vergrößert ist. Da die Ecken des Gießstrangs im Vergleich zu den Flächen weniger Wärmeabfuhr erfordern, kann hier die Kühlmedium-Geschwindigkeit etwas verringert werden. A further improvement of the geometrical cooling gap shapes results from that the cooling medium gap is additionally enlarged in corner areas. There the corners of the casting strand compared to the surfaces less heat dissipation the cooling medium speed can be reduced somewhat here.
Eine ähnliche Verbesserung stellt dar, dass der Kühlmedium-Spalt über die Kokillenbreitseiten und / oder die Kokillenlängsseiten unterschiedlich breit ist, wobei der enge Spalt jeweils in der Seitenmitte vorgesehen ist. Dadurch wird in den Seitenmitten durch die engen Spalte wiederum eine größere Kühlmedium-Geschwindigkeit und an den Ecken durch die Ausbauchungen eine geringere Geschwindigkeit erzielt.A similar improvement is that the cooling medium gap over the broadside of the mold and / or the long sides of the mold are of different widths, the narrow gap is provided in the center of the page. This will be in the middle of the page due to the narrow gaps, a higher cooling medium speed and a lower speed at the corners due to the bulges achieved.
Für die Fertigung ist es vorteilhaft, dass das Gießrohr zylindrisch ausgebildet ist und das Kokillengehäuse (der Wasserleitmantel) die senkrechte Kontur aufweist.It is advantageous for production that the pouring tube is cylindrical and the mold housing (the water guiding jacket) has the vertical contour.
Eine günstige Strömung bei kleinem Strömungswiderstand entsteht ferner dadurch, dass die Eckbereiche einer horizontalen Kontur jeweils ovalförmig ausbauchend ausgebildet sind.A favorable flow with a small flow resistance also arises from that the corner areas of a horizontal contour each bulging oval are trained.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung schematisch dargestellt und wird nachfolgend näher erläutert.In the drawing, an embodiment of the invention is shown schematically and is explained in more detail below.

Die Stranggießkokille dient insbesondere zum Gießen von Knüppel- oder Vorblocksträngen
und ist mit einem Gießrohr 1 und einem Kokillengehäuse 2 versehen,
das einen Wasserleitmantel 2a bildet. Das Kokillengehäuse 2 liegt mit
Spaltabstand 3 um das Gießrohr 1. Das Kühlmedium 4, wie üblich Wasser oder
Wasser mit Zusätzen, wird in den Kühlmedium-Spalt 5 auf der Kokillenhöhe 6 im
unteren Kokillenbereich 6b zugeführt und unter Erwärmung beim Hochsteigen im
oberen Kokillenbereich 6a wieder in Pfeilrichtung nach erfolgter Wärmeaufnahme
abgeführt. The continuous casting mold is used in particular for casting billet or blooms
