Abstract

The invention concerns a continuous-casting device having a mould which oscillates in the casting direction, the mould being mounted on springs extending across the casting direction and fixed at each end and the mould being connected to a hydraulic oscillatory drive. The device proposed is characterized in that the hydraulic oscillatory drives are designed as servo cylinders, the servo cylinders (3) being located beside the mould in the plane of a longitudinal cross-section through the mould, and the servo cylinders (3) being firmly fixed without play to a support frame (1) and to the mould.

Description

Einrichtung zum Stranggießen von Stahl Device for the continuous casting of steel
Die Erfindung betrifft eine Einrichtung zum Stranggießen von Stahl gemäß Gattungsbegriff des Anspruches 1.The invention relates to a device for the continuous casting of steel according to the preamble of claim 1.
Eine derartige Einrichtung ist aus der DE-OS 22 48 066 bekannt. Die Einrichtung besteht aus einer als Blockkokille ausgebildeten Stranggießkokille, so daß insbesondere bei Brammenkokillen keine Verstellung der Brammenbreite möglich ist. Dadurch wird die Lagerhaltung sehr aufwendig, da für jedes Strangformat eine besondere Kokille erforderlich ist. Außerdem müssen die die Kokille tragenden Federn und die Antriebsaggregate für die Oszillation sehr groß dimensioniert v/erden, da die gesamte Kokille, also die eigentlichen formgebenden Wände einschließlich des Kühlsystems getragen und bewegt werden müssen.Such a device is known from DE-OS 22 48 066. The device consists of a continuous casting mold designed as a block mold, so that in particular in the case of slab molds it is not possible to adjust the slab width. This makes warehousing very complex since a special mold is required for each strand format. In addition, the springs carrying the mold and the drive units for the oscillation must be dimensioned very large, since the entire mold, that is to say the actual shaping walls, including the cooling system, must be carried and moved.
Aus der EP 0468 607 AI ist es bereits bekannt, die formgebenden Wände von dem gekühlten Halterahmen zu trennen, um eine Entlastung des Antriebes und möglichst gering dimensionierte Federelemente zu verwirklichen. Andererseits ist aus der DE 35 43 790 C2 bereits ein gesteuertes hydraulisches AntriebsSystem für Stranggießkokillen bekannt, mit dem eine verkantungsfreie Führung der Kokille gegenüber dem gegossenen Strang angestrebt wird.From EP 0468 607 AI it is already known to separate the shaping walls from the cooled holding frame in order to relieve the load on the drive and to achieve the smallest possible spring elements. On the other hand, a controlled hydraulic drive system for continuous casting molds is already known from DE 35 43 790 C2, with which a tilt-free guidance of the mold relative to the cast strand is aimed for.
Der Erfindung liegt die Aufgabe zugrunde, eine weitere Vereinfachung und Verbesserung der Oszillation der Kokille zu erreichen.The invention has for its object to achieve a further simplification and improvement of the oscillation of the mold.
Die Aufgabe wird bei einer Stranggießkokille der gattungsgemäßen Art gelöst mit den Merkmalen des kennzeichnenden Teils des Anspruches 1. Erfinderische Ausgestaltungen des Lösungsprinzips sind in den Unteransprüchen angegeben.The object is achieved in a continuous casting mold of the generic type with the features of the characterizing part of claim 1. Inventive configurations of the solution principle are specified in the subclaims.
Anhand der Zeichnungen, die das Prinzip der Erfindung wiedergeben, soll die Erfindung näher erläutert werden.The invention will be explained in more detail with reference to the drawings, which represent the principle of the invention.

Fig. 4 is a sketch of the kinematics of the device according to the invention.
Die Fig. 1 bis 3 zeigen einen Tragrahmen 1, für eine aus Breitseitenplatten 10 und Sch alseittenplatten 11 bestehende Stranggießkokille. Mit 13 sind Kompensatoren für die Breitseiten- Kühlung bezeichnet. Die Schmalseitenplatten 11 sind zwischen den Breitseitenplatten 10 über Spanneinrichtungen (nicht dargestellt) in ihrer Lage gehalten. Sie sind an einem Befestigungsblock 12 für Wasserkästen und Schmalseitenverstelleinrichtungen 20 zur Breitenverstellung befestigt. Der Befestigungsblock 12 ist mit Federn 8 über Klemm-Mittel 9 verbunden. Die Federn 8 erstrecken sich oberhalb und unterhalb des Befestigungsblockes 12 und sind jeweils mit ihren freien Enden in einem Spannblock 7 befestigt. Die Spannblöcke 7 sind auf Befestigungsböcken 6 angeordnet, die Bestandteil des Tragrahmens 1 sind. Unter den Befestigungsblöcken 12 sind Hydraulikzylinder 3 mit ihren Kolbenstangen 4 befestigt. Die Hydraulikzylinder 3 sind auf Konsolen 2 des Tragrahmens 1 fest angeordnet. Das obere, an den Befestigungsblöcken 12 angreifende Ende der Kolbenstange 4 ist als Federelement 5 ausgebildet, so daß bei Kokillen mit gekrümmter Längsachse und dementsprechend einer Kokillenoszil lationsbewegung auf einem Bogen und einer tangentialen Bewegung der Kolbenstange 4 Auslenkungen des Angriffspunktes der Kolbenstange 4 durch die bogenförmige Kokillenbewegung von den Federelementen 5 aufgenommen werden und damit die Funktionstüchtigkeit der Hydraulikzylinder 3 nicht beeinträchtigt wird.1 to 3 show a supporting frame 1, for a continuous casting mold consisting of broad side plates 10 and side plates 11. With 13 compensators for broadside cooling are designated. The narrow side plates 11 are held in their position between the broad side plates 10 by means of tensioning devices (not shown). They are on a mounting block 12 for water tanks and narrow side adjustment devices 20 Width adjustment attached. The mounting block 12 is connected to springs 8 via clamping means 9. The springs 8 extend above and below the fastening block 12 and are each fastened with their free ends in a clamping block 7. The clamping blocks 7 are arranged on mounting blocks 6, which are part of the support frame 1. Hydraulic cylinders 3 are fastened with their piston rods 4 under the mounting blocks 12. The hydraulic cylinders 3 are fixed on brackets 2 of the support frame 1. The upper, on the mounting blocks 12 engaging end of the piston rod 4 is designed as a spring element 5, so that in molds with a curved longitudinal axis and accordingly a Kokillenoszil lationsbewegung on an arc and a tangential movement of the piston rod 4 deflections of the point of attack of the piston rod 4 by the arcuate mold movement are absorbed by the spring elements 5 and thus the functionality of the hydraulic cylinders 3 is not impaired.
Wie in den Fig. 3 und 4 dargestellt, wobei die Darstellung der Fig. 4 zur Verdeutlichung der Situation in einem verzerrten Maßstab erfolgt ist, sind die oberen und unteren Federn 8 derart gegeneinander geneigt angeordnet, daß sich ihre Fluchtlinien in einer durch den Krümmungsmittelpunkt 15 der Kokille bzw. der Kokillenlängsachse gelegten Geraden schneiden. Insbesondere in Fig. 4 wird deutlich, daß der Befestigungsblock 12 an den Federn 8 mittels der Klemm-Mittel 9 nicht in der Mitte zwischen den Spannblöcken 7 einer Feder angelenkt ist, sondern etwas außermittig zum Krümmungsmittelpunkt 15 hin verschoben angeordnet ist. In Fig. 4 ist die gekrümmte Längsschnittebene 14 in die bogenäußere Kokillenbreitseite 10' gelegt, die also gleichzeitig der bogenäußeren, hinteren Strangkante und der Anlagenbezugsebene entspricht. Der Schnittpunkt 16 der unteren Federn 8 mit der Längsschnittebene 14 ist also der Befestigungspunkt der Kolbenstange 4 an der Kokille. Die durchgezogenen Linien stellen die Lage der Kokille in der Montageposition dar. Nach der Montage ergibt sich eine statische Durchsenkung der Kokille bzw. der Federn, wobei diese Lage nicht einskizziert ist. Sie liegt jedoch zwischen den "Betriebslagen" der Kokille (gestrichelte Linien), wobei die Lage der Kokille am oberen Totpunkt eines Oszillationshubes mit 17 und der untere Umkehrpunkt mit 18 bezeichnetAs shown in FIGS. 3 and 4, the illustration of FIG. 4 being made on a distorted scale to clarify the situation, the upper and lower springs 8 are arranged inclined relative to one another in such a way that their alignment lines lie in one through the center of curvature 15 cut the straight line or the longitudinal axis of the mold. In particular, in Fig. 4 it is clear that the mounting block 12 on the springs 8 by means of the clamping means 9 is not articulated in the middle between the clamping blocks 7 of a spring, but is arranged somewhat eccentrically to the center of curvature 15. In Fig. 4, the curved longitudinal section plane 14 is placed in the outside of the mold broad side 10 ', which thus corresponds to the outside of the rear strand edge and the system reference plane. The intersection 16 of the lower springs 8 with the longitudinal section plane 14 is thus the point of attachment of the piston rod 4 to the mold. The Solid lines represent the position of the mold in the assembly position. After assembly, the mold or springs are lowered statically, this position not being sketched out. However, it lies between the "operating positions" of the mold (dashed lines), the position of the mold at the top dead center of an oscillation stroke being 17 and the bottom reversal point being 18
Es ist also offensichtlich, daß es sich im vorbezeich¬ neten Fall um eine Einrichtung handelt, bei der die Federstarke auf die Masse der Kokille derart abgestimmt ist, daß die Einrichtung im Resonanzbereicht schwingt. Derartige, sogenannte Resonanzkokillen , oszillieren also bauartbedingt um die Lage ihrer statischen Durch¬ senkung. Dabei bewegen sich die kokillenseitigen Schnittpunkte naherungsweise auf Geraden, die Tangenten an den Gießbogen im Schnittpunkt mit den Federachsen bilden. Der dadurch, insbesondere bei mittiger Anlenkung der Kokille an die Federn entstehende Führungsfehler wachst mit zunehmender statischer Durchsenkung, größer werdenden Hubamplituden sowie abnehmendem Gießradius. Nach der in Fig. 4 dargestellten Lösung, die gleichzeitig die bevorzugte Ausführungslösung zur Minimierung dieses "Führungsfehlers" darstellt, wird durch die vorbeschriebene Verschiebung der Schnittpunkte 16 auf den Krümmungsmittelpunkt 15 hin erreicht, daß eine resultierende Bewegung der Schnittpunkte eine Bahnkurve ergibt, die praktisch mit dem Gießradius identisch ist. Wenn auch bereits die im Hauptanspruch beschriebene Erfindung zu hervorragenden Oberflächengüten des Stranges führt, insbesondere durch Verringerung der Tiefe der sogenannten Hubmarken, wird diese verbesserte Oberfläche bei der bevorzugten Ausführungsform auch bei Anlagen erreicht, die mit kleinen Gießradien, großen Hubhöhen und hoher Frequenz der Oszillation betrieben werden. It is therefore obvious that in the above-mentioned case it is a device in which the spring force is matched to the mass of the mold in such a way that the device vibrates in the resonance range. Such so-called resonance molds therefore oscillate due to their design around the position of their static sag. The mold-side intersection points move approximately on straight lines that form tangents to the casting arch at the intersection point with the spring axes. The resulting guide error, particularly when the mold is articulated to the springs, grows with increasing static countersinking, increasing stroke amplitudes and decreasing casting radius. According to the solution shown in FIG. 4, which at the same time represents the preferred embodiment for minimizing this "guiding error", the above-described displacement of the intersection points 16 towards the center of curvature 15 ensures that a resultant movement of the intersection points results in a trajectory curve that is practically the same the casting radius is identical. Even if the invention described in the main claim leads to excellent surface qualities of the strand, in particular by reducing the depth of the so-called lifting marks, this improved surface is also achieved in the preferred embodiment in systems which operate with small casting radii, large lifting heights and high oscillation frequency become.
