Description
Die Erfindung betrifft eine flüssigkeitsgekühlte Kokille, insbesondere in einer Anlage zum Elektroschlakkenumschmelzen von Metallen, z. B. von Stählen, mit den Gießhohlraum der Kokille begrenzenden Platten.The invention relates to a liquid-cooled mold, in particular in a system for electric furnace remelting of metals, e.g. B. of steels, with the casting cavity of the mold delimiting plates.
Cj oße flüssigkeitsgekühlte Kokillen, insbesondere Solche zur Herstellung von Gußblöcken bzw. -strängen mit quadratischen, rechteckigen oder anderen mehrek kigen Querschnitten, lassen sich leicht aus Platten zusammensetzen, die durch Schrauben miteinander verbunden sind. An den Stoßstellen der in der eben erwähnten Weise angefertigten Kokillen entstehen jedoch — infolge der beim Kühlen von heißen Metallschmelzen, z. B. von Stahlschmelzen, in den Platten auftretenden Wärmespannungen — Spalte, durch die heiße Metallschmelze bzw. Schlacke austrittCj oße liquid-cooled molds, in particular Such for the production of cast blocks or strands with square, rectangular or other mehrek square cross-sections, can be easily assembled from panels, which are connected to each other by screws. At the joints in the one just mentioned However, wisely made molds arise - as a result of the cooling of hot metal melts, z. B. of molten steel, occurring in the plates Thermal stresses - gaps through which hot molten metal or slag emerges
Der Erfindung liegt die Aufgabe zugrunde, den eben angeführten Nachteil zu vermeiden und eine aus Platten und anderen Teilen zusammengesetzte flüssigkeitsgekühlte Kokille zu schaffen, an deren Stoßstellen, trotz der Einwirkung von heißer Metallschmelze und Schlacke auf die Platten, keine schädlichen Spalte entstehen. Erfindungsgemäß wird dies bei einer Kokille der eingangs genannten Art dadurch erreicht daß zwischen je zwei benachbarten Platten je ein Zwischenstück vorgesehen ist, das die dem Gießhohlraum zugewandten Flächen der Platten in in Längsrichtung derThe invention is based on the object to avoid the disadvantage mentioned and a liquid-cooled one composed of plates and other parts To create ingot mold at their joints, despite the action of hot molten metal and Slag on the plates, no harmful crevices are created. According to the invention, this is the case with a mold of the type mentioned achieved in that between each two adjacent plates there is an intermediate piece it is provided that the surfaces of the plates facing the casting cavity in the longitudinal direction of the
is Kokille verlautenden Randbereichen überdecktis covered by the edge areas indicating the mold
Weitere Einzelheiten der erfindungsgemäßen Kokille gehen aus den Unteransprüchen 2 bis 8 hervor. Die nachstehende Beschreibung betrifft ein Ausführungsbeispiel, das durch die Zeichnung in schematischer Dar- stellung veranschaulicht ist. Die Zeichnung zeigt einen Teil eines Querschnittes einer Kokille, die für eine Anlage zum Elektroschlackenumschmelzen von Stählen vorgesehen ist.Further details of the mold according to the invention emerge from subclaims 2 to 8. The following description relates to an exemplary embodiment which is illustrated in a schematic representation by the drawing. The drawing shows part of a cross section of a mold which is provided for a system for electroslag remelting of steels.
Innerhalb einer einen Mantelteil und radial angeordnete Versteifungsrippen Γ aufweisenden Halterung 1 sind acht gleiche, aus Kupfer bestehende Platten 2 vorgesehen. Diese sind an der Halterung 1 mittels nicht dargestellter Schrauben befestigt. Zwischen je zwei benachbarten Platten 2 ist je ein Zwischenstück 3 vorhanden. das einen annähernd T-förmigen Querschnitt aufweist, jedes Zwischenstück 3 befindet sich mit seinem Steg 4 zwischen je zwei benachbarten Platten 2 und liegt mit seinem Flansch S an deren den Gießhohlraum 10 begrenzenden ebenen Flächen 2' in in Längsrichtung der Kokille (d. h senkrecht zur Bildebene) verlaufenden Randbereichen ·2" fest an. Die Breite b des Steges 4 ist kleiner als der minimale Abstand a dieser Platten 2. Die dem Gießhohlraum 10 zugewandte Fläche 3' des jeweiligen Zwischenstückes 3 ist nach außen hin gewölbt.Eight identical plates 2 made of copper are provided within a holder 1 having a casing part and radially arranged stiffening ribs Γ. These are attached to the bracket 1 by means of screws, not shown. An intermediate piece 3 is provided between every two adjacent plates 2. which has an approximately T-shaped cross-section, each intermediate piece 3 is located with its web 4 between each two adjacent plates 2 and lies with its flange S on their flat surfaces 2 'delimiting the casting cavity 10 in the longitudinal direction of the mold (i.e. perpendicularly The width b of the web 4 is smaller than the minimum distance a of these plates 2. The surface 3 'of the respective intermediate piece 3 facing the casting cavity 10 is curved outwards.
Hierbei ist der Winkel * zwischen der dem Gießhohlraum 10 zugewandten Fläche 3' des jeweiligen Zwischenstückes 3 und der an sie angrenzenden Fläche des letzteren mindestens etwa 30°, vorzugsweise 45 bis 90°. Jedes Zwischenstück 3 ist mittels senkrecht zu seinem Flansch 5 angeordneter Sechskantschrauben 6 an der Halterung 1 befestigt Zwischen je einem Kopf 7 dieser Schrauben 6 und der Halterung l sind je zwei Tellerfedern 8 vorgesehen. Jedes Zwischenstück 3 weist je einen und jede Platte 2 jeweils mehrere im Querschnitt kreisförmige, vorzugsweise in Längsrichtung der Kokille verlaufende Kanäle 9 zum Hindurchleiten des Kühlmittels, z. B. von Wasser, auf. Der Gießhohlraum 10 der eben beschriebenen Kokille hat im wesentlichen einen regelmäßigen Achteckquerschnitt.Here is the angle * between that of the mold cavity 10 facing surface 3 'of the respective intermediate piece 3 and the adjacent surface of the the latter at least about 30 °, preferably 45 to 90 °. Each intermediate piece 3 is by means of perpendicular to his Flange 5 arranged hexagonal screws 6 attached to the bracket 1 between each head 7 of these Screws 6 and the bracket l are provided with two disc springs 8 each. Each intermediate piece 3 has each one and each plate 2 each have a plurality of circular cross-section, preferably in the longitudinal direction of the mold extending channels 9 for passing the coolant, for. B. of water. The casting cavity 10 of the The mold just described has essentially a regular octagonal cross-section.
Kokillen, deren Gießhohlräume andere, z. B. annähernd quadratische oder rechteckige Querschnitte haben sollen, können ebenfalls gemäß der Erfindung ausgeführt werden.Molds, the casting cavities of which other, z. B. approximately square or rectangular cross-sections can also be carried out according to the invention will.
Bei der erfindungsgemäßen Kokille können die den Gießhohlraum begrenzenden Flächen der Platten auch uneben, z. B. gewölbt, ausgeführt sein.In the mold according to the invention, the surfaces of the plates delimiting the casting cavity can also be used uneven, e.g. B. arched, executed.
Die erfindungsgemäße Kokille eignet sich nicht nur für Anlagen zum Elektroschlackenumschmelzen von Metallen, sondern beispielsweise auch für Stranggießanlagen. The mold according to the invention is not only suitable for systems for electroslag remelting Metals, but also, for example, for continuous casting plants.
