Abstract
The invention relates to the use of a hardenable copper alloy containing 0.1 % to 0.5 % beryllium and 0.5 % to 2.0 % nickel for the production of broad side plates for thin slab continuous casting molds at casting speeds of at least 2 to 6 m/min and higher.
Description
Verwendung einer aushärtbaren Kupferlegierung für KokillenUse of a hardenable copper alloy for molds
Die Erfindung betrifft die Verwendung einer aushartbaren Kupferlegierung für Kokillen, insbesondere zur Herstellung von Breitseitenplatten für Dunnbrammen- StranggießkokillenThe invention relates to the use of a hardenable copper alloy for molds, in particular for the production of broad side plates for thin slab casting molds
Beim Stand der Technik werden Kokillenbreitseitenplatten für Dunnbrammenanla- gen und insbesondere für CSP (Compact Strip Productιoπ)-Anlagen aus Kupferlegierungen wie CuCrZr (Kupfer Chrom Zirkon) oder CuAg (Kupfer Silber) hergestellt Dabei hat sich eine CuAg-Legierung für CSP-Kokillenplatten aufgrund seiner vergleichsweise hohen Dehnung bei steigenden Temperaturen als vorteilhaft erwiesenIn the prior art, mold wide side plates for thin slab systems and in particular for CSP (compact strip product) systems are produced from copper alloys such as CuCrZr (copper chromium zirconium) or CuAg (copper silver). Because of this, a CuAg alloy for CSP mold plates has been produced comparatively high elongation with increasing temperatures has proven to be advantageous
Kokillenbreitseitenplatten aus CuAg bzw CuCrZr sind jedoch nicht in der Lage, die im Badspiegeibereich des Gießmetalles herrschenden hohen Temperaturspannungen aufzunehmen und neigen dazu, in diesem Bereich Risse in den Platten zu bilden, wobei insbesondere CuCrZr zu besonders früher Rißbildung tendiert Diese Rißbildung ist dann das Ausfallkπteπum für die Kokillenbreitseitenplatten und verursacht hohe Reparatur- und Ersatzkosten für den Betreiber einer StranggießanlageHowever, mold wide side plates made of CuAg or CuCrZr are not able to absorb the high temperature tensions in the bath level of the cast metal and tend to form cracks in the area in this area, whereby CuCrZr in particular tends to form cracks particularly early. This crack formation is then the failure point for the mold wide side plates and causes high repair and replacement costs for the operator of a continuous caster
Es wurde beobachtet, daß CuAg trotz geringerer Zugfestigkeit nur deshalb eine verminderte Rißbildung aufweist, weil es infolge erhöhter Dehnfahigkeit bei hohen Temperaturen in der Kokillenplatte in der Lage ist, Spannungen abzubauen, und weil die vergleichsweise hohe Wärmeleitfähigkeit deren mittlere Betriebstemperatur niedriger halt
Für die Schmalseitenplatten von Dunnbrammen-Kokillen ist es beim Stand der Technik üblich, CuCrZr mit ca 125 HB-Harte einzusetzen, wobei deren seitliche Kontaktflachen zur Erhöhung der Harte vernickelt sindIt has been observed that CuAg, despite its lower tensile strength, only shows reduced crack formation because it is able to relieve stress in the mold plate as a result of increased extensibility at high temperatures, and because the comparatively high thermal conductivity keeps its mean operating temperature lower For the narrow side plates of thin slab molds it is customary in the prior art to use CuCrZr with approximately 125 HB hardness, the lateral contact surfaces of which are nickel-plated to increase the hardness
Das Ausfallkπteπum der Schmalseitenplatten ist im Unterschied zu den Breitsei- tenplatten nicht die Rißbildung, sondern der Verschleiß bzw Abrieb der Kontaktflachen zum Stahl Im Gegensatz dazu ist das häufigste Ausfallkriteπum der Breit- seitenplatten eine Rißbildung im GießspiegelbereichIn contrast to the broad side plates, the failure rate of the narrow side plates is not the formation of cracks, but rather the wear or abrasion of the contact surfaces to the steel. In contrast, the most common failure criterion of the wide side plates is crack formation in the area of the mold level
Das Dokument DE 31 20 978 C2 offenbart eine Anzahl ausscheiduπgshartbarer Kupferlegierungen und deren Verwendung für stationäre Stranggießkokillen, u a mit verschiedenen CuNiBe-Legierungen, welche als weitere Legierungsanteile Niob (Nb), Zirkonium (Zr), Magnesium (Mg) und/oder Titan (Ti) enthaltenDocument DE 31 20 978 C2 discloses a number of precipitation-hardenable copper alloys and their use for stationary continuous casting molds, inter alia with various CuNiBe alloys, which, as further alloy components, include niobium (Nb), zirconium (Zr), magnesium (Mg) and / or titanium (Ti ) contain

No. 2,137,281 for a strip mold (twin-belt casting) which is characterized by a combination of properties of comparatively great hardness with comparatively high thermal conductivity

Für einen störungsfreien Gießbetrieb insbesondere von Dunnbrammen mit hohen Gießgeschwindigkeiten, bspw 6 m/min und mehr, reichen die vorhandenen mechanischen Eigenschaften der Kokillenwerkstoffe nicht aus, um die hierbei auftretenden hohen Temperaturen, insbesondere im Bereich des Gießspiegeis, zu beherrschen
Ausgehend vom vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine zur Herstellung von Breitseitenplatten für Dunnbrammen- Stranggießkokillen mit hoher Gießgeschwindigkeit in besonderer Weise geeignete Kupferlegierungen anzugeben, durch deren Verwendung beim Gießbetrieb eine frühzeitige Rißbildung, insbesondere im Bereich des Gießspiegels, vermieden und der Verschleiß der Kontaktflache mit flussigem Stahl reduziert wird, und welche den extrem hohen thermischen und mechanischen Beanspruchungen im Gießbetrieb bei langdauernder Verfügbarkeit widerstehtFor trouble-free casting operations, especially of thin slabs with high casting speeds, e.g. 6 m / min and more, the existing mechanical properties of the mold materials are not sufficient to control the high temperatures that occur, particularly in the area of the casting mirror Starting from the aforementioned prior art, the invention has for its object to provide a suitable for the production of broad side plates for thin slab casting molds with high casting speed in a special way suitable copper alloys, by their use in the casting operation early cracking, especially in the area of the mold level, avoided and Wear of the contact surface with liquid steel is reduced, and which withstands the extremely high thermal and mechanical stresses in the casting operation with long-term availability
Die Losung dieser Aufgabe besteht in der Verwendung einer aushartbaren Kupferlegierung mit einem Gehalt an Beryllium von 0,1 % bis 0,5%, und einem Gehalt an Nickel von 0,5% bis 2,0%, (CuNiBe) zur Herstellung von Breitseitenplatten für Dunnbrammen-StranggießkokillenThe solution to this problem consists in the use of a hardenable copper alloy with a beryllium content of 0.1% to 0.5% and a nickel content of 0.5% to 2.0% (CuNiBe) for the production of broad side plates for thin slab casting molds
Mit großem Vorteil ist diese Kupferlegierung nach ihrer Aushärtung in der Lage, hohe Temperaturspannungen im Gießspiegelbereich unter Vermeidung von Rißbildung aufzunehmen und über längere Betriebszeiten verfugbar zu bleibenAfter hardening, this copper alloy has the great advantage of being able to absorb high temperature stresses in the area of the mold level while avoiding crack formation and to remain available over longer operating times
Zu diesem erfolgreichen Betriebsergebnis - im Gegensatz zu den vorbekannten Kupferlegierungen wie CuCrZr oder CuAg - verhelfen der erfindungsgemaß verwendeten Kupferlegierung CuNiBe ihre vorteilhaften Material-Eigenschaften einer z B wesentlich höheren Zugfestigkeit von ca 770 bzw ca 650 N/mm2 und 0,2 Dehngrenze von ca 500 N/mm2 sowohl bei 20 °C als auch bei 300 °C Die Mate- πaleigenschaften von drei beispielhaft ausgewählten Kupfer-Legierungen, CuCrZr, CuAg sowie CuNiBe sind der folgenden Tabelle zu entnehmen
Material EigenschaftenIn contrast to the previously known copper alloys such as CuCrZr or CuAg, the copper alloy CuNiBe used according to the invention is helped by this advantageous operating result due to its advantageous material properties, for example a much higher tensile strength of approx. 770 or approx. 650 N / mm 2 and 0.2 proof strength of approx 500 N / mm 2 both at 20 ° C and at 300 ° C The material properties of three selected copper alloys, CuCrZr, CuAg and CuNiBe are shown in the following table Material properties
