Abstract
Description
Die Erfindung betrifft ein Aluminiumprodukt aus speziellen Aluminiumlegierungen, welches zu einem Gussbarren, einem Blech oder einem Strangpressteil verarbeitet wird, wobei aus diesen vorgenannten Halbzeugen Bauteile hergestellt werden, die als Zierteile für die Kraftfahrzeuginnen- oder die Kraftfahrzeugaußenausstattung sowie als Zierteile für Haushalts- oder Elektrogeräte Verwendung finden. Derartige Zierteile werden in der Regel einer Glänzbehandlung auf chemischem oder elektrolytischem Wege unterworfen und bei Bedarf eingefärbt. Werden mehrere Zierteile, beispielsweise an einem Kraftfahrzeug vorgesehen, insbesondere bei einer benachbarten Anordnung der Zierteile im Kraftfahrzeug ist es wünschenswert, dass diese Zierteile ein gleiches Aussehen hinsichtlich Glanzgrad und Farbwert aufweisen. Ein Zierteil durchläuft von der Herstellung der entsprechenden Aluminiumlegierung bis zum Einsatz im Kraftfahrzeug einen langen Herstellungsweg. Selbst bei gleichen Herstellungsbedingungen können geringe Einflüsse zu einem merklich unterschiedlichen Aussehen des Zierteils führen. Bei der chemischen und elektrolytischen Behandlung solcher Bauteile, die als Zierteile in ein und dem gleichen Kraftfahrzeug eingesetzt werden sollen, werden diese vorzugsweise in einem Baddurchlauf verarbeitet. Einen weiteren Einfluss auf das Aussehen des Zierteils hat die eingesetzte Aluminiumlegierung. Selbstverständlich werden für die gleichen Zierteile Aluminiumlegierungen gleicher Zusammensetzung verwendet. Derartige Aluminium-Glänzlegierungen werden im Stranggussverfahren hergestellt, wobei ein Aluminiumbasiswerkstoff hoher Reinheit geschmolzen wird und die entsprechenden gewünschten Legierungsbestandteile zulegiert werden. Auch wenn dafür gesorgt wird, dass diese Legierungsbestandteile nur in sehr engen Grenzen variieren dürfen, unterscheiden sich doch die gegossenen Barren, die aus zwei unterschiedlichen Stranggussöfen stammen. Um sicherzustellen, dass Aluminiumprodukte wunschgemäß aus einem Aluminiummaterial gleicher Zusammensetzung, insbesondere aus der gleichen Charge eines Stranggussprozesses hergestellt werden, ist einerseits eine umfassende Dokumentation notwendig und bei Zweifeln eine umfassende Analyse der Zusammensetzung. Wünschenswert wäre eine einfachere Identifikation, die in jeder Phase der Herstellung des Zierteils am jeweiligen Aluminiumprodukt vorgenommen werden kann, d.h. sowohl am Halbzeug (Gussbarren, Blech, Strangpressteil) als auch am mechanisch oder chemisch behandelten Bauteil, wie auch am bereits verwendeten und eingesetzten Zierteil.The invention relates to an aluminum product made of special aluminum alloys, which is processed into a cast ingot, a sheet metal or an extruded part is made from these aforementioned semi-finished parts, as Decorative parts for the motor vehicle interior or the vehicle exterior equipment and used as trim for household or electrical appliances. such Trim pieces are usually a gloss treatment on chemical or subjected to electrolytic routes and dyed if necessary. Become several Decorative parts, for example, provided on a motor vehicle, in particular in a adjacent arrangement of the trim parts in the motor vehicle, it is desirable that These trim parts have the same appearance in terms of gloss and color value exhibit. A garnish goes through the production of the appropriate Aluminum alloy to use in the vehicle a long Production route. Even with the same production conditions can be low Influences lead to a noticeably different appearance of the trim part. In the chemical and electrolytic treatment of such components used as trim in a and the same motor vehicle, they are used preferably processed in a bath pass. Another influence on the The appearance of the trim part has the aluminum alloy used. Of course For the same trim parts, aluminum alloys of the same composition are used used. Such aluminum shining alloys are in the continuous casting process wherein a high purity aluminum base material is melted and alloying the corresponding desired alloying ingredients. Also if it is ensured that these alloying constituents only in very narrow Limits may vary, but the cast bars that are different come from two different continuous casting furnaces. To ensure, that Aluminum products as desired from an aluminum material of the same Composition, in particular from the same batch of a continuous casting process On the one hand, comprehensive documentation is required and included Doubt a comprehensive analysis of the composition. Would be desirable one simpler identification, which at every stage of the manufacture of the trim part on respective aluminum product can be made, i. both on the semi-finished product (Ingot, sheet metal, extruded part) as well as mechanically or chemically treated component, as well as the already used and used trim part.
Neben einer umfassenden spektrometrischen Analyse der Gesamtzusammensetzung der Aluminiumlegierung ist aus der EP 0 861 910 B1 ein Verfahren zum Erkennen unterschiedlicher Aluminiumlegierungen bekannt. Bei diesem Verfahren werden die Legierungen chemische behandelt und auf Grund der unterschiedlichen Färbung getrennt. Ein solches Identifikationverfahren ist nur sehr grob und kann nur bei Aluminiumlegierungen mit sehr unterschiedlichen Legierungsbestandteilen eingesetzt werden.In addition to a comprehensive spectrometric analysis of the overall composition The aluminum alloy is known from EP 0 861 910 B1 a method for detecting different aluminum alloys known. In this process, the Alloys treated chemically and due to the different coloration separated. Such an identification procedure is only very rough and can only be used with Aluminum alloys with very different alloy components be used.
Aus den Dokumenten DE 199 38 995 A 1 und EP 1 029 937 A 1 sind Aluminium-Magnesium-Silicium-Legierungen für Aluminiumbleche bekannt. Diese Aluminiumlegierungen können u.a. einen Gewichtsanteil Silber enthalten. Dieser Silberanteil soll einen wirkungsvollen Beitrag zur Aushärtung liefern und wird daher in Größenordnungen von 0,1 bzw. 0,2 Gew% gewählt, wenn ausschließlich Silber als Zusatz für die Warmaushärtung zugesetzt wird. Bei Aluminiumglänzlegierungen werden die Anteile an Fremdmetall jedoch möglichst niedrig gehalten, ausschließlich Gewichtsanteile an Magnesium und Silicium für eine ausreichende Festigkeit werden einer solchen Glänzlegierung zulegiert. Weitere Legierungsgehalte werden möglichst gering gehalten, um den Glänzeffekt nicht unnötig zu reduzieren. Documents DE 199 38 995 A1 and EP 1 029 937 A1 disclose aluminum-magnesium-silicon alloys known for aluminum sheets. These Aluminum alloys may u.a. contain one part by weight of silver. This Silver content should provide an effective contribution to the curing and therefore in the order of 0.1 or 0.2% by weight selected, if only silver as Addition for the hot curing is added. For aluminum alloy alloys however, the levels of foreign metal are kept as low as possible, exclusively by weight of magnesium and silicon for a sufficient Strength are added to such a glaze alloy. Further alloy contents are kept as low as possible in order not to reduce the glare effect unnecessarily.
Ein merklicher Anteil an Silber, der die mechanischen Eigenschaften des Glänzwerkstoffes beeinflussen würde, ist daher unerwünscht.A significant proportion of silver, which reflects the mechanical properties of the Brightening material would affect, is therefore undesirable.
Aufgabe der Erfindung ist es, eine einfache und preiswerte Möglichkeit zur Identifikation von Aluminiumprodukten aus Aluminiumglänzlegierungen zur Verfügung zu stellen.The object of the invention is to provide a simple and inexpensive way to Identification of aluminum products from aluminum alloy alloys To make available.
Die Aufgabe dieser Erfindung wird mit einem Aluminiumprodukt der Zusammensetzung gemäß Anspruch 1 gelöst. Durch den Zusatz von geringen Spuren an Silber, die jedoch noch nachweisbar sein müssen, lässt sich eine entsprechende Aluminiumlegierung identifizieren. Die derzeitige Nachweisgrenze bei modernen Spektrometern liegt bei 0,00005 Gew% Silber. Um ein sicheres Ergebnis zu liefern, sollte der Zusatz an Silber höher liegen. Als untere Grenze hat sich ein Anteil von 0,0005 Gew% als noch praktikabel erwiesen. Als Obergrenze für den Zusatz an Silber zur Identifikation werden 0.005 Gew% angegeben. Ein höherer Zusatz an Silber ist aus zwei Gründen nicht sinnvoll. Zum einen steigen die Kosten der entstehenden Aluminiumlegierung unnötig und des weiteren hat ein höherer Anteil an Silber Einfluss auf die Eigenschaften der Aluminiumlegierung.The object of this invention is with an aluminum product of Composition according to claim 1 solved. By the addition of small traces of silver, which still have to be detectable, can be a corresponding Identify aluminum alloy. The current detection limit in modern Spectrometers is 0.00005 wt% silver. To deliver a sure result, the addition of silver should be higher. The lower limit is a share of 0.0005 wt% proved to be still practicable. As upper limit for the addition to Silver for identification is given as 0.005 wt%. A higher addition to Silver does not make sense for two reasons. For one thing, the costs of the resulting aluminum alloy unnecessary and further has a higher proportion on silver influence on the properties of the aluminum alloy.
Zur Herstellung eines solchen Aluminiumwerkstoffes wird ein
Aluminiumbasiswerkstoff mit mehr als 99,8 Gew% Aluminium in einem
Schmelzofen bei ca. 660- 750 °C geschmolzen. Vorzugsweise werden
Aluminiumbasiswerkstoffe mit mehr als 99,85 Gew% bzw. 99,9 Gew% eingesetzt.
Der Schmelze werden die gewünschten Legierungsbestandteile in dem Schmelzofen
oder nach Überführung in einem Gußofen zulegiert. Dies sind:
Die entstehenden Gussbarren können des Weiteren folgende Bestandteile aufweisen, nämlich maximal 0.03 Gew% Mangan, maximal 0,05 Gew% Zink und maximal 0,02 Gew% Titan. Diese Bestandteile können bereits im Aluminiumbasiswerkstoff enthalten sein oder Bestandteil einer Vorlegierung sein.The resulting ingots may further include the following components namely a maximum of 0.03% by weight of manganese, a maximum of 0.05% by weight of zinc and a maximum of 0.02 % Titanium by weight. These components can already be found in the aluminum base material be contained or be part of a master alloy.
Es ist nicht zu erwarten, dass beim Einsatz von Schrottrücklaufen beispielsweise für den Aluminiumbasiswerkstoff bereits ein merklicher nachweisbarer Anteil an Silber in die Ausgangsschmelze gelangt. Im Schmelzofen wird nur soviel Aluminiumschrott eingesetzt, dass sichergestellt ist, dass ein Basiswerkstoff mit mindestens 99,8 Gew% Aluminium enthalten ist. Dies wird durch mehrere Probennahmen und Analysen kontrolliert. Eine als Aluminiumschrott deklarierte Aluminium-Glänzlegierung kann zwar für die Herstellung einer neuen Glänzlegierung herangezogen werden, wird im Schmelzofen jedoch mit soviel Frischmetall versetzt, dass die im Aluminiumschrott vorhandenen Legierungselemente einzeln weniger als 0,01 Gew% und insgesamt weniger als 0,15 Gew% ausmachen. In diesen Fällen sind geringe Silberanteile aus den Schrotten nicht mehr nachweisbar. Querverunreinigungen aus Schrottrücklaufen sind also ausgeschlossenIt is not to be expected that when using scrap recycling, for example the aluminum base material already a noticeable detectable proportion of silver gets into the starting melt. In the melting furnace, only so much aluminum scrap is used that it is ensured that a base material contains at least 99.8% by weight Aluminum is included. This is done through multiple sampling and analysis controlled. An aluminum shining alloy declared as aluminum scrap can Although used for the production of a new shining alloy, is Melting furnace, however, mixed with so much virgin metal that in the aluminum scrap individually present less than 0.01 wt% and total alloying elements less than 0.15% by weight. In these cases, small amounts of silver are excluded no longer detectable in the scraps. Cross contamination from scrap recycling are excluded
Von den hergestellten Gussbarren einer Charge wird je eine Probe spektrometisch analysiert, um die Gesamtzusammensetzung zu erhalten und den Silberanteil festzustellen. Dieser Silberanteil lässt sich in den nachfolgenden Verarbeitungsschritten jederzeit nachweisen, d.h. am umgeformten Produkt, was beispielsweise ein Strangpressteil oder ein warmgewalztes und/oder kaltgewalztes Blech sein kann. Einer solchen Umformung folgt neben der mechanischen Bearbeitung insbesondere eine chemische und elektrolytische Behandlung des Bauteils zu einer Zierleiste, Zierblende oder einem geformten Zierteil. Eine solche chemische und elekrolytische Behandlung schließt ein Polieren, Glänzen, Eloxieren, evtl. ein Einfärben und ein abschließendes Verdichten der Bauteile ein. Bei jedem der vorgenannten Verfahrensschritte ist es möglich, das Bauteil einer bestimmten Ausgangscharge des Stranggusses zuzuordnen. In gleicher Weise ist dies zu einem wesentlich späteren Zeitpunkt, beispielsweise bei einer Reklamation des Kunden, möglich.Of the produced ingots of a batch, one sample is spectrometrically analyzed to obtain the total composition and the silver content determine. This proportion of silver can be in the following Processing steps at any time, i. on the formed product, what For example, an extrusion or a hot-rolled and / or cold-rolled Can be sheet metal. Such reshaping follows next to the mechanical one Processing in particular a chemical and electrolytic treatment of Component to a trim strip, trim or a shaped trim part. Such chemical and electrolytic treatment includes polishing, glazing, anodizing, possibly a coloring and a final compaction of the components. At each the above method steps, it is possible to the component of a certain Assign initial batch of continuous casting. In the same way this is to one much later, for example in the case of a customer complaint, possible.
Untersuchungen solcher Aluminiumprodukte aus Aluminiumglänzlegierungen mit einem geringen Silberanteil haben keinen negativen Einfluss auf die mechanischen und chemischen Eigenschaften. Bei der Untersuchung der Korrosionsbeständigkeit im Abtragstest und Salzsprühtest ergaben sich gleich gute Werte. Auch die Glanzwerte nach dem Polieren, elektrolytischen oder chemischen Glänzen oder nach dem Eloxieren waren gleich gut oder geringfügig besser. Bei der Untersuchung der Farbbeständigkeit ergab sich eine leichte Verschiebung der Farbwerte (im Lab-System gemessen: im b-Wert um 0,5 kleiner). Damit erscheinen die Bauteile mit einem geringfügigen Silberzusatz kälter bzw. glänzender.Investigations of such aluminum products from aluminum alloys with a small amount of silver has no negative impact on the mechanical properties and chemical properties. In the study of corrosion resistance In the erosion test and salt spray test, the same good results were obtained. Also the Gloss values after polishing, electrolytic or chemical glazing or after Anodizing was equally good or slightly better. In the investigation of Color stability resulted in a slight shift in color values (in the Lab system measured: smaller by 0.5 in the b-value). Thus, the components appear with a minor addition of silver colder or shinier.
Im Nachfolgenden wird ein Ausführungsbeispiel wiedergegeben. Als
Aluminiumbasiswerkstoff wurde Reinaluminium mit mindestens 99,85 Gew%
Aluminium eingesetzt. Der Aluminiumschmelze wurden Magnesium, Silicium,
Kupfer und Silber als Reinmetall zugesetzt. Des Weiteren wurde in den
Stranggussofen Titanborid in Form einer AlTi 5% B 1%-Vorlegierung der Schmelze
als Kornfeinerungsmittel zugesetzt. Die entstehenden Gussbarren hatten folgende
Zusammensetzung:
Die Legierungselemente Silicium, Eisen, Kupfer und Magnesium liegen im gewünschten Konzentrationsbereich. Aufgrund des Zulegierens in Form reiner Metalle konnte Mangan und Zink nicht nachgewiesen werden. Der Gehalt an Titan, bewirkt durch den Zusatz des Kornfeinerungsmittels, hält sich ebenfalls in den gewünschten Grenzen. Sonstige Verunreinigungen, nämlich Bor, Natrium, Kalzium, Nickel und Vanadium übersteigen einzeln nicht einen Gehalt von 0,02 Gew% und insgesamt ist der Anteil an Verunreinigungen kleiner als 0,15 Gew%.The alloying elements silicon, iron, copper and magnesium are in the desired concentration range. Due to the Zulegierens in the form of pure Metals could not be detected manganese and zinc. The content of titanium, caused by the addition of the grain refining agent, also holds in the desired limits. Other impurities, namely boron, sodium, calcium, Nickel and vanadium individually do not exceed a content of 0.02% by weight and in total, the content of impurities is less than 0.15% by weight.
Bei einem weiteren Stranggussversuch, ausgehend von der Schmelze des gleichen
Aluminiumbasiswerkstoffes, nämlich Aluminium 99,85 werden in einem weiteren
Stranggussofen wieder mittels Reinmetall die Legierungsbestandteile zulegiert sowie
Silber zugesetzt. Die entstehenden Gussbarren zeigten die folgende
Zusammensetzung:
Die Glänzlegierungen der Gussbarren unterschiedlicher Stranggussversuche unterscheiden sich etwas im Eisengehalt. Um die Gussbarren dieser zwei verschiedenen Gussverfahren auseinander zu halten, ist eine Identifikation allein über den Silbergehalt möglich, der bei dem zweiten Gussverfahren etwas erhöht wurde. Die Identifizierung von Aluminiumprodukten aus unterschiedlichen Gussbarren ist nachfolgend jederzeit möglich.The shining alloys of cast ingots of different continuous casting experiments differ slightly in iron content. Around the cast bars of these two differentiating between different casting methods is an identification alone possible over the silver content, which increases slightly in the second casting process has been. The identification of aluminum products from different Cast ingot is possible at any time.
