Description

Die Erfindung betrifft Bänder und Tafeln aus legiertem Zink auf der Basis von wenigstens 99,99% Zink mit Zusätzen von 0,05 bis 0,2 Gew.% Titan, 0,02 bis 0,2 Gew.% Kupfer und 0,005 bis 0,05 Gew.% Aluminium vorzugsweise für das Bauwesen.The invention relates to strips and bars made of alloyed zinc based on at least 99.99% zinc with additions of 0.05 to 0.2% by weight of titanium, 0.02 to 0.2% by weight of copper and 0.005 to 0, 05% by weight aluminum, preferably for the building industry.

Dieser in der DE-C-1 758 489 beschriebene und nach DIN 17 770 Teil 1 genormte Werkstoff wird seit vielen Jahren insbesondere im Bauwesen wegen seiner vorzüglichen Werkstoffeigenschaften eingesetzt. Die aus diesem Werkstoff hergestellten Bänder und Bleche sind unabhängig von der Walzrichtung anrißfrei um 180° faltbar, bleiben bruchfrei beim Wiederaufbiegen und zeichnen sich durch eine hohe Duktilität bei jeder Art Umformung, auch bei Kaltverformung aus. Die Mindestanforderungen an die mechanisch technologischen Eigenschaften der aus diesem Werkstoff hergestellten Bänder und Bleche sind in DIN 17 770 aufgeführt. In DIN 17 770 Teil 2 sind die Maße für solche Bänder und Bleche angegeben.This material described in DE-C-1 758 489 and standardized in accordance with DIN 17 770 Part 1 has been used for many years in particular in the construction industry because of its excellent material properties. The strips and sheets made from this material can be folded by 180 ° regardless of the rolling direction, remain unbreakable when re-bent and are characterized by high ductility in every type of forming, even with cold forming. The minimum requirements for the mechanical-technological properties of the strips and sheets made from this material are listed in DIN 17 770. The dimensions for such strips and sheets are specified in DIN 17 770 Part 2.

Die Herstellung des Werkstoffs erfolgt im allgemeinen unter Anwendung des Gieß-Walz-Verfahrens bei dem in einem ununterbrochenen Verfahrensgang (Schmelzen- Gießen-Walzen Aufwickeln) Bänder in vorgegebenen Dicken hergestellt werden, die anschließend auf Scherenlinien zu Schmalbändern oder Tafeln geschnitten werden. Der Werkstoff ist in der Atmosphäre gut beständig. Die Oberfläche reagiert zunächst unter Bildung von Zinkoxid mit dem Sauerstoff der Luft. Durch Einwirkung von Wasser bildet dann Zinkhydroxid das durch Reaktion mit dem Kohlendioxid der Luft zu einer dichten, festhaftenden und wasserunlöslichen Deckschicht aus basischen Zinkcarbonat umgewandelt wird. Diese Schutzschicht ist verantwortlich für den hohen Korrosionswiderstand.The production of the material is generally carried out using the casting-rolling process in which strips are produced in predetermined thicknesses in an uninterrupted process step (melting-casting-rolling-winding), which are then cut into narrow strips or sheets on scissor lines. The material is stable in the atmosphere. The surface initially reacts with the oxygen in the air to form zinc oxide. Through the action of water, zinc hydroxide then forms which, when reacted with the carbon dioxide in the air, is converted into a dense, firmly adhering and water-insoluble cover layer made of basic zinc carbonate. This protective layer is responsible for the high corrosion resistance.

Es ist die Aufgabe der vorliegenden Erfindung, die mechanischen Eigenschaften, insbesondere die Zugfestigkeit, der eingangs angeführten Zinklegierung deutlich zu verbessern, ohne jedoch deren gute Duktivität zu beeinträchtigen.It is the object of the present invention to significantly improve the mechanical properties, in particular the tensile strength, of the zinc alloy mentioned at the outset, without, however, impairing its good ductility.

Zur Lösung dieser Aufgabe enthält die Zinklegierung als weiteren Zusatz 0,005 bis 0,04 Gew.% Magnesium oder 0,001 bis 0,1 Gew.% Lithium.To achieve this object, the zinc alloy contains 0.005 to 0.04% by weight of magnesium or 0.001 to 0.1% by weight of lithium as a further additive.

Im Rahmen der weiteren Ausgestaltung der Erfindung enthält die Legierung 0,005 bis 0,0075 Magnesium und 0,01 bis 0,5 Gew.% Lithium.In the context of the further embodiment of the invention, the alloy contains 0.005 to 0.0075 magnesium and 0.01 to 0.5% by weight of lithium.

Bei dem Verfahren zur Herstellung der Bänder und Bleche aus legiertem Feinzink mit einem Reinheitsgrad von wenigstens 99,99% Zink mit Zusätzen von 0,005 bis 0,02 Gew.% Titan 0,02 bis 0,2 Gew.%, 0,005 bis 0,5 Gew.% Aluminium und 0,005 bis 0,04 Gew.% Magnesium oder 0,01 bis 0,1 Gew.% Lithium wird die Legierung mit einer Schmelztemperatur von ≧ 420° zwischen umlaufenden Metallbändern kontinuierlich zu einem Band gegossen und unmittelbar anschließend in mehreren Stufen auf die vorgegebene Dicke abgewalzt, wobei erfindungsgemäß das Band in der letzten Walzstufe bei einer Temperatur vorzugsweise von 100 bis 250°C, vorzugsweise 100 bis 170°C gewalzt wird.In the process for producing the strips and sheets from alloyed fine zinc with a purity of at least 99.99% zinc with additions of 0.005 to 0.02% by weight of titanium 0.02 to 0.2% by weight, 0.005 to 0.5 % By weight of aluminum and 0.005 to 0.04% by weight of magnesium or 0.01 to 0.1% by weight of lithium, the alloy is continuously cast into a strip with a melting temperature of ≧ 420 ° between surrounding metal strips and immediately afterwards in several stages rolled to the specified thickness, the strip being rolled according to the invention in the last rolling stage at a temperature preferably from 100 to 250 ° C., preferably 100 to 170 ° C.

Es ist auch möglich, das Band in der letzten Walzstufe bei einer Temperatur unterhalb der Rekristallisationstemperatur zu walzen, vorzugsweise kaltzuwalzen und 0,75 bis 2,5 Stunden bei einer Temperatur von 150 bis 300°C zu erwärmen.It is also possible to roll the strip in the last rolling stage at a temperature below the recrystallization temperature, preferably cold-rolling and heating it at a temperature of 150 to 300 ° C. for 0.75 to 2.5 hours.

Aus der zum Stand der Technik gehörenden Feinzinklegierung (I) der Zusammensetzung 0,09 Gew.% Titan, 0,13 Gew.% Kupfer und 0,007 Gew.% Aluminium Rest Feinzink von 99,995% Zink und der erfindungsgemäßen Feinzinklegierung (II) mit der Zusammensetzung 0,10 Gew.% Titan 0,15 Gew.% Kupfer, 0,007 Gew.% Aluminium und 0,1 Gew.% Magnesium wurden Bänder gegossen und auf das Endmaß von 0,8 mm fertiggewalzt und anschließend die mechanischen Eigenschaften dieser Bänder nach DIN 17 770 Teil 1 zu Vergleichszwecken gemessen.From the state of the art fine zinc alloy (I) with the composition 0.09% by weight Titanium, 0.13% by weight copper and 0.007% by weight aluminum remainder fine zinc of 99.995% zinc and the fine zinc alloy (II) according to the invention with the composition 0.10% by weight titanium 0.15% by weight copper, 0.007% by weight Aluminum and 0.1% by weight of magnesium were cast into strips and finish-rolled to a final dimension of 0.8 mm and then the mechanical properties of these strips were measured in accordance with DIN 17 770 Part 1 for comparison purposes.

Folgende mechanische Eigenschaften wurden ermittelt:

  • 1. Härteprüfung
    Die Prüfung der Vickershärte (HV 1) erfolgte gemäß DIN 50 133, Teil 2. Fig. 1 zeigt das Ergebnis nach einer Auslagerung der Versuchswerkstoffe bei 60 °C und einer Auslagerungsdauer von bis zu 100 Stunden. Das aus der erfindungsgemäßen Feinzinklegierung (II) hergestellte Band besitzt bei Raumtemperatur eine um etwa 100% größere Vickershärte verglichen mit derjenigen des Bandes als der zu Stand der Technik gehörenden Feinzinklegierung (I). Eine Auslagerung bei 60°C verändert diese Relation nicht.
  • 2. 1%-Dehngrenze (N/mm2)
    Gemäß Fig. 2 und Fig. 3 ist die erfindungsgemäße Feinzinklegierung (II) hinsichtlich 1%-Dehngrenze der entsprechenden mechanischen Eigenschaften der bekannten Feinzinklegierung (I) um etwa 100%, längs und quer zur Walzrichtung gemessen, überlegen. Dies gilt auch bei relativ hohen Temperaturen von bis zu 100°C.
  • 3. Wie Fig. 4 und 5 zu entnehmen ist, ist die erfindungsgemäße Feinzinklegierung (II) hinsichtlich der Zugfestigkeit (N/mm2) um etwa 100% der bekannten Feinzinklegierung (I) überlegen.
  • 4. Bruchdehnung A5(%)
    Gemäß Fig. 6 und 7 bewegt sich die Bruchdehnung für die erfindungsgemäße wie für die bekannte Feinzinklegierung in einem für technische Belange zufriedenstellenden Bereich sowohl längs als auch quer zur Walzrichtung.
  • 5. Zeitstandfestigkeit Rm/100 (N/mm2)
    Die Zeitstandversuche erfolgten gemäß DIN 50 118 bei Raumtemperatur 60°C und 100°C. Wie Fig. 8 und 9 zeigen, ist längs und quer zur Walzrichtung die Festigkeit der erfindungsgemäßen Feinzinklegierung (II) im Durchschnitt 50% bis 80% höher als die der bekannten Feinzinklegierung (I).
  • 6. Faltversuche
    Es wurden Proben von 60 x 20 mm längs und quer zu Walzenrichtung ohne Zwischenlage um 180 Grad gefaltet. Die Prüftemperaturen betrugen 22°C, 0°C und -10°C. Die Proben waren unabhängig von der Walzrichtung anrißfrei um 180 Grad faltbar und bruchfrei beim Wiederaufbiegen.
  • 7. Dauerschwingversuche
    Die mit Blechproben gemäß DIN 50 100 erfolgten Dauerschwingversuche längs zur Walzrichtung mit einer Prüffrequenz von 30 Hz bei einer Temperatur von 22°C führten zu Dauerfestigkeitswerten von 68 N/mm2 für die erfindungsgemäße Feinzinklegierung (II) und zu 55 N/mm2 für die bekannte Feinzinklegierung (I).
  • 8. Bruchfestigkeit (N/mm2)
    Die Bruchfestigkeit wurde längs und quer zur Walzrichtung als Funktion der Temperatur geprüft. Wie aus Fig. 10 und 11 entnommen werden kann, ist die erfindungsgemäße Feinzinklegierung (II) derjenigen mit der bekannten (I) Zusammensetzung deutlich überlegen. Werden die Proben beidseitig mit einer Kerbe der Spannungskonzentration αK=2.6 versehen, liegt die Bruchfestigkeit über der der glatten Proben. Verantwortlich hierfür ist die ungleichmäßige Spannungsverteilung im Prüfquerschnitt und der damit verbundene räumliche Spannungszustand. Daraus ist abzuleiten, daß im Sinne einer Randkerbe geschädigte Bauteile unter statischer Belastung nicht versagen werden.
The following mechanical properties were determined:
  • 1. Hardness test
    The Vickers hardness (HV 1) was tested in accordance with DIN 50 133, part 2. FIG. 1 shows the result after aging of the test materials at 60 ° C. and an aging period of up to 100 hours. The strip produced from the fine zinc alloy (II) according to the invention has a Vickers hardness which is about 100% greater at room temperature compared to that of the strip than the fine zinc alloy (I) belonging to the prior art. An aging at 60 ° C does not change this relation.
  • 2.1% yield strength (N / mm 2 )
    According to FIGS. 2 and 3, the fine zinc alloy (II) according to the invention is superior to the known mechanical properties of the known fine zinc alloy (I) by about 100% with respect to the 1% proof stress, measured lengthways and crosswise to the rolling direction. This also applies at relatively high temperatures of up to 100 ° C.
  • 3. As can be seen from FIGS. 4 and 5, the fine zinc alloy (II) according to the invention is superior in tensile strength (N / mm 2 ) by about 100% of the known fine zinc alloy (I).
  • 4. Elongation at break A5 (%)
    According to FIGS. 6 and 7, the elongation at break for the fine zinc alloy according to the invention and for the known fine zinc alloy moves in a region which is satisfactory for technical reasons, both longitudinally and transversely to the rolling direction.
  • 5. Creep rupture strength Rm / 100 (N / mm 2 )
    The creep tests were carried out in accordance with DIN 50 118 at room temperature 60 ° C and 100 ° C. As shown in FIGS. 8 and 9, the strength of the fine zinc alloy (II) along and across the rolling direction is on average 50% to 80% higher than that of the known fine zinc alloy (I).
  • 6. Folding attempts
    Samples of 60 x 20 mm were folded longitudinally and transversely to the direction of the roll without an intermediate layer by 180 degrees. The test temperatures were 22 ° C, 0 ° C and -10 ° C. Regardless of the direction of rolling, the samples were foldable by 180 degrees and unbreakable when re-bent.
  • 7. Fatigue tests
    The fatigue tests carried out with sheet metal samples in accordance with DIN 50 100 along the rolling direction with a test frequency of 30 Hz at a temperature of 22 ° C led to fatigue strength values of 68 N / mm 2 for the fine zinc alloy (II) according to the invention and 55 N / mm 2 for the known fine zinc alloy (I).
  • 8. Breaking strength (N / mm 2 )
    The breaking strength was tested along and across the rolling direction as a function of temperature. As can be seen from FIGS. 10 and 11, the fine zinc alloy (II) according to the invention is that with the known (I) composition clearly superior. If the samples are provided on both sides with a notch of the stress concentration α K = 2.6, the breaking strength is higher than that of the smooth samples. This is due to the uneven stress distribution in the test cross-section and the associated spatial stress state. From this it can be deduced that components damaged in the sense of an edge notch will not fail under static load.

Die vorliegenden Untersuchungsergebnisse belegen, daß die mechanischen Eigenschaften der bekannten Feinzinklegierung durch das Zulegieren von 0,0005 bis 0,04 Gew.% Magnesium ganz erheblich verbessert werden können und damit ein breiterer Anwendungsbereich der Feinlegierung erreicht wird.The present test results prove that the mechanical properties of the known fine zinc alloy can be considerably improved by alloying 0.0005 to 0.04% by weight of magnesium, and thus a broader application range of the fine alloy is achieved.
