Description
Gegenstand der Erfindung ist ein Verfahren zur Herstellung von Bleigußband als Vorprodukt für Streckmetallgitter in Bleiakkumulatoren durch Gießen eines Bleistreifens auf die gekühlte Oberfläche einer rotierenden Walze.The invention relates to a process for the production of lead cast strip as a preliminary product for expanded metal grids in lead accumulators by pouring a lead strip onto the cooled one Surface of a rotating roller.
Elektrodengitter für Bleiakkumulatoren werden nach den verschiedensten Verfahren hergestellt. Beispielsweise werden auf Gittergießmaschinen mehrere Gitter auf einmal in feststehende Formen gegossen, oder es wird gemäß der DE-A 30 28 957 ein kontinuierliches Gitterband mittels einer in flüssiges Blei eintauchenden, rotierenden Trommel, die das Gittermuster eingeprägt besitzt, hergestellt.Electrode grids for lead-acid batteries are manufactured using a wide variety of processes. For example, on grid casting machines, several grids are fixed at once Molds are cast, or according to DE-A 30 28 957, there is a continuous grid belt by means of a rotating drum immersed in liquid lead, which forms the grid pattern has embossed, manufactured.
In anderen Verfahren werden die Elektrodengitter mit einer Streckmetalltechnik aus einem Bleiband hergestellt. Das dazu erforderliche Bleiband kann beispielsweise gemäß US-A 5462109 durch Gießen eines Bleistreifens auf die gekühlte Oberfläche einer Trommel hergestellt werden.In other processes, the electrode grids are made from an expanded metal technique Lead tape made. The lead tape required for this can, for example, according to US-A 5462109 made by pouring a pencil onto the cooled surface of a drum become.
Sowohl Bleiband, welches durch Walzen, als auch Bleiband, das durch kontinuierliches
Bandgießen hergestellt wird, besitzt allerdings nachteilige Eigenschaften. In beiden Fällen ist
das so hergestellte Bandmaterial anisotrop. Bei Walzband ist eine charakteristische Walztextur
vorhanden, die zu einer maximalen Zugfestigkeit in Walzrichtung und geringerer
Festigkeit senkrecht zur Walzrichtung führt. Bei Gußband, das, wie oben erwähnt, durch
kontinuierlichen Guß gegen eine rotierende innen gekühlte Trommel erzeugt wird, ist eine
gerichtete Erstarrung mit einer charakteristischen Ausrichtung der Korngrenzen in der
Bandrichtung mit einem Neigungswinkel gegen die Bandoberfläche vorhanden, die durch
Bandvorschub und die Kühlwirkung der Trommel bestimmt ist. In der Querrichtung fehlt
diese bevorzugte Ausrichtung der Korngrenzen völlig. Auch Gußband ist in diesen Sinn
anisotrop. Bei der Herstellung von Streckmetall aus Gußband kann die stengelige Kornstruktur
mit gegen die Bandoberfläche die geneigten Korngrenzen zu einer unerwünschten
Konzentration der Verformung an den Korngrenzen und zur starken Verschiebung der Körner
entlang der Korngrenzen führen (R.D. Prengaman 
Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Herstellung eines Gußbandes und eine dazu geeignete Vorrichtung anzugeben, mit denen die Nachteile der bekannten Verfahren vermieden werden und die Korrosionsbeständigkeit und mechanische Festigkeit der aus dem Band hergestellten Gitter im Bleiakkumulator verbessert werden.The invention has for its object a method for producing a cast strip and to provide a suitable device with which the disadvantages of the known Procedures are avoided and the corrosion resistance and mechanical strength the grid made from the strip can be improved in the lead accumulator.
Diese Aufgabe wird bei einem Verfahren gemäß dem Oberbegriff des Anspruchs 1 durch die
im kennzeichnenden Teil des Anspruchs angegebenen Maßnahmen gelöst. In den Unteransprüchen
sind vorteilhafte Ausgestaltungen des Verfahrens und eine zur Durchführung des
Verfahrens geeignete Vorrichtung angegeben.This object is achieved in a method according to the preamble of
Wie bereits eingangs erwähnt, hat ein durch kontinuierlichen Guß gegen eine rotierende innen gekühlte Trommel hergestelltes Gußband eine charakteristische Struktur mit einer Ausrichtung der Korngrenzen in Bandgußrichtung unter einem Neigungswinkel gegen die Bandoberfläche, der durch die Bandvorschubgeschwindigkeit und die Kühlwirkung der Trommel bestimmt wird. In der dazu senkrechten Querrichtung des Bandes fehlt diese Ausrichtung. Diese Struktur ist in Figur 1 schematisch dargestellt, dabei ist mit B die Bandgußrichtung und mit Q der Wärmeabfluß aus dem gegossenen Band bezeichnet.As already mentioned at the beginning, one has a continuous casting against a rotating inside Cooled drum-made cast tape has a characteristic structure with an orientation the grain boundaries in the strip casting direction at an angle of inclination against the Belt surface, which is determined by the belt feed speed and the cooling effect of the Drum is determined. This orientation is missing in the perpendicular transverse direction of the belt. This structure is shown schematically in FIG. 1, with B being the strip casting direction and Q denotes the heat flow from the cast strip.
Sowohl für den Streckprozeß als auch für die Verformungseigenschaften des Gitters unter der Wirkung der Zugspannungen, die durch Aufwachsen von Oxidschichten erzeugt werden (Gitterwachstum), ist eine möglichst homogene und isotrope Verteilung der Festigkeit in der Bandebene und somit auch der Gitterebene vorteilhaft. Dies wird beim traditionellen Guß von Bleigittern in feststehenden Formen erreicht, da die Abkühlung senkrecht zur Gitterebene erfolgt und damit die Lage der Korngrenzen im wesentlichen senkrecht zur Gitterebene und senkrecht sowohl zu den Oberflächen als auch zur Verlaufsrichtung der Gitterstege unabhängig von der Ausrichtung der Stege in der Gitterebene erfolgt.Both for the stretching process and for the deformation properties of the grid below the effect of tensile stresses generated by the growth of oxide layers (Lattice growth) is a homogeneous and isotropic distribution of the strength in the Band level and thus also the grid level advantageous. This is the traditional casting of Lead grids in fixed forms are achieved because the cooling is perpendicular to the grating plane takes place and thus the position of the grain boundaries substantially perpendicular to the lattice plane and perpendicular to both the surfaces and the direction of the crosspieces from the alignment of the webs in the lattice plane.
Bei kontinuierlich gegossenem Band können Korngrenzen, je nach den Wärmeflußverhältnissen im Moment der Erstarrung, d.h. also, abhängig vom Bandvorschub, von der Kühlrate und von der Richtung des Wärmeabflusses beispielsweise um 70° gegen die Bandoberfläche geneigt sein und es können sich somit Schubspannungskomponenten bei Belastung in Richtung der Stegachse ergeben.With continuously cast strip, grain boundaries can exist, depending on the heat flow conditions at the moment of solidification, i.e. depending on the belt feed, the cooling rate and the direction of heat flow, for example, 70 ° against the strip surface be inclined and it can thus shear stress components under load in Direction of the web axis.
Bei Aushärtungszuständen, bei denen das Korninnere eine höhere Festigkeit hat als die Korngrenze, kann die Korngrenze grundsätzlich zum Schwachpunkt der gesamten Struktur werden. Es kann sogenanntes Korngrenzgleiten erfolgen. Dies gilt allerdings nur für Belastungen, die parallel zur ursprünglichen Bandvorschubrichtung liegen. Senkrecht dazu entspricht die Lage der Korngrenzen der bei Gußgittern. Die Festigkeit des Einzelsteges eines daraus hergestellten Gitters hängt damit in unerwünschter Weise von seinem Drehwinkel zur ursprünglichen Bandrichtung ab.For curing conditions in which the interior of the grain has a higher strength than that Grain boundary, the grain boundary can basically become the weak point of the entire structure become. So-called grain boundary sliding can take place. However, this only applies to loads, which are parallel to the original tape feed direction. Perpendicular to it the location of the grain boundaries of the cast grids. The strength of the single web grating made from it thus undesirably depends on its angle of rotation original tape direction.
Dieser grundsätzliche Nachteil wird durch die erfindungsgemäß unmittelbar auf die Erstarrung folgende Verformung weitestgehend beseitigt, die durch Rekristallisation zu einer isotropen Festigkeitsverteilung führt. Diese zusätzliche Verformung besteht in einer Dickenreduktion um ca. 1% bis 25%, insbesondere ca. 15% - 25%. Diese Dickenreduktion kann in mehreren Schritten erfolgen, sie sollte jedoch stets so dicht am Erstarrungspunkt des Bandes erfolgen, daß die Bandtemperatur bei der ersten Verformung zwischen 100 und 300°C liegt.This fundamental disadvantage is due to the solidification according to the invention following deformation largely eliminated, which by recrystallization to a leads to isotropic distribution of strength. This additional deformation consists in a reduction in thickness by approx. 1% to 25%, in particular approx. 15% - 25%. This reduction in thickness can be in several steps, but it should always be as close to the solidification point of the belt take place that the strip temperature during the first deformation between 100 and 300 ° C. lies.
In Figur 2 ist schematisch eine Vorrichtung zur Durchführung des erfindungsgemäßen Verfahrens
dargestellt. Diese besitzt in an sich bekannter Weise einen Vorratsbehälter mit flüssigem
Blei 1, aus dem ein Streifen 2 aus Blei auf die innen gekühlte, rotierende Trommel 3
gegossen wird.FIG. 2 schematically shows an apparatus for performing the method according to the invention
shown. In a manner known per se, this has a storage container with
Erfindungsgemäß ist der Vorrichtung zur Herstellung des Gußbandes eine Anordnung mit
einem oder mehreren Walzenpaaren 4 direkt nachgeschaltet, die so dicht hinter der Erstarrungszone
des aus der Gießanlage auslaufenden Bandes angeordnet sind, daß unter
Nutzung der Eigenwärme und bei möglichst geringer zusätzlicher Erwärmung des Bandes
eine Dickenreduktion um 1% bis 25%, insbesondere um 15% - 25%, erfolgt, die die gewünschte
Rekristallisation, die zu einer isotropen Festigkeitsverteilung führt, auslöst.According to the invention, the device for producing the cast strip is provided with an arrangement
one or more pairs of
Vorteilhaft ist es, daß der erste Walzvorgang bei einem mehrstufigen Walzvorgang im Bereich des Erstarrungsintervalls der Legierung liegt und dabei zusätzlich eine gleichmäßige Abkühlung der letzten, noch nicht erstarrten Bereiche des Bandes erfolgt und somit die Warmrißbildung unterdrückt wird.It is advantageous that the first rolling process in a multi-stage rolling process in the area the solidification interval of the alloy and is also an even one The last, not yet solidified areas of the belt are cooled and thus the Warm cracking is suppressed.
Gemäß Figur 3 ist unmittelbar im auf die Erstarrung folgenden Bereich des gegossenen
Bandes 2 eine zusätzliche Walze 5 angeordnet, die direkt gegen die Gußtrommel 3 arbeitet
und die eine zusätzliche geringfügige Verformung erzeugt, die durch Rekristallisation zu einer
isotropen Festigkeitsverteilung führt.According to FIG. 3, the area of the cast immediately following the solidification is
Bei durch Stranggießen von Bleibändern mittels Gießwalzen und nachgeschalteten Abziehwalzen ist es aus der DE-C 33 17 109 bekannt, das Band einer Zugspannung zur Erzeugung eines rekristallisierten Gefüges zu unterwerfen. Allerdings ist ein hoher technischer Aufwand notwendig, um eine konstante Zugspannung auf das aus den Abziehwalzen auslaufende Band auszuüben.In the case of continuous casting of lead strips by means of casting rolls and downstream pull-off rolls it is known from DE-C 33 17 109, the band of a tensile stress for generation subject to a recrystallized structure. However, there is a high level of technical effort necessary to maintain a constant tension on the outlet from the peeling rollers Exercise band.
Durch das erfindungsgemäße Verfahren und die einfach aufgebaute Vorrichtung zur Durchführung dieses Verfahrens wird die Mikrostruktur des Bandes verbessert, und damit die Korrosionsbeständigkeit und die mechanische Festigkeit von aus dem Band hergestellten Streckmetallgittern erhöht. Insbesondere wird die durch das Gießverfahren bedingte nachteilige Ausrichtung der Korngrößen noch während der Bandherstellung und nicht erst zu einem späteren Zeitpunkt eliminiert. Durch das Nachschalten eines oder mehrerer Walzvorgänge, bei denen das kurz zuvor erst erstarrte Gefüge ausreichend stark verformt wird, kann das Material unter der Wirkung der noch hohen Temperatur zumindest teilweise rekristallisieren.By the method according to the invention and the simply constructed device for implementation This process improves the microstructure of the belt, and thus the Corrosion resistance and mechanical strength of the tape Expanded metal grids increased. In particular, the disadvantage caused by the casting process Alignment of the grain sizes during the band production and not to one eliminated later. By connecting one or more rolling processes, in which the structure that has just solidified shortly before is deformed sufficiently, this can Recrystallize material at least partially under the effect of the still high temperature.
Dadurch, daß der nachgeschaltete Walzvorgang unmittelbar auf die Erstarrung folgt, wird beim erfindungsgemäßen Verfahren die Eigenwärme des Bandes genutzt, gegebenenfalls kann jedoch zusätzlich eine kurzzeitige Zwischen- oder Wiedererwärmung durch einen kurzen Ofentunnel oder durch flächige Wärmestrahler erfolgen. Bei der Rekristallisation wird ein globulitisches Gefüge erzeugt, das keine Vorzugslage der Korngrenzen mehr aufweist. Besonders vorteilhaft ist es, daß durch die sekundäre Rekristallisation eine Kornvergröberung auftritt, was zur gleichzeitigen Reduktion der Korngrenzenanzahl führt. Eine Verringerung der Korngrenzenanzahl hat vorteilhaften Einfluß auf die Korrosionsbeständigkeit der Elektrodengitter. Ein weiterer Vorteil des erfindungsgemäßen Verfahrens bzw. der erfindungsgemäßen Vorrichtung liegt darin, daß durch die zusätzliche Verformung eine exaktere Steuerung der Banddicke und ein Ausgleich der Banddickenschwankung ermöglicht wird.The fact that the subsequent rolling process follows the solidification immediately in the process according to the invention, the natural heat of the strip is used, if appropriate However, a brief reheating or reheating by a short Furnace tunnel or through flat heat radiators. During recrystallization, a produces a globulitic structure that no longer exhibits a preferred position of the grain boundaries. Especially It is advantageous that a grain coarsening by the secondary recrystallization occurs, which leads to a simultaneous reduction in the number of grain boundaries. A decrease in Grain limit number has an advantageous influence on the corrosion resistance of the electrode grid. Another advantage of the method according to the invention or of the invention Device is that the additional deformation more precise control of the Strip thickness and a compensation of the strip thickness fluctuation is made possible.
