Abstract
Description
Die Erfindung betrifft ein Verfahren zur Vergütung von einem mindestens eine Wandung aufweisenden Gussbauteil, insbesondere aus Leichtmetall, vorzugsweise Aluminiumgussbauteil oder Aluminiumlegierungsgussbauteil, wobei das Gussbauteil nach dem Gießen zumindest lokal wärmebehandelt wird.The invention relates to a method for the tempering of a cast component having at least one wall, in particular of light metal, preferably cast aluminum component or aluminum alloy casting component, wherein the cast component is heat-treated at least locally after casting.
Es ist bekannt, aus Aluminium hergestellte Gussbauteile nach dem Gießen einer Wärmebehandlung zu unterziehen. Hierzu werden die Gussbauteile von Gasbrennern zur Wärmebehandlung erwärmt, um gewünschte mechanische Eigenschaftsparameter als Vergütung der Gussbauteile einzustellen. Die bisherige Vorgehensweise hat sich bewährt, ist jedoch durchaus verbesserungsbedürftig, weil unter anderem fossile Brennstoffe eingesetzt werden und bei lokalen Erwärmungen die Grenzen der Erwärmungszone relativ breit, also unscharf sind.It is known to subject cast aluminum components to a heat treatment after casting. For this purpose, the cast components are heated by gas burners for heat treatment in order to set desired mechanical property parameters as compensation of the cast components. The previous procedure has proven itself, but is in need of improvement because, inter alia, fossil fuels are used and in local warming, the limits of the warming zone are relatively wide, so blurred.
Der Erfindung liegt daher die Aufgabe zugrunde, ein Vergüten von Gussbauteilen durch Wärmebehandlung zu verbessern.The invention is therefore based on the object to improve a quenching of cast components by heat treatment.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Wärmebehandlung mittels mindestens einem, zumindest einem Bereich der Wandung gegenüberliegend angeordneten Induktor induktiv erfolgt. Ein derartiger, mit elektrischem Strom betriebener Induktor ermöglicht eine sehr gezielte und präzise Wärmebehandlung in Bezug auf das Einstellen und Konstanthalten oder gewünschtem Wandern der Wärmebehandlungstemperatur, wobei im Falle von lokalen Wärmebehandlungsbereichen eine sehr scharfe Abgrenzung zu benachbarten, nicht wärmezubehandelnden Bereichen aufgrund des Induktors und der damit einhergehenden induktiven Wärmebehandlung realisierbar ist. Die Temperatursteuerung lässt sich durch Einstellen des elektrischen Stroms des Induktors ausgesprochen präzise kontrollieren, so wie dies bei den bekannten Gasbrennern nicht möglich ist. Der Induktor lässt sich der wärmezubehandelnden Wandung des Gussbauteils präzise ortsgenau zuordnen, wobei diese Positionierung nicht nur von außen her, sondern auch innerseits eines Gussbauteils erfolgen kann, wenn das Gussbauteil beispielsweise Hohlräume oder dergleichen aufweist. Durch den Betrieb des Induktors mit elektrischem Strom wird ein elektromagnetisches Feld erzeugt, das zu Wirbelströmen innerhalb der Wandung des Gussbauteils führt, wodurch eine Bauteilerwärmung eintritt.This object is achieved in that the heat treatment is carried out inductively by means of at least one, at least a portion of the wall oppositely disposed inductor. Such a powered with electric current inductor allows a very targeted and precise heat treatment in With respect to the setting and keeping constant or desired wandering of the heat treatment temperature, wherein in the case of local heat treatment areas a very sharp demarcation to adjacent, not heat treated areas due to the inductor and the associated inductive heat treatment is feasible. The temperature control can be controlled very precisely by adjusting the electrical current of the inductor, as is not possible with the known gas burners. The inductor can be assigned to the heat-treated wall of the cast component precisely precise location, which positioning can be done not only from the outside, but also inside a cast component, if the cast component has, for example, cavities or the like. The operation of the inductor with electric current creates an electromagnetic field that results in eddy currents within the wall of the cast component, thereby causing component heating.
Nach einer Weiterbildung der Erfindung ist vorgesehen, dass der Induktor ein elektromagnetisches Feld erzeugt, dessen Feldlinien senkrecht oder etwa senkrecht zu der zu erwärmenden Wandung beziehungsweise des Bereichs der zu erwärmenden Wandung verlaufen. Durch diese Maßnahme lässt sich der Bereich der Wärmebehandlung lokal scharf begrenzen, wobei die Temperatursteuerung oder -regelung der Erwärmung durch Stromsteuerung oder Stromregelung des elektrischen, dem Induktor zugeführten Stroms bewirkt wird.According to a development of the invention, it is provided that the inductor generates an electromagnetic field whose field lines are perpendicular or approximately perpendicular to the wall to be heated or the region of the wall to be heated. By this measure, the area of the heat treatment can locally sharply limit, wherein the temperature control or regulation of the heating is effected by current control or current control of the electrical current supplied to the inductor.
Wie vorstehend bereits erwähnt, ist insbesondere vorgesehen, dass ein durch den mindestens einen Induktor fließender elektrischer Strom entsprechend der gewünschten Intensität der Wärmebehandlung gesteuert oder geregelt wird.As already mentioned above, it is in particular provided that an electrical current flowing through the at least one inductor Current is controlled or regulated according to the desired intensity of the heat treatment.
Eine Weiterbildung der Erfindung sieht vor, dass mindestens ein nicht der Wärmebehandlung unterzogener Bereich des Gussbauteils zumindest während der Wärmebehandlung gekühlt wird. Die oftmals gute Wärmeleitung im Gussbauteil, insbesondere im Aluminiumgussbauteil oder Aluminiumlegierungsgussbauteil, führt zu einer Temperaturerhöhung in Bauteilbereichen, die nicht in jedem Fall erwünscht ist. Zur Unterbindung einer nicht gewünschten Erwärmung erfolgt die Kühlung im entsprechenden Bereich des Gussbauteils.A further development of the invention provides that at least one region of the cast component which is not subjected to the heat treatment is cooled at least during the heat treatment. The often good heat conduction in the cast component, in particular in the aluminum cast component or aluminum alloy cast component, leads to an increase in temperature in component areas, which is not always desirable. To prevent unwanted heating, cooling takes place in the corresponding area of the cast component.

Aufgrund dieser Maßnahme wird die Wandung demzufolge von der Vorder- und der Rückseite induktiv zur Wärmebehandlung erwärmt, wobei die Vorzüge von induktiv arbeitenden, mit elektrischem Strom betriebenen Induktoren - so wie sie vorstehend bereits erwähnt wurden - sowohl an der Vorder- also auch an der Rückseite des Gussbauteils auftreten. Durch die beidseitige Erwärmung kann diese schneller und auch homogener durchgeführt werden. Dabei ist es möglich, dass die beiden Induktoren deckungsgleich arbeiten, also gleichgroße und deckungsgleiche Bereiche der Wandung des Werkstücks wärmebehandeln, oder versetzt zueinander liegen, sodass unterschiedliche Bereiche erwärmt werden und nur ein bestimmter Anteil der Bereiche deckungsgleich ist. Es kann auch insbesondere vorgesehen sein, dass sich die beiden Bereiche nicht decken, d.h., dass die Vorderseite der Wandung des Gussbauteils mit dem ersten Induktor und dass die Rückseite des Gussbauteils mit dem zweiten Induktor zur Wärmebehandlung erwärmt werden und diese Bereiche nicht deckungsgleich sind, wobei aufgrund der von unterschiedlichen Seiten angreifenden Wärmebehandlung jedoch besondere Wärmeverläufe mit entsprechend gewünschten Parametereinstellungen erzielt werden.According to a particularly preferred embodiment of the invention, it is provided that the wall has a front side and a rear side and that at least a region of the front side is inductively heated at least with the said first inductor and that at least one region of the rear side at least with a further, second inductor is heated, wherein the areas are preferably approximately congruent or preferably congruent. Due to this measure, the wall is thus inductively heated from the front and the back for heat treatment, the advantages of inductively operating, electrically powered inductors - as they were already mentioned above - both at the front and on the back of the cast component occur. Due to the bilateral heating, this can be done faster and more homogeneous. It is possible that the two inductors work congruently, so heat-treat equal and congruent areas of the wall of the workpiece, or offset from each other lie so that different areas are heated and only a certain proportion of the areas is congruent. It can also be provided in particular that the two areas do not coincide, ie that the front side of the wall of the cast component with the first inductor and that the rear side of the cast component are heated with the second inductor for heat treatment and these areas are not congruent However, due to the attacking from different sides heat treatment special heat trajectories are achieved with correspondingly desired parameter settings.

Durch das Abschrecken lassen sich die Werkstoffparameter in gewünschter Weise beeinflussen.According to a development of the invention it is provided that the heat-treated wall or the heat-treating region of the wall is quenched after the heat treatment. By quenching the material parameters can be influenced in the desired manner.
Das erwähnte Abschrecken erfolgt vorzugsweise mittels mindestens eines gasförmigen und/oder flüssigen Mediums.The mentioned quenching is preferably carried out by means of at least one gaseous and / or liquid medium.
Nach einer Weiterbildung der Erfindung kann vorzugsweise vorgesehen sein, dass das Abschrecken/Abkühlen mittels mindestens eines Mediumsstroms erfolgt.According to a development of the invention, it can preferably be provided that the quenching / cooling takes place by means of at least one medium flow.
Bevorzugt ist es - nach einer Weiterbildung der Erfindung - dass das Abschrecken mittels Gasstromkühlung, insbesondere Luftstromkühlung und/oder Stickstoffstromkühlung, erfolgt.According to a development of the invention, it is preferred that quenching takes place by means of gas stream cooling, in particular airflow cooling and / or nitrogen stream cooling.

Nach einer Weiterbildung der Erfindung ist vorgesehen, dass die zweistufige Wärmebehandlung als zunächst erfolgendes Lösungsglühen und dann erfolgendes Warmauslagern durchgeführt wird. Die Bauteile werden also zunächst lösungsgeglüht und anschließend warmausgelagert. Die einzustellenden Temperaturparameter können ebenso - wie vorstehend erwähnt - beim Lösungsglühen im Bereich von 350°C bis 550°C und beim Warmauslagern im Bereich von 100°C bis 350°C liegen.According to a development of the invention, it is provided that the two-stage heat treatment is carried out as first solution heat treatment and then successful aging.

The temperature parameters to be set may also, as mentioned above, be from 350 ° C to 550 ° C for solution heat treatment and from 100 ° C to 350 ° C for hot aging.
Nach einer bevorzugten Ausführungsform der Erfindung ist vorgesehen, dass das Lösungsglühen nur die Wandung, nur den Bereich der Wandung oder das gesamte Gussbauteil erfasst und/oder dass das Warmauslagern nur die Wandung, nur den Bereich der Wandung oder das gesamte Gussbauteil erfasst. Demzufolge kann durch entsprechende Kombinatorik der verschiedenen, vorstehend genannten Möglichkeit ein optimales Vergüten des Gussbauteils durchgeführt werden.According to a preferred embodiment of the invention it is provided that the solution annealing covers only the wall, only the area of the wall or the entire cast component and / or that the thermal aging covers only the wall, only the area of the wall or the entire cast component.
