Description

Die Erfindung betrifft eine Eingussvorrichtung für Metallschmelzen.The invention relates to a pouring device for molten metal.

Gemäß dem Stand der Technik werden große Gussteile beispielsweise für Windenergieanlagen derart eingeformt, dass das flüssige Metall durch einen oder mehrere Filter oder Filtersysteme zugeführt wird.According to the state of the art, large castings, for example for wind turbines, are formed in such a way that the liquid metal is supplied through one or more filters or filter systems.

Bei den großen Gussteilen handelt es sich um Gussteile, die von einer bis beispielsweise 70 Tonnen Gewicht aufweisen können.The large castings are castings, which may have a weight of up to, for example, 70 tons.

Die Schlacke ist leichter als Metall, das heißt, Metall hat eine deutlich größere Dichte als Schlacke.The slag is lighter than metal, that is, metal has a much greater density than slag.

Das der Erfindung zugrunde liegende Problem besteht darin, eine Eingussvorrichtung anzugeben, mit der eine Strömungsbeeinflussung optimiert wird, in der darüber hinaus in sehr hohem Maße Schlacke abgesondert wird und die zusätzlich Turbulenzen der Schmelze bei der Formfüllung vermeidet.The problem underlying the invention is to provide a sprue with which a flow control is optimized, in addition to the slag is separated to a very high degree and avoids the additional turbulence of the melt in the mold filling.

Dieses technische Problem wird durch eine Eingussvorrichtung mit den Merkmalen des Anspruches 1 gelöst.This technical problem is solved by a pouring device with the features of claim 1.

Die erfindungsgemäße Eingussvorrichtung für Metallschmelzen mit wenigstens einer Einlassöffnung und wenigstens einer Auslassöffnung zeichnet sich dadurch aus, dass in der Eingussvorrichtung zwischen der wenigstens einen Einlassöffnung und der wenigstens einen Auslassöffnung wenigstens ein Fließweg für die Metallschmelze ausgebildet ist und dass der Fließweg mittels wenigstens eines Steges wenigstens einmal um wenigstens 90° umgelenkt ausgebildet ist.The molten metal casting device according to the invention having at least one inlet opening and at least one outlet opening is characterized in that at least one flow path for the molten metal is formed in the sprue device between the at least one inlet opening and the at least one outlet opening and the flow path is at least once by means of at least one ridge is formed deflected by at least 90 °.

Durch die Umlenkung des Fließweges wenigstens einmal um wenigstens 90° wird erreicht, dass Turbulenzen bei der Formfüllung vermieden werden. Darüber hinaus wird die Strömung optimal beeinflusst. Zusätzlich wird Schlacke besonders gut abgesondert.By deflecting the flow path at least once by at least 90 ° is achieved that turbulence in the mold filling can be avoided. In addition, the flow is optimally influenced. In addition, slag is separated very well.

Gemäß einer besonders bevorzugten Ausführungsform der Erfindung wird der Fließweg wenigstens einmal um 180° umgelenkt.According to a particularly preferred embodiment of the invention, the flow path is deflected at least once by 180 °.

Es besteht jedoch auch die Möglichkeit, andere Winkelbereiche vorzusehen.However, it is also possible to provide other angular ranges.

Gemäß der Erfindung wird eine Eingussvorrichtung für Metallschmelzen angegeben, welche einen oder mehrere Zuläufe (Einlassöffnungen) und einen oder mehrere Abläufe (Auslassöffnungen) aufweisen können, und bei der die Metallschmelze in ihrer Flussrichtung in der Eingussvorrichtung wenigstens einmal um 180° umgelenkt wird, bevor sie ausgeleitet wird. Vorteilhaft sind wenigstens zwei Umlenkungen von jeweils 180° vorgesehen. Es besteht jedoch die Möglichkeit, bis zu sieben oder acht Umlenkungen oder sogar noch mehr Umlenkungen vorzusehen. Die Umlenkungen können jedoch auch andere Winkelbereiche als 180° aufweisen, beispielsweise 120°, 150° oder dergleichen.According to the invention, a molten metal pouring device is provided, which may have one or more inlets (inlet openings) and one or more outlets (outlet openings), and in which the molten metal in its flow direction in the pouring device is deflected at least once by 180 ° before it is discharged. Advantageously, at least two deflections of 180 ° are provided. However, there is the possibility to provide up to seven or eight deflections or even more deflections. However, the deflections may also have other angular ranges than 180 °, for example 120 °, 150 ° or the like.

Vorteilhaft ist der wenigstens einen Einlassöffnung ein Einlassbereich nachgeordnet, und der Einlassbereich weist einen größeren Querschnitt auf als die wenigstens eine Einlassöffnung.Advantageously, the at least one inlet opening is arranged downstream of an inlet area, and the inlet area has a larger cross section than the at least one inlet opening.

Gemäß einer vorteilhaften Ausführungsform der Erfindung weist die erfindungsgemäße Eingussvorrichtung wenigstens eine Querschnittsänderung im Fließweg der Metallschmelze auf. Durch die Querschnittsvergrößerung oder auch durch Einbau von Bauteilen mit geeigneten Geometrien wird die Strömungsgeschwindigkeit deutlich verlangsamt. Das bedeutet, dass sich die Schlacke absetzen kann. Die erfindungsgemäße Eingussvorrichtung wirkt in diesem Falle als Strömungsregulator.According to an advantageous embodiment of the invention, the sprue device according to the invention has at least one change in cross section in the flow path of the molten metal. The cross-sectional enlargement or the incorporation of components with suitable geometries significantly slows down the flow velocity. This means that the slag can settle. The sprue device according to the invention acts in this case as a flow regulator.

Durch die Strömungsregulation erhält man eine Filtrationswirkung. Zusätzlich können Keramikfilter vorgesehen sein, und zwar jede Art von handelsüblichen Keramikfiltern.The flow regulation gives a filtration effect. In addition, ceramic filters may be provided, any type of commercial ceramic filter.

Wesentlich ist die Durchschnittsvergrößerung im Einlassbereich der Eingussvorrichtung. Vorteilhaft sind die nachfolgenden Querschnittsänderungen von Querschnittsbereichen in der Eingussvorrichtung ebenfalls derart ausgebildet, dass sich die Querschnitte der Querschnittsbereiche jeweils zum vorhergehenden Querschnittsbereich vergrößern.The average increase in the inlet area of the pouring device is essential. Advantageously, the subsequent cross-sectional changes of cross-sectional areas in the pouring device are likewise designed such that the cross sections of the cross-sectional areas increase in each case to the preceding cross-sectional area.

Es besteht jedoch auch die Möglichkeit, wenigstens einen nachfolgenden Querschnittsbereich gleich groß oder sogar mit kleineren Querschnitten auszubilden.However, it is also possible to form at least one subsequent cross-sectional area of equal size or even with smaller cross-sections.

Gemäß einer bevorzugten Ausführungsform der Erfindung ist der Einlassbereich der Eingussvorrichtung im Querschnitt größer ausgebildet als die Einlassöffnung.According to a preferred embodiment of the invention, the inlet area of the pouring device is made larger in cross-section than the inlet opening.

Die nachfolgenden Querschnittsbereiche in dem Fließweg sind vorteilhaft jeweils erweitert zu den vorhergehenden Querschnittsbereichen ausgebildet. Vorteilhaft sind die Querschnitte in Richtung Auslassöffnung jeweils gegenüber den vorhergehenden Querschnittsbereichen vergrößert.The following cross-sectional areas in the flow path are advantageously formed in each case extended to the previous cross-sectional areas. Advantageously, the cross sections in the direction of the outlet opening are each enlarged relative to the preceding cross-sectional areas.

Hierdurch erhält man eine optimale Strömungsregulation in der Eingussvorrichtung.This gives optimum flow regulation in the pouring device.

Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung weist eine Innenwandung der Eingussvorrichtung Unebenheiten auf. Durch die Unebenheiten kann die Schlacke oder können nicht metallische Einschlüsse besser an der Eingussvorrichtung anhaften und werden nach Absetzen an der Innenwandung nicht von der durchfließenden Schmelze mitgerissen.According to a further advantageous embodiment of the invention, an inner wall of the pouring device has unevenness. As a result of the unevenness, the slag or non-metallic inclusions can better adhere to the sprue device and are not entrained by the flowing melt after settling on the inner wall.

In der erfindungsgemäßen Eingussvorrichtung können vorteilhaft Filter angeordnet sein. Die Eingussvorrichtung kann jedoch auch ohne Filter ausgebildet sein.In the sprue device according to the invention may advantageously be arranged filters. However, the sprue device can also be designed without a filter.

Werden Filter eingesetzt, können vorteilhaft poröse Keramikfilter eingesetzt werden. An oder vor diesen Keramikfiltern setzt sich die Schlacke fest. Es besteht jedoch auch die Möglichkeit, andere handelsübliche Filter einzusetzen beziehungsweise andersartige Strömungsbremsen.If filters are used, advantageously porous ceramic filters can be used. On or before these ceramic filters, the slag is fixed. However, it is also possible to use other commercially available filters or other types of flow brakes.

Gemäß einer weiteren vorteilhaften Ausführungsform der Erfindung ist der Fließweg der Eingussvorrichtung wenigstens teilweise mit Polystyrol gefüllt ausgebildet. Zum einen dient die Polystyrolfüllung dazu, dass beim Transport des Filters zum Einsatzort kein Schmutz in den Filter gelangen kann.According to a further advantageous embodiment of the invention, the flow path of the pouring device is at least partially filled with polystyrene. On the one hand, the polystyrene filling serves to prevent dirt from entering the filter when the filter is being transported to the place of use.

Zum anderen verbrennt das Polystyrol bei Einleiten der Schmelze in die Eingussvorrichtung. Durch den Gasdruck beim Verbrennen erfolgt ein Abbremsen der Schmelze, was sich wiederum vorteilhaft auf die Strömungsgeschwindigkeit auswirkt.On the other hand, the polystyrene burns when the melt is introduced into the pouring device. Due to the gas pressure during combustion, the melt is decelerated, which in turn has an advantageous effect on the flow velocity.

Eine weitere vorteilhafte Ausführungsform der Erfindung sieht vor, dass in der wenigstens einen Einlassöffnung oder einen Auslassöffnung wenigstens ein Reduzierstück angeordnet ist. Hierdurch wird der Durchmesser der Öffnungen variabel an die Eingussrohre angepasst.A further advantageous embodiment of the invention provides that at least one reducing piece is arranged in the at least one inlet opening or one outlet opening. As a result, the diameter of the openings is variably adapted to the sprues.

Das Vermeiden von Turbulenzen ist vorteilhaft, da durch Turbulenzen eine Reoxidation des Eisens in der Schmelze stattfindet. Das Magnesium, welches in der Schmelze vorhanden ist, reagiert mit dem Luftsauerstoff. Durch die Reoxidation des Eisens entwickelt sich Dross (Schlacke).The avoidance of turbulence is advantageous since turbulence causes reoxidation of the iron in the melt. The magnesium, which is present in the melt, reacts with the atmospheric oxygen. By the reoxidation of iron develops Dross (slag).

Vorteilhaft ist die Vorrichtung aus verschiedenen Bauteilen zusammengesetzt, so dass sie relativ einfach aufgebaut werden kann.Advantageously, the device is composed of various components, so that they can be relatively easily constructed.

Die Vorrichtung kann aus Schamotte, Feuerfestmasse, Stampfmasse, Kernsand und/oder Formsand gebildet sein.The device may be formed of chamotte, refractory material, ramming mass, core sand and / or foundry sand.

Fig. 1 zeigt eine Eingussvorrichtung 1 mit einem Einlass 2 und einer Einlassöffnung 31 und Auslässen 3, 4 mit Auslassöffnungen 32 zum Ein- und Ausleiten einer Metallschmelze (nicht dargestellt). In der Eingussvorrichtung 1 ist ein Fließweg 27 vorgegeben. Hierzu sind Ringstege 33 vorgesehen. Fig. 1 shows a pouring device 1 with an inlet 2 and an inlet opening 31 and outlets 3, 4 with outlet openings 32 for introducing and discharging a molten metal (not shown). In the pouring device 1 a flow path 27 is specified. For this purpose, ring lands 33 are provided.

Ein dem Einlass 2 nachgeordneter Einlassbereich 5 weist einen deutlich vergrößerten Querschnitt gegenüber dem Einlass 2 auf, so dass die Strömungsgeschwindigkeit der Metallschmelze verlangsamt wird. In Bereichen 6, 7 wird die Metallschmelze um 180° umgelenkt. Weitere Umlenkungen um jeweils 180° erfolgen in Bereichen 8, 9; 10, 11.An inlet region 5 downstream of the inlet 2 has a significantly enlarged cross-section with respect to the inlet 2, so that the flow velocity of the molten metal is slowed down. In areas 6, 7, the molten metal is deflected by 180 °. Further deflections by 180 ° take place in areas 8, 9; 10, 11.

Die nachfolgenden Querschnittsbereiche 34, 35, 36 weisen jeweils einen größeren Querschnitt auf als der vorhergehende Bereich, das heißt, der Querschnittsbereich 35 weist einen größeren Querschnitt als der Querschnittsbereich 34 und der Querschnittsbereich 36 weist einen größeren Querschnitt als der Querschnittsbereich 35 auf.The following cross-sectional areas 34, 35, 36 each have a larger cross-section than the preceding area, that is, the cross-sectional area 35 has a larger cross-section than the cross-sectional area 34 and the cross-sectional area 36 has a larger cross-section than the cross-sectional area 35.

Durch die Verlangsamung der Strömung der Metallschmelze im Bereich 5 und in den nachfolgenden Querschnittsbereichen 34, 35, 36 setzt sich Schlacke aufgrund des Dichteunterschiedes im oberen Bereich der Eingussvorrichtung 1 ab.Due to the slowing down of the flow of the molten metal in the area 5 and in the following cross-sectional areas 34, 35, 36, slag settles in the upper area of the pouring device 1 due to the density difference.

Fig. 4 shows a pouring device 1 with an inlet opening 2 and two outlets 3, 4. An inlet region 5 has a relation to the inlet 2 enlarged cross section.

Der Einlass 2 weist einen Querschnitt A1 (Ringöffnung) auf. Dem Einlassbereich nachgeordnet sind in einem Fließweg 27 vergrößerte Querschnitte A2, A3. Der Querschnitt A4 ist größer als der Querschnitt A3 und der Querschnitt A3 ist größer als der Querschnitt A2. Der Querschnitt A2 ist größer als der Querschnitt A1.
