Description

Gießtrichter. Zum Eingießen von flüssigem Messing in Kokillen benutzte man bisher Trichter aus einer Stampfmasse, wie z. B. Schamotte, oder solche aus Eisen. Beide haben den Nachteil, infolge der starken Hitze des flüssigen Metalls sehr schnell zu verschleißen. Auch wurden die Löcher, durch die das flüssige Metall fließt, schon nach wenigen Güssen angegriffen, wodurch diese sich erweitern, was für den guten Ausfall der Messingplatten sehr schädlich ist.Pouring funnel. Used to pour liquid brass into molds one so far funnel from a rammed earth, such. B. chamotte, or such Iron. Both have the disadvantage, due to the intense heat of the liquid metal wear out very quickly. Also were the holes through which the molten metal flows, attacked after just a few pourings, causing them to expand, what is very detrimental to the good failure of the brass plates.

Zum einwandfreien Gießen von Metallplatten ist es von sehr großer Bedeutung, diese Löcher stets in derselben Größe und Anordnung zu halten.It is very large for the proper casting of metal plates Importance of keeping these holes the same size and arrangement.

Der Gegenstand der vorliegenden Erfindung ist ein Dauertrichter, der die Übelstände des zu schnellen Verschleißes und der zu starken Abnutzung der bisherigen Trichter beseitigt. Der Trichter ist hohlwandig ausgebildet und wird von einem Kühlmittel durchströmt. Bei Eingießen von flüssigem Metall in den Trichter wird gleichzeitig das Kühlmittel durch die Hohlwand des Trichters geleitet. Durch die ständige Wärmeabfuhr des durchgeleiteten Kühlmittels wird der Trichter stets auf der gleichen Temperatur gehalten, so daß die Innenwandungen des Trichters, die mit dem flüssigen- Metall in Berührung kommen, nicht so hoch erhitzt werden, daß das Trichtermaterial durch das flüssige Metall angegriffen würde. Auch werden die Trichterlöcher von dem durchfließenden Metall bei dem Trichter in der neuen gekühlten Ausführung in keiner Weise verändert.The object of the present invention is a continuous funnel which the evils of too rapid wear and tear and excessive wear of the previous ones Funnel eliminated. The funnel is hollow-walled and is powered by a coolant flows through. When pouring liquid metal into the funnel, it takes place at the same time the coolant passed through the hollow wall of the funnel. Due to the constant heat dissipation of the transmitted Coolant is always on the funnel kept the same temperature, so that the inner walls of the funnel that with the liquid metal come into contact, not be heated so high that the funnel material would be attacked by the molten metal. Also the funnel holes of the metal flowing through the funnel in the new cooled version in not changed in any way.

Die Kühlung des Trichters bringt also zwei bedeutende Vorteile mit sich: einmal die Beseitigung des bisherigen starken Verschleißes der Gießtrichter, dann die genaue Innehaltung der Form und Anordnung der Trichterlöcher.Cooling the funnel therefore has two significant advantages yourself: once the elimination of the previous heavy wear and tear on the pouring funnel, then the exact observance of the shape and arrangement of the funnel holes.

Der neue »Gekühlte Gießtrichter« ist in der Zeichnung in einer Ausführungsform dargestellt. Abb. z stellt'einen Längsschnitt, Abb. 3 einen Querschnitt durch den Trichter dar. In Abb. 2 ist die Ansicht des Trichters von der Eingußseite dargestellt. Das flüssige Metall a fließt durch die Trichterlöcher b in die Kokille. In den Seitenwandungen c befinden sich die Hohlräume d, durch die das Kühlmittel geleitet wird. Durch den Rohranschluß e tritt das kalte Kühlmittel von unten in den Trichter ein. Das Kühlmittel bewegt sich unter dem Drucke der nachfolgenden Mengen, etwa gemäß den gezeichneten Pfeilen durch die Hohlräume des Trichters nach oben zu dem Ausfluß f. Von hier aus wird das Kühlmittel wieder durch die Rohre g abgeführt.The new "cooled sprue" is shown in one embodiment in the drawing. Fig. Z shows a longitudinal section, Fig. 3 shows a cross section through the funnel. In Fig. 2 the view of the funnel is shown from the sprue side. The liquid metal a flows through the funnel holes b into the mold. In the side walls c are the cavities d through which the coolant is passed. The cold coolant enters the funnel from below through the pipe connection e. The coolant moves under the pressure of the following quantities, for example according to the arrows drawn, up through the cavities of the funnel to the outlet f. From here the coolant is discharged again through the pipes g.

Claims (1)

PATENTANSPRUCH: Gießtrichter, namentlich für Messingguß, dadurch gekennzeichnet, daß der Trichter doppelwandig ist und vor schädlicher Erhitzung durch ständige Zu- und Abfuhr eines Kühlmittels bewahrt wird. PATENT CLAIM: pouring funnel, specifically for cast brass, characterized in that the funnel is double-walled and is protected from harmful heating by constant supply and discharge of a coolant.
