Description

Verfahren -zum Anwärmen von Gießtrichtern Das Anwärmen von Gießtrichtern, wie sie zum Füllen von Granaten Verwendung finden, wurde bislang so durchgeführt, daß man diese Gießtrichter entweder auf Wärmeplatten stellte oder sie mit warmem Wasser behandelte. Auch beheizbare Gießtrichter wurden bereits vorgesehen, um die beim Gießen auftretenden Schwierigkeiten zu vermindern. Alle diese bekannten Arbeitsweisen zeigen aber beträchtliche Mängel. Im ersteren Falle ist die Erwärmung sehr ungleichmäßig, was das einwandfreie Vergießen der geschmolzenen Sprengstoffe mit großen Schwierigkeiten verknüpft. Bei der zweiten Arbeitsweise läßt es sich niemals völlig vermeiden, daß Wasser in die Granathülsen gelangt, das nur sehr schwer durch langwierige Trockenprozesse wieder entfernt werden kann. Die Verwendung von beheizbaren Gießtrichtern wiederum erweist sich deshalb in hohem Maße umständlich, weil die Gießtrichter jeweils von Fall zu Fall an eine Heizquelle neu angeschlossen werden müssen, was naturgemäß eine starke Begrenzung der Produktion mit sich bringt. Diese drei Methoden sind daher unzulänglich.Procedure - for heating pouring funnels The heating of pouring funnels, how they are used to fill grenades has so far been carried out that you put these sprues either on hot plates or with warm Water treated. Heatable pouring funnels have also been provided for the to reduce difficulties encountered during casting. All of these known ways of working but show considerable shortcomings. In the former case the heating is very uneven, what the proper casting of the molten explosives with great difficulty connected. In the second way of working, it can never be completely avoided that Water gets into the garnet cases, which is very difficult due to lengthy drying processes can be removed again. The use of heatable pouring funnels, on the other hand proves to be very cumbersome because the pouring funnel is each of In some cases, they have to be reconnected to a heating source, which of course imposes a severe limitation on production. These three methods are therefore inadequate.

Es hat sich nun ergeben, daß man zu einer schnelleren und gleichmäßigeren Anwärmung gelangen kann, wenn man in einer geeigneten Vorrichtung das Anwärmen mittels warmer Luft vornimmt. Es ist dabei für die bessere Wärmeübertragung von Bedeutung, daß man die Warmluft innerhalb des Anwärmschrankes durch eine geeignete Umwälzvorrichtung in schneller Bewegung hält, wodurch der Wärmeübergang auf die Füllschrauben verbessert und damit wieder die Anwärmzeit abgekürzt wird.It has now been found that one can move faster and more evenly Heating can get if one uses the heating in a suitable device warm air. It is important for better heat transfer, that the warm air inside the heating cabinet through a suitable circulation device keeps moving quickly, which improves the heat transfer to the filling screws and thus the warm-up time is again shortened.

Gleichzeitig wird auch dadurch erreicht, daß die einzelnen Gießtrichter viel gleichmäßiger angewärmt werden. Die Wirkungsweise läßt sich dadurch noch weiter verbessern, daß die Gießtrichter selbst mittels einer geeigneten Transportvorrichtung durch den Anwärmschrank hindurchgeführt werden. Hiermit wird erreicht, daß alle Gießtrichter einer vollständig einheitlichen Einwirkung der warmen Luftströmung ausgesetzt sind und daß am Ende des Transportweges voll= kommen gleichmäßig angewärmte Gießtrieb ter dem Anwärmschrank entnommen werden Die Anwärmluft wird hierbei durch geeignete und bekannte Vorrichtungen auf jede gewünschte Temperatur einreguliert.At the same time it is also achieved that the individual pouring funnel be warmed much more evenly. The mode of action can be extended even further improve that the sprue itself by means of a suitable transport device be passed through the heating cabinet. This achieves that all sprues have a completely uniform exposure to the warm air flow are exposed and that at the end of the transport route fully = come evenly heated The casting drive can be removed from the heating cabinet suitable and known devices regulated to any desired temperature.
