Description
Vakuumgefäß und Verfahren zu seiner Herstellung. Bei der Evakuierung von Gefäßen, besonders bei solchen aus Metall, hat sich die Schwierigkeit ergeben, die in der Kohle befindlichen Gase sowie die dem Metall anhaftende Feuchtigkeit restlos gut zu beseitigen.Vacuum vessel and process for its manufacture. During the evacuation of vessels, especially those made of metal, the difficulty has arisen the gases in the coal and the moisture adhering to the metal completely easy to remove.
Bei Glas- und Porzellängefäßen ist dies insofern einfach, als dieselben auf hohe Temperaturen erwärmt werden können und auf diese Weise sämtliche Dämpfe leichter sich ablösen und entweichen. Bei Metallgefäßen ist eine--Erwärmung auf sehr hohe Temperaturen nicht zulässig.In the case of glass and porcelain vessels, this is easy in that they are the same can be heated to high temperatures and in this way all vapors easier to peel off and escape. In the case of metal vessels, there is a - heating up very high temperatures are not permitted.
Das vorliegende Verfahren beruht nun darin, daß in die Zwischenräume des Gefäßes dadurch eine hohe Temperatur gebracht wird, daß man die Kohlen selbst in einen hartgelöteten, mit Durchbrechungen ausgestatteten besonderen Kasten o. dgl. Behälter oder in einer Kohlenaufnahmevorrichtung vor dem Einbringen auf hohe Temperatur erhitzt und unter Vakuum von sämtlichen in 'ihr enthaltenden Gasen befreit.The present method is based on the fact that in the interstices the vessel is brought to a high temperature by the coals themselves in a special box or the like that is brazed and equipped with openings. Like. Container or in a coal receiving device before being introduced to high Temperature heated and under vacuum of all contained in it Gases released.
Wenn; nun ein derartiger _Behälter in das Gefäß (z. B. Tauchgefäß) in heißem Zustande eingebracht und - dieses schnell geschlossen wird, so entwickelt sich infolge der der Kohle noch innewohnenden Wärme indem Vakuumraum eine so hohe Temperatur, daß sie hinreicht, die an den Metallwänden kapillar anhaftende Feuchtigkeit zum Vergasen zu bringen, so d'aß sie leicht abgepumpt werden kann. Die Gase kernen, wenn das Gefäß unmittelbar daran an die Vakuumpumpe gebracht wird, nunmehr schnell abgesaugt werden.If; Now put such a container in the vessel (e.g. immersion vessel) introduced in a hot state and - this is quickly closed, so developed As a result of the heat still inherent in the coal in the vacuum space, it becomes so high Temperature that it is sufficient, the moisture adhering to the metal walls by capillary action to gasify so that it can be pumped out easily. The gases nucleate if the vessel is brought directly to the vacuum pump, now quickly be sucked off.
Das Verfahren hat den Vorteil, daß ein erheblicher Teil der Pumparbeit gespart werden kann.The method has the advantage that a considerable part of the pumping work can be saved.
Nach der vorliegenden Ausführung kann man den besonderen Kohlenbehälter vorteilhaft allein in den Vakuumofen bringen, zum Entgasen.According to the present embodiment, you can use the special coal container it is advantageous to bring it alone into the vacuum furnace for degassing.
An Stelle eines hartgelöteten Kastens bzw. Kohlen- oder Absorptionsbehälters kann man gegebenenfalls auch einen solchen aus Porzellan oder aus dergleichen keramischer Masse verwenden, wobei das Vakuumgefäß an und für sich aus Metall hergestellt sein kann. Die Form des Absorptionsbehälters maßt man dem Vakuumgefäß an.Instead of a brazed box or charcoal or absorption container you can optionally also one made of porcelain or of the like ceramic Use mass, the vacuum vessel in and of itself being made of metal can. The shape of the absorption container is matched to the vacuum vessel.
Bei kugelförmigen Gefäßen wird man den Absorptionsbehälter segmentartig ausführen USW. In the case of spherical vessels, the absorption container will be designed in segments, etc.
