Damit eine Legirung den vollkommensten Grad von Homogenität besitze, ist es ein wesentliches Erfordernifs, das flüssige Metallgemisch längere Zeit hindurch auf das Sorgfältigste umzurühren. Der Erfinder bewerkstelligt dieses durch die Anwendung , eines Rührers, an dessen unterem Ende ein Stück dichten Kalksteines (Marmor oder eine andere Kohlensäure entwickelnde Verbindung) eingesetzt ist, wobei das mit grofser Gewalt sich entwickelnde Kohlensäuregas die Mischung auf die denkbar vollkommenste Weise bewirkt.In order for an alloy to have the most perfect degree of homogeneity, it is a It is essential that the liquid metal mixture be carefully handled over a long period of time stir. The inventor accomplishes this by using a stirrer, at the lower end of which a piece dense limestone (marble or another carbonic acid developing compound) is used where the carbonic acid gas evolving with great force breaks the mixture effected in the most perfect way imaginable.
Es ist kein selten vorkommender Fall, dafs Gufsstücke hier und da poröse Stellen zeigen, trotz gewissenhaftester Beobachtung aller zu deren Verhütung bekannten Vorsichtsmafsregeln. Aller Wahrscheinlichkeit nach kann jener Uebelstand zurückgeführt werden auf das Vorhandensein von Gasarten, welche in dem geschmolzenen Metall absorbirt waren. Ist solches in der That der Fall, so leuchtet es ein, dafs diese durch· die Kohlensäure entfernt werden müssen. Von der Kohlensäure selbst bleibt bekanntermafsen in dem Metall nichts zurück.It is not uncommon for castings to show porous areas here and there, despite the most conscientious observation of all known precautionary measures for their prevention. All It is probable that that condition can be traced back to its presence of kinds of gases absorbed in the molten metal. Is such a thing indeed If so, it is evident that these must be removed by the carbonic acid. from as is known, nothing remains of the carbonic acid itself in the metal.
Endlich gestattet die Anwendung erwähnten Rührers, auf einfache Weise das Ausgiefsen des Metalles unter dem schützenden Einflufs des Kohlensäuregases vornehmen zu können und so dasselbe von einer Aufnahme von Sauerstoff aus der Luft zu bewahren.Finally, the use of the stirrer mentioned allows the pouring out of the To be able to make metal under the protective influence of the carbonic acid gas and so on to preserve the same from an absorption of oxygen from the air.
