Description

In dem Patent 596 501 ist ein Verfahren zum Einschmelzen von Metall in keramische Körper beschrieben, welches darin besteht, daß in einem über dem keramischen Körper angeordneten Tiegel Metallstücke leingelegt werden, die während des Garbrandes in dem Tiegel schmelzen und dann in einen Hohlraum des darunter befindlichen keramischen Körpers fließen.In patent 596,501 is a method for melting metal into ceramic bodies, which consists of that metal pieces are placed in a crucible arranged above the ceramic body which melt in the crucible during the cooking firing and then into a cavity of the underlying ceramic body flow.

Nach diesem Verfahren können jedoch nur solche Metalle geschmolzen werden, die einen niedrigeren oder der Sinterungstemperatur des keramischen Körpers gleichen Schmelzpunkt haben.However, this method can only be used to melt metals which a lower temperature or equal to the sintering temperature of the ceramic body Have melting point.

Für besondere Zwecke ist aber die Vierwendung von hochwertigerem und mechanisch widerstandsfähigerem Metall, wie beispielsweise Stahlguß, erforderlich. Das Schmelzen dieser Metalle erfordert aber zum Teil höhere ao Temperaturen als die Sinterungsternpieratur des keramischen Körpers.For special purposes, however, is the four-turn of higher quality and mechanically more resistant metal, such as Cast steel, required. However, the melting of these metals sometimes requires higher ones ao temperatures than the sintering star temperature of the ceramic body.

Gemäß der Erfindung werden deshalb dem Tiegel, der das Schmelzmetall aufnimmt, Koksstücke beigegeben. Durch die Einwirkung dieser Koksstücke ergibt sich eine zusätzliche Wärmequelle, durch welche die Schmelztemperatur erhöht wird.According to the invention, therefore, the crucible that receives the molten metal, Pieces of coke added. The action of these pieces of coke results in a additional heat source through which the melting temperature is increased.

Gegenüber den bisher bekannten VerfahrenCompared to the previously known method

zum Einschmelzen von Metall in keramische Körper bedeutet das vorliegende Verfahren einen wesentlichen Fortschritt, da infolge der höheren. Temperatur hochwertigere Metalle geschmolzen werden können, die mechanisch höheren Anforderungen standhalten. Dies ist besonders von Vorteil für elektrische Iso-Eerkörper, wie Hängeisolatoren, an die ständig höhere Anforderungen in mechanischer Beziehung gestellt werden.for melting metal into ceramic bodies means the present method a substantial advance, as a result of the higher. Temperature higher quality metals can be melted that withstand higher mechanical requirements. This is particularly advantageous for electrical insulation bodies, such as suspension insulators, to which constantly higher demands are made in mechanical relation.

In der beiliegenden Zeichnung ist α der keramische Körper, b das Schmelzmetall, c sind die Koksstücke. Durch die Einwirkung' der Hitze des keramischen Brandes und der Koksstücke werden die Metallstücke geschmolzen, die nach· dem Flüssigwerden in den darunter befindlichein Hohlraum d des keramischen Körpers fließen.In the accompanying drawing, α is the ceramic body, b is the molten metal, and c is the coke pieces. The action of the heat of the ceramic fire and the coke pieces melts the metal pieces which, after becoming liquid, flow into the hollow space d of the ceramic body located below.

Auch bei Verwendung von Metall, dessen Schmelzpunkt unter der Sinteruingstempieratur des keramischen Körpiers liegt, ist die Beigabe von Koksstücken vorteilhaft, da hierdurch der Guß geläutert und in besserer Beschaffenheit erschmolzen wird.Even when using metal, the melting point of which is below the sintering temperature of the ceramic body is located, the addition of coke pieces is advantageous, as this the casting is refined and melted in a better quality.
