   Während die oben genannte Mischung zur Ableitung der Hitze aus dem Gussstück mit der richtigen Geschwindigkeit dient, kann es sich empfehlen, einen gewissen Prozentsatz an fein vorteiltem, gelbem Ton in die Mischung einzubringen, beispielsweise auf 120 Gewichtsteile Karborund und 12 Gewichtsteile Zucker 10 Gewichtsteile Ton. Ein solcher Tonzusatz verhindert das Verstopfen des Siebes durch den Zucker und   Karborund   und das Gemisch lässt sich dadurch leichter und besser formen. 
 EMI2.1 
 Gasmengen entwickeln, so empfiehlt es sich noch, fein verteilten Graphit zuzusetzen, dessen Mango von der Menge der entweichenden Gase abhängt. So kann man beispielsweise einem Gemisch von 120 Gewichtsteilen Karborund, 12 Gewichtsteilen Zucker und 10 Gewichtsteilen Ton 20 Gewichtsteile Graphit zusetzen. 



   Nach beendigter Bildung und Herausnahme des   Gussstückes   aus seiner Form kann der um das Gussstück herumliegende feste   Körper vermählen oder sonstwie in   einen fein verteilten Zustand zurückgeführt werden, um dann nach Zusatz einiger Prozente Zucker wieder   verwendet werden zu können.   



   PATENT-ANSPRÜCHE : 
1. Formmaterial, dadurch gekennzeichnet, dass dasselbe durch die Hitze des in die Form eingegossenen Metalles gut wärmeleitend und fest wird.

   While the above mixture serves to dissipate the heat from the casting at the correct speed, it can be advisable to add a certain percentage of finely divided, yellow clay to the mixture, for example 10 parts by weight of clay for 120 parts by weight of carborundum and 12 parts by weight of sugar. Such a clay addition prevents the sieve from clogging with the sugar and carborundum, and the mixture can thus be shaped more easily and better.
 EMI2.1
 Developing amounts of gas, it is also advisable to add finely divided graphite, the mango of which depends on the amount of escaping gases. For example, 20 parts by weight of graphite can be added to a mixture of 120 parts by weight of carborundum, 12 parts by weight of sugar and 10 parts by weight of clay.



   After completion of the formation and removal of the casting from its mold, the solid body lying around the casting can be ground or otherwise returned to a finely divided state so that it can then be used again after adding a few percent sugar.



   PATENT CLAIMS:
1. Molding material, characterized in that the same is highly conductive and solid due to the heat of the metal poured into the mold.

 

Claims (1)

2. Formmaterial nach Anspruch 1, dadurch gekennzeichnet, dass dasselbe aus fein verteiltem, mit Zucker vermischtem Karborund besteht und durch Zusatz einer Flüssigkeit in den plastischen Zustand übergeführt wird. 2. Molding material according to claim 1, characterized in that the same consists of finely divided carborundum mixed with sugar and is converted into the plastic state by adding a liquid. 3. Formmaterial nach anspruch 2, dadurch gekennzeichnet, dass dasselbe aus fi-in verteiltem Karborund, Zucker, Ton und eventuell fein verteiltem Graphit besteht und durch EMI2.2 3. Molding material according to claim 2, characterized in that the same consists of fi-in distributed carborundum, sugar, clay and possibly finely divided graphite and through EMI2.2
