Patentiert im Deutschen Reiche vom 13. März 1912 ab.Patented in the German Empire on March 13, 1912.
Die Benutzung von Gußeisen zur Herstellung der Mahlorgane von Holländern, Papierstoffmühlen und ähnlichen Mahlgängen ist bekannt. Es hat sich nun herausgestellt, daß solche Mahlwerkzeuge eine poröse und gegebenenfalls kristallinische Struktur besitzen müssen, so daß sie einerseits sehr haltbar sind und andererseits die Fasern soviel wie möglich schonen. Das neue Verfahren zur Herstellung eines solchen Materials besteht darin, daß bei dem Guß dieser Werkzeuge schmelzbare Gegenstände, wie Drahtnetze, Drehspäne o. dgl., in der Gießform angebracht werden, so daß beim Eingießen der Metallmasse in die Gießform in der geschmolzenen Masse eine Bewegung entsteht. Hierdurch wird eine Blasenbildung hervorgerufen, die die Masse porös macht.The use of cast iron for the manufacture of Dutch grinding elements, paper pulp mills and similar grindings are known. It has now been found that such grinding tools have a porous and possibly must have a crystalline structure, so that they are on the one hand very durable and on the other hand, protect the fibers as much as possible. The new method of manufacture One such material is that when these tools are cast, fusible Objects such as wire nets, turnings, etc., are placed in the mold, so that when pouring the metal mass into the mold in the molten mass a Movement arises. This causes the formation of bubbles, which the mass makes porous.
Das Verfahren wird zweckmäßig in der Weise ausgeführt, daß in den Formen Drehspäne oder Drahtnetze in Abständen voneinander angebracht werden, worauf die geschmolzene Masse eingegossen wird. Da diese Masse aber die in die Form hineingelegten Gegenstände mit niedriger Temperatur berührt, entsteht in der geschmolzenen Masse eine Bewegung, die eine Blasenbildung in "dem Material bewirkt, so daß das Material porös wird.The method is expediently carried out in such a way that turnings are deposited in the molds or wire nets are attached at intervals, after which the melted Mass is poured. But since this mass is the objects placed in the mold touched at a low temperature, a movement is created in the molten mass, which causes bubbles to form in the material so that the material becomes porous.
