Description

Gußeiserne glatte Walze für die Tonwarenindustrie Bei der Verwendung von Walzen für Ziegeleien o. dgl. hat es sich als nachteilig herausgestellt, daß infolge der ungleichmäßigen Abnutzung der in Kokillen erzeugten Hartgußstücke einerseits die durch das Walzgut stark beanspruchten mittleren Teile der Walzen eine unregelmäßige, vertiefte Oberfläche erhielten, andererseits die infolgedessen besonders stark auf Druck seitens der Gegenwalze beanspruchten Randteile sich sehr stark erwärmten, wodurch hier Haarrisse und Abschieferungen entstanden, die die Walzen völlig unbrauchbar machten.Cast iron smooth roller for pottery industry in use of rollers for brickworks o. The like. It has been found to be disadvantageous that due to the uneven wear of the chilled castings produced in molds on the one hand the central parts of the rolls, which are heavily stressed by the rolling stock, have an irregular, recessed surface, on the other hand, which is particularly strong as a result Edge parts exposed to pressure from the counter roller became very hot, which caused hairline cracks and flaking that made the rollers completely unusable did.

Es ist auch schon vorgeschlagen worden, in Ziegeleien o. dgl. gerippte Walzen. mit einer Bewehrung aus Draht, Ketten o. dgl. zu benutzen, wobei diese Bewehrung nach Verschleißen immer wieder erneuert werden konnte. Es leuchtet aber ein, daß eine solche Maßnahme eine sehr erhebliche Erschwerung und sogar Gefährdung des Betriebes mit sich bringen muß. Andererseits ist es auch bekannt, Formwalzen so herzustellen, daß durch verschiedene Ausgestaltung der Gußform, die z. B. an den Spitzen der Walzen in der eisernen Kokille ringartige Stücke aus wärmesperrendem. Baustoff eingelegt erhielt, nur diese Spitzen ein feineres Kristallgefüge aufwiesen. Solche Formwalzen kommen` für das Zerkleinern bildsamer Massen, insbesondere von Ton, nicht in Betracht.It has also been suggested that ribs be used in brickworks or the like Rollers. with a reinforcement made of wire, chains or the like. To use, this reinforcement could be renewed again and again after wearing out. But it makes sense that Such a measure would make the operation very difficult and even endanger it must bring with it. On the other hand, it is also known to produce forming rollers in such a way that that through various configurations of the mold, the z. B. at the tips of the rollers in the iron mold, ring-like pieces of heat-blocking. Building material inserted received, only these tips had a finer crystal structure. Such forming rolls are not suitable for crushing malleable masses, especially clay.

Um nun allen diesen Unannehmlichkeiten aus dem Wege zu gehen, verfährt man nach vorliegender Erfindung so, daß man zu dem in Rede stehenden Zweck gußeiserne glatte Walzen mit einer Oberfläche verwendet, die in ihren mittleren Teilen aus Hartguß, in ihren Randteilen aus Grauguß bestehen. Diese werden in an sich bekannter Weise so hergestellt, daß man beim Gießen der eigentlichen Kokille oben und unten noch Einsätze oder Aufsätze aus Lehm oder Sand gibt.In order to avoid all these inconveniences, proceed one according to the present invention so that one cast iron for the purpose in question smooth rollers with a surface that is made up in their central parts Chilled cast iron, made of gray cast iron in their edge parts. These become better known in and of themselves Way made so that when casting the actual mold above and below there are still inserts or attachments made of clay or sand.
