Description

1Vlodellmasse. Zur Herstellung von Modellen für die Eisengießerei hat man an Stelle des Holzes z. B. Cips, Steinmasse oder Harze vorgeschlagen. Derartige Modelle sind sehr schwer und spröde, somit leicht zerbrechlich und schwer oder gar nicht zu bearbeiten. Harzmode_lz werden besonders wegen der leichten Schmelzbarkeit nach Gebrauch kaum wieder zu verwenden sein.1 Model dimensions. For the production of models for the iron foundry one has in place of the wood z. B. Cips, stone mass or resins are proposed. Such Models are very heavy and brittle, thus easily fragile and heavy or even not edit. Harzmode_lz are especially popular because of their easy meltability can hardly be used again after use.

Gemäß der Erfindung besteht die Masse aus entfettetem Teer oder Asphalt und ergibt somit ein steinkohlenartiges, schmelzbares Erzergnis. Aus diesem können dann Modelle jeglicher Art gegossen werden, ohne Formpuder zu benö:igen, und die Modelle- sind sofort gebrauchsfertig. Auch ist die Gebrauchsdauer fast unbegrenzt. Das Material ist nicht spröde, kann leicht bearbeitet werden und ist gegen Temperaturwechsel unempfindlich. Wasseraufsaugungsfähigkeit ist nicht vorvorhanden und das Schwindmaß äußerst niedrig. Sind derartige Modelle unbrauchbar, dann kann die Masse wieder eingeschmolzen werden. Bindet man Teer mit Gips ab und setzt noch Graphit hinzu, dann sind derartige Formen unverwüstlich.According to the invention, the mass consists of degreased tar or asphalt and thus results in a coal-like, fusible product. For this you can then models of any kind can be cast without the need for molding powder, and the Models are ready to use immediately. The service life is also almost unlimited. The material is not brittle, can be easily processed and is resistant to temperature changes insensitive. There is no water absorbency and the degree of shrinkage extremely low. If such models are unusable, then the mass can again be melted down. If you bind tar with gypsum and add graphite, then such forms are indestructible.
