Description

masse zur Herstellung von Dauerformen. In den Eisen- und Metallgießereien sind Sandformen, Metallformen und sogenannte Dauerformen aus keramischen Massen in Benutzung.mass for the production of permanent molds. In the iron and metal foundries are sand molds, metal molds and so-called permanent molds made of ceramic masses in use.

Vorliegende Erfindung betrifft eine Masse für Dauerformen. Eisen- oder Stahlspäne werden nach dem Sherardisier- oder Schoopschen Verfahren oder durch Galvanisation mit Zink oder Aluminium oder Ferrosilicium oder Legierungen dieser Metalle überzogen. Die so behandelten Späne werden mit wenig Zement vermischt und dann angefeuchtet als Formmasse benutzt. Der Zernent füllt die Poren nicht ganz aus, und trotzdem erhält die Masse nach dem Abbinden eine solche Festigkeit, daß die Formen das Abgießen vieler Stücke aushalten.The present invention relates to a composition for permanent molds. Iron- or steel shavings are made according to the Sherardizing or Schoop method or by Electroplating with zinc or aluminum or ferrosilicon or alloys of these Metals coated. The chips treated in this way are mixed with a little cement and then used moistened as a molding compound. The Zernent doesn't quite fill the pores off, and nevertheless the mass receives such a strength after setting that the molds can withstand the pouring of many pieces.

Ein gutes Mischungsverhältnis von Metallmasse zu Zement ist 8o : 2o. Dabei wird die Formmasse sehr fest und nach dem Trocknen im Trockenofen sehr porös. Zweckmäßig erhalten die Formen noch einen Graphitanstrich.A good mixing ratio of metal mass to cement is 8o: 2o. The molding compound becomes very solid and very porous after drying in the drying oven. The molds are also appropriately painted with graphite.

Es ist nun schon früher vorgeschlagen, gewöhnlicher Formmasse, also besonders Sand, solche Stoffe zuzusetzen, welche die Wärmeleitfähigkeit erhöhen. Nach dem Verfahren nach Patent 125334 sind diese Stoffe Kupferoxyd, Eisenhammerschlag, Metallpulver, Metallspäne und 31etallstücke. Aber eine innige Bindung zwischen der Formmasse und der Oberfläche der Zusatzstoffe findet nicht statt.It is now proposed earlier, ordinary molding compound, so especially sand to add substances that increase thermal conductivity. According to the procedure according to patent 125334, these substances are copper oxide, iron hammer blow, Metal powder, metal shavings and pieces of metal. But an intimate bond between the Molding compound and the surface of the additives does not take place.

Nach dem Verfahren der vorliegenden Erfindung wird die Oberfläche der zugesetzten Eisenspäne aus dem Grunde ganz besonders behandelt, damit der Zement beim Abbinden mit der Oberfläche der Späne eine innige Verbindung eingeht. Die Formmasse bindet ab, man kann sie .also nach dem Gebrauch nicht weiter zu anderen Formen benutzen.According to the method of the present invention, the surface the added iron filings are treated especially so that the cement forms an intimate connection with the surface of the chips when they set. The molding compound binds, so you cannot use it for other shapes after use.
