Abstract
Gegenstand der Erfindung ist ein Verfahren zur Herstellung eines Kern- und/oder Formsandes für Gießereizwecke. Dabei wird ein granularer mineralischer Formgrundstoff mit einem Additiv sowie einem anorganischen Bindemittel gemischt. Erfindungsgemäß wird als Additiv ein anorganisches Blähadditiv mit einer Blähzahl von wenigstens 9 eingesetzt, also einer höheren Blähzahl als sie für Kohle erreicht wird. Alternativ kann auch mit einem anorganischen Additiv gearbeitet werden, beispielsweise mit makrokristallinen Graphit, wobei die Fertigmischung aus dem Formgrundstoff, dem Additiv und dem Bindemittel bis zu einer Dichtezunahme von wenigstens 20 g/dm3 kompaktiert wird. The invention relates to a method for producing a core and / or foundry sand for foundry purposes. In this case, a granular mineral molding material is mixed with an additive and an inorganic binder. According to the invention, the additive used is an inorganic bulking additive having a Blähzahl of at least 9, ie a higher Blähzahl than it is achieved for coal. Alternatively, it is also possible to work with an inorganic additive, for example with macrocrystalline graphite, the finished mixture of the molding base material, the additive and the binder being compacted to a density increase of at least 20 g / dm 3 .
