Description
Stahlgußformmasse nach Patent 600343 Bei Stahlgußformmassen wird größtenteils Schamotte, und zwar in verschiedenartigster Beschaffenheit, als Grundmasse verwendet. Bei Trockenstahlgußformmasse kommt als Grundmasse Schamotte in gekörnter Form, z. B. in einer Korngröße von etwa i bis 4 mm und darüber, zur Anwendung. Als Füllstoffe kommen Schamotte, Quarz u. dgl. in mehl- oder sandförmigem Zustande in Betracht.Steel casting molding compound according to patent 600343 In the case of steel casting molding compounds, for the most part Chamotte, in a wide variety of properties, is used as a base material. In the case of dry steel casting molding compound, the base compound is chamotte in granular form, e.g. B. in a grain size of about 1 to 4 mm and above, for use. As fillers chamotte, quartz and the like in the form of flour or sand come into consideration.
Durch das Patent 6oo 343 ist der Vorschlag bekanntgeworden, an Stelle von Schamotte als Grundmasse in der Natur vorkommende rohe, feuerfeste Mineralien, wie Quarzit, Dolomite o. dgl., zu verwenden. In diesem Falle liegt es nahe, den bei der Zerkleinerung unvermeidlich abfallenden Staub bziv. Mehl als Füllstoff mit zu benutzen und dadurch eine in sich gleichwertige Masse zu erzielen. Eingehende Versuche haben jedoch ergeben, daß die Verwendung von mehl- oder staubförmigem Quarzit als Füllstoff schädlich und nachteilig wirkt, denn es hat sich gezeigt, daß der staub- oder mehlförmige Quarzit mit den Alkalien des Bindemittels sich zu einem starken Flußmittel vereinigt und die Anbrennung der Formmasse verursacht. In der Technik bezeichnet man diese Erscheinung allgemein als Pflasterbildung.The proposal became known through the patent 6oo 343, instead naturally occurring raw, refractory minerals made from fireclay as a base material, such as quartzite, dolomite or the like. To be used. In this case it is obvious that the dust that is unavoidable during the crushing process. Using flour as a filler to use and thereby achieve an equivalent mass. Incoming However, experiments have shown that the use of powdered or powdered quartzite acts as a filler harmful and disadvantageous, because it has been shown that the Dusty or flour-like quartzite with the alkalis of the binding agent become one strong flux combined and the burning of the molding compound caused. In the Technique, this phenomenon is commonly referred to as plaster formation.
