Description

Verfahren zur Herstellung von Produkten aus- Speckstein. Zur Herstellung von Specksteinartikeln wurde bisher nur Speckstein verwendet. Das als chinesischer Bildstein bekannte Material Agalmatolith kam für die Fabrikation von Steatitartikeln nicht in Frage.Process for the manufacture of products from soapstone. For the production So far only soapstone has been used of soapstone items. That as a Chinese one Bildstein's well-known material agalmatolite was used for the manufacture of steatite articles out of the question.

Durch ausgedehnte Versuche hat die Erfinderin ein Verfahren erfunden, das einmal die Verwendung des Agahnatoliths und weiter eine erhebliche Ersparnis an Kohle, Arbeit und Zeit herbeiführt. Diese Vorteile entstehen bei der Fabrikation aller Steatiterzeügnisse, sei es aus Speckstein (Steatit) oder aus Agalmatolith oder aus einer Mischung beider Rohstoffe.Through extensive experiments, the inventor has invented a process Firstly the use of Agahnatolite and furthermore a considerable saving brings about coal, labor and time. These advantages arise during manufacture of all steatite products, be it from soapstone (steatite) or from agalmatolite or from a mixture of both raw materials.

Die bisherige Herstellungsweise für Steatitfabrikate verlangte nach der Formung (meist Pressem:) zwei Brände: Einmal den Schrühbrand bei etwa 1¢50° meist im Rundofen bei einer Brennzeit von etwa a¢ Stunden und dann. den Glasurbrand bei einer Temperatur von goo bis iooo° meist in der Muffel.The previous production method for steatite products demanded Forming (mostly press) two firings: once the biscuit firing at about 1 ¢ 50 ° mostly in a round furnace with a burning time of about a ¢ hours and then. the glaze firing at a temperature of goo to iooo ° mostly in the muffle.

Der Zusatz von Flußmitteln hat sich bisher wenig oder gar nicht bewährt, es kam höchstens Feldspat in Frage.The addition of flux has so far proven little or no benefit, at most feldspar came into question.

Die Beigabe anderer Flußmittel wurde von namhaften Fachleuten abgelehnt mit der Be-. gründung, daß die Anwesenheit von Mg0, das zu etwa 32 bis 3¢ Prozent im Speckstein enthalten ist, diese Beigaben nicht gestatte. Es ist der Erfinderin gelungen, in einem Verfahren durch Zusatz verschiedener Flußmittel, wie Natriumhydroxyd, Salzen. der Alkalimetalle, wasserlöslicher Fluoride, bessere Schmelz- und Sinterungsverhältnisse zu erzielen und die Verwendbarkeit des Agalmatoliths zu ermöglichen.The addition of other fluxes was rejected by well-known experts with the loading. reason that the presence of Mg0, which is about 32 to 3 ¢ percent in soapstone, does not allow these additives. The inventor succeeded in a process by adding various fluxes, such as sodium hydroxide, salts. of alkali metals, water-soluble fluorides, to achieve better melting and sintering conditions and to enable the usability of the agalmatolite.

Der wesentliche Erfolg der Erfindung besteht darin, daß die fertiggeformten Steatitkörper nicht mehr in Kapseln gelegt und im Rundofen bei 145o° in etwa 24stündigem Brand vorgebrannt werden.The main success of the invention is that the finished formed Steatite bodies no longer placed in capsules and put in a round oven at 145o ° for about 24 hours Fire to be pre-burned.

Nach der Erfindung wird der Versatz aus Steatit oder Agalmatolith mit den obengenannten Flußmitteln hergestellt und der geformte Körper nur einem Brande von goo bis iooo° während z bis 5 Stunden (je nach Größe und Versatz) unterworfen; dabei ist ein Einlegen in Kapseln überflüssig.According to the invention, the batch is made of steatite or agalmatolite made with the above fluxes and the molded body only one Subject to fire from goo to 100o ° for z to 5 hours (depending on size and offset); There is no need to put them in capsules.
