Description

Verfahren zur Herstellung von porösen Gußstücken aus geschmolzenem Basaltsplitt u. dgl. Die Herstellung von Gußstücken aus geschmolzenem Basalt sowie das Porösmachen derselben durch Vermischen der geschmolzenen Masse mit feuchtem Sand; wobei sich Wasserdampf bildet und sich als Dampfperlen in die Schmelzmasse einlagert, ist bekannt. Es hat dieses Verfahren, Gußstücke porös zu machen, den Nachteil, daß bei einem sehr umständlichen Verfahren die Schmelzmasse bis etwa 1q.00° oder mehr erhitzt werden muß, um Dünnflüssigkeit zu erlangen. - Den Sand mit der Masse zu vermischen, hat wiederum den Nachteil, daß die fertigen Gußstücke durch den erhaltenen sehr hohen Hitzegrad sehr spröde werden, sich nicht werk:-mäßig bearbeiten lassen und eine unschöne, dunkle Farbe erhalten.Process for making porous castings from molten Basalt chippings and the like The manufacture of castings from molten basalt as well as making them porous by mixing the molten mass with the moist Sand; whereby water vapor is formed and as vapor pearls in the melt stores is known. It has this method of making castings porous Disadvantage that in a very cumbersome process the melt mass up to about 1q.00 ° or more must be heated to obtain thin liquid. - The sand with that Mixing mass, in turn, has the disadvantage that the finished castings through the very high degree of heat obtained become very brittle, do not work in a factory-like manner leave and get an unsightly, dark color.

Vorliegende Erfindung bezweckt, Basaltsplitt, Bäsaltstaub u. dgl. bei der Basaltindustrie sich ergebende minderwertige Abfallstoffe zu verschmelzen und Gußstücke für die Zwecke der Bauindustrie herzustellen, welchen obige schädliche Eigenschaften nicht anhaften.The present invention aims to remove basalt chippings, basalt dust and the like. to merge inferior waste materials resulting from the basalt industry and to manufacture castings for the purposes of the building industry, which of the above are harmful Properties do not adhere.

Das Verfahren besteht darin, daß das Schmelzmaterial nur bis zur Dickflüssigkeit, welche bei einem Hitzegrad von etwa iioo bis i2oo°, je nach Art des Materials, erreicht ist, und durch Eingießen in entsprechende Formen zu Werksteinen gestaltet wird. Es wird hierdurch erreicht, daß, ohne Bei-1 mischung von feuchtem Sand oder anderen Stoffen, nur durch die dem Schmelzmaterial anhaftende - Feuchtigkeit, aus welcher sich während des Schmelzens Dampfperlen bilden, und durch die zwischen demselben lagernde Luft; welche bei der Dickflüssigkeit - der Schmelzmasse und durch deren Dichtigkeit und Schwere nur sehr gering entweichen kann, sich Bläschen. in die Gußstücka einlagern und dieselben porös machen.The method consists in the fact that the melt material is only thickened to the extent that it is thick, which is reached at a heat level of about 100 to 1200 degrees, depending on the type of material, and is shaped into stone by pouring it into appropriate molds. It is hereby achieved that, without examples 1 mixture of moist sand and other materials, only by adhering to the melt material - moisture, from which form during the melting vapor beads, and the overlapping between the same air; which with the thick liquid - the molten mass and due to its tightness and weight can only escape very little, are vesicles. store in the casting and make it porous.

Nach vorliegendem Verfahren hergestellte Gußstücke erhalten infolge der angewendeten verhältnismäßig geringen Hitze und durch ihre Porösität bei einer schön grau bis graublauen Farbe eine solche Zähigkeit, daß sie sich mit Hammer und Meißel bearbeiten lassen, was für die Verwertung von großer Wichtigkeit ist; auch können sie im Baugewerbe an Stelle von Basaltlava, womit das Material große Ähnlichkeit hat, mit gutem Erfolg verwendet werden.Castings produced by the present process are obtained as a result the relatively low heat used and due to its porosity at a beautiful gray to gray-blue color such toughness that it can be smeared with a hammer and Have chisels processed, which is of great importance for recovery; even They can be used in the construction industry instead of basalt lava, with which the material is very similar has to be used with good success.
