Description

Gegenstände aus: spezifisch schwerer Schmelzmasse Zusatz. zum Zusatzpatent, 697653 Die Erfindung betrifft Gegenstände aus spezifisch schwerer Schmelzmasse, gegebenenfalls unter Zusatz von Fluß- und Färbemittehl und Naturgesteinen, wie Basalt o: dgl. Eruptivgesteinen, nach Patent 697 653, Zusatz zu Patent 689 030. .Objects made of: specifically heavy enamel additive. to the additional patent, 697653 The invention relates to objects made of specifically heavy enamel, optionally with the addition of fluids and coloring agents and natural rocks such as basalt o: Similar igneous rocks, according to patent 697 653, addition to patent 689 030..

Letzteres betrifft Gegenstände aus spezifisch - schwerer Schmelzmasse; die aus Schwerspat oder Witherit und gegebenenfalls Sehlacken, Flüß- - und Färbemitteln berge: stellt sind.The latter concerns objects made of specifically heavy enamel; those made from barite or withitherite and, if necessary, optical varnishes, liquids and dyes mountains: are.

Die Notwendigkeit, Metalle aus Gründen der Ersparnis für Belastungszwecke auszusehalten, führte neben anderen Ersatzstoff zur Entwicklung des Schwersteingusses (Bärytguß), der auf GrLUrd seines hohen spezifischen Gewichts und. seiner guten Festigkeitswexte sowie seiner höheren Korrosions-und Abriebfestigkeit als die der zu verdrängenden Metallwerkstoffe als vollwertiger Austauschwerkstoff bezeichnet werden kann. Das Zusatzpatent 697 653 :brachte weitere Verbesserung der Festigkeit, Dichte und Abriebfestigkeit durch-Zuschlag von Naturgesteinen eruptiver Entstehung-Es wurde nun gefunden, daß eine weitere Verbesserung der Eigenschaften des Barytgusses nachdem Hauptpatent und dem vor. genannten Zusatzpatent durch Zuschlag. von Eisenerzen oder einem geringen Anteil (etwa 5 bis i o %) Eisen in Form von Abfalleisen, Gußspänen, Hammerschlag u. ä. oder eines Gemisches beider zusammen zu Schwerspat oder Witherit erzielt wird. Es tritt bei diesen Zuschlägen eine weitgehende Verdünnung des Schmelzflusses, .eine schnellere Be, endigung des Garungsprozesses und eine Gefügeverdichtung ein. Die metallurgischen Vorgänge sind noch nicht vollkommen geklärt, es scheint jedoch, daß der Anteil an Eisen als Element oder Oxyd eine Art Katalyt -darstellt, der eine raschere Umsetzung des Schmelzflusses bewirkt. So wird z. B. die Schmelzdauer einer Charge nahezu um die Hälfte verkürzt.The need to use metals for the sake of saving for encumbrance purposes Enduring it led, among other substitutes, to the development of heavy stone casting (Bärytguß), which is due to its high specific weight and. its good Strength and its higher resistance to corrosion and abrasion than that of the Metal materials to be displaced are referred to as fully-fledged replacement materials can be. The additional patent 697 653: brought further improvements in strength, Density and abrasion resistance through the addition of natural rocks eruptive formation it has now been found that a further improvement in the properties of the barite cast after main patent and before. named additional patent by surcharge. of iron ores or a small proportion (about 5 to 10%) of iron in the form of scrap iron, Casting chips, hammer blows, etc. or a mixture of both together to form barite or witherit is achieved. These additions are largely diluted the melt flow, a faster end of the cooking process and a Structural compaction. The metallurgical processes have not yet been fully clarified, it appears, however, that the proportion of iron as an element or oxide is a kind of catalytic - represents, which causes a faster conversion of the melt flow. So z. B. the melting time of a batch is reduced by almost half.

Weitere Vorteile der Anwendung dieser Zuschläge liegen in dem geringeren Wärmeaufwand je Einheit Barytguß bei gleichen, Ergebnissen hinsichtlich der Eigenschaften der Schmelzmasse. Es ist bereits bekannt, mineralisch Schmelzmassen, Eisen oder Eisenverbindungen insbesondere zur Verbesserung der Festigkeitseigenschaften der aus den Massen erzeugten Gegenstände zuzusetzen. Die Anwendung eines Zuschlags von Eisen o. dgl, bringt im vorliegenden Fall noch weitere zusätzliche wesentliche Vorteile, wie im Vorangegangenen bereits angegeben.Further advantages of using these supplements are that they are lower Heat consumption per unit of barite cast with the same results in terms of properties the enamel. It is already known, mineral enamel, iron or Iron compounds in particular to improve the strength properties of the to add objects produced from the masses. The application of a surcharge of Iron o. The like, brings in the present case further additional essential advantages, as already stated above.
