Description
Verfahren zur Herstellung von Kunst- und Werksteinen aus geschmolzener Schlacke. Es ist bekannt, geschmolzene Feuerungsrückstände aller Art zu Pflaster- oder ähnlichen Steinen zu gießen, wobei zur Formgebung Formen verwendet werden, die aus Eisen, Ton oder Sand hergestellt sind.Process for the production of artificial and work stones from molten Slag. It is known to use molten combustion residues of all kinds to pavement or similar stones, whereby molds are used for shaping, made of iron, clay or sand.
Dabei wird aber, weil es sich um ein schnell erkaltendes Schmelzerzeugnis handelt, entweder sehr viel Umlaufschlacke benötigt, oder es erfolgt eine Temperung-unter Aufwendung von Brennstoffen in besonderen Ofen.However, because it is a melted product that cools quickly is, either a lot of circulating slag is required, or there is a tempering-under Expenditure of fuel in special furnace.
.Nach der Erfindung wird die fließende, glühende Schlackenmasse in aus feinem Müll oder feiner Asche hergestellte Formen gegossen.According to the invention, the flowing, glowing slag mass is in Cast molds made from fine garbage or fine ash.
Das Formen erfolgt genau wie beim Formen .in Sand mittels Formkästen und Modellen; nur wird an Stelle des Sandes oder Tones feine Asche oder Feinmüll verwendet.The molding is done in the same way as molding in sand using molding boxes and models; only, instead of sand or clay, there is fine ash or fine refuse used.
Die aus diesen Stoffen hergestellten Formen haben die Eigenschaft, die geschmolzenen Massen vollkommen zu isolieren, wodurch eine Temperung erzielt wird; es bedarf also weder der Umlaufschlacke, noch besonderer Heizvorrichtungen oder Baustoffe, die gesamte Abstichschlacke kann gegossen und damit nutzbar verwendet werden.The forms made from these materials have the property to isolate the molten masses completely, whereby a tempering is achieved will; So neither the circulating slag nor special heating devices are required or building materials, all of the tapping slag can be poured and used in a usable manner will.
Abgesehen von diesen wirtschaftlichen Vorteilen, erhalten auch die so erzeugten Steine durch die gleichmäßige Temperung ein besseres Gefüge. Die bei Eisenformen sich bildenden Eisensulfide werden vermieden, verzierte oder profilierte Steine lassen sich leichter herstellen. Um den Steinen eine rauhe Außenfläche zu geben, können folgende Mittel angewendet werden i. Die Form wird nach Belieben rauh gestaltet.Aside from these economic benefits, the In this way, stones created a better structure due to the uniform tempering. The at Iron forms forming iron sulfides are avoided, decorated or profiled Stones are easier to make. To give the stones a rough outer surface the following means can be used: i. The shape will be rough at will designed.
a. Die Formwandungen werden mit kleinen kohlensauren Kalkstückchen versehen, die durch die Berührung mit der heißen Schlacke Kohlensäure abgeben, wodurch Gasblasen in die Steinoberfläche übergehen.a. The mold walls are made with small pieces of carbonate of lime provided, which release carbonic acid when they come into contact with the hot slag, whereby Gas bubbles pass into the stone surface.
3. Die Formwandungen werden vor dem Einlassen der heißen Schlacke mit Wasser bespritzt, wobei der sich beim Einfließen der heißen Schlacke bildende Wasserdampf Unebenheiten auf der Steinoberfläche erzeugt.3. The mold walls are before the hot slag is let in splashed with water, which forms when the hot slag flows in Water vapor creates bumps on the stone surface.
Will man die ganze Steinmasse porös gestalten, so werden in die flüssige Schlackenmasse vordem Eingießen in die Formen kleine kohlensaure Kalkstückchen oder wasserhaltige, feine Asche bzw. Müll eingebracht.If one wants to make the whole stone mass porous, then it becomes liquid Slag mass before pouring into the molds small carbonated lime pieces or water-containing, fine ash or garbage introduced.
Bei diesen Zusätzen wird nicht eine chemische Veränderung der Schmelzmasse bezweckt, wie dies durch Zusätze von Kalk, Ton oder Sand in bekannter Weise erreicht werden soll, sondern es soll lediglich eine Änderung des Steingefüges erzielt werden.With these additives there is no chemical change in the enamel mass aims how this is achieved in a known manner by adding lime, clay or sand should be, but only a change in the stone structure should be achieved.
