Description
Verfahren zur Herstellung von Bau- und Pflastersteinen aus Kupferschlacke Die Erfindung betrifft ein Verfahren zur Behandlung von Kupferschlacke, bei welchem es sich darum handelt, durch Vergießen der bei der hüttenmännischen Gewinnung von Kupfer anfallenden Schlacke in -Formen einen Ersatz für Ziegel oder Steine herzustellen.Process for the production of building blocks and paving stones from copper slag The invention relates to a method for treating copper slag, in which it is a matter of shedding the in the metallurgical extraction of Copper-accumulating slag in -forms to produce a substitute for bricks or stones.
Die Erfindung beruht auf der neuen Erkenntnis, daß ein besonderes Verfahren bei der Abkühlung dieser gewonnenen Schlacke die Beschaffenheit der zu gewinnenden Erzeugnisse in günstiger Weise beeinflußt, indem es diese außerordentlich hart macht, ihnen metallischen Glanz und ein gutes Aussehen verleiht.The invention is based on the new knowledge that a special Process in the cooling of this extracted slag the nature of the too in a beneficial way, by making them extraordinarily hardens, gives them a metallic sheen and good looks.
Gemäß der Erfindung wird die Schlacke, nachdem sie in Formen vergossen worden ist, in diesen zunächst auf Rotglut abgekühlt; hierauf werden die Formstücke aus der Form entfernt und mit einem Gemisch aus Schwefelpulver, Glimmer, Eisenpulver und Kleie, beispielsweise Reiskleie, bestreut, worauf sie in eine die Wärme schlecht leitende Masse, beispielsweise Strohasche, eingebettet und weiter abgekühlt werden. Da Strohasche ein sehr schlechter Wärmeleiter ist, geht die Abkühlung nur sehr langsam vor sich, so daß ein:Zerfallen oder Rissigwerden der Formlinge durch zu schnelle Abkühlung verhindert wird.According to the invention, the slag is after being poured into molds has been cooled down in these first to red heat; then the fittings removed from the mold and with a mixture of sulfur powder, mica, iron powder and bran, such as rice bran, sprinkled on them, whereupon they turn into a bad heat conductive mass, for example straw ash, embedded and further cooled. Since straw ash is a very poor conductor of heat, cooling is very slow in front of you, so that a: disintegration or cracking of the moldings by too fast Cooling is prevented.
Das Gemisch des obenerwähnten Streupulvers besteht zweckmäßig aus gleichen Teilen der einzelnen Bestandteile.The mixture of the above-mentioned scattering powder expediently consists of equal parts of the individual components.
