Description
Verfahren zur Herstellung eines Mörtelstoffes aus Hochofenschlacke. Es ist vorgeschlagen worden, ausschließlich aus Hochofenschlacke Zement herzustellen, unter Aufschließen des in der Schlacke enthaltenen. Kalkes durch Erhitzen. Die Erfindung betrifft eine neue Ausführungsform des Verfahrens, bei welchem die auf der Halde lagernden Schlacken verarbeitet werden.Process for the production of a mortar from blast furnace slag. It has been proposed to produce cement exclusively from blast furnace slag, with digestion of the contained in the slag. Lime by heating. The invention relates to a new embodiment of the method in which the on the dump stored slag are processed.
Nach der Erfindung werden diese Schlakken mit Hilfe von frischer, flüssiger Schlacke geglüht. Das kann .beispielsweise dadurch geschehen, daß man die Schlacken auf der Halde lockert und die Schlackenbrocken dann mit einer Schicht glühender Schlacke überdeckt oder aber auch durch Vermischen von alter und flüssiger Schlacke in einem; Kübel, in dem dann eine längere gegenseitige Beeinflussung stattfindet. Das Gemisch wird vor oder nach dem Erstarren aus dem Kübel gekippt und dann vermahlen.According to the invention, these slugs are made with the help of fresh, Annealed liquid slag. This can happen, for example, by the cinder on the heap loosens and then the cinder lumps with a layer glowing slag covered or by mixing old and liquid Slag in one; Bucket, in which a longer mutual influence then takes place. Before or after solidification, the mixture is tipped out of the bucket and then ground.
Bei diesem Verfahren ergeben sich mehrere für die praktische Einführung der Herstellung von Mörtel aus Schlacken wesentliche Vorteile. Die lästigen Schlackenhalden, die kostbare Flächen bedecken und Kosten verursachen, können beseitigt und nutzbar gemacht werden. Da die auf den Halden lagernden Schlacken den verschiedensten Abstichen entstammen, so ergibt sich bei der Verarbeitung ohne weiteres ein Gemisch verschiedener Schlackensorten, das zur Erzielung eines guten Erzeugnisses erforderlich ist. Das Aufschließen des in der Haldenschlacke enthaltenen Kalkes wird durch das intensive, lange Zeit anhaltende Glühen in bester Weise durchgeführt und erfordert trotzdem keinerlei Kosten. Endlich kann das Verfahren abseits vom Hochofen durchgeführt werden, was für den Dauerbetrieb notwendig ist, da der eigentliche Hochofenbetrieb durch die Herstellung eines Nebenerzeugnisses nicht gestört werden: darf.With this procedure there are several for the practical introduction the production of mortar from slag has significant advantages. The annoying slag heaps that cover valuable areas and generate costs, can be eliminated and made usable be made. Since the slag stored on the heaps has a wide variety of tapping originate, a mixture of different arises during processing Types of slag required to obtain a good product. That The lime contained in the heap slag is broken down by the intensive, long-lasting annealing performed in the best way and still requires no cost. Finally, the process can be carried out away from the blast furnace, which is necessary for continuous operation, since the actual blast furnace operation is through the production of a by-product is not disturbed: may.
Es ist schon vorgeschlagen worden, glühende Schlacke zum Trocknen von nassem Schlackensand zu benutzen und zu dem Zweck Sand und flüssige Schlacke in einer Schleudertrommel zusaxmnenzuführen. Man hat auch vorgeschlagen, die flüssige Schlacke mit Hilfe eines Strahles von Schlackensand zu zerkleinern. Diese Verfahren haben aber mit der Erfindung nichts gemein; denn bei ihnen findet kein Glühen des Schlackensandes durch eine längere Einwirkung der heißen Schlacke und somit auch keine Aufschließung des Schlackensandes statt. Nur dadurch, daß die alte Schlacke der längere Zeit andauernden Einwirkung sie umschließender flüssiger Schlacke ausgesetzt wird, kann ein Schlackengemisch erzielt werden, das nach dem Vermahlen ohne weiteres zur Herstellung von gutem Mörtel brauchbar ist.It has already been suggested to use red-hot slag to dry it to use wet cinder sand and for the purpose sand and liquid cinder to be brought together in a centrifugal drum. It has also been suggested that the liquid Crush slag with the help of a jet of slag sand. These procedures but have nothing in common with the invention; because with them there is no glow of the Slag sand due to a longer exposure to the hot slag and thus also no decomposition of the slag sand takes place. Only because the old slag exposed to long-term exposure to liquid slag surrounding them is, a slag mixture can be obtained, which after grinding easily is useful for making good mortar.
