Description

Verfahren zur Herstellung von Steinen aus Hochofenschlacke. Zusatz zum Patent 422386. Bei dem Verfahren nach dem Hauptpatent findet gegenüber den üblichen Verfahren eine solche Verminderung des Abfalls und damit eine Verwertung der gesamten zur Schmelzung der Schlacke aufgewendeten Wärme statt, daß für den Hochofenbetrieb andere Stoffe als bisher verwendet werden können, die nützliche Schlackenbestandteile ergeben.Process for the production of stones from blast furnace slag. Addition to patent 422386. In the process according to the main patent, there is such a reduction in the waste compared to the usual processes and thus a utilization of the entire heat expended to melt the slag that other substances than before can be used for the blast furnace operation, the useful slag constituents result.

ach der vorliegenden Erfindung soll der Charge des Hochofens Basalt zweckmäßig nach Anreicherung des Eisengehaltes zugesetzt werden. Es gibt Basalte, welche bis io Prozent Eisen, und zwar in Form von Magneteisenstein enthalten, deren Verhüttung bisher wegen ihres geringen Eisengehaltes unwirtschaftlich war. Kann aber der gesamte Basaltgehalt nach dem- Verfahren :des Hauptpatentes zur Herstellung von Steinen ohne den früher üblichen Abfall benutzt werden, so ist die zur Schmelzung desselben aufgewendete Wärme nicht verloren. Zweckmäßig ist es, wenn diese Basalte zerkleinert und einem elektromagnetischen Scheideverfahren ausgesetzt werden. Durch dieses Verfahren wird ein an Eisen wesentlich angereichertes Erzeugnis gewonnen, welches der Hochofenbes#-hickung zugegeben werden kann. Es wird dann eine basalthaltige Schlacke entstehen, die ein noch verbesserter Rohstoff für die Herstellung von Plastersteinen ist.According to the present invention, the batch of the blast furnace should be basalt are expediently added after the iron content has been enriched. There are basalts which contain up to 10 percent iron, namely in the form of magnetic iron stone, their Smelting was previously uneconomical because of its low iron content. Can but the entire basalt content according to the process: the main patent for production of stones are used without the waste customary in the past, it is for melting heat expended on the same is not lost. It is useful if these basalts crushed and subjected to an electromagnetic cutting process. By this process produces a product that is significantly enriched in iron, which can be added to the blast furnace heating. It then becomes a basalt one Slag is created, which is an even better raw material for the production of paving stones is.

Der von dein Eisen befreite zerkleinerte Basalt kann in bekannter Weise zur Herstellung von Betonplatten u. dgl. Verwendung finden. Es ist an sich bekannt, Basalt auf Steinmassen zu verschmelzen unter Gewinnung von Eisen.The crushed basalt freed from your iron can be used in known Way for the production of concrete slabs and the like. Use. It is in itself known to fuse basalt on stone masses with the extraction of iron.
