Description

Verfahren zum Einbinden von Feinerzen, Kiesabbränden u. dgl. unter Ausnutzung der Eigenwärme flüssiger Schlacke. Die Erfindung betrifft ein Verfahren zum Einbinden von Feinerzen, Kiesabbränden o. dgl. unter Ausnutzung der Eigenwärme flüssiger Schlacke.Process for incorporating fine ores, gravel burns and the like under Utilization of the inherent heat of liquid slag. The invention relates to a method for the integration of fine ores, gravel burns or the like, utilizing the inherent heat liquid slag.

Es sind bereits verschiedentlich Vorschläge gemacht worden, flüssige Schlacken zum Einbinden von Eisenerzen heranzuziehen. Bekanntlich ist man aber mit der Zugabe von Feinerzen o. dgl. sehr beschränkt, weil schon durch geringe Mengen der Schlacke soviel Wärme entzogen wird, daß sie dabei erstarrt.Various proposals have already been made, liquid ones Use slag to bind iron ores. As is well known, one is with the addition of fine ores or the like is very limited, because even small amounts so much heat is extracted from the slag that it solidifies in the process.

Um diesen Mangel zu beseitigen, hat man die Feinerze nicht in Schlackenkübeln, sondern in Ofen zugesetzt, die mit Gas oder auf andere Weise beheizt werden. Die Zusätze werden in diesen Ofen hoch erhitzt oder geschmolzen, gegebenenfalls nach Beifügung eines Flußmittels, und die Schlacke aus dem Hochofen oder Konverter läuft in die heißen Oxyde hinein.To remedy this deficiency, one does not have the fine ores in cinder buckets, but added to ovens that are heated with gas or in some other way. the Additives are heated or melted in this furnace, if necessary after Add a flux and the slag runs out of the furnace or converter into the hot oxides.

Dieses Verfahren ist jedoch unwirtschaftlich; denn es erfordert eine umständliche und kostspielige Anlage.However, this method is uneconomical; because it requires one cumbersome and expensive system.

Die Erfindung unterscheidet sich von den bekannten Verfahren dadurch, daß außer den Erzen ein Brennstoff, z. B. Koks, in die Schlacke eingeführt wird.The invention differs from the known methods in that that in addition to the ores, a fuel, e.g. B. coke is introduced into the slag.

Auf diese Weise gelingt es in einfachster Weise, die Schlacke genügend lange -flüssig zu erhalten, um erhebliche Mengen von Erzen oder Oxyden einzubinden.In this way it is possible in the simplest way to get enough slag to be kept liquid for a long time in order to bind significant quantities of ores or oxides.

Man kann auf diese Weise bei Verwendung von flüssiger Ferromanganschlacke so viel Erz zusetzen, daß das entstehende Produkt etwa 35 bis 40 Prozent Eisen und 5 bis io Prozent Mangan enthält.One can do this in this way when using liquid ferro-manganese slag add so much ore that the resulting product is about 35 to 40 percent iron and Contains 5 to 10 percent manganese.

Dieses fast selbstgehende, nicht staubende und hochwertigem Eisenerz gleichwertige Erzeugnis wird nach dem Erkalten beispielsweise durch einen Löffelbagger in Stückform gebracht und der Beschickung des Ofens zugesetzt.This almost self-propelled, non-dusting and high-quality iron ore Equivalent product is made after cooling, for example by a backhoe cut into bars and added to the furnace charge.

Bei Anwendung von Kiesabbränden lassen sich Blei, Arsen, Zink und Schwefel in Form von Sauerstoffverbindungen entfernen, deren wirtschaftliche Verwertung in bekannter Weise erfolgen kann.When using gravel burns, lead, arsenic, zinc and Remove sulfur in the form of oxygen compounds, their economic utilization can be done in a known manner.
