Description

Verfahren zur Herstellung von synthetischem Roheisen Es ist bekannt, -daß man bei der Herstellung von synthetischem Roheisen mit dem diskontinuierlichen Verfahren praktisch nur Kohlenstoffgehalte bis zu etwa z,7% Herreichen kann. Die Kohlung auf höhere Gehalte erfordert besondere Maßnahmen, die die Arbeitsweise umständlich und teuer machen. Es hat sich daher die Ansicht herausgebildet, daß für die Herstellung eines Roheisens mit 30/0 C und darüber die satzweise Beschickung, d. h. die Verwendung eines Stahlofens, nicht geeignet ist.Process for the production of synthetic pig iron It is known -that one in the production of synthetic pig iron with the discontinuous Process can reach practically only carbon contents up to about z, 7%. the Kohlung to higher levels requires special measures, which make the working method cumbersome and make it expensive. It has therefore developed the view that for the production a pig iron at 30/0 C and above the batch charging, d. H. the usage a steel furnace, is not suitable.

Es wurde nun überraschenderweise gefunden, daß unter Beachtung einer einfachen Maßnahme der Hochfrequenztiegelofen für die Erzeugung eines hochgekohlten Roheisens herangezogen werden kann. Zu diesem Zweck wird @erfindungsgemäß ein Teil des benötigten Kohlungsmittels, gegebenenfalls der überwiegende Anteil desselben, in einer zusiammenhängenden Schicht auf dem Boden des Tiegels !aufgegeben bzw. aufgestampft und darüber schichtweise der Schrott und der Rest des Kohlun,gsmittels @abwechselnd angeordnet. Auf diese Weise gelingt es, ein Roheisen 'mit einem Kohlenstoffgehalt bis etwa 4,50/0 mühelos zu erschmelzen. Als Kohlungsmittel kommen Koks, Pechkoks, Petrolkoks, Anthrazit usw. in Frage.It has now been found, surprisingly, that taking into account one simple measure of the high-frequency crucible furnace for the production of a high-carbon Pig iron can be used. For this purpose, according to the invention, @ becomes a part the required coaling agent, possibly the predominant part thereof, abandoned or tamped on in a coherent layer on the bottom of the crucible! and on top of it the scrap and the rest of the carbon in layers alternately arranged. In this way it is possible to create a pig iron with a carbon content to about 4.50 / 0 to melt effortlessly. Coke, pitch coke, Petroleum coke, anthracite, etc. in question.

Der Vorteil des vorgeschlagenen Verfahrens besteht darin, @daß bei, der Verwendung reiner Ausgangswerkstoffe ein sehr reines Roheisen hergestellt werden kann, da eine zusätzliche -Verunreinigung der Schmelze beim Hochfrequenzofen sicher vermieden wind. Ein reines hochgekohltes Roheisen ist für viele Zwecke der Technik erwünscht, heispiielsweise für die Herstellung von Eisenpulver für die Zwecke der Metallkeramik.The advantage of the proposed method is that @ that with, the use of pure raw materials a very pure pig iron can be produced can, as an additional contamination of the melt in the high-frequency furnace, is safe avoided wind. A pure high-carbon pig iron is for many Desired for technical purposes, for example for the production of iron powder for the purpose of metal ceramics.
