Die Anwendung von elektrischen Frischherden behufs Feinens des in einem Ofen gewonnenen Metalles ist in der Metallurgie bekannt ; demgegenüber betrifft vorliegende Ernndung jedoch die Anwendung eines beweglichen elektrischen Hilfsschmelzraumes, welcher die verschiedenen Öfen entnommenen, also auch verschiedene Zusammensetzung aufweisenden

Auf umstehender Zeichnung sind Ausführungsbcispiele der Anwendung des neuen Verfahrens veranschaulicht.

Diee Einrichtung wird insbesonders dann sehr vorteilhaft sein, weunn eine Batterie elektrischer Schmelzöfen vorltauden ist, deren Fassungsraum geringer ist, als derjenige von Hochöfen und anderen in der Metallurgie gewöhnlich benutzten Schmelzvorrichtungen.
Nach jedem Abstich oder einer Reihe von Abstichen wird der geschmolzene Inhalt des Hilfsschmelzraumes in einen Strom eingeschaltet (z. B. durch Einsenken der Elektroden e, e, Fig. 1), wobei durch das Durchleiten des elektrischen Stromes geeigneter Stärke und Spannung eine Widorerhitzullg der Schmelzmasse in regelbarer Weise erfolgen kann :

Auf diese Weise kann man beispielsweise Stahl aus in Kupolöfen umgeschmolzenem Gusseisen herstellen, indem man dasselbe durch Zusatz von Oxyden reinigt, also an hohlen- stoff ' irmer macht und ähnlich wie mittelst eines i\1artinofens wird man auch eine Ent-

Das vorliegende Verfahren ist auch aus dem Grunde sehr vorteilhaft, weil es infolge der grossen Leichtigkeit der Entnahme von Proben des geschmolzenen Metalles, dessen Oberfläche in der Giesspfanne sehr leicht zugänglich ist, das Überwachen des Vorganges wesentlich erleichtert.

Process for the production of steel.
The use of fresh electric cookers to refine the metal obtained in a furnace is known in metallurgy; on the other hand, however, the present invention relates to the use of a movable electrical auxiliary melting chamber from which the various furnaces are removed, i.e. also have different compositions
EMI1.1
setting transformed.
Exemplary embodiments of the application of the new method are illustrated in the drawing below. The auxiliary smelter, which has a suitable refractory lining, is not intended to form part of the electrical circuit itself, but such a furnace of a suitable type can be initiated at any desired point in time.
EMI1.2
Openings of the individual fusible joints can be brought to a lively construction of a battery.
This device will be particularly advantageous when there is a battery of electric smelting furnaces, the capacity of which is less than that of blast furnaces and other smelting devices commonly used in metallurgy.
After each tapping or a series of tapping, the molten content of the auxiliary melting chamber is turned on into a current (e.g. by lowering the electrodes e, e, Fig. 1), whereby the passage of an electric current of suitable strength and voltage results in a resistance to heat Melt mass can be done in a controllable way:

to get.
In this way, for example, steel can be made from cast iron remelted in cupola furnaces by purifying it by adding oxides, that is to say, reducing the amount of carbon, and similarly to using a furnace, one will also
EMI1.4
This process also allows ordinary cast iron to be formed into steel and is preferably used for this purpose in the cupola furnace f shown in FIG. 2 with forehearth y and electrodes e, e which can be lowered into its contents.
The present method is also very advantageous for the reason that, due to the great ease of taking samples of the molten metal, the surface of which is very easily accessible in the pouring ladle, it makes monitoring the process much easier.
