  Verfahren zur Herstellung von Stahl. 



   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. Der   Hilfsschmelzraum,   welcher eine geeignete feuerfeste Aus-   kreidung   besitzt, ist nicht bestimmt, selbst einen Teil des   elektrischen     Stromkreises zu   bilden, jedoch kann ein solcher von geeigneter Art in jedem gewünschten Zeitpunkt ill denselben eingeleitet worden.

   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-

     Dieses Verfahren gestattet   auch die   Umformung   von   gewöhnlichem Gusseisen   in Stahl und dient hiezu vorzugsweise der in Fig. 2 dargestellte Kupolofen f mit Vorherd y und in dessen Inhalt   einsenkbaron   Elektroden e, e. 



   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

 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

     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.
