 hüllung wird der Kohlenstoff gegen eine unmittelbare Verbrennung geschützt, wenn er mit dem geschmolzenen Metall in Berührung kommt.

   Die Umhüllung soll daher genügend Widerstand bieten, um den Kohlenstoff so lange zu schützen, bis der Stahl während des Einfliessens in die   Giesspfanne gewissermassen   ein Umrühren herbeiführt und dadurch den Kohlenstoff mit der Metallmasse in innige Berührung bringt. Nur auf diese Weise können Verluste an   kohlenstoff   vermieden und infolgedessen eine regelmässige Kohlenstoffzuführung sowie ein homogenes Material erzielt werden. Die Säcke oder Umhüllungen für den Kohlenstoff können beispielsweise aus Leinwand, starkem Papier, Holz oder dgL bestehen. 



   Das vorstehend beschriebene Verfahren zeichnet sich gegenüber allen bisher bekannten Verfahren dadurch aus, dass durch die Vereinigung der beiden genannten Operationen die Erzielung eines Stahles von bestimmter Güte und Eigenschaften ermöglicht ist. Ferner stellt sich das Verfahren sehr ökonomisch, denn es wird bei demselben die Menge des zuzufügenden Spiegeleisens oder Ferromangans wesentlich verringert.

 shell, the carbon is protected from immediate combustion if it comes into contact with the molten metal.

   The envelope should therefore offer sufficient resistance to protect the carbon until the steel, as it flows into the pouring ladle, causes a certain degree of stirring and thereby brings the carbon into intimate contact with the metal mass. Only in this way can carbon losses be avoided and, as a result, a regular carbon supply and a homogeneous material can be achieved. The bags or wrappings for the carbon can for example consist of canvas, strong paper, wood or similar.



   The method described above is distinguished from all previously known methods in that the combination of the two operations mentioned enables the achievement of a steel of certain quality and properties. Furthermore, the process is very economical, because the amount of fried iron or ferro-manganese to be added is significantly reduced.

PATENT-ANSPRUCH : Verfahren zur Erzeugung von Stahl nach Methoden, bei denen das Prinzip der Rückkehlung Anwendung findet, dadurch gekennzeichnet, dass zwei ihrem Wesen nach bekannte Massnahmen in der Art vereinigt werden, dass zunächst die Schlacken durch Zugabe von Flussmitteln, wie Cblornatrium oder einem Gemisch aus Natrium-und Kaliumsalzen in dem Ofen oder Konverter dünnflüssig gemacht werden und unmittelbar darauf die Rückkohlung des Metallbades in der Giesspfanne unter Verwendung eines Anthrazits (Carmoya) mit zweck- EMI2.2 eingeworfen wird, um allen Kohlenstoff der flüssigen Masse einzuverleiben und dadurch ein gleichmässiges Metall von gewünschter Zusammensetzung zu erhalten. PATENT CLAIM: Process for the production of steel according to methods in which the principle of recessing is used, characterized in that two measures known by their nature are combined in such a way that the slag is first removed by adding fluxes such as carbon sodium or a mixture of sodium and potassium salts are made thin in the furnace or converter and immediately afterwards the carbonization of the metal bath in the ladle using an anthracite (Carmoya) with EMI2.2 is thrown in to incorporate all the carbon in the liquid mass and thereby obtain a uniform metal of the desired composition.
