  Verfahren zur Herstellung legierter Stähle 
 EMI1.1 
 eine Legierung erschmolzen wird, die nach Mischung mit dem gleichzeitig erschmolzenen Siemens-Martin-Stahl, der unlegiert oder auch schwach legiert sein kann, die gewünschte Zusammensetzung ergibt. Im Elektroofen kann entweder mit höher legiertem Schrott oder auch mit Zusätzen von Legierungsmetallen gearbeitet werden. 



   Man kann nun entweder so verfahren, dass zur Entschwefelung und Desoxydation beide Stähle zusammengegossen und mit einer hoch reaktionsfähigen Schlacke innigst durchwirbelt werden oder dass die Schlacke zunächst nur mit einem der beiden Stähle und erst anschliessend durch Hinzugiessen des andern Stahles auch mit diesem reagiert. 



   Das Zusammengiessen der beiden Stähle und der Schlacke kann sowohl in einer Pfanne als auch in einem Ofen geschehen.

  Process for the production of alloyed steels
 EMI1.1
 an alloy is melted, which after mixing with the simultaneously melted Siemens-Martin steel, which can be unalloyed or weakly alloyed, gives the desired composition. In the electric furnace you can either work with higher-alloyed scrap or with additions of alloy metals.



   One can now proceed either in such a way that both steels are cast together for desulphurisation and deoxidation and whirled through with a highly reactive slag or that the slag initially only reacts with one of the two steels and only then reacts with the other steel by adding it.



   The two steels and the slag can be poured together in a pan or in an oven.

PATENTANSPRUCH : Verfahren zur Herstellung legierter Stähle mit Hilfe des Schlackenreaktionsverfahrens, dadurch gekennzeichnet, dass in einem Elektroofen ein legierter Stahl erschmolzen wird, dessen Zusammensetzung so gewählt ist, dass sich nach Mischung mit einem gleichzeitig in einem Siemens-Martin-Ofen erschmolzenen unlegierten oder schwach legierten Stahl die gewünschte Zusammensetzung ergibt, und dass zur Entschwefelung und Desoxydation entweder beide Stähle zusammengegossen und mit einer hoch reaktionsfähigen Schlacke innigst durchwirbelt werden oder dass die Schlacke zunächst nur mit einem der beiden Stähle und erst anschliessend durch Hinzugiessen des andern Stahles auch mit diesem reagiert. **WARNUNG** Ende CLMS Feld Kannt Anfang DESC uberlappen**. PATENT CLAIM: Process for the production of alloyed steels with the help of the slag reaction process, characterized in that an alloyed steel is melted in an electric furnace, the composition of which is selected so that after mixing with an unalloyed or weakly alloyed steel melted at the same time in a Siemens-Martin furnace, the results in the desired composition, and that for desulphurization and deoxidation either both steels are cast together and whirled through with a highly reactive slag or that the slag initially only reacts with one of the two steels and only then reacts with this when the other steel is poured in. ** WARNING ** End of CLMS field may overlap beginning of DESC **.
