  Verfahren zur Herstellung von hochwertigem   Tiegelstabl.   



   Das bisherige Verfahren der Tiegelstahlherstellung ergibt vorzügliche Stähle, aber nur unter Verwendung entsprechend hochwertiger Ausgangsstoffe. Es wurde auch bereits vorgeschlagen, die Tiegel mit gegebenenfalls brikettiertem Eisenschwamm zu beschicken. 



   Demgegenüber ermöglicht die Erfindung, hochwertige Tiegelstähle aus verhältnismässig gering- 
 EMI1.1 
 da bei Verwendung von Eisenschwamm zu diesem Zweck der Tiegel springt, während er bei Verwendung dieses besonderen Eisens keine Spränge aufweist. In diesem Eisen sind mehr oder weniger erdige oder mineralische Beimengungen vorhanden. Bei Ausführung des Verfahrens wird daher vorteilhaft die möglichst vollständige Abscheidung der Gangart und des Oxydes von dem metallischen Eisen durch mechanische Reinigung herbeigeführt. 



   Durch diese Abscheidung der Gangart und der Oxyde aus dem metallischen Eisen wird die Bildung von Schlacke vermieden, welche die Tiegel zerstört. Durch das Brikettieren des metallischen Eisens wird das Bersten der Tiegel verhütet, das sich unweigerlich bei Verwendung pulveriger bzw. feinverteilter Beschickung zeigt. 



   PATENT-ANSPRÜCHE :

 in fester Form gewonnenem Eisen als Einsatzmaterial, dadurch gekennzeichnet, dass als solches nach dem Patent Nr. 109149 hergestelltes Eisen verwendet wird.

  Process for the production of high quality crucible bars.



   The previous process of crucible steel production results in excellent steels, but only with the use of correspondingly high-quality raw materials. It has also already been proposed to load the crucibles with optionally briquetted sponge iron.



   In contrast, the invention makes it possible to produce high-quality crucible steels from relatively low
 EMI1.1
 because the crucible cracks when using sponge iron for this purpose, while it has no cracks when using this special iron. In this iron there are more or less earthy or mineral additions. When the method is carried out, the most complete possible separation of gangue and oxide from the metallic iron is therefore advantageously brought about by mechanical cleaning.



   This separation of gangue and oxides from the metallic iron prevents the formation of slag, which destroys the crucible. Briquetting the metallic iron prevents the crucible from bursting, which inevitably occurs when using powdery or finely divided loading.



   PATENT CLAIMS:
 EMI1.2
 Iron obtained in solid form as feed material, characterized in that iron produced as such according to patent no. 109149 is used.
