  Verfahren zur Behandlung heissgehender Chargen in der basischen Bessemerbirne. 



   In dem Stammpatente Nr.   3fi423   ist eine Erfindung beschrieben, die darin besteht, dass bei der Darstellung von Stahl nach dem   Thomasprozess   gegen Ende der Entkohlung oder während der Entphosphorung eine brikettierte Mischung von eisenoxydhaltigen Stoffen und gelöschtem Kalk dem Bade zugesetzt wird. Durch dieses Verfahren wird eine schnelle Verbrennung des Phosphors erzielt, während die Verbrennung des Eisens, der Abbrand,

 Phosphorgehalt. 



   Es hat sich nun   gezeigt, dass man einen Teil   der Eisenoxyde in der zuzusetzenden Mischung vorteilhaft durch Oxyde des Mangans ersetzen kann. Die Wirkung ist die, dass ein kleiner Teil der Manganoxyde durch den Phosphor des Eisenbades reduziert wird, 
 EMI1.2 
 



   Da die Schlacke hierdurch dünnflüssiger wird, so wird durch den Zusatz von Manganoxyden die Entphosphorung des Eisenbades noch weiter erleichtert. 



   Das Verfahren wird so ausgeführt, dass der in den   Konverter einzuführenden Mischung   \on Eiscnoxyden und Kalkhydrat oder einem andern geeigneten Bindemittel hochprozentige

  Process for the treatment of hot batches in the basic Bessemer pear.



   In the parent patent no. 3fi423 an invention is described which consists in adding a briquetted mixture of iron oxide-containing substances and slaked lime to the bath when steel is made after the Thomas process towards the end of decarburization or during dephosphorization. With this method, a quick combustion of the phosphorus is achieved, while the combustion of the iron, the burn-off,

 Phosphorus content.



   It has now been shown that some of the iron oxides in the mixture to be added can advantageously be replaced by oxides of manganese. The effect is that a small part of the manganese oxides is reduced by the phosphorus in the iron bath,
 EMI1.2
 



   Since the slag becomes thinner as a result, the dephosphorization of the iron bath is made even easier by the addition of manganese oxides.



   The process is carried out in such a way that the mixture of ice oxides and hydrated lime or another suitable binding agent to be introduced into the converter has a high percentage
