PATENTAMT.PATENT OFFICE.
Im Patent 197591 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 oder nicht brikettierte Mischung von eisenoxydhaltigen Stoffen und gelöschtem Kalk dem Bade zugesetzt wird. Durch dies Verfahren wird eine schnelle Verbrennung des Phosphors erzielt, während die Verbrennung des Eisens, der Abbrand, auf ein geringes Maß beschränkt wird, und man erhält eine Schlacke von sehr hohem Phosphorgehalt.Patent 197591 describes an invention which consists in the fact that in the representation of steel after the Thomas process towards the end of the decarburization or during the Dephosphorization of a briquetted or non-briquetted mixture of iron oxide Substances and slaked lime is added to the bath. This process creates a rapid combustion of the phosphorus achieved while the combustion of the iron, the Burn-off, is limited to a low level, and a slag of very high is obtained high in phosphorus.
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, während der größere Teil von der Schlacke aufgenommen wird.It has now been shown that some of the iron oxides in the to be added Mixture can advantageously be replaced by oxides of manganese. The effect is that one small part of the .Manganese oxide is reduced by the phosphorus of the iron bath, while the greater part is taken up by the slag.
Da die Schlacke hierdurch dünnflüssiger wird, so wird durch den Zusatz von Manganoxyden die Entphosphorung des Eisenbades noch weiter erleichtert.Since the slag becomes thinner as a result, the addition of manganese oxides the dephosphorization of the iron bath is made even easier.
Das Verfahren wird so ausgeführt, daß der in den Konverter einzuführenden Mischung von Eisenoxyden und Kalkhydrat hochprozentige oxydische Manganerze zugesetzt werden, worauf das Ganze brikettiert wird.The process is carried out so that the mixture to be introduced into the converter high percentage oxidic manganese ores of iron oxides and hydrated lime are added, whereupon the whole thing is briquetted.
Es sei übrigens bemerkt, daß der Zusatz von Manganoxyden beim basischen Bessemerprozeß, und zwar als Ersatz des Kalkes bereits vorgeschlagen worden ist.It should be noted, by the way, that the addition of manganese oxides in the basic Bessemer process, and that has already been proposed as a replacement for lime.
