Verfahren zur Herstellung einer phosphorreichen Eisenlegierung aus minderwertigen
Frischofenschlacken.
Die im Frischofen, z. B. im Martinofen oder im Konverter, sich bildende Schlacke ist bisher meist wertlos. Wenn die Schlacke des Eisen-oder Mangangehaltes wegen teilweise in dem Hochofen wieder aufgegeben wird, so wirkt der Phosphorgehalt verunreinigend, insbesondere bei den Qualiti1troheisensorten. Eine Verwertung des Phosphors der Frisch-

Der Generator wird durch dieses nebenhei ausgefülhrte. ein gut verkäufliches Erzeugnis liefernde Herstellungsverfahren nicht ungünstig beeinflusst.
Ist die Schlacke manganhaltig, was oft der Fall sein wird, so ergibt sich als Erzeugnis des Verfahrens ein phosphorreiches Spiegeleisen, welches beim Stahlschmelzen die

Process for making a phosphorus-rich iron alloy from inferior ones
Fresh furnace slags.
The in the fresh oven, z. B. in the Martin furnace or in the converter, slag that forms is usually worthless. If the slag is partly returned to the blast furnace because of its iron or manganese content, the phosphorus content has a contaminating effect, especially in the case of the quality pig iron types. A utilization of the phosphorus of the fresh

The generator is carried out by this one. does not adversely affect manufacturing processes that provide a salable product.
If the slag contains manganese, which will often be the case, the result of the process is a mirror iron rich in phosphorus, which is used when steel is melted

Can give phosphorus content.
It is not in itself new to produce liquid iron in the generator. Subject of

inferior slags of medium phosphorus content.
