Patentirt im Deutschen Reiche vom 17. Mai 1898 ab.Patented in the German Empire on May 17, 1898.
Vorliegende Erfindung bezweckt in erster Linie die Entfernung des Phosphors aus Eisen, kann jedoch auch zur Entphosphorung anderer Metalle, z. B. Kupfer, in Anwendung gebracht werden.The present invention is primarily intended to remove phosphorus from iron, however, it can also be used for dephosphorization of other metals, e.g. B. copper, brought into use will.
Der Erfinder hat beobachtet, dafs der Phosphor in Gesteinen, Schlacken u. s. w. vorzugsweise in Verbindung mit den seltenen Erden und deren Metallen vorkommt, indem er Monazit, Xenotim und andere ähnliche Phosphate bildet.The inventor has observed that phosphorus is preferred in rocks, slag, and so on occurs in connection with the rare earths and their metals by monazite, Forms xenotime and other similar phosphates.
Er hat ferner gefunden, dafs es möglich ist, bei der Stahlerzeugung nach dem basischen Verfahren diejenigen Phosphorreste, welche sich nicht mit dem Kalk verbinden, sondern in dem geschmolzenen Metall zurückbleiben, ganz oder theilweise mit Hülfe der seltenen Erden bezw. ihrer Metalle oder deren Carbide, Fluoride, Cyanide, Silicate oder anderer solcher Metallsalze oder mit Mischungen dieser Körper zu entfernen. Diese Wirkung beruht darauf, dafs die Oxyde der seltenen Erden, insbesondere Ceroxyd, stärker basisch sind bezw. eine gröfsere Affinität zum Phosphor bezw. der Phosphorsäure haben, als Kalk.He has also found that it is possible to use basic steel in steel-making Process those phosphorus residues that do not combine with the lime, but remain in the molten metal, wholly or partly with the aid of the rare ones Earth resp. their metals or their carbides, fluorides, cyanides, silicates or other such To remove metal salts or mixtures of these bodies. This effect is based on that the oxides of the rare earths, in particular cerium oxide, are more basic or. one greater affinity for phosphorus respectively. of phosphoric acid than lime.
Die vorliegende Erfindung besteht demnach darin, das geschmolzene phosphorhaltige Metall mit seltenen Erden, deren Metallen oder den oben erwähnten Verbindungen zwecks Entphosphorung in Berührung zu bringen.The present invention thus consists in the molten phosphorus-containing metal with rare earths, their metals or the compounds mentioned above for the purpose of dephosphorization to bring in touch.
Bekanntlich werden unter der Bezeichnung »seltene Erden« die Oxyde des Cer, Thor, Lanthan, Didym, Erbium, Terbium, Yttrium u. s. w. zusammengefafst, welche hauptsächlich in den Mineralen Monazit, Xenotim und anderen Phosphaten vorkommen. Die erwähnten Metalle werden auch als die Metalle der Cergruppe bezeichnet.It is well known that the oxides of cerium, thor, Lanthanum, didymium, erbium, terbium, yttrium, etc., summarized, which mainly occur in the minerals monazite, xenotime and other phosphates. The mentioned Metals are also referred to as the metals of the cerium group.
Bei der Entphosphorung von Stahl oder Eisen wird das geschmolzene Metall mit den Oxyden der vorbenannten seltenen Erden oder diesen Elementen selbst oder mit den Carbiden in Berührung gebracht. Eine solche Behandlung des Eisens oder Stahls ist sowohl beim basischen He,rdprocefs als auch beim basischen Bessemerprocefs anwendbar. Zu dem genannten Zwecke können als entphosphorende Agenden auch Legirungen oder Verbindungen der genannten Metalle der Cergruppe bezw. deren Carbide mit Eisen oder mit Eisen und Magnesium (Ferromagnesium) in Anwendung gebracht werden, und es hat sich gezeigt, dafs gerade bei Verwendung solcher Verbindungen die vollständige Ausscheidung des Phosphors bezw. die Verschlackung der Phosphate und Phosphide vor sich geht.When steel or iron is dephosphorized, the molten metal is mixed with the Oxides of the aforementioned rare earths or these elements themselves or with the carbides brought into contact. Such treatment of iron or steel is both at basic He, rdprocefs as well as the basic Bessemerprocefs applicable. To the above Purposes can bezw as dephosphoric agendas also alloys or compounds of the mentioned metals of the cerium group. their carbides with iron or with iron and magnesium (ferromagnesium) in use and it has been shown that it is precisely when such compounds are used the complete excretion of phosphorus bezw. the slagging of phosphates and Phosphide is going on.
Natürlich hängt die Menge des zur Entphosphorung dienenden Mittels von dem Phosphorgehalte des zu reinigenden Metalles und von der chemischen Zusammensetzung des Mittels selbst ab. Wenn z. B. beim Roheisen der Procentsatz an Phosphor durch die Analyse bestimmt ist, kann die erforderliche Menge des Zuschlagmittels vom Hüitenchemiker leicht bestimmt werden. So stellt sich beispielsweise nach den chemischen Aequivalenten für Ceroxyd das Verhältnifs folgendermafsen:Of course, the amount of dephosphorus used depends on the phosphorus content the metal to be cleaned and the chemical composition of the agent itself. If z. B. the pig iron Percentage of phosphorus determined by the analysis can be the required amount of the The aggregate can easily be determined by the Hüitenchemiker. So arises, for example according to the chemical equivalents for cerium oxide, the ratio is as follows:
Phosphor °>54; Phosphorus °> 54 ;
Ceroxyd 2,83,Ceria 2.83,
d. h. die Menge des Ceroxyds würde procentualiter etwa fünf- bis sechsmal so grofs seind. H. the amount of ceria would be about five to six times as great in percentage terms
müssen als der durch die Analyse festgestellte Phosphorgehalt der Charge.must than the phosphorus content of the batch determined by the analysis.
Wie bereits erwähnt, kann der beschriebene Entphosphorungsprocefs auch für andere Metalle angewendet werden.As already mentioned, the dephosphorization process described can also be used for other metals be applied.
Die zur Entphosphorung dienenden Agentien werden entweder mit dem Metall gemischt, oder der Ofen bezw. die Birne wird damit ausgekleidet.The agents used for dephosphorization are either mixed with the metal, or the furnace respectively. the pear is lined with it.
