Description
Auf Grund zahlreicher Versuche ist es erwiesen, daß ein Zusatz von Titan imstande ist, die Eigenschaften von Stahl und Gußeisen wesentlich zu verbessern. Die Versuche, das Titan in metallischer Form zuzusetzen, haben infolge der geringen Legier fähigkeit dieses Metalles sowie des hohen Schmelzpunktes und des. geringen spezifischen Gewichtes nur sehr schlechte Ergebnisse gezeitigt, und die Fachleute (vgl. «Stahl und Eisen«, 1909, 29. Jahrgang, Nr. 41, S. 1594) stehen jetzt auf demNumerous experiments have shown that titanium can be added is to significantly improve the properties of steel and cast iron. The attempts at that To add titanium in metallic form, have this ability due to the low alloying ability Metal as well as the high melting point and the low specific weight produced poor results, and the experts (see "Stahl und Eisen", 1909, 29th year, No. 41, p. 1594) are now on the
.·,·. Standpunkte, daß, wenn man einen vollen Erfolg erzielen will, man nicht reines Titan, sondern eine Eisen-Titanlegierung verwenden muß, welche 10 bis 15 Prozent Titan und nicht mehr enthalten dürfe. Gegen die Verwendung eines höher prozentigen Ferrotitans, welche in vielen Fallen wünschenswert wäre, werden dieselben Gründe geltend gemacht, wie gegen die Verwendung von metallischem, d. h. hochprozentigem Titan allein.. ·, ·. Viewpoints that when you get a full If you want to achieve success, you don't use pure titanium, but an iron-titanium alloy must, which may contain 10 to 15 percent titanium and no more. Against the use a higher percentage ferrotitanium, which would be desirable in many cases, the same reasons are asserted as against the use of metallic, d. H. high-percentage titanium alone.
' ' 'i Es hat sich nun gezeigt, daß man auch eine an Titan höher prozentige Legierung mit gutem Erfolge zur Reinigung von Stahl- und Gußeisenbädern benutzen kann, wenn man dieser Legierung als dritte Komponente Aluminium hinzufügt, also eine Eisen-Titan-Aluminiumlegierung verwendet. Durch die Verwendung einer solchen höher prozentigen Titanlegierung gelingt die Reinigung von Stahl- und Gußeisenbädern (durch Bindung des Stickstoffs, Desoxydation, Entfernung des Schwefels usw.) viel leichter und schneller als bei Anwendung einer 10 bis 15 prozentigen Legierung. Man verwendet am besten Legierungen von 15 bis 35 prozentigem Titangehalt, mit etwa 10 Prozent an Aluminium vom Gehalte des Titans, d. h. also 1,5 bis 3,5 Prozent Aluminium, doch kann der Aluminiumgehalt auch größer sein. Die Wirkung des Aluminiumzusatzes zu der Eisen-Titanlegierüng besteht darin, daß nicht nur der Schmelzpunkt heruntergesetzt, sondern auch die Legierfähigkeit bedeutend erhöht wird.'' 'i It has now been shown that you too an alloy with a higher percentage of titanium with good results for cleaning steel and Cast iron baths can be used if aluminum is added to this alloy as a third component, i.e. an iron-titanium-aluminum alloy used. By using such a higher percentage titanium alloy the cleaning of steel and cast iron baths succeeds (by binding the Nitrogen, deoxidation, removal of sulfur, etc.) much easier and faster than when using a 10 to 15 percent alloy. It is best to use alloys 15 to 35 percent titanium content, with about 10 percent aluminum content of titanium, d. H. So 1.5 to 3.5 percent aluminum, but the aluminum content can also be bigger. The effect of adding aluminum to the iron-titanium alloy is that not only the melting point is lowered, but also the alloyability is increased significantly.
Derartige Eisen-Titan-Aluminiümlegierungen lassen sich sehr leicht und in jeder gewünschten Zusammensetzung auf aluminothermischem Wege erzielen. Die so gewonnenen Legierungen haben noch den Vorzug, daß sie kohlefrei sind.Such iron-titanium-aluminum alloys can be very easily and in any desired composition on aluminothermic Achieve ways. The alloys obtained in this way still have the advantage that they are carbon-free are.
Als besonders brauchbar hat sich eine 24 bis 25 prozentige Titan-Eisenlegierung erwiesen, die 3 Prozent Aluminium enthält.A 24 to 25 percent titanium-iron alloy has proven to be particularly useful, which contains 3 percent aluminum.
