Non-metallic inclusions
Definition von Non-metallic inclusions
Wenn wir den Begriff Non-metallic inclusions hören, kann es zunächst ein wenig verwirrend sein. Aber, keine Angst! Wir sind hier, um es zu erklären. Non-metallic inclusions sind kleine, nichtmetallische Partikel, die sich in Metallen, insbesondere Stahl, festsetzen können. Sie können aus Oxiden, Sulfiden, Silikaten oder einer Mischung dieser Materialien bestehen. Du kannst dir Non-metallic inclusions wie Sand in einem Meer von Metall vorstellen.
Non-metallic inclusions und Stahlherstellung
Im Kontext der Stahlproduktion sind Non-metallic inclusions oft unerwünscht. Sie können die Eigenschaften des fertigen Stahls und seine Leistung in der Anwendung beeinflussen. Daher ist es wichtig, die Inclusions in der Produktion so gut wie möglich zu reduzieren. In jedem Fall unternehmen Stahlwerke erhebliche Anstrengungen, um die Menge dieser Inclusions zu reduzieren.
Arten von Non-metallic inclusions
Es gibt verschiedene Arten von Non-metallic inclusions. Die gebräuchlichsten sind Oxid-Inclusions, Sulfid-Inclusions und Silikat-Inclusions. Oxide sind üblicherweise das Ergebnis von Sauerstoffreaktionen in der Schmelze, während Sulfide meist durch Schwefelverunreinigungen entstehen.
Umgang mit Non-metallic inclusions
Die Steel producers haben Techniken und Verfahren entwickelt, um Non-metallic inclusions zu reduzieren oder zu entfernen. Ein gebräuchlicher Ansatz ist das Nutzen von Filtern und Schlacken, die die Inclusions aufnehmen. Darüber hinaus gibt es Prozesse, die die Inclusions verkleinern, um deren Auswirkungen zu minimieren.
Non-metallic inclusions und Stahlhandel
Im Stahlhandel ist es wichtig, die Menge der Non-metallic inclusions zu kennen. Kunden wollen Stahl von hoher Qualität und in vielen Fällen kann ein hoher Gehalt an Inclusions auf Probleme hinweisen. Darum prüfen Stahlhändler oft auf das Vorhandensein und die Menge von Inclusions.
