Was ist Lime in Bezug auf Stahlproduktion und Stahlhandel?
In der Welt der Stahlproduktion und des Stahlhandels ist 'Lime' ein Begriff, der sich auf gebrannten oder gelöschten Kalk bezieht. Kalk, chemisch als Calciumcarbbonat bekannt, spielt eine wesentliche Rolle bei der Herstellung von Stahl.
Die Bedeutung von Lime in der Stahlindustrie
Lime ist ein unerlässlicher Bestandteil bei der Herstellung von Stahl. Es ist sowohl ein Fluxmittel als auch ein Reinigungsmittel. Es hilft dabei, unerwünschte Verunreinigungen wie Silizium, Phosphor und Schwefel aus dem Eisen zu entfernen. Darüber hinaus wird Lime auch als Schutzbeschichtung verwendet, die den Ofen vor Schäden schützen kann.
Wie wird Lime in der Stahlproduktion eingesetzt?
Lime wird in der Stahlindustrie großflächig eingesetzt. Bei der Roheisenherstellung wird Kalkstein, eine natürliche Form von Lime, mit dem Erz und Koks im Hochofen vermischt. Der dabei entstandene Kalk reagiert mit den Verunreinigungen im Erz und bildet Schlacke. Diese Schlacke kann anschließend abgeschöpft und entsorgt oder weiterverarbeitet werden.
Lime im Stahlhandel
Lime hat auch im Stahlhandel seinen Platz. Händler von Rohstoffen für die Stahlproduktion haben auch Lime in ihrem Sortiment, da es eine wesentliche Zutat im Herstellungsprozess ist. Daher sind Informationen über Lime, dessen Qualität und Preis, für Stahlhändler von großer Bedeutung.
Zusammenfassung
Obwohl Lime möglicherweise nicht das erste ist, was einem in den Sinn kommt, wenn man an Stahl denkt, spielt es eine enorm wichtige Rolle in der Stahlproduktion und dem Stahlhandel. Durch seine vielfältige Rolle in der Produktion, von der Entfernung unerwünschter Verunreinigungen bis hin zur Schutz des Hochofens, ist Lime ein unverzichtbarer Bestandteil der Stahlindustrie.
