Steelmaking
Steelmaking
Steelmaking ist ein essentieller Prozess in der Produktion und im Handel mit Stahl. Es ist der Schritt, bei dem Rohstoffe wie Eisen und Kohlenstoff zu einem haltbaren und vielseitigen Material, dem Stahl, umgewandelt werden.
Was ist Steelmaking?
Das Steelmaking ist ein Prozess, bei dem Rohstoffe wie Eisen und Kohlenstoff zu Stahl verarbeitet werden. Stahl ist bekannt für seine Haltbarkeit, Festigkeit und Vielseitigkeit, die es zu einem sehr gängigen und wichtigen Material in Bau, Fertigung, Transport und viele andere Industrien macht.
Primärer und Sekundärer Steelmaking
Der Prozess des Steelmaking kann in zwei Stufen unterteilt werden: Das so genannte primäre und sekundäre Steelmaking. Beim primären Steelmaking wird Roheisen, das in Hochöfen aus Eisenerz gewonnen wird, mit Stahl- und Eisenschrott in Konvertern zu Rohstahl verarbeitet. Beim sekundären Steelmaking wird dieser Rohstahl weiter behandelt und verfeinert, um die endgültigen Eigenschaften des Stahls zu bestimmen.
Methoden des Steelmaking
Es gibt verschiedene Methoden des Steelmaking. Die älteste und traditionellste Methode ist das so genannte Thomas-Verfahren, das jedoch heutzutage kaum noch angewendet wird. Moderne Verfahren sind das Oxygen-Verfahren (LD-Verfahren) und das Electric Arc Furnace (EAF)-Verfahren. Das LD-Verfahren ist ein Oxidationsprozess unter Einblasen von Sauerstoff, während das EAF-Verfahren den Einsatz von Elektroden in einem Elektrolichtbogenofen erfordert.
Die Rolle des Steelmaking im Steel Trade
Im Stahlhandel spielt das Steelmaking eine fundamentale Rolle. Die Qualität der Stahlherstellung beeinflusst direkt den Wert und damit den Preis des Stahls auf dem Markt. Daher ist für Stahlproduzenten und Stahlhändler eine hohe Fertigungsqualität von entscheidender Bedeutung.
Aufgrund seiner Bedeutung verfügt der Stahlproduktionsmarkt über strenge Qualitätsstandards und Zertifizierungssysteme als Garantie für die Qualität und Sicherheit des Prozesses.
