Was ist Direct Reduced Iron?
Direct Reduced Iron (DRI) bezeichnet eine spezielle Form von Eisen. Dieses Eisen stellt in der Stahlproduktion und im Stahlhandel eine wichtige Zutat dar. Anders als herkömmliches Eisen wird DRI nicht in einem Hochofen gewonnen, sondern mit einem besonderen Verfahren. Genauer gesagt, nutzt man die Direktreduktion.
Das Verfahren der Direktreduktion
Bei der Direktreduktion nutzt man, wie der Name sagt, ein direktes Verfahren. Es wird nicht wie in einem Hochofen indirekt Eisen gewonnen. Stattdessen setzt man das Eisenerz direkt einem Reduktionsmittel aus. Dabei entsteht Direct Reduced Iron. Das Besondere: Das Eisen ist nahezu frei von Verschmutzungen. So kann man mit DRI sehr reinen Stahl herstellen.
Verwendung von Direct Reduced Iron
Direct Reduced Iron kommt in der Stahlindustrie zum Einsatz. Hier bewirkt es, dass der produzierte Stahl eine hohe Reinheit aufweist. Außerdem dient DRI als Ausgangsmaterial für die Weiterverarbeitung zu anderen Stahlerzeugnissen. Nicht zuletzt ist Direct Reduced Iron eine nachhaltiger Alternative zum herkömmlichen Hochofenverfahren. Es verbraucht weniger Energie und erzeugt weniger CO2.
Warum ist DRI wichtig?
Direct Reduced Iron bietet viele Vorteile. Es trägt zur Herstellung von hochreinem Stahl bei, der in vielen Bereichen benötigt wird. Dazu zählen etwa der Automobilbau, der Maschinenbau oder die Bauindustrie. Zudem ist die Produktion von DRI umweltfreundlicher als herkömmliche Verfahren. Deshalb nimmt seine Bedeutung in der Stahlindustrie und im Stahlhandel immer weiter zu.
