Pig iron: Was es ist und wie es entsteht

Pig iron ist ein grundlegendes Produkt in der Stahlindustrie. Den Namen erhält es aufgrund der traditionellen Form, in der es abgegossen wird. Es ähnelt kleinen Ferkeln, die an das Zentrum ihrer Mutter angedockt sind. Pig iron entsteht durch das Schmelzen von Eisenerz in einem Hochofen und wird hauptsächlich zur Herstellung von Stahl verwendet.

Wie wird Pig iron produziert?

Die Herstellung von Pig iron findet in Hochöfen statt. Dort wird Eisenerz bei extrem hohen Temperaturen geschmolzen, umgeschmolzen und mit Koks, einem Brennstoff mit hohem Kohlenstoffgehalt, kombiniert. Diese Kombination löst chemische Reaktionen aus, die Eisen und Schlacken, einen Abfallstoff, trennen. Was übrig bleibt, ist Pig iron, eine Art Roheisen mit hohem Kohlenstoffgehalt und zusätzlichen Elementen wie Silikon, Mangan, Schwefel und Phosphor.

Pig iron im Handel

Pig iron spielt eine wichtige Rolle im Stahlhandel. Es existiert ein globaler Markt für dieses Produkt, das an Stahlwerke und Gießereien auf der ganzen Welt verkauft wird. Diese nutzen Pig iron als Ausgangsmaterial für die Herstellung einer Vielzahl von Stahlprodukten. Die Marktpreise für Pig iron können stark schwanken, abhängig von Faktoren wie Nachfrage und Angebot, den Kosten für Rohmaterialien und Energie sowie globalen wirtschaftlichen Bedingungen.

Von Pig iron zu Stahl

Die Herstellung von Stahl aus Pig iron ist ein kritischer Prozess in der Stahlproduktion. Der hohe Kohlenstoffgehalt im Pig iron wird reduziert, in der Regel durch ein Verfahren namens Oxygen-Verfahren, um Stahl zu erzeugen. Durch weitere Verfahren kann der Stahl dann in viele verschiedene Typen und Qualitäten umgewandelt werden, die in einer Vielzahl von Anwendungen verwendet werden, vom Bau über die Automobilindustrie bis hin zu Haushaltsgeräten.

Zusammenfassung

Pig iron ist somit ein wichtiger Bestandteil in der Herstellung von Stahl. Es wird aus Eisenerz in einem Hochofen gewonnen und ist die Basis für eine Vielzahl von Stahlprodukten, die wir täglich in unserem Leben nutzen. Im Handel ist Pig iron ein globales Produkt, dessen Preis von einer Vielzahl von Faktoren beeinflusst wird.
