Fortschrittliche Wasseraufbereitungsanlage für ESF Elbe-Stahlwerk in Riesa

von Hubert Hunscheidt

Der deutsche Stahlhersteller ESF Elbe-Stahlwerke Feralpi hat Danieli das Vertrauen für die Wasseraufbereitungsanlage für das im März 2022 bestellte Walzwerk ausgesprochen. Das neue, innovative Walzwerk, das in Riesa, Deutschland, errichtet werden soll, wird Qualitätsstäbe in Coils bis zu 8 Tonnen produzieren.

Die neue Wasseraufbereitungsanlage, die patentierte Technologien wie ZSP Zero-Scale PitTM und DanfilterTM umfasst, wird das Projekt vervollständigen. Das ZSP-Paket reduziert die Kosten für den Bau von Zundergruben für Walzwerke und Verarbeitungslinien. Anstatt ein tiefes unterirdisches Becken zu graben, um das Kontaktwasser zurückzugewinnen, wird der ZSP direkt unter dem Walzwerk installiert. Der Zunder, der sich dort ablagert, wird kontinuierlich aus der unterirdischen Rinne entfernt und an die Oberfläche gehoben, wo er in einem Standardbehälter gesammelt wird. Die Implementierung der Danieli Zero Scale Pit Lösung führt zu bemerkenswerten CapEx-Einsparungen ohne zusätzliche OpEx-Kosten und vereinfacht zudem die Wartungsarbeiten.

DanFilter, hochleistungsfähige Sandfilter mit Tiefenfiltration, erreichen Filtrationsraten von bis zu 60 m3/h/qm und sorgen für eine hervorragende Wasserqualität mit weniger als 10 ppm Schwebstoffen. Dies ermöglicht die Lieferung von kompakteren Anlagen mit weniger Filtern im Vergleich zum Standardtyp, was die Investitionskosten und den Platzbedarf der Anlage reduziert. Das Danieli-Patent umfasst die Funktionsweise und die Rückspülparameter sowie das Verteilungssystem. Darüber hinaus wird Danieli auch Partner der Feralpi Stahlwerke für die MEIP-Installation (Mechanik, Rohrleitungen, Elektrik) vor Ort sowohl für das Walzwerk als auch für die WTP sein, um sicherzustellen, dass die für das zweite Quartal 2024 geplante Inbetriebnahme pünktlich und erfolgreich durchgeführt wird.

Danieli bietet dank seiner Forschungs- und Entwicklungsarbeit und seiner Erfahrung in der Praxis eine umfassende Palette moderner Hilfsanlagen an. Es vervollständigt die Anlagen für Schmelzwerke und Walzwerke und steigert deren Wettbewerbsfähigkeit.
