Hubbalkenofen für das Stahlwerk Annahütte

von Hubert Hunscheidt

Die Technologie und Ausrüstung von Danieli Centro Combustion wurde vom Stahlwerk Annahütte Max Aicher für einen kompletten Hubbalkenofen zum Wiederaufwärmen von Knüppeln ausgewählt, der im Rahmen einer umfassenden Modernisierungsstrategie in Ainring-Hammerau, Deutschland, installiert wird. Produziert werden hochwertige Spezialstähle und Gewindestangen, die im Maschinenbau sowie in der Automobil- und Werkzeugindustrie Verwendung finden.

Der neue Ofen mit einer Leistung von 80 Tonnen pro Stunde wird das Walzwerk mit perfekt erwärmten Knüppeln versorgen, die eine präzise Temperaturgleichmäßigkeit aufweisen, die eine hohe Qualität der Walzprodukte gewährleistet. Die Investition garantiert dem Stahlwerk Annahütte einen wirtschaftlicheren und umweltfreundlicheren Betrieb, da der Energieverbrauch und die damit verbundenen CO2-Emissionen reduziert werden. Auch die NOx-Emissionen werden auf ein Minimum reduziert. Die Feuerungsanlage wird mit den von Danieli patentierten wasserstofftauglichen Hydromab-Brennern ausgestattet.

Zum Lieferumfang von Danieli gehören auch die Energieverteilung des Ofens, die Automatisierung, die Mensch-Maschine-Schnittstellen sowie die L1- und L2-Prozesssteuerungen mit mathematischen Modellen zur Optimierung des Heizprozesses. Das Materialhandling vor und nach dem Ofen, die Hydrauliksysteme und die Verbrennungstechnik einschließlich der Verbrennungsluftvorwärmung und des Abgassystems vervollständigen die Anlage.

Die Inbetriebnahme des neuen Nachwärmofens ist für September 2024 geplant.
