Walzwerk Riva BES - Brandenburger Elektrostahlwerke modernisiert
von Hubert Hunscheidt

Das modernisierte Walzwerk umfasst vier Walzlinien, die bis zu 270 t/h niedrig-, mittel- und hochgekohlten Rundstahl mit Durchmessern von 5,5 bis 16 mm sowie Betonstahl mit Durchmessern von 6 bis 16 mm in Coils von 1575 kg produzieren.
Bei den neuen Verlegeköpfen handelt es sich um von Danieli patentierte Hightech-Ölfilm-Lagereinheiten, die Geschwindigkeiten von bis zu 140 m/s erreichen und dank vibrationsfreiem Betrieb eine hervorragende Betriebsstabilität, optimale Coilform und minimalen Wartungsaufwand bieten.
Eine Schlüsselrolle spielt auch die neueste Generation aktiver Andruckwalzen von Danieli, die mit elektrohydrostatischen Aktuatoren (EHA) ausgestattet sind. Sie sorgen für eine optimale Spalt-/Krafteinstellung über die gesamte Walzperiode und verhindern so Schlupf und Verschleiß der Walzen, was wiederum die Lebensdauer der Ringe erhöht.
Der wartungsfreie Betrieb wird durch ein adaptives Closed-Loop-System und einen störungsfreien Betrieb durch ein einfaches Selbstoptimierungsverfahren gewährleistet.
