- Strangguss- und Heißwalzanlage zur Parallel-Simultanfließerzeugung von einer Vielzahl von Stangen oder Drähten, welche Stranggussmittel (1) mit Fließformungsmitteln (10) zur fortlaufenden Lieferung auf mehreren Linien zur parallelen Herstellung einer Vielzahl von Streifen/Stangen/Drähten sowie Vertikal- und Horizontalzwalmittel zum fortlaufenden Heißwalzen derselben umfasst, dadurch gekennzeichnet, dass:die besagte Fließformstanze mindestens "n"=4 gefluchtete, jeweils voneinander getrennte Formungslöcher besitzt, um direkt eine Anzahl "n" der besagten, zu walzenden Streifen/Stangen herzustellen, wobei "n" eine gerade Zahl ist;die besagte Fließformstanze für Stranggussmaterial mit einem Zugmittel mit Quetschrollen verbunden ist, um das besagte Stranggussmaterial durch die Fließformstanze hindurchzuzwingen, so dass dieses die Form einer Vielzahl von Würsten einnimmt, deren Form rund, oval oder vieleckig sein kann;nach den besagten Quetschzugrollen (2-3) ein tunnelförmiger Induktionsvorwärmofen (5) vorgesehen ist; dervon einem Loop-Kontrollsystem der vorlaufenden Abschnitte gefolgt ist, die locker gehalten werden, um die Geschwindigkeitsvariationen zwischen den vor- und nachgeschalteten Abschnitten zu kompensieren;wobei nach besagtem Kontrollsystem eine Reihe von Walzgerüsten folgen, die dazu bestimmt sind, den Querschnitt der Walzprodukte von 60-70 mm auf ca. 12 mm zu reduzieren, unter Zunahme der Periphergeschwindigkeit der Walzzylinder von 14 m/min am Einlauf auf ca. 12 m/sek. am Ausgang undwobei nach den besagten Walzgerüsten ein Umführungssystem vorgesehen ist, das wie das vorhergehende ebenfalls mit einem Loop-Kontrollsystem ausgestattet ist für mindestens "n"/2 Universalwalzblöcke (6-7W) mit 12 Walzrollenpaargruppen (VL-VR), die in Form eines gleichschenkeligen Dreiecks (02, 03, 04) gegenüberliegenden Paaren angeordnet sind zwecks Walzung von zwei parallelen und gegenüberliegenden Abschnitten/Drähten in drei Durchgängen mit einer peripheren Walzgeschwindigkeit der Rollen von ca. 85 m/sek. (L1-L2) zu walzen;
- Strangguss- und Heißwalzanlage gemäß Anspruch 1, dadurch gekennzeichnet, dass die besagten Walzgerüste ausschließlich 6 horizontale Walzrollen besitzen, die sich mit den Rotationsmitteln des um 90° (iv) vorlaufenden Abschnitts abwechseln.
- Strangguss- und Heißwalzanlage gemäß Anspruch 1, dadurch gekennzeichnet, dass die besagten Walzgerüste sowohl horizontal (7) als auch vertikal (8) sind, wobei die vertikalen Walzgerüste die Anzahl der vertikalen Walzrollenpaare "n" umfassen, die auf zwei parallele, nebeneinanderliegende Reihen unterteilt sind mit einem Walzkanal, der um den halben Achsabstand versetzt angeordnet ist, wobei jede Reihe "n"/2 vertikale Walzrollenpaare umfasst, damit abwechslungsweise ein Abschnitt vom Walzrollenpaar der ersten Reihe und der angrenzende Abschnitt vom Walzrollenpaar der zweiten Reihe gewalzt wird.
- Anlage gemäß Anspruch 1, dadurch gekennzeichnet, dass jeder Walzblock mit zwei horizontalen Parallelwalzreihen (6 - 7W) drei periphere Übertragungswellen eines gleichschenkeligen Dreiecks (02, 03, 04) umfasst, wobei die beiden unteren peripheren Achsen (03, 04) das vertikale Rollenpaar (VR-VRR) antreiben, deren Achse nach außen geneigt sind (VL), während die obere periphere Achse (02) Walzrollenpaare trägt (OR-RR), die rechtwinklig deckungsgleich mit den beiden besagten Walzlinien (L1, L2) liegen.
