Abstract

Eine Feinstahl- oder Drahtstraße mit einer mehrgerüstigen Vorstraße, einer mehrgerüstigen Zwischenstraße und einem aus 6 oder 8 oder 10 Walzgerüsten mit jeweils einem gemeinsamen Antrieb ausgerüsteten Fertigblock (7) ist dadurch gekennzeichnet, dass zumindest die letzten beiden Gerüste (23, 24) des Fertigblocks (7) mit je einem individuellen Antriebsaggregat (9, 10) ausgestattet sind, und dass die Antriebswellen (13, 13') der entkoppelbaren letzten beiden Walzgerüste (23, 24) die Hauptantriebswellen (27, 28) der gekoppelten Gerüste (22) schneiden.

Figure 00000001
A fine steel or wire mill with a multi-stand roughing mill, a multi-stand intermediate mill and a finishing block (7) equipped with 6 or 8 or 10 rolling stands, each with a common drive, is characterized in that at least the last two stands (23, 24) of the finishing block ( 7) are each equipped with an individual drive unit (9, 10) and that the drive shafts (13, 13 ') of the last two rolling stands (23, 24) that can be decoupled cut the main drive shafts (27, 28) of the coupled stands (22).
