Abstract
Zum Walzen von Formstahl, insbesondere von Spundbohlen, wird üblicherweise eine Anzahl von jeweils mehrere Kaliberöffnun gen aufweisenden Gerüsten vorgesehen. Die Anzahl dieser Gerüste läßt sich reduzieren und damit der zu treibende Aufwand erheblich senken, wenn bspw. die ersten beiden oder ersten drei üblicherweise als schwere Vorgerüste ausgebil deten Kalibergerüste durch ein Universalgerüst 1, zweckmäßig zusätzlich mit einem zugeordneten Stauchgerüst 2, ersetzt werden. Die wesentliche erste Umformung der Bramme kann dann im Reversierbetrieb in diesem einen Universalgerüst mit entsprechend geformten Walzenballen erfolgen, und ein gege benenfalls unkontrolliert auftretender seitlicher Randsaum kann durch das Stauchgerüst in Grenzen gehalten werden. For the rolling of shaped steel, especially sheet piles usually a number of several caliber openings each against scaffolding. The number of these Scaffolding can be reduced and thus the one to be driven Significantly reduce effort if, for example, the first two or The first three are usually trained as heavy roughing stands Deten caliber frames by a universal frame 1, appropriate additionally replaced with an associated compression frame 2 will. The essential first forming of the slab can then in reverse operation with this one universal scaffold appropriately shaped roll bales take place, and a gege if necessary uncontrolled side edge hem can be kept within limits by the compression frame.
