Description
Walzwerk mit dünnen Arbeitswalzen, die je zwischen einem Paar stärkerer Stützwalzen gelagert sind Bei einer vorgeschlagenen Walzwerkskonstruktion wird die Verwendung extrem dünner Arbeitswalzen dadurch ermöglicht, daß nach Art von Sechsrollenwalzwerken angeordnete mittelstarke Stützwalzen nochmals durch stärkere Stützwalzen abgestützt werden, wobei im allgemeinen drei Stützwalzen auf jeder Seite angewendet werden.Rolling mill with thin work rolls, each between a pair of stronger ones Back-up rolls are mounted. In a proposed rolling mill construction, the The use of extremely thin work rolls is made possible by the fact that in the manner of six-roll mills arranged medium-strength backup rollers supported again by stronger backup rollers generally using three backup rolls on each side.
Die Erfinder haben gefunden, daß sich in manchen Fällen derartige Walzwerke dadurch verbilligen lassen, daß man zwei der äußeren Stützwalzen wegläßt und nur eine äußere Stützwalze gemäß der Abbildung anordnet. Obwohl bei dieser Anordnung die Kosten für zwei äußere Stützwalzen gespart werden, läßt sich doch eine genügend gute Abstützung der Arbeitswalzen dadurch .erreichen; daß man den Durchmesser der äußeren Stützwalzen C und C vergrößert und damit die Biegefestigkeit der einzigen äußeren Stützwalze größer macht als die Summe der Biegefestigkeiten von drei äußeren Stützwalzen bei der früher vorgeschlagenen Bauweise. Insbesondere läßt sich der Durchmesser der äußeren Stützwalzen C und C' über den größten Durchmesser hinaus vergrößern, der bei drei äußeren Stützwalzen bei den früher vorgeschlagenen Walzwerken aus Gründen der räumlichen Anordnung überhaupt in Frage kommen kann.The inventors have found that in some cases such rolling mills can be made cheaper by omitting two of the outer backup rolls and arranging only one outer backup roll as shown in the figure. Although this arrangement saves the cost of two outer back-up rolls, a sufficiently good support of the work rolls can thereby be achieved; that one increases the diameter of the outer backup rolls C and C and thus makes the flexural strength of the single outer back-up roll greater than the sum of the flexural strengths of three outer back-up rolls in the previously proposed construction. In particular, the diameter of the outer back-up rolls C and C 'can be increased beyond the largest diameter that can be considered in the case of three outer back-up rolls in the previously proposed rolling mills for reasons of spatial arrangement.
