Da die Walzguttemperatur beim Austritt aus der Zwischenstraße erfahrungsgemäß etwa 1.050 - 1.100 C° beträgt, kann mit den Kühlstrecken eine Kühlung des Walzgutstranges auf mindestens etwa 750 C° bewirkt werden. Die relativ langen Ausgleichstrecken hinter bzw. zwischen den Kühlstrecken erlauben es einen guten Temperaturausgleich zwischen Kern und Oberfläche des Walzgutstranges herbei zu führen und dadurch diesen im Maßfertigblock mit einer niedrigen, ausgeglichenen Walzguttemperatur fertig zu walzen. Experience has shown that the temperature of the rolling stock when it emerges from the intermediate line about 1,050 - 1,100 ° C, the cooling sections can cool the Rolled stock can be brought to at least about 750 ° C. The relatively long ones Compensating sections behind or between the cooling sections allow a good one Temperature compensation between the core and the surface of the rolling stock to bring about and thereby this in the custom-made block with a low, balanced Roll temperature to be rolled.
