Abstract
Die Erfindung betrifft ein Verfahren zum Führen von sich um die Längsachse drehendem, langgestrecktem, hohlzy lindrischem Walzgut mittels eines unterhalb der Walzachse angeordneten, in Walzachsrichtung anstellbaren Führungs mittels. Um ein Verfahren zu entwickeln, um das lang gestreckte, hohlzylindrische Walzgut genau auf Walzmitte zu führen, ohne dabei den wendelförmigen Vorschub zu be hindern, wird vorgeschlagen, daß ein parallel zur Walz achse liegender Oberflächenbereich mindestens eines Führungsmittels während des Walzvorganges an die Ober fläche des Walzgutes überwiegend entgegen der Schwer kraftrichtung zur Anlage gebracht wird. The invention relates to a method for guiding itself elongated, hollow cylinder rotating about the longitudinal axis Lindritic rolling stock using one below the rolling axis arranged, adjustable in the rolling axis direction by means of. To develop a process that lasts long stretched, hollow cylindrical rolling stock exactly on the middle of the roll to guide without being the helical feed prevent, it is proposed that a parallel to the roll Axial surface area of at least one Guide means to the upper during the rolling process area of the rolling stock mainly against the gravity direction of force is brought to the system.
