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.
