Abstract

Zum Walzen von Vollquerschnitten, z. B. Stabstahl und Draht, erhalten die Walzen 35, 36, 37, 38 von Walzgerüsten, die drei oder mehr Walzen aufweisen, gebogene Arbeitsflächen 12, die im Walzgut, insbesondere bei einem runden Einlaufquerschnitt 15, Einbuchtungen 5b einwalzen. Mit den zwischen den Einbuchtungen befindlichen Ausbuchtungen 5a ergibt sich ein Kleeblatt-Kaliber 5. Da im Bereich der Ausbuchtungen 5a das Material durch die starke Höhenabnahme aufgrund der Arbeitsflächen 12 der Walzen mitgezogen wird, erfolgt im Bereich der Ausbuchtungen 5a eine breitungsfreie Längenzunahme ohne wesentliche Höhenzunahme For rolling full cross sections, e.g. B. steel bars and wire, get the rolls 35, 36, 37, 38 from roll stands, the three or more rollers, curved work surfaces 12, the in the rolling stock, in particular with a round inlet cross section 15, Roll indentations 5b. With the between the indentations bulges 5a located in a cloverleaf caliber 5. As in the area of the bulges 5a, the material due to the sharp decrease in height due to the work surfaces 12 the rollers are pulled in the area of the bulges 5a a width-free increase in length without significant Height increase
