Abstract
Ein Verfahren zum Walzen von strangförmigem profilierten Walzgut vermittels von mehr als zwei jeweils Kaliberrinnen aufweisenden, sternförmig angeordneten Walzen (21,23) mit sich beid seitig an die Kaliberrinne anschließenden, nach außen sich verjüngenden kegelstumpfartig geformten Mantelbereichen (25) soll so weitergebildet werden, daß sich enge Toleranzen einhalten lassen. Hierzu werden die Kaliberwalzen (21,23) mit einer die Walz kraft um eine Vorspannkraft überschreitenden Anstellkräften so gegeneinander angestellt, daß die Mantelbereiche (25) der Walzen, sich direkt unter Einwirkung der Vorspannkraft auf einander abstützend, aufeinander ablaufen. Durch elastische Ausbildung der Stützbereiche läßt sich das umschlossene Kaliber durch Steuern oder Regeln der Vorspannkraft auf gewünschte Werte einstellen. A method of rolling extruded profiled Rolled material by means of more than two caliber channels having rollers arranged in a star shape (21, 23) with both to the side of the caliber channel, to the outside tapered frustoconical shaped shell areas (25) be trained in such a way that close tolerances are maintained to let. For this purpose, the caliber rollers (21, 23) with a roller force exceeding a pre-tensioning force so against each other that the jacket areas (25) of Rolling up directly under the influence of the preload supporting each other, running towards each other. Through elastic Training of the support areas can be the enclosed Caliber by controlling or regulating the preload Set the desired values.
