Abstract

Bei diesem Verfahren wird unmittelbar vor einer Umformung des sich in Längsrichtung bewegenden strangförmigen Gutes (1), wie Draht, Rohr, Band, Stange und Profil unmittelbar vor der Umformzone ein definiertes Temperaturfeld erzeugt und räumlich begrenzt. Dazu wird ein Teil der bei der Umformung entstehenden und entgegen der Bewegungsrichtung des Gutes zurückgeführten Wärmemenge genutzt. Gleichzeitig mit der Aus­ bildung des Termperaturfeldes wird ein Reaktionsraum mit einer im Vergleich zur Umgebungstemperatur erhöhten Temperatur erzeugt und dabei ein Temperaturbereich so eingestellt, daß sich im Reaktionsraum ein plastisch bis flüssiger Zustand des auf dem Gut aufgebrachten Beschichtungswerkstoffes ergibt und gelangt so durch die Umformzone. Die Vorrichtung umfaßt ein oder mehrere Elemente (6, 8, 10), wie ebene oder gekrümmte Platten, Siebe, Nezte oder Rohre, die vor der Umformeinrichtung (2, 3, 4) so angeordnet sind, daß sie keine unmittel­ bare Berührung zum strangförmigen Gut (1) haben und über Wärmeleiter (5) mit der nachfolgenden Umformeinrichtung (2, 3, 4) verbunden sind. In this method, immediately before the Longitudinally moving strand-like material (1), such as wire, pipe, tape, A defined bar and profile immediately in front of the forming zone Temperature field generated and limited in space. To do this, part of the arising during the forming process and against the direction of movement of the Good returned amount of heat used. Simultaneously with the out formation of the temperature field becomes a reaction space with an im In comparison to the ambient temperature, the temperature is increased while doing so a temperature range is set so that in the reaction chamber plastic to liquid state of the applied to the goods Coating material results and passes through the forming zone. The device comprises one or more elements (6, 8, 10), such as flat or curved plates, sieves, nezte or pipes that in front of the Forming device (2, 3, 4) are arranged so that they are not immediate have clear contact to the strand-like material (1) and via heat conductor (5) are connected to the subsequent forming device (2, 3, 4).
