Title
(DE) VORRICHTUNG ZUM VORWÄRMEN STANGENFÖRMIGER WERKSTÜCKE
(EN) DEVICE FOR PREHEATING ROD-LIKE WORKPIECES
(FR) DISPOSITIF POUR LE PRÉCHAUFFAGE DE PIÈCES EN FORME DE BARRE
Abstract
(DE)
Vorrichtung zum Vorwärmen stangenförmiger, metallischer Werkstücke, insbesondere Aluminiumstangen, mittels einer durch Rest- oder Abwärme eines in einer Aufheizvorrichtung zur Aufheizung der Werkstücke erfolgenden Verbrennungsprozesses beheizten Fluidströmung, wobei die Vorrichtung eine Vorwärmkammer zur Aufnahme zumindest eines Werkstücks aufweist, wobei dass zur Übertragung der Wärme von der Fluidströmung auf einen Wärmeträgerstrom in einer Fluidstromleitung zwischen einem Fluidstromanschluss und der Vorwärmkammer eine Wärmetauschereinrichtung vorgesehen ist, derart, dass die Vorwärmung des Werkstücks mittelbar über den in der Wärmetauschereinrichtung von der Fluidströmung aufgeheizten Wärmeträgerstrom erfolgt.
(EN)
A device for preheating rod-like, metal workpieces, in particular aluminium rods, by means of a fluid flow heated by residual heat or waste heat of a combustion process occurring in a heating device for heating the workpieces. The device has a preheating chamber for receiving at least one workpiece, wherein, in order to transfer the heat from the fluid flow to a heat transfer medium flow in a fluid flow line between a fluid flow connection and the preheating chamber, a heat-exchanger unit is provided in such a way that the workpiece is preheated indirectly via the heat transfer medium flow heated in the heat-exchanger unit by the fluid flow.
(FR)
Dispositif pour le préchauffage de pièces métalliques en forme de barre, en particulier de barres d'aluminium, au moyen d'un flux de fluide chauffé par la chaleur résiduelle ou les rejets thermiques d'un processus de combustion ayant lieu dans un dispositif de chauffage pour le chauffage des pièces, le dispositif présentant une chambre de préchauffage pour la réception d'au moins une pièce, un dispositif d'échange de chaleur étant prévu pour le transfert de la chaleur du flux de fluide à un flux de fluide caloporteur dans une conduite de flux de fluide entre un raccord de flux de fluide et la chambre de préchauffage, de sorte que le préchauffage de la pièce a lieu indirectement par l'intermédiaire du flux de fluide caloporteur chauffé par le flux de fluide dans le dispositif d'échange de chaleur.
