(FR) BANDE COMPOSITE D'ALLIAGE D'ALUMINIUM POUR TUBE D'ÉCHANGE DE CHALEUR À FILETAGE INTERNE ET SON PROCÉDÉ DE FABRICATION
(ZH) 内螺纹换热管用铝合金复合带材及其制造方法
Abstract:
(EN) An aluminum alloy composite strip for producing an internal threaded heat exchange tube, and a method for manufacturing the aluminum alloy composite strip. The method comprises the following steps: melting ingots; performing surface treatment; performing composite hot-rolling to obtain a hot-rolled composite strip comprising an external aluminum alloy layer and an internal aluminum alloy layer; performing cold rolling on the composite strip; annealing to obtain a completely softened composite aluminum strip; thread rolling, i.e., rolling threads on the surface of the internal aluminum alloy layer of the softened composite aluminum strip to obtain a threaded composite strip; and slitting the threaded composite strip to obtain a composite strip for manufacturing the heat exchange tube.
(FR) L'invention concerne une bande composite d'alliage d'aluminium pour la production d'un tube d'échange de chaleur à filetage interne, et un procédé de fabrication de la bande composite d'alliage d'aluminium. Le procédé comprend les étapes suivantes consistant à : faire fondre des lingots ; réaliser un traitement de surface ; effectuer un laminage à chaud du composite pour obtenir une bande composite laminée à chaud comprenant une couche d'alliage d'aluminium externe et une couche d'alliage d'aluminium interne ; effectuer un laminage à froid sur la bande composite ; recuire pour obtenir une bande composite d'aluminium totalement ramollie ; fileter par roulage, c'est-à-dire enrouler des fils sur la surface de la couche d'alliage d'aluminium interne de la bande composite d'aluminium ramollie pour obtenir une bande composite filetée ; et découper la bande composite filetée pour obtenir une bande composite pour la fabrication du tube d'échange de chaleur.
