Abstract

Dans une machine à papier, un cylindre (22) est composé de deux parties: une enveloppe de base métallique (38) en acier allié classique coulé par centrifugation et une enveloppe extérieure mince (40) en un matériau à diffusivité thermique élevée. L'enveloppe extérieure (40) possède une épaisseur d'un à quelques dizièmes de pouce et est en contact étroit avec la surface de l'enveloppe de base en acier allié (38). Les matériaux classiques présentant une diffusivité thermique élevée et constituant l'enveloppe extérieure (40) sont le cuivre et l'aluminium. On peut fabriquer le cylindre (22) par projection à la flamme d'une couche de cuivre d'environ deux dizièmes de pouce d'épaisseur sur la surface d'une enveloppe de base en acier allié (38). On utilise le cylindre (22) afin d'améliorer le transfert thermique sur une bande de papier dans, par exemple, un cylindre sècheur à impulsions ou une calandre.
