Abstract

"PROCESSO PARA A UNIãO DE TUBOS DE AçO A NERVURAS DE ALUMìNIO". No processo para a união de tubos de aço a nervuras de alumínio é aplicada, primeiramente, sobre as superfícies dos tubos de aço ou das nervuras de alumínio uma camada de uma liga zinco-alumínio com um componente de alumínio de 0,5%-20% e, depois disso, antes ou por ocasião do contato mecânico das nervuras de alumínio com os tubos de aço é introduzido entre os tubos de aço e as nervuras de alumínio, a temperatura ambiente, um fundente em forma de tetrafluoreto de alumínio de césio. Em seguida, os tubos de aço dotados das nervuras de alumínio são aquecidos em um forno a uma temperatura de solda entre 370<198>C e 470<198>C e, por fim, expostos para o resfriamento a temperatura ambiente. Alternativamente a isso, pode ser aplicada, primeiramente, sobre as superfícies dos tubos de aço ou das nervuras de alumínio uma camada de uma liga zinco-alumínio com um componente de alumínio de 0,5%-20% e, depois disso, a temperatura ambiente, é levado, pelo menos nas zonas de contato, um fundente em forma de tetrafluoreto de alumínio de césio sobre as nervuras de alumínio. Depois disso, as nervuras de alumínio são levadas em contato mecânico com os tubos de aço aquecidos a uma temperatura de solda entre 370<198>C e 470<198>C e, por fim, expostos para o resfriamento a temperatura ambiente.
