Abstract

Procédé de fabrication de pièces de forme à partir de bandes de métal, par forgeage, poinçonnage et traitement thermique. Le formage des pieces est réalisé à froid à partir de bandes de métal enroulées en couronnes, les pièces sont ensuite chauffées localement, trempées et revenues en lits fluidisés de poudre réfractaire avant les opérations finales de grenaillage et protection. Fabrication en grande série de pièces telles que des attaches de rails.
