Title (EN) METHOD AND SYSTEM FOR MANUFACTURING A STEEL PRODUCT HAVING A COATING WITH SPANGLES, AND A STEEL PRODUCT HAVING A COATING WITH SPANGLES.
(FR) PROCÉDÉ ET SYSTÈME POUR LA FABRICATION D'UN PRODUIT EN ACIER AYANT UN REVÊTEMENT À PAILLETTES, ET PRODUIT EN ACIER AYANT UN REVÊTEMENT À PAILLETTES
Abstract:
(EN) The invention pertains to a method and system for manufacturing a steel product having a metallic coating with spangles. The method according to the invention comprises the following steps: -receiving a steel product (5) having a surface (6), wherein an oily substance is present at the surface (6) of the steel product (5), -removing the oily substance from the surface (6) of the steel product (5) by contacting the oily substance on the surface (6) of the steel product (5) with a plasma (24) in a non-oxidizing cleaning atmosphere, -after removing the oily substance from the surface (6) of the steel product (5), annealing the steel product (5) under a non-oxidizing annealing atmosphere, -applying the metallic coating on the steel product (5) by a hot-dip coating process.
(FR) L'invention concerne un procédé et un système pour la fabrication d'un produit en acier ayant un revêtement métallique à paillettes. Le procédé selon l'invention comprend les étapes suivantes :-la réception d'un produit en acier (5) ayant une surface (6), une substance huileuse étant présente au niveau de la surface (6) du produit en acier (5); l'élimination de la substance huileuse depuis la surface (6) du produit en acier (5) par la mise en contact de la substance huileuse sur la surface (6) du produit en acier (5) avec un plasma (24) dans une atmosphère de nettoyage non oxydante; suite à l'élimination de la substance huileuse de la surface (6) du produit en acier (5), le recuit du produit en acier (5) dans une atmosphère de recuit non oxydante; l'application du revêtement métallique sur le produit en acier (5) par un procédé de revêtement par immersion à chaud.
