Depuis plusieurs d\u00e9cennies, la technologie ultrasons laser est utilis\u00e9e dans l’industrie pour obtenir des informations dimensionnelles sur les produits en acier chauds. Par exemple, le d\u00e9ploiement d’ultrasons 2.0 a facilit\u00e9 la mesure en ligne et en temps r\u00e9el de l’\u00e9paisseur des parois des tubes et tuyaux sans soudure chauds, en utilisant la caract\u00e9ristique sans contact de la technologie laser-ultrasons.<\/p>\n

La large bande ultrasonique inh\u00e9rente aux ultrasons laser permet une analyse d\u00e9taill\u00e9e des fr\u00e9quences, ce qui permet des avanc\u00e9es telles que la mesure en temps r\u00e9el de la taille des grains. Auparavant, ces mesures \u00e9taient limit\u00e9es \u00e0 des environnements de laboratoire contr\u00f4l\u00e9s, impliquant g\u00e9n\u00e9ralement un simulateur thermom\u00e9canique. Cependant, une \u00e9quipe dirig\u00e9e par M. Mikael Malmstr\u00f6m \u00e0 SWERIM a r\u00e9cemment mis au point et exploit\u00e9 une jauge de taille de grain en ligne utilisant la technologie ultrasons laser pour les bobines d’acier chaudes.<\/p>\n

En collaboration avec EMG Automation, un prototype a \u00e9t\u00e9 install\u00e9 avec succ\u00e8s chez SSAB \u00e0 Borl\u00e4nge, en Su\u00e8de. La recherche approfondie de l’\u00e9quipe, publi\u00e9e dans la revue Applied Science, d\u00e9crit la m\u00e9thodologie employ\u00e9e pour extraire des donn\u00e9es sur la taille des grains \u00e0 partir des mesures d’att\u00e9nuation des ultrasons laser.<\/p>\n

Les r\u00e9sultats de leur \u00e9tude d\u00e9montrent effectivement la capacit\u00e9 de la technologie des ultrasons laser \u00e0 fournir des informations en temps r\u00e9el sur les propri\u00e9t\u00e9s m\u00e9caniques des bobines d’acier produites. Cette avanc\u00e9e ouvre de nouvelles possibilit\u00e9s aux producteurs d’acier pour am\u00e9liorer le contr\u00f4le des caract\u00e9ristiques de qualit\u00e9 de leurs produits.<\/p>\n
