Abstract

L'invention concerne un procédé servant à fabriquer en toute sécurité un produit plat en acier laminé à froid présentant une épaisseur ≤ 0,5 mm et apte à l'emboutissage et à l'étirage. Selon ledit procédé, un acier fondu, qui contient (en % en poids) jusqu'à 0,008 % de C, jusqu'à 0,005 % de AI, jusqu'à 0,043 % de Si, entre 0,15 et 0,5 % de Mn, jusqu'à 0,02 % de P, jusqu'à 0,03 % de S, jusqu'à 0,020 % de N ainsi que respectivement en option jusqu'à 0,03 % de Ti et jusqu'à 0,03 % de Nb, le reste étant du fer et des impuretés inévitables, est soumis, sachant qu'on renonce à un traitement au Ca, à un traitement métallurgique secondaire, qui comprend, outre un traitement sous vide, un traitement en poche de coulée et au cours duquel l'acier fondu à traiter est maintenu sous des scories dont les teneurs en Mn et en Fe cumulées ne dépassent pas 15 % en poids. On fabrique, à partir de l'acier fondu, une brame mince ou un feuillard coulé, lesquels sont ensuite laminés à chaud pour obtenir un feuillard à chaud présentant une épaisseur < 2,5 mm et sont bobinés pour former une bobine. Puis les feuillards à chaud sont laminés à froid pour obtenir un produit plat en acier présentant une épaisseur pouvant aller jusqu'à 0,5 mm. L'invention concerne par ailleurs un produit plat en acier produit de manière correspondante et les utilisations d'un produit plat en acier de ce type.
