Abstract

La présente invention se rapporte à un procédé pour améliorer la propreté de surface de la tôle d'acier et spécifiquement de la tôle d'acier destinée à être soumise à des opérations d'emboutissage. Le procédé est caractérisé en ce que, avant ou lors de la mise de la tôle sous forme de bobine à spires serrées avant recuit, ladite tôle est recouverte d'une substance capable de réagir avec le carbone amorphe existant sur la tôle en tant qu'élément polluant, de façon à former avec lui un composé volatil au cours du recuit de la tôle. Application notamment à la tôle d'emboutissage pour l'industrie automobile.
