Abstract

L'invention concerne un procédé de production de plaque brute pour plaque de traitement de surface destinée à une conserve au moyen d'une recuisson continue consistant à chauffer et à tremper une plaque laminée à froid d'un acier calmé à l'aluminium à carbone faible contenant C: 0,1 % ou moins en poids et N: 0,001 à 0,015 % en poids pour qu'elle atteigne une température supérieure à sa température de recristallisation, à refroidir, après avoir recristallisé, à une température entre 350 et 480 °C à une vitesse de refroidissement moyenne supérieure à 100 °C /sec et inférieure à 300 °C/sec, à effectuer un traitement de survieillissement sans refroidir après avoir effectué réchauffement, et à refroidir finalement après avoir effectué un traitement de survieillissement et un dressage par laminage à froid. La température de trempage est régulée selon le degré souhaité de cycle d'affinage et de chaleur depuis la première étape de refroidissement et est indépendante du degré d'affinage. Ce procédé peut servir à produire séparément différentes plaques brutes présentant divers degrés d'affinage dans une plage complète allant d'un matériau souple à un matériau dur au moyen d'un seul équipement CAL compact qui n'entraîne pas des coûts importants de fabrication, qui ne réduit pas la productivité ou le rendement, dont les coûts sont revus à la baisse et dont la stabilité est croissante.
