Title (EN) STRUCTURAL BODY AND METHOD FOR COLD ROLLING
(FR) CORPS STRUCTUREL ET PROCEDE DE LAMINAGE A FROID
Abstract:
(EN) A structural body and a method for cold rolling capable of continuously performing operations ranging from the rolling to the cutting of a deformed rolled material, the method comprising the step of providing a tension to the deformed rolled material passing through processes ranging from the rolling to a straightening, whereby a cost reduction and an energy saving can be achieved by eliminating the process annealing and the cleaning steps such as pickling and chemical conversion coating treatment of the deformed rolled material, a material loss can be suppressed to 5% or less, a dimensional variation of 0.05 mm or less, an increase in straightness of the material including the end parts after cutting, and a final accuracy of 0.1 mm can be provided, a lead time as a time required for processing can be remarkably shortened by in−line, and a running cost and a cost required for equipment can be reduced.
(FR) La présente invention concerne un corps structurel et un procédé de laminage à froid capable d'effectuer des opérations en continu partant du laminage à la découpe d'un matériau laminé déformé. Ce procédé consiste à appliquer une pression au matériau laminé déformé passant à travers un processus partant du laminage jusqu'à un dressage. On peut réaliser des économies d'énergie et réduire les coûts en supprimant le traitement de recuit et les étapes de nettoyage telles que le traitement de décapage et de revêtement de conversion chimique du matériau laminé déformé. On peut supprimer les pertes de matériau ou les maintenir au plus à 5 %, on peut limiter les variations de dimension à 0,05 mm, voire à une valeur inférieure, on peut améliorer la rectitude du matériau, y compris des extrémités après la découpe, on peut obtenir une précision finale de 0,1 mm, on peut réduire de façon remarquable les délais d'exécution du processus par une organisation en ligne et on peut réduire les coûts d'utilisation et le coût des installations.
