Abstract: front page image
(EN)The present invention relates to a hot-dip galvanized steel plate which is applicable as a material for a vehicle outer panel and has an excellent bake hardenability and anti-aging property at room temperature, and a method for manufacturing a hot-dip galvanized steel plate, the method comprising a process including the steps of: winding a hot-rolled steel plate, followed by cooling at a speed of 0.002-0.027°C/sec; cold-rolling the cooled steel plate; continuously annealing the cold-rolled steel plate; and cooling the annealed steel plate in the multi-stage manner of primary to third rounds.
(FR)La présente invention concerne une plaque d'acier galvanisée à chaud pouvant servir de matériau destiné à un panneau externe de véhicule et ayant une excellente aptitude au durcissement à la cuisson et d’excellentes propriétés anti-vieillissement à température ambiante, et un procédé de fabrication d'une plaque d'acier galvanisée à chaud, le procédé comprenant un processus comprenant les étapes suivantes : l’enroulement d’une plaque d'acier laminée à chaud, puis le refroidissement à une vitesse de 0,002 à 0,027 °C/sec ; le laminage à froid la plaque d'acier refroidie ; le recuit en continu de la plaque d'acier laminée à froid ; et le refroidissement de la plaque d'acier recuite en plusieurs étapes d’un cycle primaire jusqu’à un troisième cycle.
