Abstract
Recuit en continu d'un acier à très faible teneur en carbone, destiné à un emboutissage profond, le procédé comprenant le chauffage d'une tole d'acier depuis la température ambiante jusqu'à sa température de recristallisation, la régulation de la température de la tole chauffée par un chauffage rapide jusqu'à une température maximale de chauffage recherchée, et ce avec une précission d'au moins plus ou moins 10 degres, et ensuite le refroidissement rapide, sans égalisation, et finalement un refroidissement jusqu'à la température ambiante.Continuous annealing of a very low carbon steel, intended for deep drawing, the process comprising heating a sheet of steel from ambient temperature to its recrystallization temperature, regulating the temperature of the sheet heated by rapid heating to a maximum desired heating temperature, and this with a precission of at least plus or minus 10 degrees, and then rapid cooling, without equalization, and finally cooling to the temperature ambient.
