Abstract
L'invention concerne un procédé de trempe d'une pièce (1) avec au moins deux inducteurs (2), sachant que la couche de bord (4) à tremper est exposée aux champs électromagnétiques des inducteurs (2) et est échauffée jusqu'à la température de trempe souhaitée par un mouvement relatif entre les inducteurs (2) et la pièce (1). Selon l'invention, la puissance de chauffage des inducteurs (2) et la vitesse du mouvement relatif sont mutuellement adaptées de telle sorte que la totalité de la couche de bord (4) à tremper est échauffée uniformément de bout en bout.
