Abstract

La présente invention concerne un cuiseur comportant une plaque composite à trois couches et le procédé de fabrication correspondant. Le cuiseur comprend l'entité cuiseur composée d'un corps de cuiseur et d'un fond de cuiseur. Le corps de cuiseur de l'entité cuiseur est une plaque métallique composite à trois couches composée d'une couche intermédiaire constituée de l'acier inoxydable 409 ou 430 et d'une couche intérieure et d'une couche extérieure constituées d'un alliage d'aluminium. Le fond de cuiseur de l'entité cuiseur est une plaque métallique composite à deux couches composée d'une couche intérieure constituée de l'alliage d'aluminium et d'une couche de fond constituée de l'acier inoxydable 409 ou 430. Le procédé de fabrication de cette invention comprend les étapes suivantes consistant d'abord à sélectionner la plaque métallique composite à trois couches composée de la couche intermédiaire constituée de l'acier inoxydable 409 ou 430 et des couches intérieure et extérieure constituées de l'alliage d'aluminium, à étirer la plaque métallique composite et à mettre en forme l'entité cuiseur comprenant le corps de cuiseur et le fond de cuiseur. Ensuite, les surfaces intérieure et extérieure sont soumises à certains traitements de surface tels que l'oxydation ou la peinture par pulvérisation. Enfin, l'alliage d'aluminium de la couche extérieure sur la surface de fond du cuiseur mis en forme est retiré et surfacé de façon que la couche d'acier inoxydable soit exposée.
