Abstract: front page image
(EN)The present invention includes continuously shifting the position of a section, which is to be locally induction-heated, of steel having a martensite structure or a bainite structure while locally induction-heating the section at a temperature between the Ac3 transformation point and 950 degrees Celsius inclusive, locally and continuously deforming the locally induction-heated section of the steel having the martensite structure or the bainite structure, and continuously hardening the locally and continuously deformed section of the steel having the martensite structure or the bainite structure.
(FR)La présente invention comprend un décalage continu de la position d'une section, qui doit être chauffée par induction localement, d'un acier ayant une structure martensite ou une structure bainite tout en chauffant par induction localement la section à une température comprise entre le point de transformation Ac3 et 950 °C inclus, une déformation locale et continue de la section chauffée par induction localement de l'acier ayant la structure martensite ou la structure bainite, et un durcissement continu de la section déformée localement et en continue de l'acier ayant la structure martensite ou la structure bainite.
(JA)マルテンサイト組織またはベイナイト組織の鋼材を、局所的に誘導加熱する部分の位置を連続して移動させつつ、Ac3変態点以上950℃以下の温度に局所的に誘導加熱し、マルテンサイト組織またはベイナイト組織の鋼材の局所的に誘導加熱された部分を局所的に連続して変形し、マルテンサイト組織またはベイナイト組織の鋼材の局所的に連続して変形された部分を連続して焼入れする。
