摘要： A reduction of the unevenness of a temperature increase at the end of heating work can be achieved without specific equipment, and with securing the shortening of the working time, which is an advantage of a bulk heating.When a region to be heated of an article made of a thin sheet is heated inductively so that the whole region thereof reaches a temperature equal to or more than a target temperature using an inductive portion of a heating inductor, to which a high-frequency current is applied by a power supply device, by stopping or reducing temporarily the power application of the high-frequency current to the heating inductor during the temperature increase, a temperature difference in the region to be heated is reduced so that the unevenness of the temperature increase at the end of the heating work is reduced by the step of reducing the temperature difference.

When a region to be heated of an article made of a thin sheet is heated inductively so that the whole region thereof reaches a temperature equal to or more than a target temperature using an inductive portion of a heating inductor to which a high-frequency current is applied by a power supply device, by providing a period to stop or reduce temporarily the power application of the high-frequency current to the heating inductor during the temperature increase, a temperature difference in the region to be heated is reduced so that the unevenness of the temperature increase at the end of the heating work is reduced by the step of reducing the temperature difference.

摘要： A press formed article such as a center pillar or the like for a vehicle having a demanded strength distribution achieved by hardening through induction hardening or the like, and a method and an apparatus for performing induction hardening on the press formed article. The center pillar (10) being a press formed article has an intermediate top portion (11) which extends in a longitudinal direction of the center pillar (10), and two blade portions (12) which are both bent in the same direction from both sides of the intermediate top portion (11), in which hardening regions (Q) are provided on both sides of the intermediate top portion (11), extending over the intermediate top portion (11) and the blade portions (12). These hardening regions (Q) hardened by the induction hardening apparatus are regions in a form which widens toward the end and continuously expand from the upper portion to the lower portion of the center pillar (10). Therefore, the ratio between the hardening regions and non-hardening regions changes in the longitudinal direction of the center pillar (10), resulting in a demanded strength distribution.
