Abstract
Apparatus for heat-treating an elongate structural body part made from a blank compressed while being soft or from steel strip of hardenable 22 Mn B5 mod. steel sheet with a thickness of 1 mm to 3 mm, includes an apparatus for positioning the structural body part in substantially upright disposition. Placed in surrounding relationship to the structural body part is an induction element which can move from bottom to top, thereby being able to follow a contour of the structural body part and allowing to at least partially heat the structural body part to an austenitizing temperature suitable for hardening. Disposed adjacent to the induction element is a cooling unit which follows the induction element in movement direction. The induction element and the cooling unit are moveable relative to one another and connected to a tool carriage which is mounted to a column for movement in a vertical direction, in a transverse direction to the column and about a horizontal axis.
