An apparatus for heat treatment of impact beams for use in automobiles is disclosed. This apparatus uniformly heat-treats impact beams having a non-circular cross-section, such as an elliptical cross-section. The apparatus of the present invention comprises a step feeder, a conveying unit, a guide unit, an impact beam rotating and moving unit, a heat-treating unit, a cooling unit and feed rollers. The impact beam rotating and moving unit consists of a rotary drum and a plurality of support rolls. This rotary drum cooperates with the support rolls to move the impact beams from the guide unit to a heat-treating unit. Each of the support rolls has a tapered profile. The heat-treating unit is used for heating the impact beams from the rotating and moving unit to the center of the induction coil so as to allow the impact beams to pass through the center of the induction coil.
