Abstract
An apparatus for heat treating elongate articles including a furnace arranged above a quenching liquid reservoir and guide elements for guiding heated elongate articles from the furnace into the quenching liquid. In a preferred embodiment, the furnace utilizes a plurality of elongate tubes which receive detachably held elongate articles. Upon release, the elongate articles fall while oriented vertically by the guide elements into the quenching liquid. Warping or bending of the elongate articles is thereby prevented during the transfer from the furnace to the quenching liquid.
