ABSTRACT:
An apparatus for rapidly quenching substantially flat metal workpieces which have been heated during a heat treatment process is disclosed. The apparatus comprises a substantially flat plate having a plurality of vapor relief apertures therein, a wick element which overlies the plate so that it substantially covers the apertures, and means for supplying a coolant such as water, to the wick element so that the coolant is substantially evenly dispersed therein. The apparatus is operable for urging a heated workpiece into face to face engagement with the wick element to effect intimate contact between the workpiece and the coolant in the wick element. As soon as the workpiece contacts the coolant in the wick element, at least a portion of the coolant is substantially instantaneously vaporized to effect rapid cooling of the workpiece, the vaporized portion of the coolant escaping from the wick element through the relief apertures in the plate so that it does not impede the quenching process. The apparatus is operable for rapidly and uniformly cooling a substantially flat metal workpiece through the hardening range of the metal from which it is constructed to enhance the hardness, flexibility, and durability of the metal.
