Abstract: An ultra-fast quenching device for rapidly quenching material includes a housing for defining a quenching area. A plurality of inlet ports are disposed in the housing and are generally evenly distributed within the housing for controlling the locations and amounts of quenching fluid discharged against a surface of material disposed in the quenching area. A plurality of exhaust ports are disposed interstitially among the inlet ports for removing quenching fluid local to the inlet ports to control the rate and profile of heat transfer, from the material to the quenching fluid, across the surface of the material.
