Abstract
The present invention provides a quench for cooling hot sheet material. The quench includes a plurality of generally horizontally extending, spaced apart nozzle assemblies, each having a longitudinally extending air supply conduit with orifices extending to an outer surface of the conduit. A first plenum is interconnected to a first end of each of the conduits and a second plenum is interconnected to a second end of each of the conduits to allow cooling fluid to pass from the plenums into each of the nozzle assemblies through the conduit. The plenums are located at positions spaced laterally outward from the nozzle assemblies.
