Date Jun. 20, 1996A pressurized water drain apparatus, for cooling rolling stock, has a pressurized cooling pipe heat exchanger for applying water through nozzle heads onto the rolling stock in a parallel flow and a storage chamber at an outlet of the cooling pipe heat exchanger. The storage chamber includes a deflection system with guiding funnels, a rolling stock outlet and a water outlet. A steam-barrier chamber is connected to the rolling stock outlet of the storage chamber and has a guide funnel with a diameter B and a bifurcated pipe with an input at a top of the steam barrier-chamber and ducts extending down sides of the steam-barrier chamber with outlets opening into the steam-barrier chamber below the guide funnel a distance A. The steam-barrier chamber further has lower inclined walls converging at an outlet connected to a drain shaft and a funnel structure with inclined walls substantially parallel to the lower inclined walls forming channels between the lower inclined walls and the funnel structure with top inlets disposed beneath the outlet openings of the ducts. A pipe connects the water outlet of the storage chamber to the bifurcated pipe to channel water from the storage chamber through the ducts to pass through the channels defined into the drain shaft to produce suction for drawing water from the steam-barrier chamber. In an advantageous embodiment the inclined walls are inclined in the range of 20 DEG to 50 DEG and distance A ranges from B to 2B.
