Abstract
A method and apparatus for quenching steel plates after they come from an austenitizing furnace. The plates are stopped and their surfaces flooded with large volumes of water applied almost instantaneously. The valves which control water application are operated by pneumatic operators so that they move from a closed position to a full open position almost instantaneously. The invention overcomes the tendency of plates to buckle during quenching and cools the plate at the maximum rate for the water pressure and volume available.
