(54)	Method and apparatus for sequentially quenching steel pipes

(57) An apparatus is provided for quenching a piece of steel including a rotatable magazine having at least one barrel for detachably holding the steel piece. A cooling medium source is also provided for supplying a cooling medium to each barrel. In one embodiment each barrel has a primary opening along its length for accepting the steel piece and closing means for selectively closing off the primary opening. Each barrel may also be equipped with a secondary opening for discharging the cooling medium. There is also provided a method of sequentially quenching pieces of steel including the steps of moving a plurality of receptacles along a cyclical path from an inlet station to an outlet station while placing a piece of steel in each receptacle as it passes the inlet station and supplying a cooling medium to each receptacle in an amount sufficient to quench the piece of steel in the receptacle prior to removing the piece of steel at the outlet station.
