ABSTRACT:
An apparatus for cooling a workpiece, especially a continuous rolled non-flat workpiece includes a cooling passage having an inlet for receiving the workpiece and an outlet for discharging the workpiece, the cooling passage having a central axis and further including an inlet for introducing a cooling medium to the cooling passage, and an outlet for removing the cooling medium from the cooling passage, the cooling medium inlet being arranged relative to the central axis of the cooling passage so as to induce a substantially helical flow of cooling medium around the central axis from the cooling medium inlet to the cooling medium outlet, the cooling medium outlet including a chamber having an expanded flow area, whereby pressure and velocity of the cooling medium in the cooling passage are controlled so as to provide accelerated cooling of the workpiece. Further according to the invention, the cooling medium inlet includes a first cooling medium inlet and a second cooling medium inlet, the chamber being disposed between two segments of the cooling passage between the first and second cooling medium inlet, the first cooling medium inlet being arranged so as to induce a first substantially helical flow of cooling medium around the central axis toward the chamber, and the second cooling medium inlet being arranged so as to induce a second substantially helical flow of cooling medium around the central axis toward the chamber.
