Cooling arrangement

摘要

A cooling arrangement, especially but not exclusively suited for cooling rolled stock such as wires and bars, has two end members provided with axially aligned passages through which a workpiece can travel. The end members are connected by an annularly arranged series of bars between which spaces are left free so that cooling fluid admitted into contact with the workpiece can rapidly flow off again. The space surrounded by the bars converges in the direction of travel of the workpiece. Upstream of one end member is provided a fluid admitting element formed with a workpiece guide passage which is divergent-convergent as considered in the travel direction of the workpiece. A fluid inlet arrangement has an inner wall bounding the passage and provided with circumferentially spaced slot-shaped openings which communicate with the divergent part and extend toward the convergent part, and an outer wall surrounding the inner wall and bounding with the same an annular fluid chamber from which the slot-shaped openings receive fluid.
