Abstract

A nozzle beam for descaling or cooling metal strand material, particularly rolling stock, includes an inlet for the product treatment liquid and an additional inlet for a device cooling liquid, an outlet for the device cooling liquid, and a switching member for opening and closing the device cooling liquid outlet. The switching member is automatically switchable through a device cooling liquid pressure which controls the state of operation of the nozzle beam.
