Abstract

In order to provide a spray boom with a plurality of spray nozzles for a hydraulic descaling facility with which a high temperature constancy from beginning to the end of the rolling stock is insured and a too rapid cooling of the surface is prevented, it is proposed, in accordance with the invention, to assign a check valve to each spray nozzle.
