A thin coherent, high pressure volume, curtain water wall of liquid is applied in a transverse direction across a surface of a strip in a hot rolling mill to uniformly remove oxide scaling from the strip's surface. A header is designed to have several passages which produce several discrete liquid flows which are directed into a pressure equalization zone prior to their entering the nozzle section of the header to create upon the flow's exiting from the nozzle section a curtain wall of fluid having a thickness which delivers a uniform sufficient impact force against the strip's surface for the descaling process thereof.
