Original abstract

High energetic water jets sprayed from nozzles are used for scale removal. Special nozzles with flat and very narrow jets for high feed pressure are used. This process, called descaling, is used in hot rolling, for example. A number of jets must be used to cover the total width of a rolled strip. High quality and homogeneity of the descaling process is required. A row of high pressure descaling nozzles is often used. This paper focuses on the area where water streams from adjacent nozzles interact. Water impact measurements were taken for several nozzle configurations and the measuring technique with the results obtained is presented. The water impact pressure for multiple nozzles was computed and the results were compared to the measurements.
