Original Abstract

High energetic water jets sprayed from the nozzles are used for scale removing. Special nozzles with flat and very narrow jet for high feeding pressure are applied. This process called descaling is applied, for example, in hot rolling. Number of jets must be used to cover the total width of a rolled strip. Good quality and homogeneity of 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 conducted for several nozzle configurations and the measuring technique with the results obtained is presented. The water impact for multiple nozzles was computed and the results were compared with the measurements.
