Original Abstract

High pressure descaling nozzles are used mainly for removing oxides from hot steel products. The homogeneity and intensity of water pressure distribution on the oxidised surface are very important characteristics for a description of nozzle characteristics. The higher the water impact is the more scales are removed and the surface is cleaner. The results of water impact depend not only on the used nozzle but also on the used water stabilizer and geometry of water chamber in which the nozzle with the stabilizer is mounted. To analyse the real water pressure distribution a special measuring device was used that enables us to scan pressure distribution of the spraying nozzle. Two different nozzles were used, each with a different construction of a stabilizer. The nozzles with the stabilizers were mounted in the water chambers with different geometries. It was confirmed that water chamber geometry has a slight effect on water pressure distribution. It was also found that for some geometry of the stabilizer the water chamber geometry has a bigger effect and for some smaller. The measured values are also compared with numerical simulations in the water chamber and the stabilizer.
