Study of Water Jet Collision of High Pressure Flat Jet Nozzles for Hydraulic Descaling

Popis výsledku v původním jazyce

One of the most effective methods for descaling hot-rolled steel products is performed using high pressure flat jet nozzles. These descaling nozzles are arranged in rows in hot rolling mills and are set in such a way that each adjoining pair of nozzles creates an overlapping area of water jet streams. Good homogeneity of the pressure distribution over the width of the hot-rolled plate is often used as an indicator of quality of the homogeneity of descaling. The presented laboratory measurements examine one pair of adjoining nozzles with a particular focus on the pressure distribution in the overlapping area. This paper deals with one particular setting of a pair of descaling nozzles with zero offset angles for the jet streams. A measured pressure distribution and an outcome of an erosion test on an aluminum plate are presented and discussed. The erosion test shows that spots with higher pressures do not necessarily result in a higher amount of removed material during an erosion test. The erosion test differs from the expected outcome in such a way that a detailed discussion of this phenomenon is outlined with possible explanations.
