Original Abstract

The latest research in descaling brought new findings about dynamic features of the process. The continuous water jet formed by a descaling nozzle has complicated and variable qualities not visible to the naked eye. A water jet is formed by clusters of droplets moving at high velocity. The theory of the "water hammer" must be used when the descaling process is studied. Results show that in the impact area, one can observe pressure peaks of several hundred Mpa's, lasting microseconds per peak. This finding can modify most existing concepts of descaling and the impact on current theory is discussed. Structure of the descaling jet can have equally as much importance as impact pressure.
