Descaling by Pulsating Water Jet

Popis výsledku v původním jazyce

Descaling is the process when scales are removed by water jet. In Academy of science in Ostrava, they have patented device called pulsator which can add to the water some extra energy in the form of high-frequency pressure pulses which disintegrate flatwater jet. This paper deals with a new study of removing scales using pulsations and its comparison with descaling process without pulsating water jet. There are two main factors the thermal shock and the impact pressure applied by the impinging water onto the surface. During cold rolling is important only impact pressure. The descaling by pulsating water jet was also tested on the sheets generally used during cold rolling, because pulses create very short pressure peaks in the impact area higher than 300 MPa. While during the descaling without pulses is impact pressure approximately 1 - 5 MPa. Heat transfer and descaling tests were performed on carbon steel plate and steel sheet with a high percentage of silicon. Just these scales are
