Effect Of Water Jet Nozzle Lead Angle On Descaling Efficiency
Nozzle design, water pressure, and lead angle are critical for efficient descaling. In the industry, scale removal through water jet descaling using a nozzle lead angle of 15° is considered as optimal. However, variations in scale removal efficiency were not quantified. Experiments were performed using a laboratory CNC-controlled descaling system. Low- alloy steel plates were reheated at 1065°C in an atmosphere-controlled induction furnace and then descaled using two nozzle types and three attack angles in all cases. Statistical characterization of residual oxide coverage was performed using SEM analysis in a cross-section of the plate. Recommendations to increase descaling efficiency are presented.
