Nozzles for descaling

In hot rolling mills around the world, Lechler SCALEMASTER descaling nozzles ensure the best surface qualities and low energy consumption.

Nozzle types overview

Scalemaster HPS®
New

SCALEMASTER HPS® and MiniSCALEMASTER HPS®

  • Remarkable increase of impact for better descaling
  • Better product surface quality due to higher impact
  • Reduction of descaling water flow rate possible
  • More durable tip with high mechanical strength due to window design
  • Potential of energy savings due to reduced slab/strip cooling
  • Interchangeable with all other SCALEMASTER nozzles
