Nozzles for descaling

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

Lechler nozzles for descaling

Nozzle types overview

Scalemaster HPS®
New

SCALEMASTER HPS® und 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
