Hydromechanical Descaling

Please choose from descaling nozzles, headers, and system audits.

Nozzles

Nozzles

Lechler descale nozzles have become the first choice in a growing number of mills. Their highly focused spray pattern achieves superior impact and stripping power using the least water and energy.

Descale Header Fabrication

Descale Header Fabrication

Lechler’s capabilities include the engineering design and fabrication of Descale headers to optimize scale removal.  Lechler’s descaling headers can be as simple as a pipe with nozzle bases welded in place or as elaborate as a complete enclosure with headers, guards, strip guides and scale removal equipment.  Designing and fabricating descaling headers require more than pipe welding skills. Our engineers understand the critical elements that become part of each header design:

  1. Material selection
  2. Optimal pipe size and wall thickness
  3. Fitting and connection design
  1. Appropriate pressure vessel code compliance
  2. Post weld processes and stress relief
  3. Optimized nozzle placement and alignment

Regardless of the product shape and header configuration, our experience has helped us create systems with outstanding performance and durability while remaining cost effective. Lechler’s engineers will work with you to analyze your application, and will provide sound recommendations to satisfy your mill needs

Descale System Audits

Descale System Audits

Over the life span of a rolling mill, the requirements in terms of product quality and the range of steel grades may change significantly. In particular, the capability of the installed Descale system needs to be investigated as one of the key technology areas when it comes to process modifications and surface quality improvements. Lechler’s Descaling system audit is a systematic and structured approach to determine how existing nozzle and header arrangement, operational and maintenance practices, and process data influence the surface quality. From beginning to end, Lechler can provide not only a baseline of your current systems but also optimization from the nozzle to the header layout. A total Descaling System Optimization.
