Stress relieving

  • Gloeien tot een afmeting van Ø 2600 * 3500 mm.
  • Gloeien tot een stukgewicht tot 20.000 kg.
  • Dominial heeft dit proces volledig geautomatiseerd waardoor ze de tijd-temperatuur nauwkeurig kunnen registreren.
  • Dominial beschikt over 16 ontlaat/gloei ovens.

The process

The annealing process comprises the treatment of a workpiece at a certain temperature and with a certain retention time, followed by cooling that is dimensioned so as to attain the desired material properties.

Stress relieving is an annealing process performed at sufficiently high temperatures (however, with hardened and tempered steels, it is performed below the last tempering temperature), with the aim of reducing internal stress without making any fundamental changes to the microstructure or the mechanical properties.
