ANNEALING AND PICKLING

The pickling and annealing process of the hot strips consists of three main phases:

  • Annealing: This can be done in passive furnaces, bell ovens, and directly in line. The aim is to release the internal stresses of the structure created during hot rolling.
  • Mechanical pickling: This is carried out with a sandblaster and afterwards, with abrasive brushes.
  • Chemical pickling: This is done in tanks with acid solutions (H2SO4 + HF).
