Annealing and galvanizing lines

Energy savings in hot-dip galvanizing lines

Multiphase steels, which are high strength and very ductile, are increasingly being used for car components. These high-strength yet easily deformable steels must meet the highest quality requirements for use in automobiles.

In the lines, account is taken of the stringent demands on surface quality. This commences with cleaning, which is followed by surface-friendly annealing, and high-grade coating technologies for the application of a zinc layer, passivation, or preserving oils. Advanced annealing and cooling strategies are implemented, together with a skin-pass mill stand for targeted post-treatment, in order to achieve outstanding material strengths.
