Technical Highlights

Multi-phase 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.

Annealing and galvanizing lines from the SMS group are characterized in particular by the excellent quality of the end product, high efficiency and economy, as well as enormous capacities. In recent years various improvements and new technical solutions have been developed, particularly regarding line concepts, furnace technology, galvanizing technology and post-treatment.

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 millstand for targeted post-treatment, in order to achieve outstanding material strengths.

Cleaning technology

Clean surfaces are a necessary pre-condition for high-quality material
Oscillating brushes Longer lifetime, better cleaning
High-pressure cleaning No wear and high cleaning effect
Smart brush positioningNo unnecessary wear
Brush-on-brush-concept Effective use of space
Intelligent media management Saving of water

Galvanizing technology

Air-knives for highest surface qualities
  • Outstanding homogenous coating results using a minimum metallayer
  • Special features allow highest surface qualities (C surfaces) and resource savings
  • Stable strip run in the air-knife due to electromagnetic strip stabilizer

A key quality characteristic of the hot-dip galvanizing lines is the accuracy of the coating thickness; complying with narrow coating tolerances means you also save zinc and cut production costs

It’s also to your advantage because our entire scope of supply and services – from plant engineering to process engineering, electrics and automation, manufacturing, assembly, Plug & Work testing, commissioning, right through to after-sales service – is geared to your specific requirements.


Zinc pot maintenance

Roll coatings, arm repairs, spare parts

The SMS group repairs and restores zinc pot equipment. Results: Reliable performance and superior final product quality

Scope of Service:

  • Resurfacing and coating of rolls
  • Replacing of bearing systems.
  • Repairing and rebuilding of complete pot rigs, arms, rolls and bearings.

Campaign life or up to 8 weeks. Reduced roll inventory and overall maintenance costs.

Coated furnace rolls

Strong surfaces to endure thermal and mechanical stress

Peel-off effects damage the furnace roll and thus the strip surfaces causing the
final product to be unusable e.g. for automotive applications. With its wide range of surface coating for the intended use, SMS prolongs the service life of furnace rolls and guarantees a high strip quality.

Coating materials:

  • Metal alloy
  • Cermet compound material 
  • Ceramics

Pick-up reduction by up to 93% increases campaign life.
