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.

P_ROBO_X^® technology

Hot-dip galvanizing of advanced and high-strength steels with high silicon and manganese contents

The PrOBO_x^® technology, an easy-to-apply pre-oxidation process offered by SMS group, effectively counteracts wettability problems while galvanizing high-alloyed modern steel grades.

X-Pro^®-Laserschweißmaschine

Schnelles, sicheres und erfolgreiches Schweißen anspruchsvoller Stahlgüten

Präzise, schnell und verlässlich: die X-Pro^®-Laserschweißmaschine der SMS group im fortlaufenden Betrieb für schwer schweißbare Stahlgüten.

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 positioning	›	No unnecessary wear
Brush-on-brush-concept	›	Effective use of space
Intelligent media management	›	Saving of water

Galvanizing technology

Air-knives for highest surface qualities

Homogenous coating 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 save zinc and cut production costs.
