Products

Continuous galvanizing line (CGL)Wide range of heating technologies: radi-

ant tube (RT), direct-fired furnace (DFF),

induction heating, electrical heating for dif-

ferent applications like architectural sheet-

ing, domestic appliances, exposed and

non-exposed automotive parts.

Horizontal, vertical or L-shaped lay-

outs

From CS to HSS/AHSS, GI, GA, GL

From 25,000 to 500,000 tons/year

Continuous annealing line(CAL)Based on patented technology for the

ANDRITZ Selas differential rapid jet cool-

ing system (DRJC); for domestic applica-

tions, automotive AHSS, electrical steel,

and tin plating.

Technologies

Direct-fired furnace (ANDRITZ Selas technology)

Carbon steel strip processing line

Our know-how

More than 110 years of experience

Highly qualified engineering team

3D engineering simulation tools

Technology for highest strip surface quality

Predictive math models for optimized operation

Direct-fired furnace (DFF) Heating to the annealing temperature in

only one vertical pass

Cleans the strip by reduction of oxides

and elimination of iron fines and oils, ma-

king any cleaning section unnecessary

Very fast response to production

changes

Uniformity of heating across the strip

width; no buckling due to heating

Controlled pre-oxidation for AHSS

Ultra-low NOx emission

Radiant tube heating (RTH) Thin-wall radiant tubes for low thermal

inertia

Recuperative and regenerative low and

ultra-low NOx burners

Push-pull control systems

Long-life radiant tubes

Anti-buckling systems

Differential rapid jet cooling (DRJC)Strip cooling with:

Cooling rates up to 140 C/sec with HNx

at 5% H2 for a strip thickness of 0.8 mm

and a temperature drop from 720 C to

350 C

Automatic control of the temperature

profile and a maximum deviation of 3 C

Across the strip width no buckling due to

cooling (patented system)

Air cooling Wide range of designs for perfect tempe-

rature uniformity

After-pot gas jet cooling, specially desi-

gned to avoid strip flutter

Water quenching and drying to reduce

strip temperature in the downstream pro-

cess
