Furnaces for strip processing linesCarbon steel
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.
Sheet CAL
Combination CGL/CAL
Final annealing lines for electrical steel
From 50,000 to 1,200,000 tons/year

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
