Tension Leveler for 1550 mm Galvanizing Lines
This is the tension leveler configuration for a 1550 mm galvanizing line. Tension rolls at inlet and outlet stabilise tension, the roll group amplifies it, and the straightening unit works the strip in two stages until shape and mechanical properties are both improved.
- Configured for 1550 mm galvanizing lines
- Two tension rolls at inlet and outlet
- Two rows of bending components with balancing rollers
- Two stage deformation and correction
Key Benefits
What it does for a coating line.
Complete Shape Defect Removal
Bilateral wave, unilateral wave, middle wave, two rib wave, warping, buckling and latent poor shape are all addressed in one pass.
Internal Stress Evened Out
The first stage distributes residual deformation evenly and the second corrects it, so internal stress tends to uniformity.
Ready For Automotive Sheet
Strip leveled this way is used for car bodies, doors, roofs and similar components where flatness is specified.
Where It Is Used
Products and lines.
- 1550 mm galvanizing lines
- Carbon steel strip processing
- Automotive component sheet production
- Iron and steel manufacturing finishing
Who It Is For
- Galvanizing line operators at 1550 mm width
- Automotive sheet producers
- Plants replacing a leveler in an existing line
- Project teams specifying a new coating line
Problems It Solves
- Three dimensional shape defects in coated strip
- Uneven longitudinal extension across the width
- Rolling stress disorder from the mill
- Formability problems after coating
Technical Features
Machine arrangement.
Tension Stabilisation
Two tension rolls at the inlet and outlet stabilise tension and reduce fluctuations, and the roll group amplifies it.
Straightening Unit
The unit carries two rows of bending components with balancing rollers.
Two Stage Correction
Alternating deformation distributes residual deformation in stage one, and stage two corrects it fully.
Specifications
Configuration follows the galvanizing line. Scope is agreed per project.

Materials
- Welded and machined frame
- Alloy steel work, bending and balancing rolls
- Tension drive and hydraulic package
Manufacturing Process
Line Study
Coil programme, line speed and flatness target set the roll configuration.
Frame Production
Frames are welded, stress relieved and machined.
Roll Manufacture
Work, bending and balancing rolls are produced and ground together.
Assembly And Test
Roll parallelism, tension control and drive alignment are verified.
Quality Control
- Frame machining inspection
- Roll hardness and geometry records
- Tension and hydraulic system test
- Assembly alignment report
Customization Options
- Width and thickness range for your line
- Roll configuration for the flatness target
- Drive and automation interface
- Installation into an existing galvanizing line
Use Guide
- Set elongation from the incoming flatness measurement
- Keep tension within the specified band
- Check balancing roller settings after product changes
- Regrind work rolls before surface wear prints onto the strip
How It Compares
Against other configurations.
| Roller leveling without tension | Tension plus bending redistributes internal stress rather than only bending out the visible defect. |
|---|---|
| Single stage correction | Two stage correction distributes residual deformation before removing it, which holds the result after cutting. |
| Wider or narrower machines | A machine dimensioned for 1550 mm matches the line width exactly, avoiding edge effects or wasted capability. |

Is this only for 1550 mm lines?
This configuration is built for a 1550 mm galvanizing line. Other widths are configured the same way from your line data.
Which defects does it remove?
Bilateral wave, unilateral wave, middle wave, two rib wave, warping, buckling and latent poor plate shape.
How does the two stage sequence work?
In the first stage the strip undergoes alternating deformation so residual deformation is distributed evenly. The second stage corrects it fully, improving shape and mechanical properties.
What products is the strip used for?
Carbon steel sheet for car bodies, doors, roofs and similar components, among other applications.
Can it be installed in our existing line?
Yes. Send the line layout, available length, speed and tension data.
What do you need to quote?
Strip width and thickness range, steel grade, line speed, incoming and target flatness.
