| High Light | Seven-Roller Strip Leveling ，Strip Leveling Unit ，Flat Strip Tube Forming | ||
Strip that enters forming with coil set, crown or edge wave produces uneven tube, off-center weld seams and roundness defects that cannot be corrected later in the line.
Coiled strip retains a curvature memory, and any edge wave or crown creates uneven tension across the strip width, which the forming stands then amplify into pipe defects.
The ZY16 seven-roller leveler works the strip back and forth to relieve coil set and flatten crown and edge wave before forming. Feeding flat, uniform strip into the five-plus-three stand forming keeps the weld gap even and roundness consistent, especially on hot rolled coil.

The seven-roller leveler conditions strip before forming, so coil set and edge wave never reach the rolls. Feeding flat strip keeps the weld gap even and roundness consistent, which matters most on hot rolled coil where flatness variation is the biggest source of defects.
For Φ8-18mm tube production where incoming strip flatness varies and consistent forming and weld alignment are required, especially on hot rolled strip.
Choose this leveling configuration when your strip source has noticeable coil set or edge wave, common with hot rolled coil. Adjust leveler pressure to strip thickness for best results.
Hot rolled strip conversion, thin strip prone to edge wave, and any line where strip flatness limits roundness and weld consistency.
It relieves coil set and flattens crown and edge wave so strip enters forming flat, improving roundness and weld alignment.
For Φ8-18mm strip at these gauges, seven rollers provide the alternating bend work needed to relieve coil set effectively.
Yes, leveler pressure and gap are set by strip thickness and material for the best flatness.
Cold rolled strip is flatter, but the leveler still helps on any coil with edge wave or residual coil set.
Increase leveler pressure when strip shows strong coil set or edge wave, and reduce it for flat cold rolled strip to avoid over-working the surface.
No, the leveler is set to strip thickness and runs at line speed; proper leveling actually supports higher speed by feeding stable strip.
