Présentation générale
Notre Automatic 9 Roller Strip Leveler (also referred to as a strip flattener) serves as critical entry‑section equipment for a full ERW tube mill line. Mounted immediately after the uncoiler, it prepares steel strips ahead of forming and welding operations. Purpose‑built to remove coil‑set curvature, edge waviness and residual internal stress from hot‑rolled and cold‑rolled steel coils, this flattener produces consistently flat strip feed for downstream tube forming, effectively stabilizing weld‑seam quality and reducing pipe rejection rates.
Engineered for carbon‑steel, alloy‑steel and galvanized‑steel strips, our ERW flattener features heavy‑duty hardened leveling rolls and adjustable pinch rolls. It enables synchronized automatic operation with the uncoiler, shear‑butt welder and accumulator throughout the ERW pipe‑making workflow. Hydraulic pressure adjustment allows fast parameter changeover for varying strip thickness and width, accommodating different ERW mill capacities and OCTG pipe‑manufacturing demands.
Constructed with a heavy welded frame, the unit facilitates simple roll replacement and routine maintenance for long‑term non‑stop heavy‑load operation. Custom‑tailored configurations can be supplied based on your actual strip specifications and plant layout. Please contact us for technical datasheets and quotations for your ERW tube mill project.


Nos atouts
-
Precision Leveling Performance: Adopts multi-roll staggered leveling structure to apply uniform alternating bending force on steel strips, thoroughly correcting strip deformation and ensuring excellent flatness without damaging material texture.
-
Stable Line Operation: Synchronizes perfectly with the full ERW production line speed, realizing continuous, jitter-free strip feeding, effectively avoiding production stagnation caused by unflat materials.
-
Improve Final Pipe Quality: Optimizes strip flatness consistency, guarantees precise weld seam alignment and uniform welding, greatly reduces welding defects, pipe ovality and finished product rejection rate.
-
Wide Material Compatibility: Adaptable to carbon steel, galvanized steel, alloy steel and other common pipe-making materials, suitable for various specifications of strip thickness and width, meeting diverse tube production demands.
-
Durable & Low Maintenance: Equipped with high-strength leveling rolls and rigid mechanical structure, featuring wear resistance, stable operation and long service life, minimizing daily maintenance and production costs.
-
