Product Introduction

Overview

Flattener machine for ERW mill line serves as an indispensable auxiliary processing unit integrated into ERW pipe manufacturing production lines.
Designed specifically for leveling incoming hot-rolled and cold-rolled steel strips uncoiled from steel coils, it effectively corrects inherent material defects including uneven surface undulation, longitudinal camber, edge curling, edge buckling and lateral warpage generated during coil slitting, transportation and storage.
By thoroughly flattening and straightening the entire strip width with precise roller compression before the strip enters the tube forming section, it maintains consistent flatness and uniform straightness of the raw material throughout continuous production.
Consistent strip flatness greatly stabilizes subsequent tube forming geometry, controls forming gap uniformity, avoids strip deviation and misalignment, significantly suppresses common high-frequency welding flaws such as weld seam offset, inconsistent weld clearance, cold welding, incomplete penetration and weld overlap, and delivers consistent dimensional stability for finished ERW pipes.

Our Advantages

  • 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.
  • Flexible Adjustable Design: Supports precise roll gap adjustment, easy parameter calibration for different raw materials and production standards, ensuring flexible and efficient production.
