Cold Roll Forming Line

Cold Roll Forming Line description
This equipment is specially used for producing Φ19-Φ76mm, 0.8-3.0mm high frequency straight seam welded tube and corresponding square tube and special-shaped tube (δ≤2.5mm). The composition of equipment is from uncoiler to fixed length cutting saw. Rolling speed can be adjusted correspondingly within suitable range of tube diameter and wall thickness.

1.Applicable material:
(1) Hot or cold-rolled steel strip
(2) Material: Low-carbon steel, low alloy steel
(3) The thickness of steel strip: 0.8-3.0mm
(4) The width of steel strip: 60-240mm
(5) I.D. of steel coil: Φ450-Φ550mm
(6) O.D. of steel coil: Φ800-Φ1200mm
(7) Maximum weight coil: 2500kgs

2.Dimension range of processing steel tube:
(1) O.D.: 19-76mm
(2) Wall thickness: 0.8-3.0mm (square tube and special-shaped tube δ≤2.5mm)
(3) Length: 4-8M

3.Milling speed: 20-100M/min(choose different speed as per different pipe diameter and thickness)

4.Product (steel tube) process flow:
Raw material (steel coil) → uncoiling → shearing and end welding → material accumulating → non-power leveling → mill-forming → high-frequency welding → removing burrs outside of weld seam → cooling → sizing → roughly straightening → fixed length cutting → finishing tube
