This Steel square tube forming machine is specially used for producing Φ70-Φ127mm, δ1.5-6.0mm high-frequency straight seam welded pipe and corresponding square pipe and special-shaped pipe (δ≤4.5mm).The composition of Steel square tube forming machineis from uncoiler to fixed length cutting saw. Rolling speed can be adjusted correspondingly within suitable range of pipe diameter and wall thickness.
Steel square tube forming machine material:
(1)Hot or cold-rolled steel strip (As per GB708-88)
(2)Material: Low-carbon steel, low alloy steel, δs≤345Mpa,δb≤610Mpa
(3)The thickness of steel strip: 1.5-6.0mm (As per GB708-88)
(4)The width of steel strip: 200-400mm
(5)I.D. of steel coil: Φ500-Φ600mm
(6)O.D. of steel coil: Φ1000-Φ1500mm
(7)Maximum weight coil: 4500kgs
1.3Dimension range of processing steel pipe:
(2)Wall thickness: 1.5-6.0mm (square pipe and special-shaped pipe≤4.0mm)
1.4 Steel square tube forming machine process flow:
Raw material (steel coil) → uncoiling → Flattening → leveling → shearing and butt-welding → material accumulating → mill-forming → high-frequency welding → removing burrs outside of weld seam → cooling → sizing → roughly straightening → fixed length cutting → finished pipe → run-out table
Milling speed: 15 - 50m/min
1.5High-frequency equipment power: 500 KW(Solid state
