High precision rectangular pipes welding erw tube rolling machine
The HG76 mill is used to manufacture of round pipe of Φ25mm-Φ76mm with thickness of 1.0mm-4.0mm from cold-rolled and hot-rolled coil strip by means of unclosed tubular blank with its subsequent welding into tube, edge heating by means of solid state high-frequency welder, longitudinal seam welding in rolls of tube welding machine, cooling, further sizing or shaping and on-stream cutting of endless tube in measured lengths.
The High precision tube mill has some advantages as follow:
between level roller jumps 0.01,between frame and slide clearance ≤0.02mm, frame vertical degree ≤0.05, each frame parallel degree ≤0.1mm
steel pipe diameter and roundness error≤0.08mm.
Product Process:
material(steel coil)→uncoiler→shear and welder→horizontal(or cage) accumulator→forming mill→
HF soild welder→sizing mill→rounghly straightening(turkey head)→cut off machine→run out table
