Directly Forming to Square and Rectangular Tube Mill
The square or rectangular shaping is formed out before the tube welding, with important advantages in terms of power and material cost reduction.
Great flexibility and possibility of modify the tube dimensulerion without any roll change (in forming - welding - sizing - straightening) for any size included into the mill size range.
Extreme reduction of mill set up time.
Elimination of all cost for roll sets.
Increase of productivity and reduction of stock and relative costs.
Reduction of manpower thanks to the complete automatization of the mill operation and adjustments.
Minimal and easy maintenance.
Display with automatic illustration of tube section for each production step.
Easy use of software for set up of any production parameter, including tube angle radius.
Technological Flow: Strip coil→ Uncoiling →coil peeler → pinch & Leveling →Shearing and butt welding → accumulator → Forming → Welding → bead remover →water cooling →Sizing → Turks head → Flying saw cutting → Tube collecting.
