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.
Computerized Roll Positioning for quick adjustment of roll setting without any roll change (in forming - welding - sizing - straightening) for any size included into the mill size range.
Automatic roll setting on the basis of mechanical forming theory and experience of long term operation by computer for size and wall thickness change.
Roll adjustment is done by Computer
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.
